Part of an illustration set from ABYC H-24, badly modified by me, showing how quite a few C-Dorys had their vents routed (presumably because someone thought higher was better). What happens instead is that this makes a big "fun slide" down into the tank for water. (I corrected this, while still using the original hole location, with Attwood self venting fuel vent fittings - see details in "Sunbeam ~ 22 Cruiser" thread.)
