Both the Aspen Power Catamarans 48 - C150 2012 and the Aspen Power Catamarans 48 - C150 2013 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 48 - C150 2012 at 48,8 ft versus Aspen Power Catamarans 48 - C150 2013 at 48,8 ft. At 29 800 lbs and 29 800 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.
Both boats share a closely matched power ceiling - 480 hp for the Aspen Power Catamarans 48 - C150 2012 and 480 hp for the Aspen Power Catamarans 48 - C150 2013. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads - 450 gal and 450 gal - so range won't be a tiebreaker here.
Both boats are rated for 14 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 Aspen Power Catamarans 48 - C150 2012 and Aspen Power Catamarans 48 - C150 2013 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
