8. Center outer keel on inner keel (fig. 3) and fasten temporarily. Draw two lines full length of SEA SHELL at the intersection of the inner and outer keel. Remove outer keel for ease of planning.

9. To make ready for bottom installation plane alternately corner of inner keel and outside corner of chine and side. Plane to pencil line on inner keel and to inside edge of chine using as a guide a straight edge which must touch the planed surfaces at all points when moved along the boat parallel to the transoms. DO NOT PLANE off either pencil line or inside edge of chine.

10. Fasten outer keel in place using 1" screws (larger diameter) 8" apart. Glue joining surfaces.

11. The bottoms are furnished slightly larger than required to provide an overlap for trimming after assembly. Bevel edge of bottom at outer keel (fig. 3) and fasten bottom in place allowing equal overlaps at bottom-to-transom joints. In fastening bottoms use 3/4" screws 2 1/2" apart along inner keel and chine, and 1" screws (smaller diameter) 1 1/2" apart along both transoms. Glue joining surfaces.

12. Fasten skeg in place (fig. 7) with two screws. Glue joining surfaces.

13. Remove SEA SHELL from form. Disassemble frames. SAVE SCREWS.

14. Fasten skeg from inside with three screws (fig. 7).

15. Fasten seat blocks (fig. 2) 5 3/4" below rail using three 3/4" screws into each block with screw heads in plywood. Glue joining surfaces. 

16. Install web (fig. 2) using six 3/4" screws with heads in plywood. Install post with 1" screw (large diameter) into web.

17. Fasten seats in place using two 1 1/2" screws at each end and one 1 1/2" screw into post in center seat only.

18. Fasten each of four breasthooks (fig. 2 and fig. 3) using two 1 1/2" screws through transoms and two 3/4" screws through sides with screw heads in plywood.

19. Fasten rails in place with two 1 1/2" screws at each end, one into breasthook and one into transom. Fasten rail with 3/4" screws 4" apart with screw heads in plywood. Glue joining surfaces.

20. Fasten oarlock sockets (fig. 2) with 1" (larger diameter) screws.

21. Finish all edges flush prior to sanding and painting. 

Note: Use No. 28 drill for smaller diameter screws and No. 10 drill for larger diameter screws. Do not use outboard motor over 2HP without additional reinforcement. The use of a countersink in screw holes will allow screw heads to be set flush with plywood.
