I’m looking for real-world feedback from sailors with experience running underpowered auxiliaries. I have a 1984 Bayfield 32C (approx. 32 ft LOA, ~26 ft LWL, ~9,000–10,000 lb displacement) currently equipped with a Yanmar 1GM 7.5 hp diesel. The engine is extremely well-maintained and runs like...

Im starting a project of designing, a large, fast, cost effective keel boat that is possible, I want all the advice you guys are wiling to give including software to draw, design, and build in (not too expensive) as well as any physics or mathematical things to pay attention to. I am looking...

Hello! I'm new here. My name is Nicholas Malinovsky, and I would like to share my project with you, which I have been working on for the past two years. It is a 27-foot aluminum cruising trimaran that can be easily transported on a trailer. I designed and built it myself, and it is almost ready...

Hello, boat design community! This is my first post on this forum, and I anticipate many more to follow. I am starting this thread to document my work over the last couple of months and will continue to do so in the years to come. Since it is my first post, I think it makes sense to...

{27’ junkrig, fibreglass and cedar- almost in final stage for expedition. It is equipped with Yamaha t.9.9 exht. Specifics of model of the boat still under investigation due to hazy record keeping of previous owner.} Hi, folks thanks in advance. I’ll add more photosin the morning. 1. So...

Got this Ski breeze sailboat as my first to learn in. Built in sweden between 1957-65. 5,6x1,8m 340kg displacement. Only done 5 short trips yet, but it is very addicting. Unusual boat and hard to find anything on the web about it. Anyone having any experience with such a boat?

Hi all, How high above the waterline should davits (or, really, a dinghy's bottom) be? It is understood that dinghies can only stay in davits in protected waters or on short coastal passages in fair weather.

I have heard scuttle butt that ceramic coatings (finishes) have been used on bottoms of sailboats to enhance (reduce) drag. I think there is an Opti builder that touts a ceramic treated bottom. Might make sense, but for a few aspects. Any experience out there? Thoughts and comments? Thanks, Chaos

I am currently designing an extremely unconventional sailboat, which we as a couple hope to sail around the world, and if we are successful, that would also set a new Guinness World Record for circumnavigation in the smallest boat. I have been thinking through a lot of things on my own, and I...

Hello, I am currently living in Latvia, and am interacting with a man selling a 1977, 7.7m-long "North" sailboat. He does not know what the original model is in any more specifics than that. (-It may or may not be "North", as stated.) With this limited information, I've been unable to find...

Hey all, im currently designing my next project and wanted to reach out to those minds with more experience. To preface i am an environmental and structural engineer, specializing in hydraulic and hydrological engineering. I understand the issues scaling plans up or down and that it isnt a...

I made the 3D models available for free. The boat was designed by Bruce Potter Bingham sadly passed away recently. This boat is made of ferrocement, a technique now obsolete, but I hope it will be of interest considering the unique characteristics of this small boat, capable of crossing oceans...

You guys are probably gonna hate me for asking this; but, what do you think would be the quickest, cheapest and easiest to build bugout sailboat? I've been looking at techniques such as duct-tape/pvc/sof, a beachcat, from 4.5" pvc tubing; and corrugated alu outrigger canoes with crab-claw...

Hi I imagine a few people here have access to an orc VPP design subscription so it made sense to ask here. I am thinking about buying it to improve/experiment on my boat with new sails sizes and shapes and so see the resulting changes on the polars. They already have my hull form and the polar...

Hello folks, Just a simple question, I have a standard sized small rowboat and have built myself a sailing kit, with rudder, leeboards, mast and sail. Tested it today, sails like a dream, but of course, the upwind capability could be better - it slows down considerably=extremely slow. Of course...

Hi all! I purchased a 1950's 25 foot Raven class sailboat last fall. After a winter of interior work I have flipped the boat and moved on to doing repairs to the hull. The hull is 5 ply of mahogany strips cold molded and of course has 70 years of aging repairs and issues to deal with. I have a...

By small boats I a sort of full displacement, human powered motorsailer, a 50/50 row sail boat, like a Solway Dory sailing canoe or one of Atkins small row/sail skiffs, with the following restrictions: Total displacement at full load: < 500 lbs (227 kg) LoA: 8 > 16' (2.5 > 5 m) Max beam: 2.5 >...

Cheers everyone, trying to get my coefficients defined in Maxsurf for my fin keel sloop. However, I would like to exclude the appendages for this purpose setting the draft as the canoe body's one. But the software only gives a bunch of options that dont include defining it manually. I imported...

I just made off with a "free boat," (no such thing as a free boat.) What kind of boat do I have? Fiberglass over plywood. Sincerely, Trailer Bob
