Quick answer: For use on a boat, choose a purpose-built marine grill rather than a generic camping grill. Marine models are designed around corrosion resistance, secure mounting and wind management.

Best overall marine grill: Magma Newport II Infrared Gas Grill
Best compact marine grill: Magma Marine Kettle 3 Combo Stove & Gas Grill
The Newport II is purpose-built for marine use with mirror-polished stainless steel, an infrared cooking system and multiple mounting options. Magma lists a 162-square-inch cooking area, an 11,200-BTU burner and a weight of about 21 pounds.
Best for: boat owners who want a dedicated mounted grill with enough room to cook for several people.
Important: follow the mount instructions for your boat. Some mount styles are intended for use only while anchored or moored.
The Marine Kettle 3 uses a compact round format and can also function as a stove. Magma lists 133 square inches of cooking area, a 10,700-BTU burner and a weight of roughly 10 pounds.
Best for: smaller boats where storage space is limited and one compact cooking appliance needs to do more than one job.
Prioritize corrosion-resistant construction, a secure boat-specific mount, controlled grease handling, dependable wind performance and a fuel setup approved for your installation. Never improvise a mount or use a hot grill near fuel vents, canvas or enclosed spaces.
