We had a hard sail on a port tack with rail in water for about 2 hrs.
When we came into port and opened the refrigerator a large amount of water burst out.
Apparently we took on water through the fridge water out let. It was not from melted ice.
So close the seacock for the fridge under the sink.
I would close all seacocks when sailing !
BTW. This trip was part of part 2 of our boat exchange.
