Which alternator do you use?

Hello, I am interested which alternators you are using on you boats. I have read about 2 pcs. Electrodyne 150A/24V. Gut on the website of Electrodyne they also say to have 250A/24V pieces. Would that be an option as well? Are you not heating the batterie’s to much while loading the them that fast? How many Amp/hrs are they in your boat? Thanks in advance, Berend Read the rest »

WASHING MACHINE

What do you think about having a washing machine on board a boat for a family of four about to go cruising for a couple of years (maybe more)? We could make the space for it. Read the rest »

Hull Plate Thickness

Steve, I believe the hull plate thickness on the FPB65 is 12mm. Can you tell me what you used for the FPB83 and Beowulf? What was the deck plate thickness? Thanks, Henry Read the rest »

John Deere power

I have a question regarding the John Deere propulsion engine: Does the engine have enough power for maneuvering the boat together with driving two alternators and a hydraulic pump? What is the capacity of the hydraulic pump connected to the PTO and is the bow thruster also fed by this pump? If yes, how strong is the bow thruster and can you use full bow thruster power on low engine RPM? Thanks in advance for your answers. Another question regarding the alternators: How long does it take to fully recharge 25% percent charged batteries (how much Ampere-hours is the battery bank totally?) with the two alternators? Regards, Berend Hartman Read the rest »

Wharram style “soft wing sail” viability on a monohull

Hi Steve, I am designing a rig for a 42′ cruiser (monohull). Due to the nature of the hull I need a lot of sail area and a low center of effort. James Wharram, about 20 years ago, developed what he calls a “soft wing sail”. It is a gaff rig with the leading 1/4 of the sail made up as a sock which slides over the mast, in place of hoops, lacing, etc. It’s obviously efficient aerodynamically. My concern is that friction between the sail and mast could cause problems with reefing/dropping the sail. Wharram has been using the design now for decades and says that there is no problem, that it can be dropped on any point of sail. He has lots of boats sailing with this rig. It seems to me that if this works on a cat it should work on a mono as well. I’ve crunched the numbers on rigging loads and mast compression and these can be made to work. I’d greatly appreciate your thoughts any any experience you have to share on how this rig might work on a mono. Regards, Paul Read the rest »

Skegs – Worth It?

Steve, Some months ago I purchased an uncompleted Turner 46 hull (Tripp design) and am in the middle of its conversion into a 46′ motorsailer. I realize this approaches lunacy, but I’ve wanted to build all my life and after two aborted tries, I’m older, wiser, and have couple of more dollars to spend and so am off down this road again. Your Offshore Cruising Encyclopedia is a well worn design reference as is/was your website. Of particular interest, and the purpose of this e-mail, was a web page on your old site which discussed the appendages on your first FB. I really liked the propeller shaft skegs, and wanted to emulate them on my motorsailer, however the images have been removed from your new site. Not to worry, as I have the basic idea but I would be very much appreciative if you could share a few of brief thoughts on the pros and cons of these skegs (vs. an open shaft and strut) on a motorsailer. I’ve searched in vain for some internet discussion on the topoic but have not found much. I guess my question boils down to whether or not you feel the added protection of a skeg to the shaft and prop outweigh the added surface area and maintenance complexity (changing out cutless bearings) in a motorsailer application. I feel that in my case, directional stability and maneuverability issues are a push, but would be very interested in hearing your thoughts on the subject. Best Regards, Doug Brown

Genset vs Alternators

Steve, I had a question about the cruising alternators on the main engine. I have been reading Ken Williams’ blog and there was a significant amount of traffic on this subject. Bottom lime was concluding that they drew more power, hence fuel, then simply running there normal 20kw generator. They went on to suggest that Nordhavn as a company was no longer installing them on their boats. I know you area a big fan and I was wondering if you could shed some light on the subject thanks Scott

