A 16′ scow sailboat for two

WoodenBoat magazine No. 251 (July/August 2016): The 16′ scow “13” is meant to provide the same sporty experience as the ubiquitous Sunfish design, but to carry two or even three adults while doing so. The mandate was for a simple rig — a definition stretched by the designer as he explored this boat’s potential.

The extra-wide beam allows easy movement around the boat. There are hiking straps for a crew of three, plus handholds. When heeled to 20 degrees, “13” presents a shape like that of a catamaran hull to the water, and the angled leeward bilge board becomes nearly vertical.

The freestanding rig is powerful, with sail shape controlled by a wishbone boom. A so-called “snotter” adjusts outhaul tension by changing the position of the forward end of the boom. Two reefs allow sailing in varying conditions.
