The Siskiwit Bay SOF is a multi-chined version of the original Siskiwit Bay cedar strip boat. It’s a great modern British-style sea kayak that a builder can scale down to suit his size. These free kayak plans are for builders desiring a skin-on-frame version of the boat built in Yost-style. For stitch and glue plywood builders, the Siskiwit Bay MC is also available. The plans come as full-sized drawings that you can print.
Note: The sheerline and design features sweeping curves that might challenge first-time Yost-style builders. If you haven’t built a Yost-style SOF before, this might not be the best option.
The basic process of a wooden framed Yost-style SOF is to cut out the six wooden frames, shape them to accept stringers. Glue or nail it all together and then skin it with ballistic nylon. You then coat the nylon with a waterproof coating.

The linesplan gives you an overview of what the finished kayak will look like. This boat has some rocker, which makes it easy to turn. The flare makes the secondary stability feel solid, so it’s easy to hold on edge for quicker turns. The stern stem is harder than the cedar strip version which helps with tracking, because you can’t add a skeg to this boat. The cockpit, which isn’t shown runs between station three and four. It’s 30 inches long.
Note: This chart shows that the SOF isn’t as stable as the Bay or LV.
