皮划艇

三人皮划艇
This is a replica of the U.S. National Museum of Natural History's 398278, collected by Captain Michael A. Healy of the U.S. Revenue Service CutterCorwin in 1885. The kayak is 23'2" long, 26-5/8" wide, and 10-1/2" depth-to-sheer. Despite its great size, it maintains finer length-to-width proportions than some 20th century Unangan 1-hole kayaks, and can of course hold three paddlers.

Note the shallow bow and generous rocker. At the front of the cockpit (not including the coaming), the depth overall is 12-7/8", and it is even deeper behind the cockpit.

The following is a photo-journal of the construction process. Construction began in January of 2009.

An adze is the perfect tool for chamferring down the deck beam's ends into suitable tenons.

Next step is to drill and chisel the rib mortises. Note the drilled-but-not-yet-chiseled
rib mortise on the upper right.

Before inserting the ribs, I stanchion out the keelson so the proper depths are
set. I bend the ribs under the keelson.

White Oak + Steam= Bent ribs! All 20 in place within an hour. The project
now moves from a taper-ended ladder form to an entity of depth and volume.

With the ribs in place, it is now time to make the keelson ends. These pieces join the
keelson to the gunwale ends, and will be scarfed onto the keelson ends. This image
shows the laying out of the proper shape of the stern keelson end.

This is the stern keelson end in place. I had to inset a small cross-piece in order to
hold the keelson end in place (to prevent it from sliding forward).
