sail

Hello fellow sailors. I continue to build my 16-ft Gary Dierking design Wa'apa outrigger sailing canoe. I am torn on what sail to use on the boat, and thus what rig I need to build. I really don't want to spend over $300 on the sail. The designs recommended in the book will cost well over $500...

Hello! I came up with this idea to minimize the air influence from single mast on the main sail. the idea mainly came from reading this paper. I came up with an idea of an A-type that is basically the best of most worlds, in which its still as convenient as the standart and as performative as a...

Hi, I am designing a sailing scow. I know the theory of CG and CB and metacentric height, and resulting roll period. However, differing distribution of mass for the same CG must have an effect on roll period, right? In the example of my sailing scow, which will have rectangular sections, if...

Hi, I just wanted to confirm the Sailmaking course is already available and open for registration. You can check it here: Sailmaking https://navalapp.com/courses/sailmaking/ Sailmaking is a trade mainly learned through practice and experience. The learning process is often long, and only...

Hi all, I'm a second year physics student hoping to learn some sailboat design. I have a particular interest in multihulls and specifically catamarans, if you are able to recommend books and/or resources to help me learn then I would be very grateful. Thanks. PS. I have seen a few companies...

Please give the image a look and give your input. Not really to scale, just a sketch... Somewhat of a combination of a gaff and junk rig with wishbone boom and battens. Freestanding mast. Thinking of either lazy jacks or some kind of rods sticking up off the boom to collect the sails and...

This design is almost ten years old already; but I fell in love with it right away. It's basically a beach-able houseboat, on a trimaran base, with a bow that's built-up for rougher water. I really like the idea of it; but I'd like to find a way to drive it with sail; so that I don't always...

Hello, I am currently on the search for a ship designer to allow for a first draft of a cargo sailer ship! If you are ambitions and want to take on the challenger, please let me know. And, if you know naval designers in which I can enable in a direct conversation with, let me know as well...

Happy New Year all, I built a boat many years ago and after 25 years, I finally took that mast down to check it and do some modifications. The mast has worked very well, but some of the rigging was second hand when I bought it and it seemed a good point to go through things more thoroughly. As...

Hi, This is my first post so please be easy on me. I have just purchased a sail boat - a 41' Van De Stadt with pockets of rust. The following photos show an area of concern. Q. How would I gain access to this aft corner where there's extensive rust for fire spotting internally ? I've...

Basic shape, Cutter32ft designed by William Garden and 3d model created in Blender

Hi guys, Long time reader, first time poster :) Attached below is an idea of mine for a ‘tweak’ of a design. I really like the concept of Dudley Dix’s sport boat style with a ‘retro’ twist for his Retro 29. It is taken off his Didi 26 design and has a flat hull shape and a deep lifting bulb...

Hey, I got inspired a year ago with this project DIY Styrofoam Catamaran https://www.instructables.com/id/DIY-Styrofoam-Catamaran/. I am thinking of building something similar myself, but better. This one is rather flimsy. I would use it for slow sailing/rowing or having a picnic on water in 2...

I have a 14' Starcraft "tinny" to which I'd like to adapt a Grumman Canoe Sailing rig. The sail area is 42 square feet. I plan to use leeboards instead of centre daggerboard. Steering would be with a 'steering oar' arrangement in order to assist in coming about. I read on another post that...

I am giving away "Stella del mare", amateur build 1984. It's a beloved Pahi 31 - or rather it's plans (scan and copies are left) and French highsea papers "Acte de Francisation" You can entrust the boat to anyone, without a licence, don't need a state inspection and still have European boat...

Plenty of stability from 40" beam. note bow raises to keep out of trouble as speed increases without the crew moving aft. There are two laminate sails 4.7 and 6m.

I built an 8ft plywood sailing dinghy. Now it is time to make a sail. I am looking for plans for a small sail and a lot of them assume that you have done this before. Can anyone recommend plans to make a sail?

I am currently building a foiling offshore racing prototype. We have a mast engineer who is specking the mast. My sailmaker is very busy so I looking for somebody or recombination of software that can calculate headstay loads of various sails using the Righting Moments.

Hello, I have appreciated this forum, especially the thread involving 5monkeys and canracer's repairs of this boat. I am now taking on my own repair of hull #553 which I recently took home. It seems to be in decent shape. I have removed the forward bulkhead. The tabbing of fiberglass tape had...
