Epona, have you read at all about the pools of fresh water that form in the caribean? Massive amounts of fresh water come up from underground artesian wells forming huge pockets of fresh water that are a navagation hazard for ships and subs. Fresh waters buoyancy is far lower than saltwater and if your balast is too great your ship will just sink. Neat stuff
