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

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.

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.

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.

Anchor Chain Storage

I am doing an extensive refit of an old Pearson Coaster (30ft) with the goal of doing some extensive cruising. One problem I have been attempting to solve is the storage of the anchor chain. I know were I want to store it, in the keel, but getting it there is the problem.

I want to deliver the chain to the keel from the windless through a PVC pipe to the keel. My theory is that the PVC pipe is something that should be considered a wear item. I would be installing it in such a way that it can be easily replaced. Thus far I have isolated that I need a minimum slope of 12 degrees and that I need to use a pipe size of 1 1/2″ ID for the 1/4″ High Test chain. The next size smaller PVC pipe, 1 1/4″ ID, is just the right size that if a link rolls up the chain will jam.

This appears to me as though I might be going about this from the wrong direction. I don’t have any experience in this area and something doesn’t feel right about my solution.

If anyone has had any experience in this area and would be willing to share any suggestions, they would be most welcome. If I am going about this from the wrong direction, please tell me, and if there is a better way to approach this problem, that I would also like to know. Thank you in advance, Fred C.

Tread Plate vs. Nonskid?

Dear Steve and Linda: I am following you book as a guide (maybe I should say Bible, as I suspect many others are also). I plan to use a lightweight tread plate on the walkways on the top of the hulls and a few other places. The builder is concerned that, when the tread gets wet, it will be quite slippery. He thinks that you must be putting something in the way of nonskid on the tread plate. I suspect he is wrong but thought I should check. He is recommending that I use normal aluminum decking and apply a cork-based product made in Great Britain [I believe]. I prefer to stay with the tread plate, but only if this going to give me good footing when wet. I would appreciate knowing your experiences with the tread plate decking, as far as being slippery when wet. Incidentally, you recommended that I go with 80 grit versus the 120 I had considered. Boy, were you right! It looks much better. I am going to use the Barnacle System, I think, and thought of finishing the bottom in 120 grit and running without bottom paint to see what happens with just the Barnaclean system. [Your thoughts?] -Bill

Glacier Bay Fridge System

Dear Steve and Linda, I have refitted our 60′ cutter with Glacier Bay refrigeration (DC Whisper Jet, 24v). We also added an 8000 BTU and 16000 BTU air-cond unit forwd and aft. This system has been very tempermental. We are on our third compressor. Leak testing is a nightmare. We have an excellent technician on this install and we have now borne the additional expenses of several faulty components having to be traced out and replaced, each time with the added cost of pulling a new vacuum and recharge with 134. We have followed the manual and Glacier Bay’s instructions to the letter. Among the problems we discovered is a great variation in the amp loads between the fridge, freezer and ac. We are about to give up. I heard from a Florida broker that you had tried this system and went another direction. Do you know someone with a wealth of knowledge about this system? Glacier Bay does not seem to have any solution. It was only after we installed our system that Glacier Bay came out with amp hour recommendations. Our system cannot even perform well with a constant AC source from dock power feeding the battery charger (we installed a new "smart" VMI 24v charger. Another issue is that the battery charger keeps a constant voltage of 27.6 to the Glacier Bay system, while the Balmar alternator runs willy nilly up and down the scale, depending on engine rpm. Would a voltage regulator help this situation? We boiled the electrolyte out of the fridge/frzer 24v bank while motorsailing. Sorry for this barrage of issues. I would appreciate any suggestion. Thanks, Wayne

Finding Crewing Position

Hello SetSail folks…

First things…I have truly enjoyed your website and cover stories, please continue with your efforts. I am writing from Edmonton, Canada in hopes of receiving some direction or recommendations from those with much more knowledge in the area of sailing than I. I understand my vision may be a long-shot, but am hoping someone will come to my aid.

