When two boats share the same hull type — in this case both the Avalon 18 ft. Windjammer 2012 and the Avalon Paradise - 22 Foot 2008 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 Paradise - 22 Foot 2008 measures 22,0 feet overall (2008), giving it roughly 4,0 additional feet of deck space compared to the Avalon 18 ft. Windjammer 2012 at 18,0 feet (2012). Weight tells a clearer story for trailering families: the Avalon Paradise - 22 Foot 2008 tips the scales at 2 035 lbs — 1 870 lbs less than the Avalon 18 ft. Windjammer 2012 at 165 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 Paradise - 22 Foot 2008 has a 35-hp advantage over the Avalon 18 ft. Windjammer 2012'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 Paradise - 22 Foot 2008 is rated for 14 passengers, while the Avalon 18 ft. Windjammer 2012 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Avalon Paradise - 22 Foot 2008 could be the deciding factor.
Bottom line: Choose the Avalon Paradise - 22 Foot 2008 if your priority is putting more people on the water — it handles 14 passengers and at 22,0 ft it has the deck room to back that rating up comfortably. The Avalon 18 ft. Windjammer 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
