well, it was our first 'big boat'-- a 1980 Rhodes 30 foot sloop rig Seafarer , with a v berth, 2 sinks , a head, a v berth, a galley... so excited ! what an upgrade from the old cal 20 ! we bought the Seafarer from our boat neighbor Moe, who'd gone to the 'dark side' w a 40 foot jefferson. our first week end on the new-to-us boat, , the freshwater par -jabsco diaphragm pump wasn't supplying the galley sink too well. so i cleverly opened the top of the huge 20 gallon freshwater tank located under the v berth cushions and observed it to be nearly empty. so i cleverly went on deck, installed the dock's water hose into the deck fill marked 'water' , and started filling. The spouse was lounging below at the dining table, feet up, reading. suddenly i heard a yell, 'stop whatever you're doing, , would you be interested to know you're causing a flood??' ! Moe had disconnected the hose from the deck 'water' fill into the fresh water tank, and neglected to tell us he always filled the tank by installing the hose thru the forward hatch direct into the tank so he could watch the tank fill.. at least the teak and holly floor got very clean, and the bilge pump got a good work out...
