Hi
I have large valves attached to each of my cockpit drain hose too and
I have sat in the cabin looking at them thinking what they might be
used for. (When you might want to shut them.) I can not see how they
can protect from though-the-hull failures. If the drain
through-the-hull fails, it will be of concern if it is outside the
hosing system--in which case shutting the the valve would be
pointless. If the cockpit is awash with a wave, there is no need to
close the valve then either. The only reason I could see to close the
valve would be to take a bath in the cockpit, but I have better
places to that.
Someone spent some time and some money to install these things.
I do not under stand why. Could someone explain this?