Exterior use of 6061 alloy

Hi Steve, As a long time builder, user and owner of aluminum alloy boats perhaps you can answer this question: How does the odd bit of raw 6061, above the waterline , but on the exterior, fare visually over time in comparison to 5086? In particular, we’re building a Dix 43 Pilot House and I’m looking at using a 3″ half pipe extrusion as a rub rail down each side and it is only available in 6061. The hull plating is 5086 H116. The alternative is to buy vastly more expensive 5086 schedule 80 pipe and rip it on the table saw. I don’t mind spending when it’s justified but don’t want to waste money. We love the look and practicality of unpainted alloy, but my experience in non-salt environments with 6061 is that it can look pretty nasty after awhile. Perhaps it’s just a matter of an occasional scotchbrite rub-down. The other place we’ll be using 6061 is for the rudder shaft . It’s a spade rudder with a 115mm diameter shaft and Jefa self aligning bearings. Appearance is not an issue here, and I think the 6061-T6 will be stronger than 5086 . Do you think corrosion could be an issue on the 6061 rudder shaft? We will have a comprehensive anode system. Thanks so much-I love the new site format!

bottom paint for aluminum boat

Steve, I have a Lavranos-designed aluminum 13M cutter. The bottom has 6 coats of Interlux 2000e epoxy barrier and a couple of coats of Interlux “trilux 33″ bottom paint. What brand of bottom paint do you use in warm climates. Thanks.

Getting to the Bottom – Rocna

There is considerable discussion about Rocna vs Manson vs Spade floating about. This discussion is somewhat contaminated by the defensive jabbing amonst some of the designer/manufacturers. Given your tacit endorsement of the Rocna, can you give us some real life (NZ to UK via Alaska) insight into where the Rocna proves to be superior and when it does not (e.g., bottom types, fast currents and shifts, storm conditions). Thanks!

Furuno Sonar Flange

Dear Steve, I am following your gear review used on your new boat carefully as I am building 54′steel sail boat (Bruce Roberts). I am interested in the Furuno Sonar that you have recently installed. In your review you are praising Furuno for designing the flange to fit a 6" pipe.

"Furuno’s engineers were thinking ahead here, as the pipe is a standard size, as is the flange."

From what I can determine the standard flange for 6" pipe is not exactly the same as the flange supplied with the sonar.

My questions are:
Did you accept the difference between the two flanges and just bolted them together?
Did you have a metric flange installed instead of 6" one?
Or is there US model of the Sonar that comes with a 6" flange on its housing?

Integrating Nav Equipment

Hello, We have just discovered your site and are very excited about it. With your help we may finally be able to figure out our best options for integrating a laptop, electronic charts, gps (none of which are yet purchased) and our existing auto pilot (Autohelm 4000). We have a 30ft Catalina sloop and are somewhat electronically challenged. We plan on using charts from Maptech, NOAA, Explorer and maybe The Captain. Anything you can suggest will be of great benefit. Thank you.

Navigation Course

Hi Linda & Steve: We have recently purchased your four-volume series and find them extremely helpful. We are just beginning our sailing career and are using your books to get that 10-20 year jump (as you say). The message that stands out more than anything else is the seriousness of sailing and being prepared.

Navigation seems to us to be the most important subject (at this point). We haven’t gotten to the weather book yet, however, I know it’s just as important but one thing at a time. We live in Phoenix and keep our boat in Seattle. Can you recommend a school that offers a good navigation course in Phoenix? We wish to keep our boat on top of the water unlike Jubilation and others ( very sad).

Thank you for your help and sharing of invaluable information. Cheers, Larry

Raytheon R40X Radar for World Cruising

I currently have a Raytheon R40X unit but it is an old unit (while very good) that is "dumb" and cannot talk to anything else. I can’t decide whether to replace it outright or add a 20 mile Foruno on a pole at the stern. I intend to world cruise the boat beginning in 18 months. Any thoughts? The boat is Gulfstar 50 Sailmaster that I have been updating for the voyage, and while she is older, she is a very beautiful heavy cruiser. Thanks again, Jim

Combining GPS with Older Instruments

I have B&G autopilot circa 2000 at the pedestal (in the network series…i.e. network PILOT), network DATA at the nav table, wind, and a repeater at the bulkhead. I also have network WIND. I have an old Raytheon (as was) chartplotter(not working), and there is an old Raytheon plotter/radar (RL9) mounted on the pedestal reading from a Raytheon antenna mounted on a pole. It gives a reasonable radar signal.

