Thanks for the good ideas. Funkster, what is "tube sand"? Does anyone know where you get heavy duty canvas bags} like they use for real sand bags? You know, like you see on the news when the town is about to flood and they're trying to save Main Street. Those can't be very expensive.
Sandy, the reason for the dry weight is that I have a smaller boat, a 94 Malibu Skier closed bow. The fat sacs took up too much floor space. With dry weight I can tuck it away under the bow, under the observers seat, and some on the floor. I will not come close to overweighting and taking on water.
