Building A Sailing Pram
Building A 7 ft. 10 In. Sailing Pram(or Picnic Table Boat Building) Page 2 of 3.
Probably the most time consuming and difficult part of this build was constructing and installing the center board. The plans do not show dimensions for the center board trunk on the details. In the Bill of Materials it lists the parts as 2 pieces 12 by 16 inches. So I built it ahead of time only to discover when I installed the mid seat that the height of the center board trunk could not be more than about 9 inches (not 12"). I had to cut three inches off the top. See Fig. 11. Fig. 12 Shows the trunk from the rear, with the bow seat ahead.
The clamps and dowels were used to align the trunk with the centerline of the boat and the slot in the bottom. What you can't see here is that the cap on the trunk extends under the midseat about 8 inches. Eventually I will put two screws through the seat to lock the seat and trunk together.
