FPB 78-1 Cochise Tests Survival Storm Tactic In Unusual Sea State

Many years ago, while researching ultimate storm tactics for our book Surviving the Storm (free download here), it became clear to us that, whether it was Fastnet 79, Queen’s Birthday Storm, or the 1998 Sydney Hobart Race, heading into the waves is often the best tactic in severe weather.

Because our yachts surf downwind under control making quick passages, and since in all but one of the serious storms we have experienced our natural course was downwind, we’ve rarely had the chance to experiment with truly dangerous seas on the bow. And while this most recent experience is far from what we would call a survival storm, the unusual sea state did give us a chance to test several FPB specific steering and throttle techniques, along with gathering a couple of ideas for improving electronics and night lighting layout.

The notes which follow, although aimed specifically at the FPB fleet, may offer some ideas to others who find themselves in difficult seas… Read the rest »

FPB History: A Look Back At The Design Cycle That Lead To These Yachts

Fifteen years ago, when we were just starting to build the FPB Series prototype Wind Horse, we put together a video on the design cycle that lead to this new design. There was detailed information on her drag and motion analysis, including tank testing, as well as the historical foundation from which her design was developed. Read the rest »

FPB 70 and 78: A Much “Kneeded” Perspective On The Next Generation Of FPBs

fpb782_matrix_conFPB 78-2 Matrix deck helm

The current America’s Cup spectacle has us entranced: unbelievable speed, maneuverability, and difficult sailing, the likes of which has never been seen before. The design and engineering required to achieve this level of performance is nothing short of astonishing.

The time to study what’s happening in Bermuda in detail is the result of this correspondent’s photography accident (night sky shooting on a dark dock), which resulted in a shattered kneecap and a forced hiatus from summer cruising… Read the rest »

It is a law in the yacht building universe that the sparkies (electricians) are always the last ones off the boat.

We thought this might be a good time to go through the DC battery bank and related circuits. Read the rest »

Anchor Chain


We are a couple from Alaska heading out this summer for a two or more year long cruise. We’re thinking of upgrading the anchor system on our 38′ steel Waterline cutter to something stout enough for exposed anchorages in places as extreme as Antarctica or Greenland. Currently we have 100 meters of 5/16 BBB with a 70# Bruce-type anchor and a 45″ CQR as backup. A fellow at Rocna anchors is advising us to go to G40 in 3/8″, and upgrading to a larger, 33kg or 40kg main anchor. My question, other than any comments/suggestions you might have regarding what you might advise us to go with, is do you think we can keep our 3/8 system (mostly our hydraulic anchor winch) by going to a G70 chain? I understand that Steve Dashew has gone to stronger, lighter 3/8 G70 so I wonder how you would think I could best apply this variable for our needs. Also, can you direct me to sources where chain higher in strength than G40 could be purchased?

I would appreciate any thoughts/suggestions you might have as we move towards making our final decision. Your expertise is very appreciated.

Kind regards,

Fred Hiltner

83 and 64

I am absolutely fascinated by your boats. Initially, the look was very unappealing…but as I started reading the beauty came out.
While I have a while to go until I am ready to stop practicing and begin my life of cruising with my wife, (my youngest is 13) my current boat of choice is the Marlow. But reading about your boat may change all of that.

I would love to get any info that you have with respect to these 2 boats.

FPB 64

Hi, Steve

For years I have enjoyed reading about your ships and now the FPB 64. I have a couple of questions, if I may.

1. With respect to the engine room air intake (and exhaust), do you have a way of closing the vent(s) in case of an engine room fire?

2. On the Get Home Conundrum, have you considered using a retractable thruster with rotation or azimuthing bow pump-jet thruster. Something for example offered by OYS thrusters. In addition to helping with close-in maneuvering, a continuous duly system could have a Get Home capability assuming the gen-set continues to run. If equipped with a closing plate could increase hull efficiently compared with a open thruster tunnel.

