J/30 Class Association Forums J/30 Forum One Design Class Rules Bladder Type Holding Tank

Actually, the empty polyethylene tanks are very light when empty (~15 pounds for 15 Gal tank). A bladder tank of similar capacity is about 6 pounds. Just look at the shipping weights in a Marine catalog for the ballpark comparison. The weight is in the stuff that fills it up! That's comparable to water or ~ 8.4 pounds per gallon.

I don't thing this is a weight issue from a class rules standpoint, but Larry will have to weigh in (pun intended...)

For my money, I want my stuff in a rigid walled polyethylene tank, not some bladder.