I have enjoyed the opportunity to be a passenger on a few larger sailing vessels (cruise-like atmosphere) in the Caribbean and am now looking to expand my travels, feed my desires and drive for sailing and partake on a short or long-distance sailing venture on a smaller vessel. Unfortunately, my skills in the same are lacking, as I have no formal or informal training here. I have a reputable and successful career in health care, but am looking to leave and do some traveling, particularly to join a family or crew on an extended sailing journey (s), to offer my assistance if/where possible and perhaps learn about seamanship during the ventures. I am considering travel in the Caribbean, Australia or other tropical destinations.

I again realize this may be a long-shot and was at a loss as to where to initiate such a search. Can you offer any suggestions, contacts or links to families or individuals in search of a trustworthy, hardworking and dedicated traveling companion for their travels (this could also include for child care, extreme novice crew, or even bartending)? For personal information on myself, I would be happy to offer that which would help narrow the search. For the basics, I am 30 yrs of age, female, divorced and financially secure. What else can I offer to assist in my search? Please let me know of any suggestions. Your help is greatly appreciated. Do not hesitate to contact me via e-mail. Thank you, again. Tammy

Foreign Flag Registration (revisited)

We are a family of 2 adults and four (soon to be five!) children about to embark on full-time cruising. We have ordered the Mariner’s Weather Handbook + CD and eagerly await its arrival.

In the meantime we have a burning question for which we cannot seem to find a clear answer. If the answer is in your Encyclopedia, just point us in that direction. We do plan to buy it, but are trying to pace ourselves on literature since one can only read so much at once. Anyway…

We are refitting an old Royal National Lifeboat here in England. We cannot register it here (unless we incorporate in the UK for the purpose) since we are not British citizens.

Our choices seem to be US Registration, or registration in the Grand Cayman Islands or some other offshore entity. Do you have any thoughts on the pros and cons of registering in various places? So far all we have found is a brief reference in “Voyaging Under Power” stating that really official US Registration papers can be helpful.

What do you think? Thanks, Russ & Karla & Crew

Frigoboat Keel Cooler Refrigeration

Steve, I’ve been sailing over 67 years. I sail a 1973 Pearson 33. I’m on the verge of installing a Frigoboat Keel Cooler system, which, as you no doubt know, runs the refrigerant tube thru a shoe outside the hull for cooling. However, I have concerns about corrosion and marine fouling, as the shoe cannot be painted. The salesperson that I’m dealing with said (his spelling): "Sailing gurus Nigel Calder, Tom Neal, and Steve Dashew all use and endorse the keel cooler." Tom Neale is not familiar with it and I haven’t yet reached Nigel Calder. Do you have a track record with the keel cooler? Sincerely, from the Jersey Shore, George

Dual DC Alternators

I’ve got an electrical generating concept to bounce off you. The boat is a catamaran with two Yanmar 27 HP engines. I want to power a Marine Air 16K btu air conditioner without adding a genset (third engine, weight). I’d like to run two 120 amp alternators in parallel on each engine (one regulator per engine) by connecting their fields together. Then add a second 3KW inverter that powers only the airco compressor. A link 20 runs the 800 AH battery bank. What do you think? Thanks, Bill

Weather Windows

I am hoping to make this trip starting in October of this year. Do you have an opinion regarding the “weather window” in mid October? From what I have read I should be OK although there are always exceptions. I thought I would keep an eye on the group of people in the Baja Ha Ha race that usually head south from San Diego to Cabo in late October. If there are no storms developing off the coast of Mexico that would eventually head northwest then I thought I would leave San Diego on a rhumb line for the “Islands.” If you have an opinion or experiences contrary to mine, I would appreciate the input. Sincere and personal regards, Jim Alexander

