I will remove the division of Europe to East and West. It is old obsolete Cold War construct. It has no sense to pull Prague east of Vienna. Czech republic and Poland always belonged to Western civilization. Just because they are Slavic countries doesnt mean that they belong to Eastern Europe. — Preceding unsigned comment added by 90.178.145.73 (talk) 11:13, 22 October 2016 (UTC)[reply]

Low stability of Dugouts

I am missing a section on the stability of Dugouts. It has been argued that due to their round hulls, they are very unstable. As a physicist I can clear see this, but I have no references.

A crude analysis of the buoyancy and gravitational responses to perturbation, quickly reveals it as a very unstable construction. Because the center of gravity and the attack point of the buoyancy force, will always be aligned vertical in a round-hulled boat. There will be almost no horizontal force-component to re-stabilze a perturbed logboat. It can be accounted for (somewhat), by carving a flat 'boat-floor' (dont know the technical terms), but not much.

I therefore doubt that round-hulled logboats could carry 8-10+ people across many miles of open ocean. What are the observations of todays indigenous peoples uses of logboats? Do it require a high skill level to manoeuvre? What do they do - if anything - to counterbalance the low stability of a round hull?
