Your right, there is an odor on the outside and if you get your nose right up to the vent, you will detect a not unpleasant earthy type smell.
For my money it beats the holding tank system, odor included.
FYI - most 'head' experts say not to use a filter on the vent line, it restricts the flow of needed oxygen to the bacteria in the tank. Most recommend multiple and larger vents as well.

It’s the smell he’s concerned about… and the vent. The Air-head has both.

Get a Airhead composting Head and loose all the plumbing, tanks, switches, pumps, thru hulls along with the hassle and stink!

I have a Sealand tank vent filter like this one:
http://www.sealandsanitation.com/holding_tank_acc.htm
At that price I'm getting a little tired of replacing them.
Are there any worthwhile alternatives?
Unfortunately, due to a little inattention, my waste-tank gets over-full
once in a while. So that poor air filter becomes contaminated. Then it
blocks with sediment. When it blocks, the tank tends to to inflate (no
venting). An inflated waste tank is not a fun toy.
There is a rise of about 4 feet to that vent filter, and I have no
opportunity to position it higher. Also, the vent outflow is near the
cockpit, so the odor filtering is much appreciated...
I suppose I could snake the vent another 25/30 feet, many ups and downs
to the transom. But the likelihood of plugging would be high in that
configuration (dips in the hose would cause sediment accumulation).
Any good ideas out there? Your advice is appreciated..
-Neal.