Wind Shear

Hi Steve and Linda, I just started reading your Mariner’s Weather Handbook and I stumbled across something on page 59. In the italic at the bottom of the page it is stated that the effect of coriolis is less at higher altitude. I was puzzled by this, because from my time as an aviation student (a long, long, 21 years ago) I remembered that, due to friction, the effect of coriolis close to the surface, and especially over land, was less. Also in the italic part you (correctly I believe) state that over water (less friction) the wind angle relative to the isobars is less. This indicated a greater effect of coriolis. With no coriolis at all the wind angle would be perpendicular to the isobars. This also agrees with my experience as a pilot. The first 4000ft or so the wind veers as you go up. Less friction means greater effect from coriolis. What do you think? Has 21 years been too long or is there indeed something unclear in the text, and is it that what has got me thinking? I would very much appreciate it if you could shed some light on this matter. In the meantime I’ll continue reading your fine book, as I’ve done with the Offshore Cruising Encyclopedia.

Hundested Prop

Dear Steve,

I am building a Bruce Roberts kit of 54′ radius chine cutter. After reading the Offshore Cruising Encyclopedia and viewing your Beowulf: The Legend DVD, I have decided to install CP prop by Hundested. I am getting the prop from Todd Terry at Pacific Marine Equipment, Inc. in Seattle. As far as I was able to find out, they are the (US) West Coast distributor for Hundested gear. Anyway, the thing is: You are saying in your book that you were using VP2 model, which according to Todd is no longer available. Therefore I am going with a bit larger VP3 model. Now, according to Todd, one can choose either fully reversible pitch prop or fully featherable prop to minimize the drag while sailing.

If I choose fully featherable prop, my reverse pitch is very minimal, nowhere near the forward pitch. If I choose the fully reversible prop I will have to give up the low drag feature of fully feathered prop.

After viewing Beowulf DVD In the chapter titled "Maneuvering Under Power", you have Linda reverse the pitch from 3.5 ahead to 4 astern. The scale on the gauge shows up to 6 ahead, up to 5 astern and also feathered position. Does it mean that with the VP2 you had the option of having nearly fully reversible pitch and also feathered position for sailing???

Are you familiar with the VP3 model and what is the difference between it and the old VP2 one? I have seen the operational model of VP3 in Seattle and in fact the reverse pitch is very minimal, a fraction of the forward pitch capabilities. Was your prop the same way?

I am sorry for rumbling on and on about it, but the Hundested props as you know are not cheap and I would like to make sure that my money will be wisely spent. I would be very grateful for your comments regarding this matter.

Good luck with your UnSailboat! I hope to meet you one day in some anchorage. Best Regards, Remek

Ex-Whitbread Racer for Cruisings

I am considering the purchase of a 63′ vessel which is located in Rhode Island (I happen to live in Portland, Oregon). I am including a link to the broker’s listing for her and, if you have a moment, would appreciate your thoughts. The owner says he has been aboard BEOWULF, so you may have seen his boat, also.

Any thoughts or comments will be appreciated. What I’m looking for is a boat two people can sail. This one would take some work to get there, but it seems like it could be possible…

I have become somewhat obsessed with her, but am not sure it would be in my best interest to get involved. She seems like a once-in-a-lifetime opportunity…Built to a high standard, to withstand sailing in the Southern Ocean. Fast, lots of interior room to setup for live-aboard. The structural advantages of aluminum.

I’m looking for honest, direct thoughts.

Baby Stay Downwind

Hi Steve: Question: I have a double spreader rig on a Beneteau First 375. Gybing downwind with the babystay means you have to remove the pole from the mast toggle and move it around the other side of the babystay to complete the gybe (somewhat of a pain). Do I need the baby stay downwind? Can’t I loosen it off so it could be bungied back to the mast and then do a dip pole gybe using tweakers, with two sets of sheets and guys? It seems that would be easier shorthanded, Thanks again, Gord

Rigging Costs

My husband and I are in the process of buying our first boat ever. We plan to live aboard while we learn to sail. I found a 1972 Challenger 40 for $29,000. It has a 13’10” beam and is really well laid out–we’d be quite comfortable living in it. However, it needs all of the rigging replaced. We just read an article in Cruising World about the costs of refitting a boat which gave a rigging replacement estimate of $10,000. In your opinion, do you think this would be worth it? We don’t mind investing elbow grease and gear costs, but we also don’t want to “go down with the ship” on this! Thank you! Erin

Maxi Roach Mains / Roller-Furling Booms

Dear Mr. Dashew: I have been using a roach/leech overlap of 20% with no problem of backstay passage, and I have found this conservative, and have had no chafing problem over a six- or seven-year period. Have you used higher percentage overlaps successfully?

