Ocean Cat 2012 are catamaran designs, both built in fibreglass, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
The power gap is worth calling out. Rated to 500 hp, the Twin Vee Catamarans 29 ft. Ocean Cat 2012 has a 270-hp advantage over the Twin Vee Catamarans 22 ft.
