He has a thread on Cruising Anarchy. Looks overpowered to me but he gets good speed and wins races. He also contends with no bridgedeck on the boat and reports that pool will dump on the cockpit sole(on a tack) and can douse the cabin if the lower hatchboard isn't in place. Shots show his rail underwater and the source of the pool looks like his bouncing stern wave crest finds it's way over the lower aft end of the coamings.

Morgan's eye would have seen that in his drawing(I bet). But what to do? In that era, seat drains were pretty common. Some glass boats of that era put a small drain in and plumbed it into the cockpit well. In the Morgans case at that much heel - in my minds eye - I don't think that would work. They could have T'ed into a cockpit drain hose, but same problem. And that was frowned upon. Interior scupper drain pipes (like my or Paul's boat) would work, but they could be costly.

In the end, maybe production $ department said, 'forgitaboutit.'

The leeward rail - amidships - can go under on my boat. Aft though, stays dry under sail. The wider decks and higher coamings keep water out of the cockpit. But my boat doesn't like to sail heeled like the Morgan.

Any water that does find it's way seeps along the corner of the seat and coaming(leaving your butt dry if you're on the lee bench) and nicely exits before the bridge deck.

I have more of an appreciation of that 1959 design with rebuilding the cockpit. All this stuff about cockpit design we're talking about here, was soooo old in 1959. Perfection is impossible but fun to chase. I'll be shining up those little bronze scuppers and put them back right where Alden put them.