I am currently considering the use of a single diagonal batten just down from the head of the sail to get the leech well out, and then downward, with the battens having up to a 50% overlap. By that I mean that if the distance from luff to backstay is one meter, the batten would be 1.5 meters long.

Watching videos of my sail passing the backstay in slow motion plus years of experience show me that the sail “peels” across the backstay from bottom to top. Therefore, once the sail assumes a rounded shape, the battens slide easily across the backstay. Do you think 50% overlap will work, and is this a maximum?

A final question: Have you used roller booms on any of your boats? I am using a roller boom, and this raises some additional issues in the event you have experience or thoughts on maxiroach sails and roller booms. Thanks in advance for your comments. Lowell

Rudder Design and Steering Problem

Steve at SetSail, I’ve experienced significant weather helm sailing my 50′ custom design cruising catamaran in winds 12-15+ knots. When entering an inlet in confused tidal currents, the helm is heavy and the vessel slow to respond under power. A growing concern among my designer, sailmaker, rigger and a couple of experienced sailors who’ve been aboard is that the rudders are undersized and/or unbalanced. Can you recommend any source(s) to help me understand more about rudder design and performance? Kind regards, Jim

Range of Stability for Early IOR boat

After reading your Offshore Cruising Encyclopedia I have a couple of questions about converting an alum. IOR boat to a cruiser. The boat, Doug Peterson 44′ alum. flush deck, displ 25,000 keel 10,000 , 13’6″ beam 8′ draft. Built 1978. Intended uses of boat, Mexico and South Pacific.

Should I be concerned about the range of stability? If I buy this boat I plan on adding extra tankage low in the hull and under the floorboards if possible.

Is there a formula to figure range of stability ?

And lastly, I really like the 14′ Wherry pulling dingy. Are they still in production?

Hi I am having trouble getting an answer on how to reef my main sail. I have a Beneteau 350 Oceanis. It is “new to me” but the person I purchased it from could not reef the main. It is a North sail. I will try to describe what I have. First of all the Sail is set up for Dutchman flaking. (I don’t think this has any bearing on the problem) This is applicable to both the first and second reef points. The main sail has only 2 cringles.

I have a line that starts at the cockpit and goes to a pulley at the base of the mast. From this point it goes up to a pulley into the mast end of the Boom. It exits the boom at the clew and goes through the cringle in the sail and then the bitter end is made fast at and anchor point at the bottom of the boom.

As it is currently rigged I can reef the back of the sail. I cannot reef the luff or front. There must be some way of leading the line through he cringle at the luff of the sail. I can’t go from the base of the mast to the cringle because when I return to the boom it would be on the wrong side of the pulley. I am sure it would snag.

I do have 2 open stainless loops attached to each side of the mast but they do not seem to be at the right location to aid in the change of direction. I hope my description is adequate. Any help would be greatly appreciated.

System Seven Chainwheels

I am going to school on your experience. I am wanting to upgrade my windlass from an older AnchorMan that is better suited to line than the System 7 3/8th chain and 65-pound spade we have acquired.

I was intrigued by Maxwell’s offerings but their specs shown on the web seemed to indicate they support 3/8th SHORT chain? Have I missed something? The G-7 seems to have a diameter = .394", inside length = 1.23", inside width = .62".

Do you get a different chainwheel/gypsy? I saw a discounted Maxwell VW series 1200, but with a shorter chainweel/gypsy at my local chandlery that I would like to buy if it’s possible to get a chainwheel put in for the system 7 3/8th chain.

