Well, yes, but the vents such as the nicro or sensi are designed to be seated and water tight in the deck and can be easily adapted to accommodate the vent hose.

A computer fan is not and must be set up to draw on the house bank.

Big difference in efficiency of design, and I would not want the head's dependability and functionality reliant on the battery system. In the event I have run down my house bank, or am working on it, I want the vent on the head still buzzing away.

I have to agree with GMac. I am beginning the construction of a cruising sailboat, and these issues are paramount. What to do with crap.... My last large boat was a gaff rigged schooner, and in those days bucket and chuck it was my system. Can't do that any more. [And shouldn't]. this thread has had more precise information and detail than any website I have ever seen, without the hype that websites have. Thank you, thank you, one and all. I like the detractors because you raise issues I might not think of, and the resultant discussion is just excellent. Thank you.

O please when you get it would you let me know? Pics would be great but even just a description would be appreciated!
SARA!!!!! I thought you already had yours.
I will take some detailed pics of the kit when it arrives. I am hoping that I can use it to improve the very basic system that I have been using (bucket and bottle). I don't think I could have constructed a separating system that my wife would be willing to try for 127 dollars. Thanks again for the tip.

Computer fan draws 60 milliamps , not a big worrry about drawing down my 100 amp battery. That would take forever, if the solar panel screwed up. They cost about $2.

Yeah, the price looked totally right to me. Himself is a bit of a doubter and thought it couldn't be possible to have a bucket of crap and coir on board without it smelling and drawing flies, so we are doing a low tech test of the solid waste half of the equation. As soon as we have gotten thru a few months of steady use (and it works like I expect) we will be ordering the privy kit.

I can get really nice buckets and bottles free at a local ice creamery, and I plan on building it in, cabinet style, with a hinged top that would allow access for swapping out buckets and bottles. I figure there will be room to store the TP and blocks of coir in there as well.

Hey, Sarafina. Are there any more like you down there in California?

We have a solar vent on our Nature's Head and had a problem when stuck on a mooring in 20+ kts. for 3 days. The wind was overpowering the vent fan and blowing back into the head. I managed to fix it by taping over the vents on the fan facing the wind, but that's not a permanent solution. I'm going to add a computer fan to the system this winter to give it a little more oomph.

Ours is mounted on the port side, facing inward. On a starboard tack it is hard (impossible) to get all the liquid to flow into the pee bucket. We haven't found a solution to this yet, other than hold it or tack. Nature's Head recommends mounting fore/aft and I wish we had the room to do that.
Everything that makes it to a receptacle stay put however.

I am glad I installed an Air Head, eliminating the holding tank allowed me to switch to all chain rode.(my boat is only 30'). I installed vent to an existing nicro vent, and intend to also install supplied fan for rainy days.This will be on a switch and only used when needed. I add extra peat prior to emptying,this dilutes any waste that has not decomposed.. I normally add approx. a cup of peat a day, as it gets time to empty I increase peat.(prefer to empty every 5-6 weeks)

I made up a weather cocking top for my vent pipe out of a 2 inc ABS elbow and a 2 inch ABS coupling with a short lenght of 2 inch ABS pipe. I put it on a pivot with a counterbalance, and put a tail fin on it, so the opening will always point downwind. Draws well without the fan in strong winds , but I leave the fan on in case it falls calm.
