Thanks Annie. 

Hard to visualize the final result though, being close up in the tent. Got a peek at her looks when turning the hull, which was nice. 

Shallow draft with standing headroom in the cabin area. Lots of freeboard there. Form follows function.

I’m counting on some smart color scheme to get it right. You nailed it with Fanshi.

A little update on the HF34. First layer of 10 mm okume ply in place. Extra ply in lieu of daggerboard case and on both sides of the companionway where the winches will be. 

Next layer will be 14 mm foam core, glued on top of the ply deck. 

Mast offset approx. 5” to starboard, forward of the daggerboard case.

Mocking up some of the placement of mast partners, witches and anchor stuff. Just because I can....

Frederik, I also made my own, used a separator from Strumpet & Trollop in the UK. Not cheap but very well made in GRP. See:

I'm also totally satisfied.... Yes, do not skip the computer fan, I'm using an 80mm one as it quieter than the smaller ones. Not because of me (I hear nothing) but so that Grasshopper's sensitive ears will not be traumatized when she visits :-).

Can anyone recommend a composting alternative?

I built a waterless toilet, (sometimes called composting), for my recent catamaran build. After 18 months of use the toilet has proven to be very successful, maybe the best boat toilet I have ever had, and Annie Hill has a similar toilet in Fanshi which she also built. My toilet is based on the Tribolo toilet designs which are in Europe, but I built my own for less than NZ$100. I used a urine separator which came from Free Range Designs in the UK. I also have an extractor fan based on a small permanent magnet computer fan which removes all unpleasant odours.

Yes, I can. You may buy a $2 or $3K machine, but I went other way. My expenditure was about €100 seperator+ styrofoam seat and cover. They are OK, as long as you do not accidantly sit on the cover, as I did. After 25 days of instant utilisation I may reccomend it. It works, does not smell (as others say). The urine hose I replaced with a 4 liter bottle. In the front part of the separator I put small disinfectant blocks, such as in the toilets - works perfectly and cost almost nothing. I do not have an exhaust fan, maybe I will install it one day. I sprinkle the poop with a mixture of wood chips and peat, I also throw in the used paper. Sometimes you have to mix it up with a stick.