Snubbers for Chain Rode

Does it make a difference where on the rode you attach a nylon snubber when anchoring? I would think that closest to the boat would be best – putting the snubber between most of the chain shock and the boat, but that would make it impossible to shorten your scope after setting the anchor. Suggestions? Mark L.

Pilot House – Abrasion-Resistant Polycarb

Dear Setsail, I’m in the process of speccing out the glazing for the pilothouse on the boat I am building. I have narrowed it down to either 1/2" tempered glass or 1/2" abrasion resistant polycarbonate and am now looking for a little real world experience to tip the scale. One nagging doubt: the long-term durability of this product in the voyaging environment. I’ve read in your Offshore Cruising Encyclopedia that you recommended and used polycarbonate on your sailing vessels, but noticed that you made the switch to glass in the FPB series. After walking the docks at the boat shows and talking to designers and builders of some of the high-end custom pilothouse and raised saloon boats, it seems they all are going with toughened glass, but none seem to have any direct experience with abrasion resistant polycarbonate. What’s your experience? Best regards, Collin

Fiberglass Hull–Aluminum Deck

Hello Steve, I have been offered a really nice bare hull, but the mould for the deck is a center cockpit. I would like to build the boat as an aft cockpit. I could either build a deck in plywood and glass it on top afterward, but I wondered if I could build a deck in aluminum. This seems to me to be quite a good mix. Fiberglass below and aluminum above. This would suit me because I could leave it bare for non slip on the side decks and also I could build the hard dodger in aluminum. Do you think that the differential expansion between fiberglass on aluminum could cause a problem? I also wonder whether it might cause problems later with resale because it is so unconventional. Any comments would be welcome. Thanks, Howard

Treatment of Bare Aluminum Decks

Dear Steve and Linda: In addition to the above I also have both (editions) of your Encyclopedias. I am using the latest Encyclopedia as a guide, as we design a 65 x 32 aluminum catamaran, which will draw two feet when fully loaded. It is being designed by Grant Robinson in St. Augustine, Florida. It is to be built by Topper Hermason of Amelia Island, Florida. Your Encyclopedia has been more than invaluable and so I bought it for Grant to serve as a basis to make sure we are clear on what we are discussing. Based on your writings, I am going to leave the vessel unpainted and ground to 120 grit. I plan to spend years in the Southwestern Pacific. I am very concerned about what deck temperatures I should expect with unpainted deck and hulls in the tropics. I know you are very experienced in this area and would appreciate your input. Do the decks get too hot for comfort? Are you still happy with an unpainted aluminum vessel? What temperature ranges should I expect the deck to reach given being in the tropics and on open seas? I do appreciate your taking time to respond to the above. I look forward to your next book, which I understand will be available within a short time. Sincerely, Bill

SGC Radios

Dear Steve: I have just read your article in Practical Sailor’s latest issue regarding gear info after 38000 miles. In it you said you had a problem with your SGC 2000 HF radio and the Pactor II modem in trying to send e-mail. I own a 2 year old SGC 2000 with the new “Powertalk” remote head which I bought because it was supposed to be better for clear data transmission in poor conditions. You stated that the radio drifted off frequency (which obviously would mess up data transmission). Is this a problem with all models of SGC 2000 radios or a problem specific to your radio and/or model? I am just getting ready to purchase a Pactor II modem and get my radio set up for e-mail as my wife and I are preparing for a 2 year cruise on our Saga 43 from Maine to the Caribbean and then to the Azores and the Med. This problem with the SGC 2000 concerns me!! Should I sell it and get an ICOM 710 like everyone else?! Thanks for your comments, Frank

Ventilation Systems

Steve, I’ve been reading your great site and wanted to ask a few questions/make a few comments. With ventilation systems (including conditioned air)? You don’t seem to use ducted systems, is there any reason for this? In my experience (non-marine), dual 6-inch (15cm) ducts would be adequate for the living area sizes you have. I’m not thinking of round ducts, but more a box section mounted in the ‘eaves’ area. Your thoughts? – Craig

Registration and VAT

Hi. We are Dutch inhabitants, living in the Netherlands. We are building a 53ft sailingyacht by a Dutch yachtbuilder. Our purpose is to go living onboard and sailing all over the world.

