Building small sailboats II
Please keep on topic.
The MiniCups were intended to be small cheap sailboats anybody could build. However, they were too heavy due to the use of 1/4" (I used 3/16) ply and were not intended to be glassed so they did not last long. I want a modern version using modern methods yielding a considerably lighter boat that lasts longer. I also made major improvements on the sail and spars so that problem is solved. So, stitch and glue maybe with epoxy saturation of the wood and covered with 4 oz glass? I am worried this might result in a heavier boat because the weight of the fillets relative to the boat size may be too much. Is it worth trying to incorporate more high tech stuff like Corecell or similar foam building materials? |

Why bother when you can buy yourself a brand-new sound little sailboat with a proven track record and suppliers of off-the-shelf parts? http://www.sunfishdirect.com/new_sunfish/ You seem to enjoy "stuff" that is in a constant state of disrepair. I don't. You answered your own question. -- I'm the real Harry, and I post from a Mac, as virtually everyone knows.

Thin layers of wood veneer are laminated around a form with successive layers crossing at an angle to each other, essentially creating your own plywood. Using modern waterproof glues like epoxy, the result is not only very light but quite durable. When I was racing sailboats on Long Island Sound back in the 80's and 90's, one of my fastest competitors was a cold molded boat from the late 60's/early 70's. I believe it is still racing today. 3 layers of 1/16th Okume would create an exceptionally strong hull and no fiberglass would be necessary except perhaps to reinforce areas of high stress. Modern hi tech construction is to create a composite hull with thin skins of carbon/glass fiber over a core of closed cell foam, usually vacuum bagged to minimize the amount of epoxy required, and to ensure tight bonding of the layers. Either way, you could use one of your old boats as the construction form for a new one. I'd also suggest asking the same question in rec.boats.building http://www.google.com/search?hl=en&source=hp&q=Modern+Boat+Building%3A+M aterials+and+Methods+&btnG=Google+Search&aq=f&aqi= &aql=&oq=&gs_rfai= |
