Both the Avalon 20 ft. GS Quad Lounge 2013 and the Avalon Bow Fish 22 ft. 2010 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 20 ft. GS Quad Lounge 2013 at 20,0 ft versus Avalon Bow Fish 22 ft. 2010 at 22,0 ft. Weight tells a clearer story for trailering families: the Avalon Bow Fish 22 ft. 2010 tips the scales at 2 000 lbs - 250 lbs less than the Avalon 20 ft. GS Quad Lounge 2013 at 1 750 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 100 hp, the Avalon Bow Fish 22 ft. 2010 has a 25-hp advantage over the Avalon 20 ft. GS Quad Lounge 2013'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 Bow Fish 22 ft. 2010 is rated for 10 passengers, while the Avalon 20 ft. GS Quad Lounge 2013 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Avalon Bow Fish 22 ft. 2010 could be the deciding factor.
One place where both boats are genuinely identical is tube construction: both run 2 aluminum tubes at 23" 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.
Bottom line: Choose the Avalon Bow Fish 22 ft. 2010 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 20 ft. GS Quad Lounge 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
