Self bailing

I used to have a C&C 24 which had the most absurd cockpit drain settup, they sloped the sole forward to a point about a foot from the companionway where it leveled off, then they installed a 1.25" drain each side at the transition which merged below the sole to a single 1.5" seacock through the bottom close to centerline. The most absurd thing is that the sole is about a foot above the waterline and runs almost to the transom, there is a back wall to the cockpit in the deck molding which is about 4" and paralell to the transom, it would have been a simple matter for the designers to slope the sole toward the transom and away from the companionway and instal 2 huge slots with flaps.
Btw, i have always found the term self bailing strange, bailing is something you do with a bucket, self draining makes more sense to me.