My yacht is a classic 1970 Swan 40 Sp&S. design. She is now in Antigua.

My B&G instruments work perfectly. They are all Network B&G instruments I have an older Raytheon GPS antenna also mounted on the pole. I do not know if it gives NMEA(0183) output. My nav station is run by my laptop running Maxsea software and connected to a Globalstar satphone.

I propose to buy a small fixed GPS reader to be mounted at the nav station to give position…I assume it might be able to read the signal from the existing GPS antenna though if not I can replace it with a suitable antenna, and give a NMEA signal to my laptop computer. Ideally I should like this to be a B&G GPS (if there is one in the network series). Please advise if you know of one.

Should I buy Networknav? Any info comments? Where can I buy…any second-hand from upgrades? I need a good GPS receiver as I understand it.

I want to keep the B&G instruments I have. I want to make a system from what|I have that will speak thru NMEA to my laptop. Will Maxsea read any NMEA signal and overlay it on any of the charts loaded electronically. What output signals will MaxSea give to autopilot? Do you have any observations/advice?

Digital Cameras for Cruising

Hello from WA state, can’t tell you how much great info your site brings us, thanks for that! I was wondering if you have ever done research on cruisers’ favorite pick for an all-around good (at least weather-resistant) camera? I would assume most folks are getting into digital now. Any ideas? Thanks…we are selling out and moving on board next spring to play for the summer up here then head on down the coast mid-Aug. CAN HARDLY WAIT!!!!!!!!!!!!! Warmly, Dianna

Sonar

Dear Steve, I am thinking of installing the Interphase http://www.interphase-tech.com/pcview.htm forward-scanning sonar on the steel 55′ sail boat that I am building. It would seem that every sail or power boat should have one of these in order to be able to see what lies ahead and to be able to avoid any obstacle. But so far I was not able to find anybody that has had any experience with it. So I am writing to you with a hope that in your research of the new electronics for your FPB you may have looked at Interphase sounders, or you may have heard from someone that used it. Would you please share your thoughts regarding this gear? – Remek

Nav Instrument Integration

I’m building a 65′ Cruising Cat, and am at the beginning design stages with my designer. While he’s working on that, I’m doing the research for the nav functionality. I’m somewhat perplexed by the array of nav equipment available from the 6-10 major suppliers and how things will fit together along with the MaxSea software, so as to get maximum coverage AND integration. Should all the items come from a single source and, if so, which would you recommend in terms of reliability and repairablilty
considering the number of places one can find ones self while circumnavigating?

Cruising Boat Choices

Dear Steve:

Thanks so much for your various books. I just finished devouring Practical Seamanship. I have gained greatly from reading and practicing the insights shared, particularly sail balancing and heavy weather techniques. When read in conjunction with the video’s, the books are even more informative.

I presently have a 461 Beneteau. I like it very much. My wife thinks it is a bit too sporty & light. We use it for coastal crusing (West coast). We are in the beginning process of evaluating boats which are better designed/ suited for passage making. Like most everyone, we would like to sail BEOWULF, or its equivilent, but it is not likely to ever be in reach of our budget. I personally would like a Sundeer 64, but it is uncertain whether one would become available, or be affordable. As with so many others who have written before me, I am seeking advice to help with my quest.

We are looking to spend $400-500,000. I had been thinking of the Amel Super Maramu 53, but after comparing its hull design to that of the Sundeers/Deerfoots, it appears more suited to light conditions. Others we have considered seemed a bit too beamy and/or had keel/rudder designs which were not conducive to surfing. Any thoughts on production/semi-custom boats that we should focus on? My inclination would be toward a ketch, but I’d be happy with a cutter rig.

