Catching Water

In this day of cruising with watermakers, the art of catching rain water is slowly being lost. But watermakers take power, are maintenance-prone, and no matter how good a job they do, there is just nothing like a fresh glass of freshly caught rainwater.

Aboard BEOWULF we now have two Village Marine “Little Wonders”. These crank out between 16 and 18 gallons an hour, and we typically run the waternaker one to two hours per day. That’s not too hard to take. But consider what we can do with a single, moderate squall.

Catching rainwater

Often the combination of deck drains and holes in the toe rail make it impractical to catch water off the deck. That was the situation we found with INTERMEZZO. In this case, you can use various combinations of awnings to catch your rainwater. The key is to take this into account when having your awnings built.

Globalstar

I’m fascinated by your comments about Globalstar–do you think it’s a viable option for our cruise despite the company’s problems? I’m reluctant to buy a $1000 SSB modem if we can get satellite service instead…Best regards, Candace

Life Line Connections

The most costly and least reliable segment of your life lines is the terminating hardware. These are typically stainless on stainless turnbuckles, and are subject to galling and cracking over time. A much better approach is now possible with high-modulus line, like Spectra. Make up your life lines with nicro pressed end fittings, and then tie these in place using multipe wraps of Spectra line. There is a second advantage to this system. If you ever have a crew overboard, and need to get rid of the lifelines in a hurry, you can do so by cutting the lashings on one end.

Taking this approach a step further, when we replaced the life lines on BEOWULF this year we did so with Spectra line. It is about the same cost as the stainless steel we¹ve used in the past, a lot lighter, and not subject to corrosion like stainless steel wire.

Seagoing Washing Machines

Probably the most critical piece of cruising gear, the one which we cannot do without, is the washing machine. (Okay, Steve would do without, but Linda is much more civilized.)

For years we’ve used the Spendide washer/drier combo on various boats we’ve built. The unit on Beowulf has 28,000 miles on it. Since the motion at sea is even harder on the innards than anything which happens in actual washing, it has finally been starting to show its age.

Electronic Charting

The marriage of the PC, GPS, and electronic charts is a double-edged sword. The system, when it is operational, definitely reduces workload for a short-handed boat, and helps with navigation in tight spots.

But the system is not foolproof. One must use the same care with these systems as with conventionally plotted positions.

Comments on Using the WH Polar Pilot

We’ve been using the WH Polar Pilot option now aboard our 78′ ketch Beowulf for the past year. To say that the features in this option improve the breed is a major understatement. We think the performance and comfort enhancements are nothing short of revolutionary.

Battery Maintenance

We’ve been using Trojan “Traction” batteries for years in our yachts. These industrial strength batteries are designed for a full 80% discharge, and guaranteed for 1500 cycles in industrial use. Last week we removed the batteries from the keel sump aboard Beowulf and sent them back to Trojan for service. We used a combination of main halyard and boat yard hydro-crane to remove them. It is somewhat over five years ago now that we purchased these batteries, and they have sat around for the greater part of this time – not a good thing for their capacity. Trojan took them in, cycled them to the 80% level twice, and then did a voltage check. The check is done at the discharged resting voltage. Turns out that these batteries are at 105% of rated capacity. Not bad after all these years. In chatting with Mark Waycaster at Trojan about maintenance, he emphasized several things (which apply to traction batteries and their marine batteries like the L-16):

Unusual Revolving Storms

Firstly, let me say how much I am enjoying your books, Mariner’s Weather Handbook and Surviving the Storm. For anyone with the slightest interest in the weather around them and in taking a boat to sea, they are excellent reading. However, I do have a couple of queries:

On page 340 of the ‘Mariner’s Weather Handbook’ you show three photographs of tropical revolving storms, when and where they should not be, one off Angola (West Africa) in April 1991 and two of one storm in the Eastern Mediterranean in January (no year mentioned). It is my understanding that no tropical revolving storms have ever been reported in the South Atlantic (until now) and that the sea temperatures in the Eastern Mediterranean in January are certainly not high enough for cyclogenesis nor is the ITCZ anywhere near the Mediterranean. Have you any explanation for these phenomena and/or a year for the Mediterranean storm (I would like to research past meteorological records to find what conditions actually existed in the latter case).

I look forward to your reply, Brent

SailMail/SSB E-mail

When we first started cruising in the 70s a key factor in our desire to keep going was the ability to communicate with friends and family. In 1976 state-of-the-art communication was via an Atlas ham radio. One had to watch band conditions, and the voice connection was often difficult to hear. You’d connect to a shore-based ham station who’d “patch” you into his local phone system.

