A plywood stitch and glue kayak hull is a full monocoque construction. Exact opposite of a skin on stick kayak, where the strength is in the frame, and skin just covers it.
Lapstrake, it seems to me, is a semi-monocoque construction with most of the strength in the skin?
In general, I wouldn't see an advantage in any of the ways, only interesting and pertinent to applications in certain situations. In my eye, they are all beautiful (boats, planes, and women are elegantly shaped - not necessarily in that order of priority). Lapstrake always reminds me of Vikings' dragon ships - and that means adventure - even if it is setting on the front lawn.

I spent most of my money on airplanes, whiskey, and women - and I'm afraid I just wasted the rest.
