re: Went to the boat for a sail..and its Flooded!!!
Almost the same thing hapenned to me last year (2 weeks after getting the boat). I had a leaky raw water hose. Small leak but the pump did not engage for some reason.
I was lucky, I had a deep and large bilge and nothing was flooded but the water was almost at the sole board level (on my boat the bilge runs almost the whole length of the cabin).