Solution for Ugly Vent Cowls

The most popular vent cowls are made by Vetus in a variety of sizes. These plastic cowls are light and functional. However, they have a problem with the sun – our experience is that after a very short period, sometimes less than six months, they begin to turn an ugly brown on top which progressively worsens. You can clean this off with acetone or MEK, but it returns quickly. In Marina Del Rey, where we used to keep BEOWULF, the Vetus cowls would turn brown within four weeks of cleaning.

We’ve found a solution. Nicro Ventilation Systems, Napa California, makes a white spray paint for coating vinyl plastic, and PVC surfaces – called “Nicro-Cote”. We purchased two cans from West Marine (their part #N28630) and used it o BEOWULF’s 13 Yogi sized Vetus cowls. They come up looking like new, and so far, six months after application, they are still looking good – much better in fact than the cowls looked at this point when new.

Vacuum Packers

We’ve been looking for a vacuum packer to use with dry and freezer stores (and spare parts) for some time now. One night while flipping channels we were tempted by units being sold on both the Home Shopping Channel and via an infomercial. We ordered a Tillia basic model for $120.00, which included several rolls of vacuum bags.

Chain and Rope Anchoring Combinations

Hi Steve & Linda, Thanks for the great Encyclopedia & library. We have been enjoying it for a long time now. Thanks also for your advice on the ROCNA anchor. We have now purchased one & hope to start using it & the boat soon. I’m wondering if you’ve any knowledge/feedback on leaded anchor line. We have 42 metres of chain but would like more. Unfortunately our anchor locker won’t take any more & I thought perhaps 50 metres of leaded anchor line might make a suitable compromise (added to the existing chain). We have not come across anyone who has used this product & are hoping you or one of your readers can help with some feedback. Thanks, Pam & Bill

Anchor Size – Flukes or Weight

Steve: You emphasize the importance of weight in anchors. Is it weight itself or fluke size that you think important? This issue has obvious relevance to buying a steel or aluminum version of an anchor where this is possible: Fortress and Spade. I don’t have an anchor windlass on my 40′ J120 and don’t want one. So I want a light anchor. I am considering a 33# aluminum Spade which is the same size as a 66# steel Spade. What do you think? – David

Keel

Hello Steve & Linda, I just watched Offshore, and enjoyed it very much. I have been looking around on your website, and I think it is fantastic. Well done. I dream of having a lifestyle like yours one day.

I’m 22, and have a 34′ custom riveted aluminum round bilge, Terhou, built in England in ’59. Within the next decade or so, intend to weld something bigger (and faster) for myself.

This goal has me thinking about design, best practices, etc. You mentioned in Offshore that Sundeer’s keel is welded on. How is the ballast installed? Is it poured inside? I assume it is lead? – Ryan

Hi Steve, You built some 74′ Motorsailors that are illustrated in the Cruising Encyclopedia, but not mentioned anywhere else that I can see. Can you tell us more about your Motorsailors. What are your current thoughts on Motorsailors? What IS a Motorsailor? BEOWULF is sometimes referred to as a Motorsailor and may be the best example of the breed. John T

Renovating an Aluminum Hull

I write seeking some advice on Aluminum boats. I have a 50 foot Ferru Pilothouse cutter. This French boat is constructed in Al but has epoxy fairing compound in varying thickness over the entire hull and deck (damn those Frenchies). The vessel was neglected for a couple of years so blisters formed over a large surface area. We’ve been chipping away at these blisters to allow air at the Al to prevent further surface deterioration and now the boat looks like it has leprosy. Inspired by your lithe bare-metal “Beowulf”, I want to remove the rest of the fairing compound to lighten the vessel and avoid the sisyphean task of regular paint and epoxy maintenance. The remaining coating, however are tenaciously adherent to the metal surface. These are some of the questions I have… 1. Is it advisable to strip the boat bare? 2. What is the best way to deal with the tiny areas of pitting corrosion that have occurred where water was trapped between the epoxy and the metal? 3. What is the best way to strip the epoxy from aluminum without damaging the hull and deck? 4. Does sandblasting have to be done with aluminum oxide grit or could another material be used? 5. Do you know anything about the French boatbuilder, Ferru? We love to sail our boat and we intend to keep her for many years. We are currently living aboard in New York. I would greatly appreciate any assistance.

Walnut Shells for Teak Floors

Greetings from the Florida Keys. Of all the great values one can find, your Offshore Cruising Encyclopedia is the best. We have used your book as a wonderful resource to guide our steps and now are the proud, and deliriously happy owners of a 45′ Columbia. An older boat, she is quite sound, needing only a lot of “elbow grease” and some electronics. We were fascinated by the application of ground walnut shells to teak saloon floors for a non-skid, good looking flooring (page 1034). Is there a supply source for the shells, or did you render them yourself? Thanks, Janine M.

