Hi I am a new member so not to sure how to use a forum. Also a relative newcomer to the sport. I am building a chined yacht from .8 beech ply to replace my 1993 bantocqk bikin,i that through the ravages of time, has a warped hull and keel and rudder that only point in the vague direction they should. As this my first attempt I want to keep it simple and cheap using the bikini as donefor as many fifittings as poss. I wondered if anybody could give me there opinion on a couple of points. What wieght glass should I use to cover the exteriors and to I need to glass the inside or can I just lay strips down the internal seams? Gratefull for any input.
