Hi I have 87' Hunter 23. When I bought her she had her water tank and sink taken out. I was thinking about putting one back in. I feel it might be helpful when I overnight to was off hand, dishes, and whatnot. Althought I feel not wise to drink from. I havent made up my mind yet and was wondering if it was worth the hassel. It might just put MORE weight on the side already, alone with battery and engine! Well does anyone have any suggestions or experiences? Thanks
