Yes, the area that failed had skinny fillets. I plan to go back and make wider filets with fiberglass tape embedded in them. The crack is hard to see on the inside, but it seems to have migrated into the plywood of the deck, and shows up next to the skinny fillet.

Overall I'm happy with the pygmy kayaks, but it would be nice to have a little more of the secondary materials, wood floor, fiberglass tape, etc. I've been cutting the wood flour with the colidial silica to get more mileage out of the wood flour, which is harder to find locally. I know, make my own from sawdust. Especially adding the hatches and bulkheads, you burn up more tape, wood flour and epoxy, and they assume you have enough left over from the basic kit.

If I was doing it over again, I'd probably spring for a layer of 4 oz fiberglass cloth on the whole underside of the deck, to reinforce deck mountings and the like. I do plan to filet and tape the rest of the hull deck seam through the hatch openings, that should help. Plus trim down the bulkhead and/or use a cardboard template to fit it better.
