Capt Dave,
Now you're cooking!
Given the price of of a Broadwater or Force Ten swinging stove - and the amount of room they take up, even the two burner with the broiler - those Sea Swing stoves look pretty good.
You bring up the fact that they are not meant to take a ten inch pressure cooker.
Do you think the fence on the cooker can be altered to take the larger pot? Will they take the weight and swing properly?
