Holy crap, you're the Dilworth guy with the website! I've been to your site many times and have found it such a valuable resource. Thanks so much for making your restoration public.

:: Drilling lots of holes and filling them with thickened
:: epoxy did the trick for me. Epoxy might provide more
:: rigidity than foam.
::
:: You can see the holes here

:: :: I'm rather sure my deck core is rotten. I know that the
:: :: best way of fixing this is to cut the deck skin off to
:: :: remove rotten core, replace the rotten core with fresh
:: :: wood, then re-attach the deck skin. That sounds like way
:: :: too much work for a boat that I got off of craigslist
:: :: for $1200, and honestly, it doesn't sound very
:: :: necessary.
:: ::
:: :: I know a lot of people think they can put unthickened
:: :: epoxy into holes drilled into the deck, but because
:: :: epoxy runs all over, I've heard this isn't very
:: :: effective.

:: :: What if I pumped expanding foam from TAP Plastics or the
:: :: aerosol foam insulation from Home Depot into a grid of
:: :: holes drilled into the deck skin? Once each hole is
:: :: filled, I can then fiberglass over the holes. What's
:: :: wrong with that? If such foam is too weak, what about
:: :: epoxy thickened with microspheres? Sounds like it makes
:: :: sense, but evidently nobody on the interwebs has done
:: :: this and posted about it, so I'm wary of trying to do it
:: :: myself.
