Both the Aspen Power Catamarans C90 Cruiser 2010 and the Aspen Power Catamarans L90 Launch 2010 are catamaran designs, both built in composite, 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?
On paper these two are close siblings in the size department - Aspen Power Catamarans C90 Cruiser 2010 at 28,2 ft versus Aspen Power Catamarans L90 Launch 2010 at 28,2 ft. Weight tells a clearer story for trailering families: the Aspen Power Catamarans C90 Cruiser 2010 tips the scales at 7 900 lbs - 2 500 lbs more than the Aspen Power Catamarans L90 Launch 2010 at 5 400 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
The power gap is worth calling out. Rated to 150 hp, the Aspen Power Catamarans C90 Cruiser 2010 has a 40-hp advantage over the Aspen Power Catamarans L90 Launch 2010's 110-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 C90 Cruiser 2010 carries 80 gallons versus 60 gallons in the Aspen Power Catamarans L90 Launch 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 8 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: Performance buyers should lean toward the Aspen Power Catamarans C90 Cruiser 2010 and its 150-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Aspen Power Catamarans L90 Launch 2010 with its 110-hp rating is the more economical daily driver.
