so far i have not found any problem with sailing with doors ajar--- there are hooks to maintain the open status and seas haven't come near the cockpit-- over the waist, yes, but th scuppers deal well with that-- so i sail with my doors open. seas have to come a far distance to hit my doors and enter boat.
there are also latches
and bolts to make sure the doors are lockable from inside.
one door has an overlap for making seal for when closed--i wouldnt dream of having anyhting on this boat maintain decency in a knock down--i prevent that when at all possible. aint wanting to sink.
