From Hobie's own site:
http://www.hobiecat.com/support/tech/delam.htmlThis method has been tried and true. The only thing I would actually do differently, is once you've filled the layer with epoxy, then dips some drywall screws in veggie oil, and sink two or three of them completely through both layers. This will pull the bottom fiberglass layer back to the top. Once the epoxy has kicked, remove the screws gently, and plug the holes.
The repair that Bill mentions, is the kind that I did on my boat, except I actually laid some marine grade laminated hardwood up under the deck and then used a buttload of low density filler and some layers of glass to fix the deck. Its rock solid, but I wouldn't want to undertake that project without epoxy/fiberglass experience when the epoxy injection will do the same thing for you.
