Good afternoon all. We are in the process of moving the multifuel stove from the middle of the boat, to the forward port side of the front lounge. I'm having trouble locating a new cast iron chimney cowel. Because our roof has a much larger curve than normal. At a guess,I'd say right acroos the roof the curve is nearly 4"high. The best one that Midland swindlers had, just won't do. As it will make the chimney lean outboard to much. So.Can anyone advise where we might be able to either get a bespoke one made. Or hopefull, we may be able to buy one "Off the shelf" that will fit. Thanks in advance as usual. Dave and Diane. NB Tickertyboo. Weltonfield Marina.
