The "Building Bug" has bit me !!!! It's been a few years since I've really built anything. The last boat I built was a Hot Shot 45 about 4 years ago. I've mostly be into RTRs, and fibergalss hull kits, easy stuff. I've just about finished framing a 36''Dumas Eagle Hydro wood kit. I've replaced some of the wood with aircraft ply, and cut holes in the framing to lighten it up. My question is: Is there anything besides thinned epoxy to seal the inside with ?? Something new, easyer, cheaper, or LIGHTER ?? I plan to use thinned epoxy on the outside, but is fiberglass reinforcement really needed on the outside?? This will be just a play boat spending most of is time as a shelf queen, but I'd still like to build it the best, stongest, lightest way that I can. A good friend bought a built Dumas Miller American off of eBay, and this damn thing weighs a ton !! It's what I'm trying to avoid. Engine will be an OS 46. Any other tips, or suggestions are welcome. I've also been having a Miss Circus Circus (with fiberglass cowl), and a Miss Unlimited that I plan to build. Thanks for any input !!!
