I agree, that is about the ugliest scupper installation I've seen

On higher numbered boats, the factory appears to have moulded in deck scuppers aft of the cabin trunk. The outlet is at the waterline. An earlier owner added scuppers to #76 and used flat faced bronze through hulls at the deck and rounded through hulls at the water line. Hole diameter could have been larger, but is ok.

Also, in the case of #76, the scuppers were placed ahead of the boat's low point where the water collects. I'm sure it was the low point at one time Just another reason to keep the weight down in the after most part of the boat.
