Got a feeling you've hit the nail on the head, I haven't seen a lot of floatplane take-offs but there seems to be a lot more movement of the floats during the roll than I would expect and indeed at that 17-second mark the left float, in particular, seems to be moving a bit more. Certainly seems to be struggling after getting itself on the step and even after it looks to be skipping a lot, from what I understand they're meant to be pretty sturdy buggers but could that skipping have caused it to detach at least partially? Haven't seen anyone mention if it's normal for a no-flap takeoff in a floatplane but from my understanding, it isn't.