Storm Mooring Fitting

Hi Steve,

My Linda and I have admired your evolving burly long legged design philosophy for years. We sail out of Marion, MA on Buzzards Bay with trips up and down the New England Coast.

This year our good friend John Herzog has just acquired “Cloud Nine”, a lovely vintage Allied Seabreeze 35′ yawl, which he will be keeping this year on our helix auger mooring in Marion. The Bay is very open to the SW, and notorious for Hurricane surge. NOAA says this will be a very lively summer as you know.
I have suggested before launching John consider fitting a massive cable attachment point in the stem just above the waterline with added heavy blocking in the chain locker to accept a shackled 1/2″ steel cable or chain storm pennant. Length to the mooring top chain would be set to allow appropriate stretch of the two cafe protected 1″ nylon mooring pennants while applying most of the load to the eye at the waterline. John’s mizzen should help to somewhat reduce tacking on the mooring caused by the lovely sheer of the Seabreeze rail.
I have seen people attaching a steel storm cable to a single eyebolt in the stem, and feel that this may be vulnerable to side loading expected in storm surge.
Do you have any thoughts about such a rig? Have you ever seen a commercial fastener that would be a suitable stem shackle attachment point for a storm cable to secure a 13,400 lb designed displacement vessel, or do we need to have something custom made?

Thanks much and safe cruising,

Bill Bowers,
SV “Iteration”

P-Class Information

I am the recent purchaser of a 1962 P-Class Catamaran. “Mahitabel” is a 28 ft long/ by 12′ Beam Designed by Bud Platten / R&D builder for Hobie Catamarans.
It is to my understanding that boat designers Platten, Eric Witte, Ron Holder were fighting for a 1-man design, I am inquiring to see if Mahitabel is just in fact the Hull #1 that resulted.
She is a fiberglass/ kevlar reinforced hull with steering 3′ forward of AMA’S. Foiled foam Dagger boards forward, and 300 sq ft of sail!
Mahitabel is currently under rebuild in an owner/ repair shop Finleys in Oceanside.
If you could provide any knowledge of this beautiful machine,
It will help give me strength in each sanding stroke!

Hi Steve,

I’ve got a Sea Brake drogue and am looking at rigging up the lines to tow it…

The manufacturers data sheet that came with it said to use polypropylene …I talked to my rigger and he said “What ? that’s nuts….I think you need 3 strand nylon or polyester to give some stretch and give for the load”

I contacted the Sea Brake folk and they said …no don’t use polyprop, use braided polyester …correct me if I’m wrong but that’s what our jib sheets are and they are low stretch..

So now I’m a bit confused…

BTW the Sea Brake is a canvas-like material which is tapered at each end with gaps in the sides aft of the largest dia and a hole at the aft end…

I’d be interested to know what you think

Best regards to you and Linda

All the best

Anchor for rock bottom


Have a question about experience with anchoring on rock bottom.

We are planning to go cruising in Croatia and we have heard that there is mostly rock bottom there, and that this may pose some problems with traditional anchors. We find it a bit strange since Croatia has a fast growing charter fleet and we cannot believe that these boats are equipped with anything else than standard anchors. We have a Rocna 20kg, one fortress kedge anchor and one fortress hurricane anchor, but wonder if we should go for an anchor more suitable for rock.

The boat is a Dehler 37 Cr, waterline length 9m, dry weight 5,6 tonnes, cruising weight probably up to 7 tonnes I am afraid.

Do you think the Rocna will be OK, or do you think we should go for another spare anchor? And in that case what type? Space and weigh will be a problem.. The boat is flat bottomed, no sump.

Have been looking at a fisherman type like the picture below, which I can find to an affordable price .. And then there is the Luke, storm anchor which is very expensive in comparison.

BTW. Hope you liked our country! Saw that you visited Norway in your logs. Did you visit Oslo?

