Both the Avalon 22 ft. CC - Bow Fish 2011 and the Avalon Catalina - 22 Foot 2008 are pontoon designs, both built in aluminium, 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 - Avalon 22 ft. CC - Bow Fish 2011 at 22,0 ft versus Avalon Catalina - 22 Foot 2008 at 22,0 ft. At 2 000 lbs and 2 035 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 - 100 hp for the Avalon 22 ft. CC - Bow Fish 2011 and 100 hp for the Avalon Catalina - 22 Foot 2008. 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.
For family outings this is probably the sharpest distinction between the two. The Avalon Catalina - 22 Foot 2008 is rated for 12 passengers, while the Avalon 22 ft. CC - Bow Fish 2011 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Avalon Catalina - 22 Foot 2008 could be the deciding factor.
Bottom line: Choose the Avalon Catalina - 22 Foot 2008 if your priority is putting more people on the water - it handles 12 passengers and at 22,0 ft it has the deck room to back that rating up comfortably. The Avalon 22 ft. CC - Bow Fish 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
