I have a very nice mold for a 17 foot planing dinghy that I have been trying to sell (cheap). No takers so far and I really want to free up space in my shop. Can anyone recommend a Boat Building School or similar Educational Program that would benefit from the donation of a mold they could use...

I have the hull and CB structure Molds for the International 505, 17ft planing dinghy. This design was by Pegasus Racing, 3 hulls were pulled from this mold that I am aware of. Two boats were for recreational use and one hull for racing was made of carbon and was officially measured. The mold...

I'm interested in making some parts using CNC filament winding, mostly utility kinds of things that aren't subject to the heaviest loads like vertical supports for hard-tops (lightweight ones, lol). Eventually I'd like to be able to make spinnaker poles, life-line stanchions, etc; those of...

Is there a method for vac infusion/wet lay-up bagging to laminate both sides of a Nomex Honeycomb panel with a thin layer of fiberglass/carbon? I ask because I have only seen the process done with pre-preg. I am assuming that if you tried to make a panel by vac-inufsion or vac-bagging a wet...

I have become the Steward of a mold for the International 505 racing dinghy. I'm not going into business for myself, but I would like to pull one hull for my own enjoyment in sailing and in practicing the craft. I have the shop space and tools (mostly) for vac infusion. I don't have an oven...

I don't have my own CNC router and not much experience with larger format machines (4 x 8 ft cutting range). I have access to some really good machines to use or I can get my own, the prices are pretty fair for machines with higher quality and capability these days... Anyway, my question is...

I have the total materials list (but not the specific lay-up schedule) for a boat design I like listed in weights of cloth in Gsm, the width of roll, and total weight in KG for each type of cloth. It is mostly E-Glass as well as come uni-directional carbon and tapes for reinforcement. I want...

Looking at a 1994 Dufour F-39 (maybe the same as the Frers 39, both designed by German Frers) Curious if anyone is familiar with general build specifications on these hulls done in the mid 90's, I can't find any solid info on some of the specs I would like to know; Keel; I'm assuming lead but...

Hi everyone... I've been absent on the forum the last 18 months. Finishing grad school and restoring my little 'vintage' swing-keel sloop, both should be done in June. I've learned a ton from this forum and done further reading to understand design more, so thanks to the resident experts here...

I have been doing a great deal of book reading and forum research on the pros and cons of ketch rigs as well as other multiple mast rigs. Because of my love for classic lines and old wooden boats I've come to greatly admire multiple mast rigs in general, but particularly the ketch rig. So as...

I've been bouncing around an idea in my head for years of a build method that is a hybrid between stitch & glue and foam core composite. The short version is to take a supply of foam core sheets in 4x 8 feet and laminate them on one or both sides with the desired cloth and vac bag with epoxy...

I have been toying with the idea of building a carbon mast using pre-fab oval tubes of the same general dimensions as the original aluminum spar. Now I finally have my own boat to work with, a 1981 Catalina 22, so I can contemplate 'actual' rather than theorectical dimensions. Obviously this...

I bought a used galvanized tandem axle boat trailer and I will need to add brakes to be 'legal', although I know no one will ever check, but safety first. The boat on the trailer is a very light (under 2000 lb) sailboat, and I've already had plenty of people say you don't need trailer brakes...

Below is a pic of Venture 2-22 (same as Macgregor 22) that is for sale in my area. This boat is my 2nd choice for a cheap Trailer Sailer, still waiting on word from another seller of a CAL 21. I went and checked out this boat the other day. Owner wants too much money for as many problems...

I'm wondering how lifting keel boats sit on blocks or on a trailer. As I understand it on fixed keel boats most of the wieght rests on the keel while the boat stands provide 4 to 6 points of stability, not really supporting actual wieght. So how does this work for a lifting keel design? I...

I'm certainly no "Doomsday Prepper", but sometimes my mind wanders off to the question of what type of vessel I would build for long term survival at sea after an Apocalypse scenario. One of my favorite TV shows is "The Walking Dead" and I am also a fan of the Zombie Apocalypse movie genre so...
