wood is far better because when it gets wet you can always dry it out and when plastic boats start to delaminate wooden ones can be maintained with alot more ease

Yes, but don't forget the class specific issues are very very important!
Obviously a man who's never had to deal with delaminating plywood, or thirty year old wodd boats where the aerolite has gone brittle and is letting go! Wood is still a fine boatbuilding material, and if you are building a boat for the pleasure of working with the materials and seeing the finished object then I prefer it to epoxy/foam. I have a wood boat, a wood decked foam boat and an all foam boat, snd there's no doubt in my mind that the all foam boat is far less hassle to maintain as well as needing less work. Nowadays I would almost always build only consider ply for a quick knock up/throwaway boat to try something out and even then there would be a lot of glass carbon/epoxy in it. |

don't composite boats only need looking after at the end of their lives, whereas a woodeen boat need to be looked after all its life

i have completly restored a boat and it wasnt that hard. however it did take me 3 months but i was 16 at the time so i didnt think i did that bad! plus these days epoxy is far better than it used to be west and sp are just so much stronger. They dont use castermite much now because it goes brittle with age but sp and west altho expencive last longer and hold stronger.

There is a big difference between the resin types used and the effect that they have on a boat life. When the boat flexes both the resin and the fibers strech the problem with Polyester resin boats is that the resin is not quite as stretchy as the glass so as the boat flexes you get micro cracking of the resin. this is largely what makes a boat go soft with age. Epoxy is much better as it can strech futher before failing plus it absorbs much less water than polyester resins and does not smell as bad when curing. Unfortunately it is more expensive.

If it doesn't break it's too heavy; if it does it wasn't built right
