* Specifically, he wants to plug up the aft vent on the tank rather than go forward with two vents.
* As for the forward vent through-hull, he's concerned about siphoning, so he wants to run the vent hose in a loop above the through-hull before connecting rather than doing a straight run from the tank opening to the through-hull.
Really bad idea... will basically stop any air flow and cause the tank to load up with anaerobic (stinky) bacteria.
* In addition, he's inclined to locate the single vent through-hull on the side of the main cabin to reduce the risk of siphoning.
* As for me, I've been inclined all along to think there should be TWO vents, to run the vent hose in a straight path to the through-hull, and to locate them just below the toerail.
Good idea, provided they're actually two separate vent lines with separate tank openings. Maximizes the airflow through the tank and helps promote the low-stench aerobic bacteria.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
