When two boats share the same hull type — in this case both the Avalon 19 ft. LS 2011 and the Avalon LS - Bow Fish 21 ft. 2010 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 19 ft. LS 2011 at 19,0 ft versus Avalon LS - Bow Fish 21 ft. 2010 at 21,0 ft. Weight tells a clearer story for trailering families: the Avalon 19 ft. LS 2011 tips the scales at 165 lbs — 147 lbs more than the Avalon LS - Bow Fish 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.

The power gap is worth calling out. Rated to 115 hp, the Avalon LS - Bow Fish 21 ft. 2010 has a 25-hp advantage over the Avalon 19 ft. LS 2011's 90-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 - Bow Fish 21 ft. 2010 is rated for 10 passengers, while the Avalon 19 ft. LS 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 LS - Bow Fish 21 ft. 2010 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.