Cruising on $30,000/year?

I’m retiring and thinking of sailing. I’m a Alaskan sailor all my life…but im thinking of US- VI or South Florida. I’ve fished all my life off boats that make so much noise you can’t think. A catamarn sounds like my kind of boat. What do you think? Can a guy figure on living free at $30,000 a year? I have no bills and no wife nor kids. At 56 it’s time to get a tan. Any commments? – Jim

Writing While Cruising

A few of your contributors mention writing articles as a source of periodic income while cruising. We have the option of submitting to some non-English periodicals and it seems to be a less saturated market. My question is, how much does one expect to get paid per article? If on contract to a specific publication, what is the nature of such a contract? If freelance, do you just send your article to a few publications and then wait (maybe months or years) to see if it gets published and they send you a check? Thanks, Aharon

Out-of-Print Marine Books

Hello. I was trying to purchase a copy of "The Ship’s Medicine Chest" that you recommend in the Offshore Cruising Encyclopedia (excellent book BTW!). However, it seems to be out of print. Do you happen to know if there is anything that replaces it or could you recommend something else or is it worth trying to get a used copy if it is not out-of-date? I do plan to purchase the other two medical books you referenced.

Repowering Lancer 42

I am in purchase inspection of a Lancer 42 sloop, engine Perkins 85 hp. Another same model would be far away and therefore about $25,000 more expensive to get with the biggest engine of 220hp. I am aware of hull speed formula, but these boats were build with planning hull and can speed up to 12 knots, I guess. Now, how could I change the power engine, do I need another prop and shaft, to become the most powerful and faster boat under power? If change, what are such costs and makes it sense, if the goal is to have just in case a fast boat? Thanks for your opinion, have a great day, Ute

Traction Battery Sources

Dear Mr. Dashew, I am a cruising sailor planning on taking delivery of a new Hylas 46 in June 03. I have been investigating traction battery options since reading your Tech Talk Battery Maintenance article on SetSail. In addition to the Trojan alternative source mentioned in your article, Yuassa and IBE also manufacture traction batteries. I am particularity interested in IBE as they are a “local” manufacturer to me and the boat will be commissioned in Long Beach. IBE batteries are about 40% less expensive than the source you recommended and they appear to have good life expectancy (1500 cycles @ 80%)and a 5/15 year warranty.

Since they have been available for many years, I wanted to know if you had had any experience with them and, if so, could share that experience with me. The 40% cost deferential saves me over $1200 on a 1000AH 12V bank so I would like to have additional info to make an informed decision. I look forward to your response. Best Regards, Phil

Hull Blisters / Rudder Type

Good afternoon Steve and Linda…Continuing to benefit from owning and referring to your fabulous Offshore Cruising Encyclopedia…A great investment and representative of hard work on your part…I also continue to work on buying that Jeanneau 34 I mentioned to you about a month ago by e-mail, and I saw her for the first time yesterday at her new home in New Bern where she has just arrived from being in the Caribbean for most of her seven years…She is up on the hard for now, which gave me the opportunity to see her hull below the waterline…There is noticeable blistering on both sides…Close to a dozen on each side…They are all the same size…About two inches diameter and all open and faired like somebody has already been working on them….Do you consider this type of hull blistering to be a significant fly in the ointment? I can’t find it now, but I recently read an article with the point of view that hull blistering is inevitable and is really not such a big deal…that the core fiberglass remains sound…Do you share this view? Would you say these existing blisters should be filled in? Also the rudder is not on a skeg, which is probably a strike against her would you say? Thanks mucho.

Columbia 50 Exhaust

Dear Steve and Linda, I own a Columbia 50 sailboat and I am redoing the exhaust system. Do you know what the original water jacket exhaust was made of ? I have been told that copper is the best as long as no other metals are involved. I have tried a water lift but the back pressure is taking too much power from the engine (Westerbeke 107). I would like to go back to the original as I have the room to do it now. A stand pipe would work but I do not like the long section of dry stack. Any information would be helpful. p.s. great books I have “The Circumnavigators’ Handbook” and “Offshore Cruising Encyclopedia” Thanks So Much, Charles

