On this last trip Joe (lazyriverguy) had the ideal thing for you to use.
It is a tripod with a circular grill , suspended in the center. The grill can be lowered or raised for whatever you want to use it for. By using the chain that holds (suspends) the grill.
He would get a small fire going and put his coffee pot on there over the flame and then adjust it as needed , when that was done then cook a steak or anything on the grill.
The tripod broke down into three sections for storage in the boat. If you take a good look at the far right side in this picture you can see it sitting there since it was not in use.
If memory serves me correctly he got it at Tractor Supply for a few bucks , I think about $20.00 and it has a multitude of cooking uses.
Going counter clock wise from Mac with the hat and jeans , Joe Fennell , Van , Joe (lazyriverguy) and Harry. For anyone with snow on there roof , sorry guy's... it was shorts for us with upper 60's in the morning , Winter in Florida.
