HMM? That is a good question! I even went to double check, if possible, sadly no. I put the drain below the sole and that makes the front lockers deeper than the sole anchor is just deep enough to hook the anchor where the shank is hanging down and just clears the bottom of the locker. Had to cut the first bottom out and make it deeper and smaller. Worked out cause stowing the anchor, line use in aft part of locker and the last thing is the anchor chain and anchor, so the chain holds the shank and keeps it from bang the side in rough seas.
But I think I have a plan that may work, and I will not have to do any cutting. But the plan keeps evolving in my head. And keep going over the physics of it. I can cut a thin section off a elbow or any 3/4" PVC fitting. shove the PVC through the final opening and through the drain opening in the bottom of the lockers I glue the fitting piece on to form a flange. Spin the pvc pipe and add silicone adhesive to the back side of the flange. Once the silicone goes all the way around the flange, connect the other end of the PVC pipe to the drainpipe at the inspection port. Let all cure for a few days. Water test again to confirm plan A worked. Plan B would be re-design forward lockers and drain to above sole. I hope plan B doesn't have to be used.
