Hey guys,

So i have removed the decks, have started to replace a few of the foam bulkheads, and have also added a couple more. Although before I fiberglass the new foam bulkheads in, I just want to confirm that I purchased the right (or wrong) type of foam... I have used 40mm SL grade EPS foam sheet(Expanded Polystyrene), but further research has given me that sinking feeling (no pun intended) that I should have used XPS (Extruded Polystyrene)instead, as this is 'closed cell' and has a resistance to absorbing water. Is this correct? It shouldn't be too hard to re-cut the bulkheads from new foam, but I have no idea where to purchase this... Any suggestions?

I fixed the starboard bulkhead with an epoxy glue fillet (this epoxy stuff is really amazing). Next move once I have taped the foam bulkheads in will be to complete the ply I-Beam supports.

Cheers,
Andrew
