12 Foot Catboat

12 Foot Catboat
Designed by Edson Schock - Circa 1940's

Follow me as I build a 12 foot catboat from plywood and pine. The boat was designed by Edson Schock in the 1940's. This is a project born of a desire to have another boat to sail here in Puerto Rico that will stand-up to the Trade winds. The sail plan will be changed to a gaff rigged sail. All the lumber is locally bought and pine will be substituted for oak, which is not readily available here. Marine plywood will be used.

Floors and Spreaders

I began to glue and nail the floors to the frames yesterday and finished them this morning. Stacked against themselves, you can get an idea of what the contour of the boat will look like.



With the floors all installed, it was time to install the spreader. The spreader is a 1-1/2" x 1-1/2" piece that gets installed where the frame gets set onto the "foundation" or building cradle. It adds support to the frame during construction and locates the frame at the correct height on the foundation.

The building cradle will be a rectangle 14 feet long by 4 feet wide. Squared and leveled, the cradle will support the boat as it gets built. It is one of the next things that gets built.

Back to the spreaders.

I cut each spreader at least 4 feey wide and more as the frames widen. I think the widest was around 78 inches.

I pilot each spreader then attach it in the correct position with decking screws.





Every screw, no matter its function, gets waxed before screwing it in to lubricate it.

The finished products:





Tomorrow, I will either start the cradle or cut the insets for the long wood stringers that will help hold the frames in place.

  1. hi Steve,

    I didn't know you could do all this engineering,
    for goodness sake! Amazing! If I was there, I could help by petting the cat, smoking, reminiscing about 1967-1968 at Ramey, etc., amen, ad infinitum.

    What about finish? Have you ever done a Sunburst finish on a boat? (Sunburst as in Fender Sunburst).

    regards,
    Josie