Aluminium Centreboard cruisers

Hi Steve,

Have appreciated your design philosophy and innovation for some time in terms of getting the best out of the comfort, speed and safety of a yacht.

Was recently looking around at a number of the more innovative french centreboard designs (eg alliage, allures, alubat omni, garcia) and would be interested in your view on their safety as a voyager.

I think Jimmy Cornell has cruised extensively on one – but that obviously doesn’t mean they are safe.

Hard to get any sort of stability numbers on them, which is obviously the first concern. Second concern I had was the ability of the shallow dual rudders to maintain steerage in large seas when running or beating.

Do you have an opinion on these at all?

Shaft generator

Aloha Steve and Linda,
We are building a 65′ Catamaran and trying to get as much of our electricity needs from solar and hydro. We chose a Duogen turbine but so far haven’t found a way to install it in a cat. Then I read that you used a shaft generator in one of your vessels in your cruises around the world. Can you tell us the pros/cons of the system and if it could be installed in a Cat. How much power should we expect from the shaft generator? we are running a 24V system in our boat.
Mahalo for your help and safe sailing.

nav software

Steve and Linda,

You have one of the most useful resources on the internet and I have learned a lot from your websites. I was curious what you currently use as navigation software and what you would recommend for someone looking to do world cruising and why that is the best choice in your very knowledgeable opinion. I did find your recommendation for Coastal Explorer referenced in your Nav section. I am pretty computer savvy if that makes a difference. I have tried to figure it out from the various pictures but (looks like VNS to me or maybe MaxSea) but what is best for you may not necessarily be best for me. I am building a motorsailor if that also makes a difference.

Thank you very much for your input.

Happy and safe voyaging.

Furuno Fax 30

Hi Steve and Linda,

Hope this finds you well and having fun wherever you are. In all
honesty, I have not been keeping up with you the last 2 1/2 or so years.

In trying to find something in the way of a review for Furuno’s Fax 30, I
see that you installed one going on two years ago. So, I just wondered
if you would have time to say a word or two about how you like
it(couldn’t find such mention on your site). Maybe one of my questions
is whether or not it adequately provides on it’s own the weather fax
function of a ssb radio? I don’t have the transmitter yet, so wondering
whether the 30 might let me put that off for awhile longer, but get me
used to using the faxes. Please refer me to something that I missed that
you have already written if you like.

Entry Level Cruising Boat

Hi, I watched you on TV last night. Wow talk about having a light bulb turn on in your mind. Anyway can you tell me what a good boat would be to start out with would be. I far from being loaded. My idea would be to live on my boat and make my way south. I’m at the very early stages of planning so knowing what boat I should be looking at is a starting point. Thanks in advance for any suggestions you can pass on.

Cleaning Sails and Lines

I am trying to determine what products are ok to use with

* Marathon 3DL 2004 140% Genoa
* Marathon 3DL 2003 90% Jib
* Ace Dacron Challenger Cloth 2002 Main

for light cleaning, I have been using just mild dishwashing soap and no bleach and rinsing the sails in the fall, but would like to see if one of the following would be ok. I would like to use

* 20 Mule Team Borax Natural Laundry Booster (sodium tetraborate decahydrate)
* Oxi Magic Mullti-purpose stain remover (Chlorine Bleach free) which has Sodium Percarbonate and Sodium Carbonate in it.

Are the two products above okay to use with the above sails?

Also my lines have some green mold/mildew and I’d like to see if I can use one of these on them as well
The lines are basically :

* Braided Nylon sheets and dock lines 1/2″
* StaSet-X halyards 3/8″
* Amsteel soling stay

I have not used any chlorox bleach.
I would like to use

* 20 Mule Team Borax Natural Laundry Booster (sodium tetraborate decahydrate)
* Oxi Magic Mullti-purpose stain remover (Chlorine Bleach free) which has Sodium Percarbonate and Sodium Carbonate in it.

Are the two products above okay to use with the above lines?

