Joe I can set you up with a manuel softening system that you can use to wash your boat. What I did at sun harbor is had one at my dock and hooked up the boat next to me to share. Then the two boats next to us got one and we all use same brine tank and we backwash once week or more depending on how much water is used. I can also set you up with water filters for the boat. Iron and white boats don't mix well. Let me know and I can set you up over the down time and you will be ready for April
