glass fibre absorbs water which reacts with some chemicals that can result
in blisters, timber swells with water absorbtion .. can rot... be attacked
by worms, steel rusts and aluminium can corrode quickly, ferro cement ...
porous..corrosion prone....
So what is best to use?
It would seem that no material - even steel or aluminium is pure and so can
have problems, so it all comes down to cost of ownership over time.....but
no method guarantees the hull will be in good condition when you want to
sell in 5 - 10 years time. So is the best solution to hire ?
