newbie buiding a catamaran
hello everybody,
how do you suggest me to build a catamaran of about 3meters long that will be used with remotecontrol for monitoring. i was thinking about a wooden shape covered with some kind of fiberglass ... but i dont know what wood or epoxy or whatever to use. it should be most of all resistant. lightness is not primary.... thank you for suggestions and excuse me for my bad english. matthias |

the remotecontrol part i allready taken care of... plans are ready for servo
control with a smallform motherboard. with resistant i mean it should not break to easy... i would like a solid structure. "Sam" wrote in message om...

I'd only cover with fibreglass for longevity. take a look at the Loonie and Delta on my website (see below) to see what's possible. you have to know how much weight the boat must float and calculate the volume of hull needed to float that weight. thank you for suggestions and excuse me for my bad english. matthias -- ------------------------------------------------------------------------------ William R Watt National Capital FreeNet Ottawa's free community network homepage: www.ncf.ca/~ag384/top.htm warning: non-freenet email must have "notspam" in subject or it's returned |

how thin (i hope it is like that it should be written) can plywood be found?
and if i fave a rather complex shape, is it easy to 'bend' it? what should i use as coating for protection? thanks and have a good evening. matthias "William R. Watt" wrote in message ...

i have a friend that works in repairing old wooden boats, and i talked to
him a few month ago (we live far away from each other) and he was talking about a paint that was i think epoxy based. it was with 2 components, no need of fiberglass, i would have given it a coating better then paint, and also the structure would gain in strength...it was i think expensive but a very light solution. i just cant remember what kind of stuff it was...i am trying to reach my friend...but nada...no answer..mmm... thanks for te information William. matthias "William R.
