When two boats share the same hull type — in this case both the Aspen Power Catamarans 28 - C90 Cruiser 2011 and the Aspen Power Catamarans 36 - C110 2012 are catamaran designs with composite 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?

Size is the most obvious dividing line here. The Aspen Power Catamarans 36 - C110 2012 measures 36,5 feet overall (2012), giving it roughly 8,3 additional feet of deck space compared to the Aspen Power Catamarans 28 - C90 Cruiser 2011 at 28,2 feet (2011). At 79 lbs and 18 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 260 hp, the Aspen Power Catamarans 36 - C110 2012 has a 110-hp advantage over the Aspen Power Catamarans 28 - C90 Cruiser 2011's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Aspen Power Catamarans 36 - C110 2012 carries 18 gallons versus 8 gallons in the Aspen Power Catamarans 28 - C90 Cruiser 2011. 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 Aspen Power Catamarans 36 - C110 2012 is rated for 11 passengers, while the Aspen Power Catamarans 28 - C90 Cruiser 2011 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Aspen Power Catamarans 36 - C110 2012 could be the deciding factor.
