When two boats share the same hull type — in this case both the Avalon CT Fish - 18 Foot 2008 and the Avalon LS 22 ft. 2009 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 LS 22 ft. 2009 measures 22,0 feet overall (2009), giving it roughly 4,0 additional feet of deck space compared to the Avalon CT Fish - 18 Foot 2008 at 18,0 feet (2008). Weight tells a clearer story for trailering families: the Avalon CT Fish - 18 Foot 2008 tips the scales at 1 491 lbs — 1 286 lbs more than the Avalon LS 22 ft. 2009 at 205 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 125 hp, the Avalon LS 22 ft. 2009 has a 50-hp advantage over the Avalon CT Fish - 18 Foot 2008's 75-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Avalon LS 22 ft. 2009 is rated for 11 passengers, while the Avalon CT Fish - 18 Foot 2008 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Avalon LS 22 ft. 2009 could be the deciding factor.
Bottom line: Choose the Avalon LS 22 ft. 2009 if your priority is putting more people on the water — it handles 11 passengers and at 22,0 ft it has the deck room to back that rating up comfortably. The Avalon CT Fish - 18 Foot 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
