A) you have a nice boat capable of ocean passages,
B) she has a cockpit that WILL nearly sink the boat, if flooded,
C) if you sail enough, the above scenario WILL happen,
We are sailing a similar boat. Our cockpit is too voluminous (offshore) too. We got (very badly) pooped once. It took about 5 minutes for two 1+'' drains (plus one very frightened skipper
with a bucket) to drain the cockpit. This may, in some situations, be too long to assure the boat is safe. We were lucky.
I think drains aft may be mistake in some designs - they sometimes tend to flood the cockpit when the boat gains speed. I think drains belong in the forward corners. I am not certain they have to cross - they do not cross here and we never have water coming into the cockpit when sailing.
1) limit the volume,
2) limit the volume,
3) see above,
4) with limited cockpit volume, make sure you have two 1+'' drains (IMHO forward corners).
Too bad the floor is this low. As it is, we can only try to improve on what the designers designed for less troubled waters.
