What would you do:You are several days sail away from your home port. The seacock on the sink drain through hull is solidly stuck open. There is not an option of hauling the boat out of the water. The nearest place that has the equipment to do it is your home port.Oh, one more thing, the local water is very cold. Not just "not fun" cold but dangerously cold. Are there any options? "Tricks"? or would you "just keep an eye on it"? (my worry is if the hose should fail at sea, you have one very big problem!)I've thought about de-commissioning the sink and trying to plug the through hull from the outside somehow..... bad idea?