Weather Logic–BVI to Bermuda

Hi Steve, We were planning to leave for Bermuda tomorrow, but just received a WX report from Commanders that’s a bit scary. They are predicting the “largest storm of the season” over Bermuda this Thurs and Fri. Are suggesting we can get there before it hits, but I’m not sure about that. And even if we get in safely, will have to anchor in St. George’s sufficiently well to withstand 55 knots, according to them. We asked Herb about the storm tonight, but he refused to comment, saying Fri is too far off. I can’t see the warning signs on the 96hr 500mb (maybe they’re over the West Coast now?), but I confess I’m still not great at understanding the 500mb charts, your Mariner’s Weather Handbook notwithstanding. We have no deadlines, no pressure to leave, except for a fridge full of food! What do you think, O Great Seer of the 500mb charts? Commanders says if we don’t leave tomorrow, we should wait till Tuesday, and will be motoring most of the way. By the way, David Jones has not warned our friends about this at all (they’re using him for routing), and they’re expecting to arrive in Bermuda Thurs or Fri as well.

Sorry to trouble you, but I would appreciate your opinion. By the way, we’re in Virgin Gorda Yacht Harbor, and BEOWULF looks in great shape over there in the yard. Regards, Candace

Ridges and Troughs

I’m reading your excellent Mariner’s Weather Handbook. Thank you for a clearly written explanation of weather processes. I am confused on one important point however. In the sections starting with “Ridges and Troughs” (p. 127 +), if I understand correctly, a RIDGE occurs when the 500 mb pressure is at a higher elevation than the surrounding 500 Mb air and at the surface underneath the ridge is an area of LOW pressure. However, when I listen to the weather broadcasts (NOAA, weather radio, nightly TV news, the weather channel) they all refer to RIDGES of HIGH pressure! Did I miss something?–Steve

Luke Propellers / Murphy Gauges

I very much enjoyed your Encyclopedias, Volumes 1 and 2…Do you have an address for the manufacturer of the Paul Luke "Hyde" propellers? I have used several Barrett and Maxiprops over the years, and have found them to be VERY inefficient compared to a fixed pitch (like 2.5 knots worth) It always seemed to me that a feathering prop with a little twist would be the answer, but I didn’t know that they existed until I saw reference to it in your book. If it’s not too much problem, do you also have a source for your "Murphy" gauges?

I am now interested in a 40 foot Newporter that seems to be in great shape. I’m the guy from Alaska and wanted a motorsailer. Do you know anything about these boats? There was 122 made, an older model but appears to have nice lines to her. The only thing I might wonder about is the freeboard. She is nice and heavy at 30,000# 5600 in the keel. I happened to love wooden boats. This is a cold mold with fiber glass. I anxiously wait your response. Cheers, Spike

Deerfoot 58–Sundeer 60 Displacement/Racing Issues

Hi Steve, Thanks for the input on the SD 60. Ever set one up as a ketch? Also, somewhere in my readings of your work, I believe you stated that you calculated displacement differently than most boats so that an allowance for the typical load of stuff that offshore cruisers carry is in the total displacement figure for the boat. Does this mean that the figure usually given for most boats, say on a PHRF certificate, is not the same as the number for displacement for your designs? Also, what kind of ratings would your SD 60 or DF 58 get under the various handicap systems, not to be used to judge the boat but to see how I might fare in a race. Thanks for your help, Crawford

Dear Sir: On page 357 of Offshore Cruising is a picture of a 38′ Chuck Burns Design. I was wondering if you could tell me if this was a production boat or if it was a one-off. I love the Golden Gate 30/Farallon 29 and the Nor-West 33, but have found that both of these designs are too small. I have been hoping to find a larger Burns design and any help you could provide would be appreciated. Thank you, Jeff

Halyard Brake for Use with a Furling Boom

I am installing a small electric anchor winch to hoist and reef my boom furling main, which has a large roach. I would like to have a halyard brake or other device to maintain light, constant tension on the halyard as I haul the sail down to reef or stow completely. If tension varies, the roll loosens and risks jamming against the front of the boom. Who makes such devices, or can one find a rope clutch that has a variable setting that could be used? I don’t care what it is called, only that it does the job I require…Thanks….Lowell

Staysail Stay Made of Kevlar

Dear Mr. Dashew: November 2001 Sail magazine contains an article by naval architect Roger Marshall titled "Seamanship in High Winds" in which he states (page 36), “…I believe that every boat that is intending to go offshore should have a staysail stay, possibly made of aramid, on which to set the storm jib.” My question concerns the nature of such a staysail stay made of aramid. Could this be as simple as an aramid halyard attached to a folding padeye on deck made tight with a winch? (Assuming the geometry of the aramid halyard/staysail stay would be acceptable using the topping lift sheave, for example.) If so, such an arrangement might appeal to coastal cruisers such as myself, who would like to have the option of using a hanked-on storm jib on a staysail stay but have difficulty justifying a conventional staysail stay installation due to its low frequency or probability of use.

