( From recent rec.boats NG post )

To build boat hulls ( 30 - 50 feet length cargo /fishing/
displacement
work boats) in plywood which resins are recommended to bond the
plies/veneers of (Gurjan) plywood together...

Polyurethene, epoxy, resorcinol, vinyl ester or phenol formaldehyde?

What are the costs and availability? Is a hot water boil test
adequate? What is the needed test spec?

These need to withstand salt water immersion for many years without
degradation. Also, which marine grades can be used for outside
personnel accomodation ( shelter on deck/ bridge or on wharf ) and
which for deep seawater immersible hulls?

TIA
