I left the crew on Morgan OI41 hull # 6 to fill the water tanks while I wandered ashore to some something really important with paperwork or something.
Came back half an hour later and crew had the hose in the same fill.
Go below and paddle around in fresh water.
Look in engine space under cockpit -- water spewing out of poly tank. Luckily, the split was at the top . . .
It's entirely possible a seam or something has weakened . . . (that boat was less than a year old at the time).
