I agree with you, stickbow, about the Greenland kayak being a true sea kayak. But consider the fact that they were built with only materials that could be scavenged is those isolated areas: scraps of driftwood, bone, sinew, animal skin, etc. Their kayaks might have been VERY different in design if the Greenlanders had access to all the materials we have today. Seeing your handle, stickbow, reminds me of something I read in one of the Traditional Bowyers Bibles. Hunter/gatherer people that used bows tended to stop experimenting on design when they found something that worked. If it did the job and the insufficiencies could be accepted, the design lived on. Not necessarily the "perfect" design, but one that allowed survival- the true test. If a Greenlander went out for seal and came back alive with a seal- bingo!
