[QUOTE=mmandley;111004]I would think there is a much different weight in and out of water. As in the water the water is actually helping support the weight and out of the water all the weight is right on the deck.

I agree. The bouyancy provided by the water may allow you to support more weight. How much weight? not sure. I've had 3 teens on my platform (150# x 3 =450) and it seems fine.
