Hi Group,I'm not presently a Hunter owner but am very interested in a 260. I live and will sail on the Mississippi river which is a long way from clean. With the fluctuating water levels and low water levels generally I think a water ballast boat would work best. My question is - can one fill the ballast tanks with clean fresh water from a hose before launching. Is the extra weight a problem for the boat before it is bouyant. And, if the ballast tank is filled with clean water can it remain in the tanks for the season? The other option is filling the tanks with Miss. water - that's starting out badly I would think.From the Muddy Miss.Jim
