I have one used Magma Original "Marine Kettle" Charcoal Grill
. This grill
came off a boat
I bought and I don't need it. It is used and the stainless is pretty dirty but everything works. It includes a Magma mount that attaches to a 1" tubing (like stanchion or pulpit. With a rubber strip it will fit 7/8" tubing too. The bottom grate that holds the charcoal has a couple broken pcs and may need to be replaced some time fairly soon. It's a very serviceable grill.
Model A10-004 Original Size: 14-1/2" (36.8 cm)
