We installed ours fore and aft, but only because that's how the traditional marine head was installed before we replaced it. Installed athwartship, one one tack, the liquids will drain into the solids container when the back is lower than the front. Of course, this is only a big deal if you're on the same tack for days, but if you plan on doing long passages, it's something to consider. At an angle (as in, if it's installed fore and aft and you're heeled) a *bit* of liquids get into the solids container, but not really enough to affect the efficiency of the unit.

Just something to keep in mind, if you have options about how to install it.

Pictures please and who made it?

So next month we are gonna rip out the disgusting porta-potty on our boat, and install a new composting head (Nature's Head) in our Catalina 30.

I am thinking about how to install it, and was wondering if there are advantages/disadvantages to installing it facing forward, rather than facing to starboard. Would it be more or less convenient to use while underway if its facing forward vs side to side?

If we mounted it facing forward, it would be close to, but not on, centerline.

Any opinions, or better yet, experiences would be greatly appreciated.
thanks!

Re: Orientation for Composting Head?

It seems to me that with the complaints of the Nature's Head not completely separating the liquid from the solid because the lip is not high enough, then it seems the for/aft or aft/for orientation should have less effect as the motion would mostly be side to side, not shifting the liquid to the solids collection as much. Have you thought to ask the manufacturer, it may not be worth rearranging the head over it as I can't think of many heads that would allow for much modification without major work as it is normally pretty tight.

Thank you Brent, but I have used a NORMAL head underway more than I care to admit and I know exactly how it feels. I am however, referring to a COMPOSTING HEAD where liquids are supposed to go one way and solids another. Things change at an angle of heel that could influence its operation, therefore, pee could end up in the bucket, a thing you try to avoid. I am just trying to understand if a COMPOSTING HEAD facing athwartships would cause any issues. I think the question in the OP refers to this issue, not about ergonomics.

I guess this was the point I was trying to make earlier. Whichever setup on a particular boat allows you to best brace yourself, is probably the answer.

Assume, however, that the head is in the middle of the salon. That's not really a stretch on some small boats, where it is under a v-berth cushion, with nothing around you to brace. I think athwartships is probably the best option with zero bracing.

I just hate using the head when heavily heeled, period. It's the most likely thing to get me nauseous. I love being down below underway, especially seeing green water go past the port lights. However, enter the head and I'm on a timer........ weird.

Thanks all! I've never been so excited to install a toilet before

Yes, But; you still have to clean the area, so if it's disgusting it would be (Operator error!).......Dale