If my understanding, as set out above, of what Mr. Marshall intends is correct, how satisfactory would such an arrangement be in actual use? Do you believe this would be a good option for coastal cruisers such as myself? (I realize the scope of my question ignores additional important considerations like keeping the mast in column, possibly using running backstays or swept-back spreaders, etc. and the structural concerns of the deck handling the loads.) If such an installation is a reasonable approach, I am sure you can see the potential appeal for some cruisers. If one were lucky, installation might be as simple as installing a folding padeye on deck, replacing the topping lift with aramid line run to an appropriate winch (assuming the topping lift sheave is located opposite upper swept back spreaders) and buying a storm jib with hanks. Wishful thinking? As always, thank you for your assistance.—Downing Mears

Ketch for Bruce Roberts 38

Dear Mr. Dashew, Your books are most informative, thank you for writing them. I have recently inherited a steel Bruce Roberts 38 built by an uncle who was a professional fitter/welder. I like the boat, but do not favor its ketch rig. Reading your work, it has occurred to me that I might convert the rig to a mast forward sloop.

At the present time I do not want to replace the entire rig. However, in preparation for a 6 month Bahamas–Chesapeake cruise I need to replace the main and one headsail anyway.

So, here is my question. Am I likely to benefit from removing the mizzen and replacing the main with a much larger big roach full batten sail, keeping the current mast in its present position (13ft from bow, LOD 38)?

Knowledgeable friends tell me that there are many complex balance and stability factors involved. I question this because I can balance the boat without the mizzen on most points of sail over a fairly wide range of wind speed. As for stability, I would not increase mast height. With a P36ft/E14ft I can almost match the sail area if I go with a big roach mainsail.

I contacted Bruce Roberts but was dissatisfied with the response as they only wanted to sell me plans for a traditional cutter rig.

If the conversion has merit can a good rigger/sailmaker help me work out the details or would I need to involve a naval architect? Any recommendations? I’m in Florida. Thanks, Beau

Furling Mains

I am currently looking at a 54 Hylas to be used for coastal cruising in Florida and the Bahamas, very little extended blue water. A lot of daysailing. Would you recommend a furling boom or in-mast (vertical battens)? Are the in-boom furlers relatively trouble-free? Thank you. Richard

Rigging Drogues

Aloha Folks: I am, like too many new cruisers, spending money adding things I MIGHT need…I am thinking about prep for the day at sea when not smart enough to avoid heavy weather, and I need a drogue.

AVALON, TPI hull #5 has at the stern port and starb an open chalk on the rail thru which in a tie up to a dock leads fair to the cleat mounted thwartship on the stern.

I am wondering how to secure drogue lines considering their strain and the stern line cleat set at right angles to the pull of the drogue line.

What would you say to leading the drogue bridle thru the hole between the cleat “feet”, then a single turn around a heavy winch then secured to the midship cleat on the rail? The winch turn to facilitate retrieval, the stern cleat to provide a fairlead, and the midship cleat to provide a fair securing place.

Thanks, Scott

Using Drogues When Crossing a Bar

Re: your article in Cruising World some editions ago concerning crossing a harbour bar. As a last advice there could be the option of using a drogue from the stern for stabilizing reasons (I also use a drogue as a steering device).

Multihulls in Heavy Weather

Hello! The subject of Multihulls vs. Monohulls is a hot one, and is likely to continue to be. 🙂 However, there is one designer who has put online a very good paper on multihull seaworthiness. It is, of course, true that he is a catamaran designer, so the criticism may be the paper is biased, but it is very technical in nature, and I find (having an engineering background) reasonably complete and suited to the informed lay reader.

The article on your site I am referring to is: Multihulls.

John Shuttleworth’s article on multihull seaworthiness is here: http://www.steamradio.com/JSYD/Articles/NESTalk.html

I believe that your opinions may be swayed by his treatment. As always, seaworthiness is as much a function of the crew as of the boat, but a good crew with a bad boat can only go so far. I was very timid about the idea of multihulls and blue water, but decided I would research it before making up my mind. What I found were many good sources of experience reports (MultiHull Voyaging by Thomas Firth Jones for example) which finally convinced me that multihulls, designed correctly, could be as seaworthy in blue water as a well designed monohull, if not more so.

