Is there anywhere on Tortola we can rent or buy a railing mounted gas BBQ?

Why are all the BBQs on BVI charter boats charcoal? Charcoal is a pain the ..
Our preferred way to cook on the boat is on the BBQ, verses being stuck down in the galley.
With gas, it is ready to cook in a few minutes.
Seems a whole lot safer too, I've seen some crazy fires coming out of BBQs, trying heat up those charcoals.
