Maybe I don't understand... How does filling a paddle with foam or having the paddle be made out of wood make it more bouyant? Foam can decrease the need for higher density structural materials. But just filling air with foam or wood makes it less bouyant not more. Greenlanders typically have a higher volume, hence more buoyancy. If you made one out of carbon and left it hollow, it would be more bouyant than the same paddle in wood. live long and paddle, albert > I would question the amount of buoyant force from a high-aspect (I hope this > is the Greenland version which is what I am talking about) paddle.
