St Michaels Sailing Scow

THE BAY'S ODDEST ONE-DESIGN

By Craig O'Donnell.

 

 

 

 



This boat is 12 feet long, and it caught my eye the first time I saw it in the Small Craft Building at CBMM. Although it's pictured in A Heritage in Wood the plans (on two sheets of typing paper) were hiding in the Library files.
So I got a copy of the plans and built a model 1/3 real size. Next I'd like to build one full-size, using plywood. Since I'd be the entire one-design fleet at that point, I'd change the sail plan to a sprit-boom with club and use a leeboard so that there is sprawling space in the cockpit.

 

And there you have it. Click on the thumbnails below to see the plans as large GIF files suitable for building from; it's only a scow after all.
