There's a world of fun for those who "ride in with the waves" or "paddle under the sun" with this easy-to-build 10ft Surfboard.
No special skill is required with the Full Size Frame Patterns and Simplified Directions.
Pattern also explains how to install special "sea-scope" window for viewing marine life and spear fishing.

Before starting work, read Directions through carefully and note location of each part when mentioned.
Study the Full Size Patterns and the Assembly Illustrations as they are referred to.
For greater strength and rigidity, use waterproof glue at all joints.
Dip screws and brads in glue before driving.

Starting with Bulkhead No. 1, glue all Bulkheads to Deck.
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.
Glue and toenail Framing 9, 10, 11 to Deck.
Turn Panel over and nail through Deck into all Bulkheads and Framing with 1" No. 16 brads spaced about 3 inches apart.

For SIDES No. 12, clamp two 10 ft. lengths of 1/2 x 3 in position to Bow 9 and Stern 10 as shown in Illus. C and D.
Clamp Side 12 so it fits snugly into notch in No. 9, as indicated, Side 12 is cut flush with No. 10.
With pencil, mark location of each Bulkhead-on Side 12.

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.

To form curved bottom, plane edges at Bulkheads 1 and 2 and face of Bow Board 9 so that Bottom Panel fits flat against them.

Give entire inside of Surfboard (except exposed edge of Sides, Bulkheads and Framing) a coat of White Firzite*.

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.
