I was crawling around in "the hole" yesterday to re-route some bilge hose and also check the job the diesel repair did on tightening/repacking my stuffing box. Since I am hearing a lot of sinking boats lately, I thought I would inspect all the thru-hulls in the stern area. I didn't get a picture but I am wondering why two of the cockpit drain hosts go to a big seacock on the bottom center of the boat (under the cockpit) ? Is that a normal setup ? The boat was setup for racing and I know there are offshore regulations regarding how fast the cockpit drains, so I am wondering if these were added or do all boats have 4 drain hoses ?
