Here's an update for the presentation Saturday night by Bob Holtzman;
Building every kind of canoe … in 10,000 years or less Bob Holtzman
Throughout history and prehistory, canoes have been built in seven fundamentally different ways: dugout, plank-on-frame, sewn plank, skin-on-frame, bark, basket, and balloon. These different building approaches have yielded canoe types of such diversity that we question whether “canoe” even signifies a definable boat type – a notion that will be addressed in a preamble. We will survey all the basic methods of canoe construction and attempt to show how each method evolved from its indigenous, prehistoric roots into a vast variety of historic canoe types, including every type that exists in the present. Bob Holtzman writes the blog Indigenous Boats (indigenousboats.com). He works as an editor and writer and is president of Mythic Gear (mythicdrysuits.com), a drysuit manufacturer in Rockport, Maine.
