Both the Twin Vee Catamarans 20 ft. Ocean Cat 2012 and the Twin Vee Catamarans 36 ft. Pilot House 2013 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 700 hp, the Twin Vee Catamarans 36 ft. Pilot House 2013 has a 520-hp advantage over the Twin Vee Catamarans 20 ft. Ocean Cat 2012's 180-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Twin Vee Catamarans 36 ft. Pilot House 2013 carries 480 gallons versus 72 gallons in the Twin Vee Catamarans 20 ft. Ocean Cat 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 10 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The Twin Vee Catamarans 36 ft. Pilot House 2013 at 35,8 ft is the right call if deck space, comfort, and entertaining are top of your list. The Twin Vee Catamarans 20 ft. Ocean Cat 2012 at 20,0 ft wins on trailering ease, likely lower purchase price, and simpler docking - a solid choice for a buyer who wants more boat for less money.
