Not sure about that... The label doesn't specify if the weight is water, lead, or people. If the boat swamps, there are vastly different requirements for each. A good example are wake boats. They are WELL over their sticker weight when loaded down with ballast, even in the factory setups. Important part is that it is water weight, so it is neutrally bouyant if you swamp. Lead (or a heavy engine block) isn't, that will take you down. People on the other hand are relatively neutral, but it would be nice to have a little bouyancy to hold onto the floating hull.
