I have no actual experience with these stoves so obviously my considerations are purely theoretical. I did have a few thoughts though.

I watched the video which Neil linked to. My first thought was that although efficient for cooking, it seems this would be rather inefficient for heating. The force of the draft it seems would blow most of the heat straight out the chimney. Page 4 of the PDF about improving wood stoves shows a diagram of a similar stove but with an extended horizontal chamber to capture more of the heat before it escapes.

It does seem like the high pressure draft could be an asset on a boat in resisting wind and back draft but also a liability in that it could potentially blow flaming bits and soot on deck, dock, sail, etc.

I had an idea for a self feeding mechanism for the stove. It's a bit complicated so bear with me. Essentially you would have a seperate intake on the stove for fuel and for air. The intake for the sticks would be longer, maybe 2ft or so and capped at the end. At the base would be a separate, and adjustable air intake. This would allow you to adjust draft and rate of burn. The inclined fuel intake would allow the fuel to "self feed" as the end of the stick is consumed, more would slide down to the vented burn area. You could also have a grate area at the base of the burn area to capture and separate the ashes.
