Cockpit Drain Plumbing ?

Greetings,

Is it acceptable to have cockpit drains plumbed to drain through a thru hull that is below the waterline on the centerline of the boat? The thru hull does have a valve that can be closed if needed in an emergency. A previous survey stated the cockpit drain plumbing "satisfactory" but I wanted to hear what the group thought?

Thanks for your time.

Michael

I dont think it is really important where your drains exit although I like them above the water line. I just read somewhere that it recommended that your cockpit should drain in 90 seconds or less. My old Irwin 10/4 had two drains that where 1 1/2 inch and the previous owner also install two six inch drains that drained aft above the waterline and had flapper valves to keep a following sea out worked great.

Center cockpit pretty much has to have below water thru hull drains. We have 2 that go straight down to the bottom of the boat with new valves