I have heard a bit about storm tactics and multihulls, and the one thing I have heard that I do not know if you have mentioned (not having purchased your book yet) is using a large para sea anchor. I am told that using a very large para anchor, head-to the seas, creates a slick much like the one one gets with a keel boat that is properly hove-to. The idea is to use the para anchor at roughly a one wavelength distance from the boat. This saps the waves power as it comes towards the boat and will then rarely, if ever, break across the bow. Since swell cannot capsize a boat, it stands to reason that this would be a very good tactic.. a sort of heaving-to for a multihull. The para anchor should be something like at least 75% of the beam. I have heard that 28 foot, nylon para anchors are most common, being able to be gotten from other sources than custom. Have you heard of this tactic?—Timothy

Roller-Furling Mains and Center-Cockpit Boats

1) What are your thoughts on the merits of roller-furling mains, especially the leisure furl boom systems which allow a better cut main with full battens?

2) Center-cockpit boats–Is the benefit of a better aft cabin and a small afterdeck worth the wetter, more motion at the helm that results from being higher up and more forward?

Snuffer

I’m about to order a gennaker for my Sabre 402 and have been trying to decide between your snuffer and ATN’s. For dousing, ATN recommends blowing the tack before pulling the snuffer down. If I am reading your response to Doug Peters’s question about this, you seem to be recommending easing the sheet. Having had some difficulty doing this with the non-ATN, non-North snuffer on my last boat, ATN’s idea seems sensible to me. Is there a reason I couldn’t take this approach with your snuffer?

Tips for Electric Windlass

Dear Steve and Linda, Impressed by your books, esp. the encyclopedia. Still I’ve 1 question: I’m looking for a powered windlass for my new 50′ ALU ketch. In your books you hint electrical windlasses are good enough, however I hear from different people that they can only work for a short period because of heating of the DC motor. Indeed e.g. Muir says to me: max. 10 minutes running time. At a speed of 8 m.min that’s only 80 meters chain. Now you also write that anchoring involves 3 maybe even 5 trials before the anchor holds. How does that relate to each other? Wouldn’t therefore a hydraulic windlass be better? Many thanks in advance, Ronald

Building Trawler in China

Good Morning Steve: I have a 98 Valiant 42. I’m selling her and moving to the trawler mode. Most trawlers are just ugly–too high off the water, too much windage. I’ve found the Dieselducks designed by George Buehler and built at Seahorse Marine in China. Please look over these and let me know what you think. Here is their website: http://www.seahorseyachts.com/ Go to the dieselduck 44 and take a look at them. Please let me know how you feel about steel boats and if the design is sound. I respect your opinion more than anyone out there. Thanks again, Roy

Centerboards

Dear Steve and Linda, heaving read all of your books I would like to thank you for your advice given there. As only one example, we’ve changed our mainsail to an extra-roached, fully-battened one which gave us 1 knot extra speed at all courses, which is a lot for 34 feet. Having a double backstay we don’t see any problems even with 30 cms overlap.

My question now is: What do you think of centerboards? We are interested in a 43′ Dutch aluminium Koopmans design which has no keel whatsoever. She sports only internal ballast and the centerboard seems rather small (weighing around 400 kg). The boat was constructed for falling dry in the North Sea. She has a long waterline and a draft of 1,20 meters board up and 2,50 m board down. The rudder is fully integrated into the hull and in line with the ship’s bottom, more just like a motorboat. Is the rudder surface of approx. 1,2 squaremeters large enough and the profile (not balanced) effective to steer the ship in a heavy going?

Thanks for some advice, and have some fun with your grandbaby. Andreas

Stern Tubes in Steel Boats

Dear Steve & Linda: Received your Offshore Cruising Encyclopedia Second Edition for Christmas 97 and I cannot stop reading it. I am at present building a 45ft steel motorsailor from a kit. The design includes welding a steel tube into the hull for the propeller shaft stern gear. As this tube is bored each end to accept the cutlass bearings and salt water is pumped through to lubricate these bearings, I am concerned about rusting of the inside of the tube and the corrosion around the cutlass bearing making for difficulty in removing for replacement bearing. Is it possible to manufacture the stern tube from stainless steel and weld the stainless to the steel hull? This would give the protection from corrosion. If it is (possible), what would be the ideal grade stainless steel? The propellor shaft is 316 grade. Regards, Dave

SSB Groundplane

Hello Dashews: We have a Cal 2-46 and I am struggling with how to build a substantial grounding plane for the SSB–the previous owner did not have an adequate installation. Could you give us some suggestions? So far, we understand that the sintered bronze plates are not adequate. One person suggested that we cover the entire rudder in copper plate, two have suggested that we epoxy copper screen into wherever we can in the bilge (which would be a lot of relatively small pieces), someone suggested multiple copper strips running lengthwise in the bilge and Ed at American Marine Coatings in Seattle says he can mix up a batch of his product with sufficient copper in it to make it conductive so it will work if painted into bilge spaces and connected up. What to you think? Thank you very much. Jim and Leslee

Teledyne Vs. Webasto Hot Water Heaters

Hello, Because I am changing the interior of my wooden Van de Stadt Pacific sailing vessel I have to make several choices. Therefore I am happy with the Offshore Cruising Encyclopedia because it is based on experience and that is what I need. It is my intention to install a hot water heating system and in the encyclopedia is mentioned a Teledyne system what would be a better system in comparison with Webasto, which I know well. Is it possible to send me an e-mail adress from Teledyne because I like to know more about the system.I was not succesful in finding Teledyne on the internet, and I am sure you can help me. Thank you very much in advance. Greetings, Paul

Lathe on Board?

