Hold Bulkheads in position by temporarily toenailing each end to Deck with 1" brads.  
Be sure to fasten top edge of Bulkheads to Deck as noted in Illus. B.  
Top edge of Bulkheads has only one V-cut as indicated on Patterns.

Note  Illus. D (Side View).
Measure down 2 1/4" at Bulkhead No. 2; 1 5/8" at Bulkhead No. 1 and 3/4" at No. 9. 
Mark off curved form by these points and saw both Sides to same shape.
Clamp Sides in position again to be sure they fit tight against ends of Bulkheads and other Framing.

Apply glue to all connecting surfaces between Framing, Bulkheads, Sides and Deck and screw Side to 9 and 10 with 1 1/2" No. 10 screws.

Give entire Surfboard a coat of Firzite or equal.
Sandpaper smooth and finish with good quality marine enamel.
Follow manufacturer's directions for applying enamel used.

A piece of canvas can be cut and glued to Deck to provide a non-slippery surface.

Leave Deck Plate open when Surfboard is not in use.
This will permit inside of board to dry and will prevent dry rot.

NOTE: If plywood is not available in 10 ft. panels, you can splice smaller panels as shown in Illus. E.
Splice with a 6" wide Strip of 1/4" Plywood.
Cut strip length needed to fit between Sides 12.
Glue and clamp strip to plywood.
Center of joint should be over center of Bulk­head as indicated.
Cut this Bulkhead 1/4" less in width before glueing to Deck in order to accomodate splice.
Splices in top and bottom panels should not occur at the same Bulkhead.
One 4 ft. x 8 ft. panel and one 3 ft. x 4 ft. panel is ample for Deck, Bottom and Splices if 10 ft. panel is not available.
