The Siskiwit Bay is all-around, fast, mid-sized, British-style, touring kayak. This solid boat suits a medium to heavy paddler looking for good initial stability and lots of secondary stability. As the water gets rougher, this kayak feels more stable. It’s a fast design slightly more efficient than most British kayaks in its class.
- Length: 17 feet
- Width: 21 inches
- Volume: 12.325 cubic feet
Displacement and Sizing
This kayak was designed with a five inch waterline to carry: a boat built to 50 pounds, a 200 pound paddler, and 50-pound load. It accommodates paddlers ranging in weight from 140lbs (4.25″ waterline) to 240lbs (just under 6″ waterline). It can carry more than 50 pounds of gear, but why would you? See the Nessmuking articles.
The deck height 48″ forward the back of the cockpit is 11″ high, which will handle U.S. size 11+ feet vertically. The rear coaming height is 8.5″ with a recess and the front height is 12.75″.
If you want a more sporty sea kayak with less volume, consider the Siskiwit LV sea kayak plans.
Ideally you want the longitudinal center of buoyancy of 7.903 from the stern to line up with your center of buoyancy. Or you can put the coaming of the cockpit 5 inches behind the longitudinal center of buoyancy.
These are the John Winter/KAPER numbers using Sea Kayaker Magazines stipulations.
