Sea Shell Assembly Suggestions

Temporary construction framework

(For use with full scale driving included in kit)
Your SEA SHELL kit is made up of parts for an assembly framework and a SEA SHELL. Figure 1 and full scale drawing show the framework consisting of two transverse frames A and B, and one longitudinal frame C. SEA SHELL is to be removed from framework which is to be disassembled on completion of hull.

Suggestions for assembling temporary framework:

All frame parts are exact. DO NOT SAW OR PLANE.

Match frame parts to match lines shown on full scale drawing. Secure plywood gussets to frame parts with 3/4" screws. Use 1 1/2" screws in assembling longitudinal frame.

Plywood guests of the transverse frames should face each other when assembled in longitudinal frame (fig. 1)

Frame A should be nearest bow leg of longitudinal frame (fig. 1)

Securely fasten completed framework to a level floor.

Planing inner keel, chines and sides

Suggestions for assembling SEA SHELL:
1. Do not plane any parts except as noted. DO NOT SAW ANY PARTS.
2. Up until the SEA SHELL is removed from the temporary framework all references are made to a boat upside down.  (fig. 1)
3. Put inner keel (fig. 2) in keel slots centering on longitudinal frame (C) matching angles at keel ends. Fasten Temporarily.
4. Locate bow or smaller transom (fig. 2 and fig. 4) so that the tip of the corner where transom meets keel is centered on and 3/8" above the inner keel. Fasten temporarily. Locate stern transom in similar manner 3/16" above inner keel. In centering transoms NOTE that legs are off center. Fasten bow transom to inner keel with one 1 1/2" screw and stern transom to inner keel with two 1 1/2" screws.

5. The sides are furnished slightly longer than required to provide an overlap for trimming after assembly. Allow equal overlaps at all four side-to-transform joints. Fasten sides to transoms with 1" screws (smaller diameter) 1 1/2" apart. Glue joining surfaces. Do not plane transoms at these joints.

6. Install chines (furnished left and right hand) in chine slots (full scale drawing and fig. 2) and fasten to sides using 3/4" screws 2 1/2" apart. Glue joining surfaces. Screws should be 3/4" from upper face of chine to  allow for planing. Screw heads should be in plywood.

7. Plane off tips of corners of transom flush with inner keel.
