during the rainy season we could do it all the time. We carried 350 gallons and could go a month or more taking showers every day. When we could see rain on the horizon we'd rturn on the radar and get ready. After the first shower we'd plug the holes and the tanks would fill. It was a wonderful experience and rainwater is great.
Our boat caught water great with the fills at the lowest part of the deck. We'd sit below watching it fill and giggle. Never waited for watermaker parts as so many others were doing.
