When two boats share the same hull type — in this case both the Avalon LS 21 ft. 2010 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?

On paper these two are close siblings in the size department — Avalon LS 21 ft. 2010 at 21,0 ft versus Avalon LS 22 ft. 2009 at 22,0 ft. Weight tells a clearer story for trailering families: the Avalon LS 22 ft. 2009 tips the scales at 205 lbs — 187 lbs less than the Avalon LS 21 ft. 2010 at 18 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 — 115 hp for the Avalon LS 21 ft. 2010 and 125 hp for the Avalon LS 22 ft. 2009. 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 LS 22 ft. 2009 is rated for 11 passengers, while the Avalon LS 21 ft. 2010 caps at 10. 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.

One place where both boats are genuinely identical is tube construction: both run 2 aluminum tubes at 25" diameter. That shared spec means stability and buoyancy characteristics are closely matched — the ride difference you'll feel between them comes primarily from deck length, weight distribution, and motor choice.
