When two boats share the same hull type — in this case both the Avalon 18 ft. CT - Fish N Fun 2011 and the Avalon 22 ft. CC - Rear Fish 2011 are pontoon designs with aluminum 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 Avalon 22 ft. CC - Rear Fish 2011 measures 22,0 feet overall (2011), giving it roughly 4,0 additional feet of deck space compared to the Avalon 18 ft. CT - Fish N Fun 2011 at 18,0 feet (2011). Weight tells a clearer story for trailering families: the Avalon 18 ft. CT - Fish N Fun 2011 tips the scales at 165 lbs — 163 lbs more than the Avalon 22 ft. CC - Rear Fish 2011 at 2 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.
Both boats share a closely matched power ceiling — 90 hp for the Avalon 18 ft. CT - Fish N Fun 2011 and 100 hp for the Avalon 22 ft. CC - Rear Fish 2011. 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. Fuel capacity breaks the other way: the Avalon 18 ft. CT - Fish N Fun 2011 carries 24 gallons versus 12 gallons in the Avalon 22 ft. CC - Rear Fish 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 Avalon 22 ft. CC - Rear Fish 2011 is rated for 10 passengers, while the Avalon 18 ft. CT - Fish N Fun 2011 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Avalon 22 ft. CC - Rear Fish 2011 could be the deciding factor.
Both are 2-tube and 2-tube pontoon designs respectively. Tube diameter and gauge affect stability and load capacity — more so than most buyers realize when comparing on paper.
Bottom line: Choose the Avalon 22 ft. CC - Rear Fish 2011 if your priority is putting more people on the water — it handles 10 passengers and at 22,0 ft it has the deck room to back that rating up comfortably. The Avalon 18 ft. CT - Fish N Fun 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
