If the thru hull and drain are on the same side, they both “drop” the same amount. If they are crossed, when the thru-hull drops lower, the connected drain goes higher

Wonder what degree of heel it would take to achieve that. One would think that it would be extreme and that one would want to reduce that as soon as possible. I think that regardless, if the cockpit floor scupper is below the water line, I don't care where the through hull is for that particular scupper, I got more things to worry about. Having them crossed it is easy for me to imagine a heel where the through hull is higher than the drain. I don't see how that helps. The normal way the through hull is below the drain unless the boat is upside down. I am not saying it's wrong, just trying to understand the geometry and drainage.

I don't think they are above the waterline. The aft cockpit floor is lower than the forward one. Both sets of drains are forward. Replaced valves and hoses a few years ago. Reused the through hulls although the tabs inside got busted trying to hold them to unscrew the valves. C&C should have used real through hulls that are bolted to the hull.

My buddy is a salvor. He gets the call when a boat on our bayou is on the bottom. A significant percentage of the sinkings involve plugged cockpit scupper drains. Leaves and/or debris plug the drain(s). The cockpit fills with rain water. The weight of the water sinks the boat until the cockpit scuppers are submerged and down it goes. Sometimes a neglected boat with a low companionway threshold will get so much rain water in the cockpit it overflows into the cabin. Leave the cockpit seacocks open and make sure they are clear. I flush Touche's twice a year. Who knows what spider, mud dauber of whatever builds a nest in them. Also, on haul out. Make sure you know which way your cockpit drains. Block the boat accordingly. The 35-1 cockpit, like others, drains forward. I always make sure Touche' is blocked level or slightly bow down. Also, just as a note, the 35-1 has 4 cockpit scupper drains. Two of them are in the aft steering station which is separated from the rest of the cockpit by a bulkhead. These two drain exit at or slightly above the waterline when the boat is floating on its lines. Dennis C. Touche' 35-1 #83 Mandeville, LA