Good afternoon. This may be totally off the wall. But, would there be much of a use for a small metal lathe in a cruising situation? For making spare parts for my boat or better yet, making parts for other boats and getting paid for it? Thanks for any insight you will provide. David

Dinghy Storage

Hello Steve and Linda: As part of the crew aboard a Deerfoot 61, I will be assisting with preparing the vessel for extended cruising. She has a sugar scoop stern which brings her to 63′. My question is where to store the 12′ inflatable dingy. Currently it is hauled out of the forepeak, assembled, inflated and swung over the side using a halyard. The thought of performing this evolution at each anchorage is unappealing. After spending 6 years cruising aboard my own vessel which was equipped with davits I was mindful of the need to launch and retrieve the dingy easily. If we were sailing in protected waters the dingy with outboard hung in the davits. In open waters we removed the motor to the stern rail and snug the dingy up tight. Going to sea the dingy was brought to the foredeck, partially deflated, inverted and lashed down. I have looked over this web site and your book (an older one) and found references to the dingy but not to storage aboard the Deerfoot. Any references or insights would be greatly appreciated. Sincerely, Don

Flags of Convenience

Hi Steve, I’ve finally finished reading your Offshore Cruising Encyclopedia and look forward to Surviving the Storm. Great job on its contents and construction–first class! May I pick your brain on the pros and cons of foreign flag vs. US documentation…I am mainly concerned with trouble in foreign ports (both ways; foreign flag ownership issues with customs, and anti-US sentimental issues with the locals of US registered entities). Thanks, Bill

Diesel in the Bilge

Please can you help. We are new to boating and have a 40ft sailboat – recently the fuel tank was overfilled and as a result a valve in the gage popped and allowed a considerable amt of fuel into the bilge. I had just cleaned, polished etc the entire inside of the boat to make it smell OK after being closed up for some time and now it smells like the inside of a diesel tank!! Do you have any suggestion what we can do to help eliminate the smell – we are at Hastings, Victoria Australia and everyone here says we just have to live with it and it will diminish in time – I want to try anything – I get sea sick. Your comments will be appreciated. Thanks Bev

Awnings without Halyards

Good Day: We are sailing our 48′ ketch up the Hudson into Canada this summer. We keep the boat in Elbow Cay in the Bahamas and plan to pull the masts in Albany.

I’ve seen awnings that don’t need to be supported by halyards. I’ve seen them supported with frames made with PVC pipe. Any idea who sells or might have plans for such an awning?

Do you sell or are you aware of any videos that might be of interest to us for this trip? Kindest regards, Steve

Manual Engine Shut Down System

I am a Marine Surveyor in Northern CA and I am in the middle of managing a large maintenance and upgrade project for a client. The client is interested in following a number of suggestions made the the “Offshore Cruising Encyclopedia”, one of which is having both an electric and manual shutdown for his diesel engine. The local Yards are saying they’ve never heard of doing this and I was wondering how to contact Steve Dashew to see if there is a drawing or write-up explaining the linkage so that we can move this process along. I have no doubt I can “engineer” the idea but was trying to avoid “re-inventing the wheel”. Can you provide me with his e-mail address or an address of someone who might have this info? Thank you, Michael

Troughs / Typical Storm Tracks

Steve…I hope you will forgive me for taking advantage of my ability to contact you so easily to clarify two points mentioned in your book. I realize you are extremely busy and would understand if your response came after you have completed your new book. Firstly, if I understand correctly, troughs (areas of lower contours) shown on the 500 mb charts are actually areas of higher pressure (page 136 of Mariner’s Weather Handbook).

Gulfstars for Cruising

Another question to add to “The Right Boat” category, if you have a moment. I would certainly appreciate a comment or two regarding Gulfstars as a sailing boat, specifically the cutter-rigged Gulfstar 44. Anticipated use would be primarily coastal cruising and island-hopping in the Caribbean.

