Mono hull to Cat

I am going to Key West at the end of this month and want to rent a sailboat for a day: 35-40 ft. I have looked at few places renting monohulls but there seems to be many more catamarans for rent. Probably better for the shallower waters around the keys.

I am a competent/experienced monohull sailor, but the only catamarans I have sailed are hobie cats. Would my monohull skills allow me to handle a catamaran? Or would that be reckless on my part.
