IF it was your mass, you never would have gotten across in the first place -- that wasn't variable.

This kind of kayak has a molded prow which sometimes gets opened up when the kayak gets stood up on end for loading into a trailer or on a car-top. Check the tip of the prow. Otherwise, mebbe put it up on a pair of sawhorses and fill it with water and reverse-engineer the leak that way.
