I can tell you why I chose to install one:
I had a small cruising trimaran
with little room for a holding tank and I also didn't want the weight of a large holding tank. The composting head
fit on about the same foot print and a small 3-gallon holding tank for the urine fit under the floorboards and was a simple gravity feed system.
Another reason to "go through the trouble" is that this system requires no below the water
line through hull
fittings. There is also no worry of getting a citation from the coast guard because you forgot to lock a valve closed.
In actuality, found the lack of plumbing
made installing and maintaining it simpler than a traditional marine head
. (No seacocks, no anti-siphon valves to clog, to pump to clog, no head
Although it was simple in many ways, it is not what I'd choose for a long term cruising
on a larger, heavier displacement
boat where the space and weight of a holding tank is not an issue. I'd choose a composting head again if I purchased another trailerable pocket cruiser
for short trips, especially for great lakes
cruising, where one can never dump overboard
