I haven't done this yet, I've been away from the boat for a few months. But I am going to try this soon.
You have less pipe than I do and the more pipe the better according to Dickinson. I now keep the fan under the burner going on the low setting full time when the wind is high and this improves it a lot.
The H cap is not designed properly in my opinion. I had this on a previous heater and had problems with rain getting into the burner bowl. The rain comes in the upright H usually at an angle, hits the horizontal centre of the H and runs along this and down the pipe and into the burner bowl. The bottom of the horizontal square tube should be angled down toward the H uprights so the rain can't drip in. The way it is designed with 2 straight rectangles it is a real problem out here on the wet coast and I don't see too many of them being used. I also had back draft problems with this design but it was a different stove with a much smaller diameter pipe.
I would think that adding the extra 22" of pipe you have would solve it but it would stick up pretty high. I do know that a lot of the fish boats around here with long pipes seem to have no problem and they go out in all kinds of weather.
