Description: The Siskiwit Bay MC is all-around fast mid-sized British-style touring kayak designed for plywood building. This kayak suits a medium to heavy paddler looking for good initial stability and with increased flare above the waterline 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. Designed by Bryan Hansel.
Experimental: Since the Siskiwit Bay plans became available on the Internet, I’ve received requests for a plywood version of the kayak. The SB was originally designed as a multi-chined boat for plywood building using the excellent HULLS software. I’ve taken the original file and used Delftship Pro to clean it up and fair the lines. From this cleaned up original file, I’ve produced a dxf and a text file of offsets. These are available for plywood builders. A deck is included, but it is experimental.
Hydrostatics: Generated for 295 pounds, which is the number used for Sea Kayaker Magazine’s reviews. (195 pound paddler + 45 pound kayak + 55 pounds of gear).
Design Name: Siskiwit Bay MC
- Design length: 17 feet
- Design beam: 1.757 feet
- Design draft: 0.417 feet
- Length on waterline: 14.908 feet
- Beam on waterline: 1.649 feet

KAPER: KAPER is a resistance program used by Sea Kayaker Magazine for their reviews. SK uses a weight of 250 pounds plus the weight of the kayak to calculate the resistance. It is provided here at the same weight for comparative purposes.
- 1 knot – 0.24
- 2 knots – 0.87
- 3 knots – 1.81
- 4 knots – 3.35
- 4.5 knots – 4.66
- 5 knots – 6.87
Note: This chart shows that the MC isn’t as stable as the Bay or LV.
Drawings: Three formats are available. DXF, PDF of the DXF printed over ten ARCH E sheets at full size and offsets in text.

Yost-style Skin-on-Frame Plans
The three drawings provide the basis for a Yost-style skin-on-frame. I’ve gotten many requests for this, so someone better build it! :)