1: Is it possible to registrate this yacht in the Channel Islands or elsewhere in the world.
2: Is it legal that the Dutch yachtbuilder can sell to us -or to our company- this yacht without paying VAT in the Netherlands or elsewhere in the EC. ( an VAT-0 option)
3: Is it necessary to start a company out there and how do we do this
4: Do you have experience with people who make arrangements for this
5: What is necessary to do so
6: What are the costs

Jaap en Renee from the Netherlands

Getting Ready to Go Cruising-What to Learn

Hello–My husband has gone off the “deep” end. He wants to sell everything we own and buy a 30-40′ sailboat and cruise the Pacific coast. I’m all for it, but I need to figure out how to prepare for an undertaking like this! Neither of us have ever sailed before, however, my husband is taking a 4-day ASA certification class in Seward, Alaska this summer and he has been commercial fishing in Alaska (Prince William Sound & Cook Inlet) for years. Please let me know of a book or a person who has gone from landlubber to sailor in a short period of time so I can start to figure out exactly what kinds of preparations we need to be making. The sooner the better–he wants to leave THIS summer! Thank you–Erin

Fresh Water vs Fuel Capacity

Dear Steve, Just finished your Offshore Cruising Encyclopedia. Great ideas and information. My wife and I just bought a Stevens 47 and hope to start applying your theories soon on our planned circumnavigation. Its 500 nm fuel range has me concerned though. Would you advise converting 50 gal. of its water tankage to fuel, leaving 75 gal. of water and a 20 gph genset powered watermaker? – Jim

Satelite Cloud Imaging Systems

Hi Steve, I have just discovered your website, and via Ocean Navigator have ordered your storm tactics book (Surviving the Storm). We are preparing for a 14-month trip first from East Coast US to Europe, then down the clasic trading route to Brazil, and through the Strait of Magellan in January, & up the west coast of SA, returing home via Panama Canal and the Yucatan. I have had a lot of people recommend the Sea Station unit to us. It’s a lot to jam on a well-found 36 ketch, but I am tempted. It has weather fax through the SSB as part of the software. I would like your comments. Do you think this is any substitute in regions where weather fax is unavailable? It uses low power and is no big deal for the computer, so long as we have power. Many Thanks, Andy.

Prop Painting

Hi! My dealer and I are having this contest, you know the kind 😉 about painting the prop shaft and prop. He’s already done it, and insists it’s "always done that way." I say no. I want the paint removed. The vessel is a 2000 Hunter Passage 450, the prop is an Autoprop. The Autoprop dealer (A&B Marine) recommends not painting but using their "Anti-Fouling Goop," a greasy lanolin compound. I have had to scrape the barnacles off the prop personally, so I know that bottom paint does not retard marine growth here in SW Florida. The Goop "seems" to work. It’s not been tried on a clean prop over an entire season. Comments? I love the books, videos, CDs and am amazed with MaxSea, especially the weather routing. Keep sailing! Errrr…… Boating!!!!!!