Survey for Used Cal 40

Hi Dashews–After many months of research and viewing, we have found our first boat! We are buying a 1964 Cal 40 in mostly lovely condition for about 50K. I would like your opinion on a couple of concerns I had about the boat.

1. We had an engine survey done and the V-drive needs replacing–what other mechanical systems would V-drive failure affect? Stuffing box? Prop? etc?

2. I have been trying to find out specifics on the hull construction (I was told it was made of 5 hand-laid layers of fiberglass & would be thrilled to find out if that’s true!) but am not having much luck. Are there any non-destructive tests that can be done on hulls to check the condition & thickness of the fiberglass?

3. I have done enough research to know that the tabbing on the Cal 40s is weak and that there are some concerns with the deck-hull joint. Will a surveyor specifically check the bulkheads and the d-h joint for signs of weakness as a matter of course or do I need to instruct him as to what exactly I want inspected?

4. There is some minor decay on the bridge beam–what’s the best way to stop it? Any info at all would be appreciated–we set sail for the first time ever in June!! Thanks, Erin

MacGregor 65’s

Hello Steve, I am sure you will know this design as it is not unlike yours. In your opinion is this a good boat to go cruising in? What do think are its good points and bad? I am concerned that it is very narrow and may not be a stiff boat. Also is the quality and strength of construction sufficient for blue water cruising. Thanks for any help you can give me.

Swept Back Spreaders and Baby Stays

Dear Steve, We have been following your commentary for years now and have a question that we hope you can help with.

Do you feel that a baby stay on the ketch rigged Sundeer 64’s would aid in preventing a mast inversion due to operator error? What conditions would create a circumstance where you could lose the spar?

I am referring to page 662 of Offshore Cruising Encyclopedia, regarding your discussion of swept back spreaders. Is this setup less forgiving than a conventional spreader configuration with forward shrouds?

Any comment would be appreciated. Thanks, Wayne

Mainsail Track Systems

Hi Steve and Linda: You may remember me as a contributor Surviving the Storm (RAMTHA Photos). We have purchased a Gitana 43 IOR-type yacht in order to undertake our planned extended cruise to the Northern Hemisphere starting 2004. The yacht is well proven with 5 Atlantic crossings and South Pacific passages since she was launched in Cape Town in 1981. We are now planning her refit. We intend unstepping the aluminium mast and closely inspecting the rig. This raises several questions as to how much we upgrade the mast systems and we would value your comments.

We intend keeping the slab reefing system but see potential in a low friction track system with Bat Cars. The mast currently has the original track where the slugs are flat and slide inside a track that is riveted on to the mast. The same system used for most trysails. The question is: Is there any major advantage or gain in upgrading to a low-friction track system with batten cars or should we continue with the existing system and be happy with the fact that the last third of the main needs to be hauled down by hand? The reefing is done at the mast. We intend adding lazy jacks and like the look of boom bags instead of a standard sail cover. Regards, Lindsay and Lynley Turvey

Catamaran Rig Options

I recently read an article from Forespar, showing that your 78 foot Beowulf is using their AeroRigging spars. My question to you is, does this set up support less maintenance, ease of sailing? Also, I am very close to ordering a 46′ Prout Catamaran, and I am considering my custom rigging options. Which way would you go: Carbon Fibre Spars and Poles AeroRig Furlaway E-Z Furl? I will primarily be the only sailor aboard. Would you please share some of your tried and true experiences with me regarding the way you would go in this situation? Rory

UHMW Chafe Panels on Jib

Hi Steve, I note in your latest book thay you suggest using 2 mm UHMW for chafe patches. I have a Kelly Peterson 46 and am having my sacrificial jib panel replaced. I want to redo the spreader chafe patches as well but my sail maker doesn’t know where to get the UHMW material. He is game to try this, but thought if he can’t find it, maybe heavy (40 mil) dodger window material would work well. Any thoughts where to get the UHMW or does the dodger window material sound good? Thanks, Carl

Hydraulic Steering for 65′ Steel Motorsailor

Hi, My wife and I are looking at buying a 65′ steel hull motorsailor that is not finished. By that I mean all that’s there is a complete hull with two engine rooms. If we buy we will most likely put in Perkins 135 hp engines as that is the design called for. My question today is about steering. The boat weighs at full load 96000 lbs. The rudder is a big one – 16’x14’x6′ and weighs 500 lbs. I know very little about hydraulic steering but that seems to be what most of the shipyard managers whom I’ve talked to suggest. Which make would you recommend as being able to add to it, if and when the situation arises? And which has a back-up in case of power loss? Or which could work on batteries vs engine power? And where can I find this information written down (on the page or the web)? Thanks, Rod and Lucy
