7m hull composition

[Bigtalljv]

I know there has been some discussion about how the various 7m hulls are built, foam or balsa core. Well, my hull, the old Rib-P appears to be solid fiberglass. 5/8" of solid glass. I cut a hole for a new transducer.

My H640 hull is the same. Hull solid glass and the deck is cored.

Willard console composition.

Yep, my deck, console, and transom are made from at least two different foams. That foam and then a much more dense foam in the transom.

Ya, I wonder what the blue layer is?

[cgoing]

Probably a bonding putty or adhesive to hold the foam core in place during the manufacturing process.

The blue is a bonding agent that hold it all together and fills all the voids, its usually put on with a trawl, them put under presure as the resin is infused into the hull/cap.

I have all the layup specs somewhere.