Prop Size

Hi, I’ve just finished your latest Storm Tactics, it’s grate.I’ve also read and loved your others. Can you tell me how to tell if my prop is sized properly.I own and am planing on cruising my Rob Perry designed Islander 32. It has a Westerbeak 25 hrs . My engine manual doesn’t say anything about max engine RPM. My current prop is a 12/14 two blade. At full throttel the RPM is 3400. I’m not sure what my hull speed should be,the waterline is 25′, and I can’t look it up in my Cruisers Encyclopedia because I lent it out and havent gotten it back.I can get .4 gal per hour and about 5kts at 1800 RPM. Is this too low of a power setting for long periods. Do deisel do better at higher settings. Is it hard on them to run at higher settings, say 3000 RPMs for extended periods.It seems that power settings above 2600 dont produce higher boat speeds.Any thaught on all the above would be a great help. Thanks

CSY Offshore 44

I am struggling to form a view on the suitability of the CSY 44 (1980 vessel with longish keel, but cut away at front I believe) for offshore cruising with a 4’11" shoal draft. A Cruising World article of 1997 said that the shoal draft (deep is 6’6″) has a significantly reduced righting moment and recommended the deep keel for offshore. I am interested in: 1. Stability/righting moment (this is important to me) and 2. Sailing ability for world cruising–i.e. how much harder is the shoal keel, the impression I am getting is that it is not good for that sort of cruising–to the point of not being suitable at all? Many thanks

Freedom Cat Ketch

Dear Steve and Linda, I’ve been in the process of looking for a used boat to spend the next number of years sailing…everything from long offshore passages to time in the Caribbean. For many years, in the late 70’s and early 80’s, I built very traditional wooden boats, sailed mostly traditional boats.

While looking at a 31′ Camper Nicholson the other day, I spied an older Freedom 33′ Cat ketch. She was really beautiful, and I remembered how fascinated I was the boats when they were first introduced. I know that you and Linda have pushed the edges of innovation in designing and sailing offshore boats. What’s your opinion of the boat as an ocean passagemaker? Thanks for your opinion and a great web site. Sincerely, Michael

Offshore Cats and Mac 65’s

Hi, After reading your observations about cats for offshore cruising we have started to rethink the one-year Pacific cruise we have been planning for our family (three adults, two children 11-13 ) starting next July. Any views on a Macgregor 65 as an alternative to a 40ft cat? Being UK sailors we haven’t come across these boats over here. Are they as fast and as tough as their supporters claim? Any comments will be very much appreciated. Thanks for a great site. Hugh & Deb

Stoboom Parts

We have a Stoboom on our Bristol sloop and I would like to keep and maintain it for some time to come. When we bought the boat several years ago, the sage wisdom from the people we spoke with was to ditch the Stoboom and go back to a conventional boom/sail rig.

We have got used to using the Stoboom and really would like to keep it in good shape. Any idea where we might find a source of parts for it? We have been unable to find anything on the Internet or by contacting Hood. Also concerned about eventual deterioration of the sail track over time. Thanks. – Roger

Free-Flying Roller-Furling Gear

A rigging question: What make (I assume ProFurl) and model furler would you recommend for our big reacher? The little Hood unit that was on the boat has a nice small headfoil for minimal windage but marginal drum capacity even at 5/16″ line for this big sail? These Spectra sheets and halyards are great! Have you had any problems with knots (bowlines) failing? Ref. June Sail magazine article. Thanks, Kurt

Big Roached Mains

Dear Linda and Steve: Two years ago I bought a steel kit form Bruce Roberts to build a voyager 495 (L.O.A. 49 ‘- 4") With a longish keel.

About one year ago I bought, directly from you, your book and CD “Offshore Cruising Encyclopedia” which, by the way, is the book I’ve have learnt more from. Pity I didn’t have it before.

You totally convinced me with what you say about mains with big roach. Apart from the technical explanations, your comments about them are: "There is absolutely nothing you can do to an older cruising boat that will increase performance as much as one of these sails, regardless of how much you are prepared to spend."

You have (or at least had) 82% of the rectangle of the luff and foot filled with sail in your actual boat BEOWULF and add “We now realize that we can go farther, adding more horsepower for little cost.”

Exactly two days ago I contacted Bruce Roberts (he is the one who really knows my boat) to ask him to produce me a new sail plan with a main of the same characteristic as the one you had on BEOWULF.

