I’ve often wondered if that configuration is a good or bad idea. Seems to me that the cockpit may not drain as well when heeled over a lot because the thru-hull on the other side will be higher. Any other thoughts on this issue?

This way when the boat is heeled over water can not come up the drain line.

I don't see any need to change it as It works well for draining small amounts of water. However, when you need to empty the cockpit in a hurry, say when its been filled after being pooped by a breaking wave, you need more drain cross-section. I added a 2" (or maybe its 1.5") drain from the cockpit aft bulkhead (as close to the cockpit floor as possible) angled down slightly to the transom. I can tell you that the last time I was up to my knees in water, I was pleased to have the extra drainage! Best, David On Tue, Aug 1, 2017 at 6:37 PM, Barbara L.