I had both Jibs coated with Sailcote Plus about 5 years ago to help with the mildew problem and it seems to be working but this year we had more than usual on one jib and I need to clean it better than mild soap would do.

Alubat – OVNI

what are your thoughts on the french OVNI range of cutters produced by builder Alubat?

they have several features – variable draught, all alloy construction, ability to be beached and a reasonable price – which i believe might make them a good starting point fo a long distance crusier.

my main concern, and it stems from having never personally sailed on a large centre-boarder – is their ability to go well to windward when required and their ability to cope with really rough conditions.

your comments?

Hi Steve & Linda,

I have been going through old blog posts and came across the series you did on SONAR. This reminded me of the recent update showing the install of a Furuno unit in a new 64. I just wanted to direct you to another manufacturer that you may not be aware of. They’re just across the sound from the folks who make your auto-pilot. (I don’t work for them in any way, just thought the product looked interesting.) I particularly found the testimony of a sailor who sails the Antarctic for a living compelling. It could prove to be a decent alternative to Furuno.

Happy Holidays,

Suggestions for Boat Improvement

Hi Linda and Steve,
My name is Gilles Philippin and I’m reading since the first issues you posted about WindHorse, I love the technical stuff. I’ve spent much of the time I was not working on my “Backyard Project” checking out yours, and it helped alot. Now that my boat has splashed, I would like to hear some real comments, handling predictions, what you would not do with her, etc ,since you are at the very top of my list of designer/builders,your opinion would make my day, especially if you find something that would need modifications or something else that could be improved.
Carlotte.C. is 32feet LOA, 31 feet at waterline, 8,5 feet of beam, draft of 41inches, air draft of 17′ (8feet from the wheelhouse down)and weight 12000 LBS (she’s all cold roll steel). She has a VW 1.9 TD engine, so we have 50 horses. Thank you for your generosity, and please forgive any misspelling for I’m a “Canadian frog”(from cold Quebec).

Bow Thruster Follow Up

Hello Again,

Just following up re a thruster. I see on the web that the FPB64 has a thruster. We are leaning twds. a retractable version.

p.s. We bought Hull #3, originally purchased by John Sabol who named her Tucan. He modified the steering config. to accommodate two wheels and moved the rudder back, extended the mast by 12′, swapped out the motor for a 140 hp more. Only put 450 hrs.on her before selling her to Peter Huttemeier, from Long Island, NY. Peter renamed her Bess and sailed her 35,000 miles before we bought her. We are thinking of a name change now as we are set to register her with the Feds shortly.

Engine Cooling

Steve, I read with marvel at the thought that you put into your systems. I also spend far too much time thinking about systems and I know of nobody in the industry that has it to your level. I’m just surprised about one thing…engine cooling. You go to great lengths to cool your AC and
refrig. using the “internal keel coolers” in order to eliminate all of the saltwater usually associated with it, but what about the engine? Why not
keel cool that? I have always felt that the weak point of these engines is
the belt driven rubber impeller pump and all of the intakes, strainers etc.
associated with it. I know that you are going to say that it adds heat to
the engine room, but my Nordhavn 40 was really quite cool with a keel
cooled dry exhaust engine. With an aluminum boat, you could even cool
through the skin.

An even better solution comes from the late Phil Bolger. He once drew a
unique boat that used an oil/air cooled Deutz engine. If you are not
familiar with it, these engines don’t have antifreeze as their coolant.
They curculate their lubricating oil and air cool it in order to cool the
engine. To me, it would be the ultimate…get rid of all of the usual
things associated with heat exchanger cooling and even eliminate the
complexity of a keel cooler….heck, they even eliminate an entire
fluid…antifreeze. Are you familiar with these?

One other unique engine that could be nice for the new 64 is these Steyr
engines that have an integrally mounted electic motor/generator. During
normal operation that generator could supply all of your DC needs without
needing an additional belt to drive it. In an emergency, it could be
driven as an electric “get home” motor powered off of the generator. I
think this could be a nice solution for a single engine boat.

