We drink what's in the tanks. For our six months cruising each winter we manage very well without a watermaker and without resorting, in most cases, to buying water. We only cruise the Bahamas and free RO water is available in certain places. Nassau water will not taste the best sometimes so we use a charcoal filter if we've had to load up there. Our 130 gallon tanks are quite adequate. We shower every day in fresh water but try not to drink too much water preferring beer or rum (with a splash of water).
