I like the idea of a cc boat but rather one without a walkthrough. In the length of boat I'm considering this would mean unduly raising the cockpit height, reducing both storage and privacy. Obviously I'm looking at older designs such as a Salar 40 or a Moody Halberdier 36 or a Rasmus/Nab 35. All of these have fixed doghouses for weather protection.
I have achieved this unhappy state twice in a Victor 40 and a Mirage 30 not nice but both survived and I would sail another without hesitation.
the walk through transom of my current boat has a seat that slides up and down, when up there is a 18" x 12" hole for water to escape, it does in seconds tested it once (and it wasn't weather that caused the problem it was a Dunkirk Dover ferry passing to fast to close).
My cockpit well holds about 0.75 tons of water. There are two 2 1/2 inch drains that would drain it reasonably quickly.
One way of looking at the weight would be thinking of 10 or 12 crew all sitting or lying down in the cockpit, not a great problem for 47 foot boat. Unlike AC boat the weight is near the pitch centre so there is no risk of sinking the stern down.
I think there would be other things of much more concern like how I would stand up to a ton of water landing on top of me.
Though I like centre cockpit yachts, Moodys and Westerlys particularly, disadvantages show up when mooring up with family or guests having to jump down the extra height when mooring up, and returning aboard when leaving.
Older crew are more likely to pull joints and muscles at this stage than during any other part of the cruise, and a slippery pontoon adds to the risk.
As regards the boom this is a possibility particularly on the M376 where a friend of mione gained a new painful hair parting during the RTIR with much red stuff flowing about.
All in all the extra in accommodation and general living space below are the things which will persuade the other half that a Centre cockpit arrangement is a 'good thing', hence she will come sailing regularly.
Regretfully I have a small aft cockpit Westerly so seldom have other half aboard-(vertigo).