Catamarans vs Monohauls

What would be better for cruising. I keep reading about how catamarans are so great because of speed and comfort. I also have been told that they are extremely safe, even in extreme storms. Is this true. What about monohauls, are they that much slower, I realize weight become less of issue with them but is the trade off worth it for cruising. What do you this of the Atlantic 57 vs the Oyster 655? Which one is better?

Greeting from Hamburg / Germany

So far i was only reading your comments and following your FPB adventures even to Europe. I am coming from sailing , actually from a Nordic folkboat and was thinking a lot about my next boat sail / power / motorsailor starting from some dutch steel motor vessels via Amel maramus up to Taiwanese Tayanas with my budget of 100 k EURO. I looked at old nauticat, Hallberg Rassies etc but nothing fits really.

One month ago I found small advertise in a harbour and meanwhile I am the owner of a nice boat which in never heard off or which I have ever seen. It is a Marimba 44 designed in 1980 by Dan Murray from New Zealand, built in Germany in 4.5 AlMng as round hull with centercockpit and interior was done in nice mahagony by another yard. A boat for 2 + 2 shortime guests, with a lot of storage , a sail locker in front of the saloon and head instead of add. Bunks, solid watertight alu bulkeads to separate the boat in 3 tight sections, no pressure water, but nice full batten sails etc. 13,5 m x 4 m x 2 m, 14 tons, 110 sqm

It looks like the boat found me and not I found a boat. So I can start some serious sailing. Thanks for your information and enjoy boating as long as possible.

Bow thruster

Hi y’all!

I can’t see a bow thruster on your boat. Don’t you have one or do you have a retractable?
If you don’t have one, why?

Induction Cooktops

hi linda and steve,

we recently sold our sailing catamaran we cruised on for 10 years and have gone to the “dark-side”. as i write this we are having a 47′ power catamaran being built in maine. we are just about 70yrs and in the future will limit ouselves to the usa, bahamas and the caribbean. no more sail handling in nighttime squalls!

it has been with great interest that we learned you are using induction cooktops.

power generation: we will have 680 watts of solar panels, 1260 amps in a house battery bank, and a 6kw. genset. in the past we could basically live off solar while anchored in the tropics even making water (12 gph at a draw of about 15 amps per hour). we will have “dumpster” style fridge/freezers that draw less than 5 amps and run 1/3rd of the time. all lighting is LED and we read and do not plan on getting a tv.

can we look forward to induction cooking? anything you can share about your experiences will be appreciated.

regards/glenn and pam cooper

p.s. we loved your high lattitude photos.

Domestic Water Pump

Dear Steve,

Will you be using the double action Surflo pump for domestic water on the 64? In other words, is it still a good choice or is there something better?

I’m looking at domestic water, washdown, RO feed and would like to do it with the same pump model.

Thanks for all you do,
Bill Shuman

Refer System


I’ve just put my C&C Landfall up on the hard for the season and will be refitting her over the next year. I noticed that you have decided to go with putting the keel coolers for your refrigeration in the freshwater tanks on the FPB’s. Sounds like a wonderful idea. I have two keel coolers with my system right now and now think I might consider your idea. Do you have any recommendations? Tank size, corrosion issues with dissimilar metals, contamination, etc. Also, do you have any input on refer/freezer boxes?

Just finished your meteorology book last month. Very well done. I was excited to see that Steve is a sailplane pilot! I think it mentioned him soaring somewhere out west? I’ve been around the sport for years and it was nice to see someone compare the two disciplines. Lots in common. Very cool.

Glazing Question

Hi Steve,

We just bought a 60’ aluminium sailing boat, 6 years old, and we are in the process of rethink many particulars for adapting the boat to our plans who are to sail even in cold places like Patagonia, and Antarctica.

Your site is wonderful; a lot of passion is filtering in your words.

