Glen-l boat jackknife boat kit.
Ribs and instructions. I also have the stringers, purchased separately.
You will need 10 sheets of plywood (I think) and epoxy.
The Jackknife and Celerity are the same boat, different deck.
The plans sell for $600. They no longer sell the kit, but was $1700.
You will need good woodworking skills and space to layout.
