When you look at a boat with a watermaker check the onboard water capacity. Many boats are really reducing that number. If the water maker fails it puts you in a bind if you have 60 gallons of tankage. It’s also important for obvious reasons if the boat does not have a water maker installed. I see cats of equal size with huge differences in capacity. I consider 200 gallons a personal minimum on a cat over 45 feet. With that amount of water I need only one stop with zero rationing for 8 people and don’t stop at all if it’s just the family.
