Hello all,
I'm building a 10' tunnelhull and need to add some floatation (for my own
peace of mind) in the aft section soon. I have a question concerning the
weight and ease of use of Styrofoam blocks vs. a pourable, 2 part type. It's
a
small boat, so, I could easily cut and form blocks of Styro to fit, but I'd
have to find some way of gluing into place, or, would I be better off using
a pourable type? I'm convinced the Styro is much lighter but not as easy to
make fit snuggly into place.
How about using Great Stuff from Dow, spray it in in small layers/quantities
to allow for a complete cure before adding more?

Anyone have suggestions? What's easier? What's more worth it? Any pourable
Mfgr's suggestions?
I'm a newby to boat construction but NOT to woodworking.

Thanks in advance
Don
