Yes. Brilliant bit of kit for something so simple. Small tank means short duration and messy filling but fine for occasional use in a small boat. Obviously only available second hand.
This year we just used a few feuerhand lamps (with suitable ventilation) to help keep the chill off in the cabin on our Hustler 30. It did that OK I suppose but it never got 'cosy'. I'm wondering if a Victory would push out a little more warmth and if I could rig it in the galley area with the 'flue' out through the hatch on the odd evening when needed rather than permanently install it on a bulkhead with a through-deck chimney ('cos I have the offshore version H30 and I don't really have a suitable space on a bulkhead anyway).
I toyed with the tilley idea but presume the Victory (with flue) would help kick some of the fumes and moisture it produces outside.
I have one, it is basically a primus stove in a box. I mainly use it in the winter, when the boat is ashore, and I am doing stuff.
Never got around to fitting a flue for the reasons you have mentioned KevO. Mine is fitted high on the main bulkhead and I had to fit a heat deflector in order to protect the deckhead from being singed. At one time, I had intended to always use the thing low down by the forecabin bunks, with the flexi flue through the forehatch but this has never come to pass. Probably it should.
As long as you do nothing daft, like sleeping or shutting off ventilation you could be ok but you must be aware of the dangers. I always have the main hatch opened, forehatch as well.
As it is we crack and prop open the forepeak hatch about an inch and also put the washboards in and leave the top slider open 2 inches or so. CO alarm fitted and 4 paraffin lamps burning and nothing left on when we bed down.
