Glass over wood multis are the greatest thing to hit the boating
world since the weighted keel
OK, so maybe I am a bit prejudice on the matter. The pros are, easy to build, easy to work
on, cheaper (in my opinion) to build for the home builder
Cons, Wood rot. Unfortunately, there are LOTS of small inaccessible spaces in a multi hull for rot to happen. Weight. Wood is not light. Glass over wood hulls tend, for the most part, to be heavier, which can be a real issue for multi's.
I admit I have not built or owned a glass multi, only glass over wood, but having owned Fiberglass, wood, and ferro
boats, and done major restoration
to all, this is the easiest hull material I have worked with.
