The water supply is an interesting question indeed. To me it is of similar importance as the question of navigation. Even if ancient proto-polynesians had a hunch that there was land somewhere, they must have known about the need of fresh water. And on top of that they either did not want to ever go home or they must have had an idea about how to log their route. Fascinating stuff.