A big wave destroying the glazing is one of our nightmares and so we found interesting your thumb rule for dimensioning the glazing.

We’ve read of your concerns about laminated glasses, but you don’t talk about double glazing to reduce the condense inside the boat in cold places. May be because with such thicknesses is not an issue?

Thanks a lot,

Mainsail Control


What do you think of the idea of putting the main boom vang on a circular track so the boom angle and boom height (sail twist) can be controlled. I guess this is the sort of system you would have had in your cats many years ago.

I guess it would alssuito roachy mainsails.

Do you think it could be an effective and efficient means of mainsail control for a large yacht with a shorthanded crew?

Multi-headsail Sloop/Cutter


Would you comment on the efficacy of the rig described below.

Let’s say we are talking about a 70 – 75 ft sloop/cutter with a DLR of around 60 – 70 – and beam to LOA of around 22% (typical of your style of hull).

It has a large foretriangle and fully battened deep roach mainsail.

The rig probably needs to be only low aspect given the area in the roachy mainsail and with say a 130% overlapping genoa in a large foretriangle.

There are 3 roller furling headsails (130% genoa, 90% jib, 60% jib) for the various wind ranges and an inner, probably permanently rigged, luff wire for a hanked on storm jib.

There are no backstays or runners and the mast has 25deg swept back spreaders.

Do you think this rig could work safely and efficiently?

What would be the main problems of the rig – balancing luff(4)/shroud tensions?

Advantages of British Weather


We’ve been thinking about the advantages of British weather. For one thing, folks from the Pacific Northwest of the US feel right at home. Then there is the British penchant for high end foul weather gear which supports a plethora of suppliers and pays for R and D which benefits the rest of us.

History buffs may recall that the island geography and industrial revolution are credited with the push to create the British Empire. But we have a different theory.

Open 60 World Cruser

Hi Steve and Linda, thanks for all your great work over the years.
I have to qualify this question with a few things. I am young enough (45) to still be crazy, I have extensive (30+years) of offshore (big boat) distance racing experience from the Islands to Nova Scotia, both shorthanded and with full crew, and I am a designer and builder (Houses and Commercial Projects) by trade, who has previously applied skills I have learned to such insane projects as helping to rebuild an Alden 42’ Cutter Rigged Yawl (replacing 77 out of 86 frames…).
I am in the process of considering my next boat. The intended use of this boat will be to do the “reverse” ARC, then bumping around Europe for some time, doing some races as desired, (Fastnet…) ultimately (if the mood strikes) returning after a year or two, or not, as the case may be. In addition while I do like and intend to have creature comforts, I have no problem with an austere (looking) interior (bare carbon or aluminum is fine with me).
Unfortunately one of your boats is not in my budget (although I have coveted one since you started), so I have been looking at used Open 60’s to convert to my idea of “the perfect cruiser”. Fast.
My logic (if you can call it that) is that from what’s available on the market, like the old P&J “Boomerang” while a fantastic boat (I have raced her) for the most part could not be simply modified to my needs (also a bit big, I think 60+/- is my max). My main issue is draft, so I am considering as part of my budget a lifting keel (or even canting/lifting) with a target draft of 4’. What is your opinion of the various lifting keel methods, and their relative strength/safety? Having had a near miss with a partially submerged container on a night with no moon doing 20+ Knots, I have some concerns.
In addition what are your thoughts on “detuning” (reducing the sail area (slightly)) such a boat for the displacement that I would have, since I will not be carrying the sail inventory or supplies for a non-stop around the world trip (I will have a complete inventory, but carrying 9 chutes/code-0’s – 6 Jibs and – 4 Staysails is more than I would use). My goal is to have target speeds of about 20 KTS reaching and 13 KTS Beating in 15 KTS. I would like to eliminate the runners and struts associated with such a large rig.

Thank you in advance.

Which alternator do you use?

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,

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

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

Skegs – Worth It?


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


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

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!

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
