Are you going to use a 'seal coat' of epoxy on the wood before glassing?

Yes. There is no other practical way to avoid leaks. Since the hull won't be inside a bag (I want to keep it on the form) this is crucial.


Vacuum infusion or regular wet layup?

wet layup. I don't have the workshop setup for infusion and I don't think it would make much of a difference anyway. Will infuse some smaller parts though, just to get some more experience.


I've found that some areas of wood absorb epoxy more readily - perhaps because of the turn of the grain along the strip length, so avoiding 'dry' areas may be tricky with vacuum. Not a problem with all-glass boats - molds and gelcoat don't absorb resin!

yes that's due to grain direction and varying density. the seal coat should eliminate that issue.

Are you going to use a special resin (ProSet??sp) or one of the 'standard' boatbuilding resins? I've done a bit of vacuum work with small jobs and regular epoxy and I tend to feel the working time 'closing in' if there are any problems with the bag or setup. (Yeah, I know...practice, practice, practice... ;-) )

Resin is an issue here in Montreal, Canada. I decided to give S3 clear coat a shot but it's only second choice. I'm originally from Germany where I fell in love with Sicomin resins. System three doesn't come close to that but it's pretty much the only affordable alternative. I know I could order stuff from the States but shipping rates in and to Canada are outrageous (usually around 10-20x of european shipping rates!).

I know what you mean with the time closing in on you. There's nothing as stressful as a laminating or glueing job - I hate them. Clear Coat has a reasonable working time of around 60 minutes and a low viscosity.
