Cockpit drain question
Ive been posting a lot of questions lately. This boat i am working on, the cockpit drains route to thru hulls below the cockpit rather than to the transom. It's a Westerly Cirrus. It does have a nice, deep cockpit, but the sole of the cockpit is still at least 4 or 5 inches above waterline. What might be the design reason to route the drains this way?
I was thinking gravity, needing to give enough vertical space to allow the water to drain.
Reason I'm asking is twofold. I don't like having to leave two seacocks open to let the cockpit drain rainwater, and they really aren't big enough so I thought about enlarging them but don't want to drill a hole in the hull, was thinking about adding a third drain instead, leading to the transom.
But I'm no marine architect, or pretend to be so anyone who knows a lot about this type of thing I would love to hear from