Thanks again for sharing so much and considering my questions. Linda has been quite an inspiration for my wife, who really only likes warm days with the wind behind the beam.–Mark

Email While World Cruising

I am seeking advice re the best choice for setting up an email account for use during my family’s upcoming sail around the world. My crew are my wife and two young daughters (5 and 8). We plan to depart in September 2003 from Groton CT aboard our Westsail 32. First of all, we plan to have a ham radio Winlink email address (if I can just carve out enough time to study for and take the tests!). But for sending and receiving photos and large attachments I gather that we should consider having an email address that we can access from Internet cafes and similar locations using our laptop. Do we need to have a subscription internet service provider that we would dial into from landlines at foreign ports? If so which is best? A free one like Hotmail (I think it’s free)? Or do we need to pay $10 to $20+ per month for an ISP like Earthlink or AOL? Do we simply need the email address and then plan to use the Internet cafe’s or other retail location’s internet service provider to gain access to the web. As you can tell, I am having trouble figuring all this out and would really appreciate your guidance as to whom we should contact for the best, most current advice. Thank you for whatever you can tell me to get us headed in the right direction.– Doug

Chart and Radar Integration

Hi Steve, I don’t know if you covered this anywhere (couldn’t find it in your books, SetSail or in MaxSea) but I have to renew/upgrade my Radar. Obviously want to get one with Mini ARPA output for overlaying targets on MaxSea/charts. However, in addition, sailing mainly shorthanded, would like (need) to have chart, radar and overlays (if possible) on a repeater in the cockpit.

All the main Radar/Chart Plotter suppliers (Raymarine, Furuno etc.) don’t have any protocol for third party suppliers of chart software to repeat via their screens either main or repeater. As far as I found out so far, only RayTech Navigator (with additional Racing module upgrade) allows their propriety software to connect via their "Seatalk" or HSB and one (or more) of their Radar/Plotter displays.

In other words, it seems to me only Raymarine, if you buy their chart software cables, HSB or Seatalk etc. is able to achieve this desirable requirement. That would mean dumping MaxSea (of which I have an investment already) and going all RayMarine? (coincidentally I have all RayMarine ST 60′s instrumentation in the cockpit). All the other systems are capable of Radar/Plotter as main screen with repeaters (Furuno’s NavNet for example) in cockpit, but then you have to buy their cartridge Rom’s with the charts again and that would cost a fortune.

Any suggestions on how to "get repeated" in the cockpit without costing a fortune in waterproof tablet computers? Also, are there any Radars on the market which give a signal to operate on a PC/Laptop which could then be duplicated somehow to a screen in the cockpit (along with the chart plotting of course)? (what about using a PDA as a dumb terminal via wireless? bit small I know, but thinking of cost).

Appreciate your views/advice/knowledge on this subject. Kind regards/George W

SSB vs. Iridium/Globalstar

Question regarding SSB vs. Iridium/Globalstar…..I read the nice item on Setsail.com on Iridium/Globalstar and agree that it is coming into vogue economically for data communications/e-mail, etc….It is definitely easier for everyone on board to use in a crunch. But don’t you lose the flexibility to participate in net calls, etc.? It seems that there are always tradeoffs…You can access SailMail via the Sat. phones, correct? Also, I’m upgrading my sailing info instruments (wind direction,speed,etc.). What are your thoughts on a good manufacturer of these items in reference to MaxSea interface? Thanks, Ed

Medical Insurance for Cruising

In the Bernhardts’ April 01, 2001 discussion of their cruising budget, they state that they pay $2280 for medical insurance for the year for the whole family. I’d like to know which insurance company they use. Their boat insurance is fairly inexpensive also, since their cruising area includes Europe…Love this site. Thanks. Claire D

World Storm Patterns

Hi, I am enjoying reading our book “Surviving the Storm”. I know you could not cover all the topics, and I have not read the whole book yet, but I could not find data or reference to world storm patterns. If one was chicken, and wanted to avoid category two and three heavy weather storms (page 16), what cruising routes could be planned, and where not to be at what time of year? I recall some published charts that show wind direction and speed at various locations. What about information on routes and the best time of the year to avoid bad storms. Could you name a few good sources for me. I get the hint that New Zealand is risky at best. If I missed this information in your book, please let me know where it is located. Thanks, Mike

Prioritizing Electronics for Cruising on 42′ Cat

I found your web site today and was fascinated with all the possibilities. We are in the process of buying a 42′ cat and will be sailing from the US East Coast through the Panama Canal and out to the South Pacific and points beyond. The boat does not have anything other than self steering and basic instruments and we would like to equip with radar, gps, plotter, etc…running into a PC and of course not spend a fortune. What would you suggest as someone who obviously has a great deal of experience? The route plotting seems like a great idea and we will have a sat phone but are unsure about a SSB. Thanks, David

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

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

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!!!!!!

