Re: Life Span of a Boat

Rough guestimate:

that being something like 12m boat for about 50 square metres of fibreglass, at say 8mm thickness that would be roughly 100 gallons of rasin and 50 square metres of glass per layer. probably you get a better price when buying those amounts than when you buy 1/4th gallon

(so those 25k should be more than plenty enough actually)

No, but I know that it depends on the technique. If vacuum infusion and epoxy resins are used you use a lot less material and that's why the boats made that way are lighter.

Re: Life Span of a Boat

I think the hardest part of laying your own hull up would be knowing where to lay it on extra thick and which areas get more glass.

The good news is.. for more money, you could always go CF. even if you don't vacuum bag it, it would still be stronger than FG

I was thinking it might be easier to find a company that can sell only a bare hull/deck kit and finish it out. I haven't found many places that do hull's only.

Re: Life Span of a Boat

if you are going to do that.. why not just buy a really shabby boat that still has a decent hull/deck and strip and redo it how you want?

Exactly - when I bought my complete & floating Columbia 43 (that "demonstrated a high degree of deferred maintenance") a VERY similar bare hull moulding (no deck) from a local manufacturer would have cost 4X as much. Also, that was 10 years ago, before the big drop in used boat prices.

Building from a bare hull is virtually certain to be the most expensive way you can acquire a boat and it will take a BIG chunk out of your life, frequently including your wife and family.

Nowadays it makes no sense - buy something close with good bones and customize it.

I like looking at his main site at the project logs. I found his site from looking at certain models of boats and he just happened to restore one. Very good photo log of his work.

Re: Life Span of a Boat

he took away my fear of rotted decks. I can do glassfibre work.. I had no idea how easy it was to cut off the upper layer, chipout/cleanout the old balsa, and replace

It's simple, not easy. I spent last summer doing patch repairs of the deck on my old 43'. Not much more complicated than making peanut butter sandwiches but I sweated off 30 unmissed Lbs doing it. As long as you are prepared to tackle a fairly big job there is nothing to fear about it.

I found stripping the bottom to the gelcoat, fairing and epoxy coating it to be as big a job and far harder due to having to work overhand.
