Choice of equipment: Origo 1500 Spirit Stove, Pan-2000 heater, Dometic 972 portable toilet, Waeco Tropicool TC21FL cool box

Installation and use:

The spirit stove is mounted on the gimballs sold as (rather expensive) accessories and these are mounted in a wooden frame which is normally slotted into teak holders (similar to those used for the chart plotter) at the side of the sink. It can be slid out as a unit in order to cook in the cockpit. For fuel I'm using low-odour bio-ethanol (from Contemporary Elements). This is pricey at £3 per litre delivered (if you buy 20l) but I think well worth it for the lack of smell. Like all carbon fuels burning it produces water vapour and carbon monoxide gas - I've written a separate comment on gas alarms.

Toilet I chose the Dometic 972 portable toilet because of it's relatively small dimensions. It will only be used on over-night trips: I use the hand bailer from an Optimist dinghy as a urinal! What I hadn't thought about was that the water tank for flushing weighs a few kg if full - so I use a bailer-full of sea water for flushing and the toilet simply acts as an holding tank without built-in flush. I've enlarged the openings into the "V berth storage lockers" and the toilet sits in the starboard one. That gives headroom and space for using it.

N.B. : The opinions expressed are my own after a relatively short period of use; there may be ways around any problems identified. Other users will have different priorities!