Opposite Rotation

What effect is there on propeller performance and vibration when fitted in the opposite rotation to that recommended by the boat builder?

I just purchased a 9 year old Grand Soleil Maxi One (19.5m) and am having a lot of problems with engine & MaxProp giving a lot of very bad vibrations and engine not being able to obtain correct cruising revs (should be about 2700/2800 rpm–and getting black smoke when revving above 2200rpm).

Obvious answer is the prop is over pitched. However, on checking with MaxProp rep here in Athens, he just serviced and refitted the prop with 20 degs with right rotation. According to the Manual on board from the builders (Canteir del Pardo) the prop should be 14 degs–Left Rotation.

Of course the over pitching of the prop answers the problem of the engine not revving etc, but would the wrong rotation cause increasingly bad vibrations the more rpm’s applied?

I need some urgent advice because the incorrect running of the engine over the last 8/9 years (by previous owner) has caused all sorts of problems including overheating, broken pipe in heat exchanger and blown gasket leading to water into the cylinders and turbo etc on my recent outing with service engineers on board testing the engine after service. Thus, decided to put new engine as do not want to have further trouble/time/expense of trying to renew/overhaul existing engine.

Obviously have to find also a solution for the bad vibrations, but I cannot get Maxprop or del Pardo to reply to my emails and faxes.

Diesel Electric Drives-Prop Efficiency

I wonder if you have any opinion on electric propulsion? I am considering re-powering with a Solomon system. I have a 30hp Westerbeke diesel at this point. I am cruising full time with lots of hours at anchor. Comparing prices, diesel/electric, is a definite apples/oranges situation, with the result being that I may decide based on my dislike of the internal combustion engine. Certainly would appreciate your reaction to the this concept used in a cruising sailboat. Ross

Max Prop vs. Autoprop

Dear Steve, I have a Kelly Peterson 46 with a fixed 3-blade prop. I want to change it to a feathering prop. I am intrigued by the continuously adjusting Autoprop which is supposed to match pitch to engine rpm and twist more or less flat to cut drag under sail to 85% of a fixed blade prop. I wonder what happens to the independently adjusting blades when barnacles form and they become unbalanced. Maxprop has less drag under sail but its pitch is optimized for max rpm and falls off (like fixed props) at lower engine rpm. Do you know how well these things work in the field? Any kudos or horror stories. Thanks, Carl

Controllable Pitch vs. Max Prop

Steve, I was fortunate to have sailed with you and Linda in Ventura a number of years ago and got to back your boat into the slip easily due to the max-prop. I need to decide between a max-prop and a controllable pitch prop. It seems that the max-prop might have the advantage in backing where the cpp shines due to ease of adjustment underway. Which do you prefer and why? Robert

Max Prop w/ Shaft Generator

In your very valuable Encyclopedia (looking forward to read the heavy weather issue) you briefly mentioned a way to generate DC power with a MAXPROP or AUTOPROP. Is there any description available on this setup? My boat is a Gerard Dijkstra designed 77 ft centerboard shooner (steel, 60 tons) and a MAXPROP is fitted but I am thinking of changing to AUTOPROP (only for performance when maneuvering). Is it possible to do the same trick with this prop? I hope you find the time for an answer. Best regards, Paul

Feathering Props

Question: I was going to install a feathing prop on my Nautic Saintongue 44 during this spring’s haul-out. Presently, I have postponed this investment because I met a couple in La Paz this winter who had a feathering prop on a Passport about the same displacement as my boat. I asked them if the prop (maxi) was working for them. They replied that if they had to consider it again, they would not do it again. Basicially it was not worth the investment.

So, what is your opinion on replacing a fixed three blade with a maxi type prop? From manufacturers reports I have read, an increase in speed will be realized, but on a 25,000 lb. displacement boat, is the investment worth it? I do not race, but like to get from one place to the next as quickly as possible.