I’ve just been in your web site, as I wanted to buy some more books from you, and you can imagine my surprise when I’ve seen that you have just got a new main and mizzen of considerably different design than the original sails.

I’m really worried now: Have you found anything wrong with them? Could you tell me anything about the new design of your sails? I suppose you are very busy but I would be terribly grateful if you could answer me as soon as possible (the cheque to Mr Roberts has already been sent and now I don’t know whether I have to cancel the order).

All the best, Jose

Minimizing Discomfort of a Rough Passage

I have enjoyed your site very much for a long time. Into the Light (by Dave & Jaja Martin) has been "the book" for me. Both have been a major help in turning me from dreamer to setting the goals and schedules to make it come true. An amazing content of worthwhile reading from all authors.

My wife and I are contemplating a charter from Puerto Vallarta to Cabo San Lucas April 15-21 and the Captain has been straightforward in saying it will be an upwind and uncomfortable passage. He adds that it is only 300 miles. He has now departed Natal and will be out of touch for a time. We are left wondering about how long the actual passage might be. We are willing to endure a bash for a few days but wish to be up for enjoying Cabo to the fullest also. As we don’t personally know anyone to ask I thought maybe SetSail could help. Any advice or even general opinions will be greatly appreciated. Till my next order, Thanks, Everett

Self-Steering for Singlehanding in the Med

Hello Steve, I am planning a single-handed voyage to the Med. and a few years cruising there before a return through the Caribbean and am looking for advice on the ideal self-steering set up for such a trip. So far it seems that a wind vane plus a tiller pilot to assist for motoring is a good choice. This would work well offshore as it allows me to get some sleep in a situation (offshore) where going a little off course doesn’t matter too much. Sailing in the Med however requires more reliable course keeping and my question is whether or not the tillerpilot attached to the windvane will fill the auto pilot needs for this situation. I realize that there is a lot of motoring in the Med.in the summer but when it isn’t calm it is often blowing very hard and I am not sure that the tiller-pilot driving the vane will be up for this in the autopilot mode. I’d be most interested in your thoughts on this. Primary steering on the boat is a wheel. Regards, David

Speed Length Ratios/Hydrofoils

Dear Steve and Linda: Having discovered SetSail site, I want to tell you what a terrific boat you have designed in the Wind Horse. What I found particularly interesting is your break up with the dominant design rules of cruising power boats, e.g., trawlers.

While my limited budget allows me only to dream of Wind Horse, I am myself involved with pushing ahead my own dreams of ocean cruising. Having known your work, I have already given up my trawler-oriented mindset and I am rethinking the entire issue considering the canoe-like hull proposition you so beautifully materialised in Wind Horse.

Having said this, I’d like to know your comments on two points.

-according to the equation of displacement hull speed (1.2 times sqrt water level length in feet, am I correct?), a 85 feet-long boat could achieve a max speed of around 11 knots. But boats often go far beyond these limits, as are good examples your own designs. So, I confess I’m puzzled. Could you, please, shed some light on the issue?

-have you ever considered adding lifting hydrofoils to your designs (I think about Wind Horse) not, of course, to turn them into 60-knot-out-of-the-water rocket-boats, but to reduce their displacement and wetted area by say, 30%, so increasing speed & range? I think of hydrofoils added, say, to the keel and skegs, in order to compensate for, say, 30% of the vessel’s weight, or displacement, and adding to stability as a bonus benefit. Is this way wrong? If so, could you point the problems with it?

Thank you for your attention. Best regards, Francisco

Aft Cockpit Designs

Steve…Your recommendation to look at CAL 48 and CAL 46-2 was received. You stated though that you prefer aft cockpit. This does make sense. Some aft cockpit designs are better then others. Could you make recommendations for an aft cockpit design that I should be looking at in a used boat that has a long waterline as well as seaworthy? All your help is much appreciated in my quest for a used blue water boat. Corey
