Both the Twin Vee Catamarans 20 ft. Ocean Cat 2012 and the Twin Vee Catamarans 26 ft. Express 2011 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 350 hp, the Twin Vee Catamarans 26 ft. Express 2011 has a 170-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 26 ft. Express 2011 carries 120 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.

For family outings this is probably the sharpest distinction between the two. The Twin Vee Catamarans 20 ft. Ocean Cat 2012 is rated for 10 passengers, while the Twin Vee Catamarans 26 ft. Express 2011 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Twin Vee Catamarans 20 ft. Ocean Cat 2012 could be the deciding factor.