What prop has worked best for your boats over the years? Mike

Oversize Prop-Undersized Performance

I replaced my fixed prop ( 3-blade 16 RH 10) with a 17 RH 10 Flex-O-Fold 2-blade folding prop. I have experienced much improved speed under sail and not bad performance in reverse. However, I am unable to get full cruising RPM in forward and because of this am not able to motor cruise at much more than 4.3 knots. My vessel is a Nautilus 37 with a 35 hp Yanmar diesel. Also I am experiencing vibration at 1900 RPM which I did not have with my fixed prop. Any suggestions? Ron

Offset Propellers

Hi again. We are in the process of installing a diesel engine in our Mirage. All was going according to plan, until a fellow boater mentioned crabbing, and warned us that placement of the prop is critical. If not offset, the boat will ‘crab’, worse in reverse, than in forward. Next Saturday, the hole is being cut through the hull. I’ve had a look through the Encyclopedia, but can’t find much about proper placement of the shaft/prop, and although many of my boating friends have heard of it, no one can elaborate. I’ve looked at the last few boats in the area that are still out of the water, and find that the shaft is placed dead-centre. Do you have any advice, or do you have a publication that explains the concept? Your help is appreciated. Jim from Canada

Autoprop

I am thinking of changing my fixed three-bladed prop for something that causes less drag. The Autoprop from Brunton’s Propellers seems very interesting. What do you know about it? P.S. Your Encyclopedia is a fantastic source of knowledge!

BEOWULF’s Prop

What kind of prop do you use on BEOWULF and is it a feathering prop or folding? I know that you do motor sail and I wonder how you came to the size and pitch that you needed for the boat. I also liked the Bermuda story about the weather, you made a very good move by moving to a new location, it could have been a bad situation had you not moved. Good Sailing, Gary H

Prop Size

Steve… I have your Offshore Cruising Encyclopedia and I have almost finished building this 35′ steel sail boat. I’m having a little trouble sizing the prop…Boat is 9.5 tons…engine is Farymann 32 HP…Prop is 16×13, 3 blade… Max. RPM under no load conditions is 2400. Max. RPM in forward is 2100 at max hull speed of 7.5 kn…reduction of transmission is 2:1. Should the max. R’sPM under load be closer to 2400?… Should top speed be reached before 2100?… I hope you can help with this … Thanks–Basil

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?

Prop Shaft Generators

Hi Dashews, Have 3 of your great books and getting a great deal from them. My yacht has a free-wheeling engine shaft and I understand someone has developed a system whereby you can mount an electrical generator inside the boat to the engine shaft via a belt and a set of pulleys–have you any information on this system, or contacts where it could be obtained?

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

Bow Roller for 110 kg Bruce

Hi Steve, I took your advice and got the next size bigger Bruce for my 46 foot, 28 ton displacement schooner. The new 110 lb anchor is quite a conversation piece sitting in the shop while we try to figure out how to mount it. We don’t think a standard bow roller will work because of the 90 deg turn needed to bring the shackle and anchor up onto the roller. It’s difficult enough with the current 60lb CQR. We’re thinking that a pivoting bow roller may work but I’ve not found any rated for that kind of weight. Can you recommend a roller or have any suggestions? Thanks, Carl

Anchoring System for Hurricane

Aloha from Hanalei Bay, Kauai. I am in the process of making a hurricane plan for AVALON, one of your beautiful, well thought out and seaworthy Sundeer 60s. She is now happily living in Nawiliwili, Kauai.

I think that in the event of a hurricane I will anchor her in the harbor rather than leave her at the dock. I am considering a 50 lb Danforth style anchor on about 20 feet of chain shackled to the 120 lb Bruce on the 5/16 schedule 70 300 ft anchor cable. I also plan to put a 30 lb kellet on the chain rode. Thoughts? Aloha, Scott

Anchor Shackles

Hello, Thanks for your excellent books and CDs. We have purchased your Encyclopedia and CD but have not gotten off cruising to the Carribe yet. Soon though.

