Increasingly popular home boatbuilding material - light weight, maintenance free, less easily damaged and more easily repaired.
The centerboard should be faired as shown on the pattern sheet (similar to the rudder as shown below).
Cut a hole to match the steel plate approx 3″ from bottom and sides.
Optionally, the centerboard weight may be a lead-filled hole approximately 30 square inches in size as shown above.

The steel plate will be bonded in the hole in the center layer of plywood. If this is done, it will be necessary to groove the inside of the cut-out area so the lead will not fall out. A swivel block is mounted to the forward trunk upright near underside of the deck. The line is lead through the centerboard sheave and up through the swivel block mounted on the forward trunk upright, and up to the cockpit where it can be secured to a jam cleat mounted on the aft area of the centerboard trunk.

This can be done by drilling a hole through the trunk sides and the centerboard near the top and inserting a brass pin on a chain that can be removed when the board is lowered.
