When two boats share the same hull type — in this case both the Twin Vee Catamarans 19 ft. Dual Console Bay Cat 2012 and the Twin Vee Catamarans 36 ft. Weekender 2011 are catamaran designs with fiberglass construction — 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 600 hp, the Twin Vee Catamarans 36 ft. Weekender 2011 has a 460-hp advantage over the Twin Vee Catamarans 19 ft. Dual Console Bay Cat 2012's 140-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. Weekender 2011 carries 34 gallons versus 4 gallons in the Twin Vee Catamarans 19 ft. Dual Console Bay 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 36 ft. Weekender 2011 is rated for 10 passengers, while the Twin Vee Catamarans 19 ft. Dual Console Bay Cat 2012 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Twin Vee Catamarans 36 ft. Weekender 2011 could be the deciding factor.