In following your recommendations on anchoring, (we purchased a 65 lb Spade Anchor and will back it up with 200 feet of ACCO 3/8s Chain with oversized links on each – and following your admonition it must be the right size as our dockmates have laughed at the size we bought), but we had a question as to what shackle you are using with your system. We want to insure that our shackle will not be the weakest part of our system. Can you advise the maker and size of shackles in use on your boat? Ed & Sue

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

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.

Anchor Windlass with Multiple Anchors

Steve – I am preparing to install an anchor windlass on my light displacement 43′ sloop. Primary anchor is a 45# CQR with 75′ of 3/8 HT chain + 250′ 5/8" nylon rode. Secondary anchor is a Fortress FX-37 with 25′ of 3/8 HT chain + rode. I will carry a 100# Luke storm anchor. My question is how to manage multiple anchor lines/chains with a single windlass. I would prefer a low profile vertical windlass to keep weight down and stay out of the foredeck crew’s way when racing, and am willing to live with rope/chain splice and redoing same when any splice wear starts to show. But I do not believe this will enable handling two anchor rodes? Adding a drum to the vertical windlass will handle the second rope rode, but not the chain. What do you suggest? Thank you. – Bill

FPB Anchoring

Dear Steve Dashew, Many thanks for the fine web postings on the new powerboat. I have a question regarding your anchoring setup. How do you maintain the strength of the G7 chain through your shackle attachment to the Bruce? Do you have ACCO install an oversized link and use, say, a 5/8" shackle? Or do you have a source for high-test shackles? I am building a 19m powercat designed by Malcolm Tennant to be launched early ’06. See you in Patagonia! Thank you, Bill

Anchor and Rode for Circumnavigation

Hi Steve – You were kind to advise me regarding the draft for my new boat last year. Now I am in the process of equipping the boat for a circumnavigation primarily in the tropics. My boat is a 57-foot sloop from X-yachts in Denmark with little windage, the weight is 20 tonnes. I am going to use the Bruce as main anchor and the suggested size for stormy conditions is 30kg, but as I remember from your book you suggest to move up in weight, which in this case will be 50kg. Can you help me to decide between 30 and 50 kg?

I am bringing a 100m stainless chain. Can you recommend an appropriate dimension? Kind regards, Mogens

Sailing at Anchor

We are planning to buy a SAGA 43 which is a very narrow boat, with a narrow bow. We have been told that the boat sails while at anchor. We were wondering if this is a problem simply because of the narrow width and bow, and if there is some way to counteract and rid ourselves of this problem by anchoring techniques, use of wind vane, use of a riding sail, etc. We know that the Deerfoot is a narrow boat and hoped that your experience with narrow hulls might put us on the right track. We would appreciate any suggestions you might have. Thank you. Sandy

Simpson Lawrence Claw

Steve – It’s finally time to take our Deerfoot 61/63 out the St. Lawrence from Chicago to Maine for the summer, then the Caribbean for the winter and the Med for the following summer. I have a question regarding anchors. I have a 105lb CQR that works well but needs replacing, as the point has rusted through. I am considering the purchase of the following: 105lb CQR, 140lb CQR, 110lb Bruce, or 110lb Claw (Bruce knockoff). Which would you recommend? In particular, have you gotten any feedback on the Simpson Lawrence Claw anchors? They typically are priced less than 50% of the same size Bruce. (FYI, I also have a Fortress FX85 and a 100lb Paul Luke fisherman anchor as backups.) Thanks in advance, Mike

Electric vs. Hydraulic Motors for Windlasses

Hydraulic motors. You mention the problems with running your anchor windlass, the need for large wire size to minimize voltage drop on the long run to the bow. Why not power the windlass with a hydraulic motor? You already have a pump onboard for the auto pilot, even adding an additional pump would provide some redundancy for the autopilot system. Now all you need is a tiny motor and a couple skinny (1/4 in od) lines running up to the bow. These motors are robust, simple, easily speed and overload controlled, corrosion resistant (I own a chemical plant, believe me I know about corrosion!), very lightweight… I first saw these used at a plant in Norway. All the agitators drive motors (probably 10 total) were run by a single hydraulic drive pump. Speaking of multiple motors, how about that big power winch you use on Beowulf? Slap a hydraulic motor on that thing too and get rid of the need for a 24 volt electric system all together!

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

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

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.

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.
