When two boats share the same hull type — in this case both the Avalon 20 ft. Windjammer 2013 and the Avalon Catalina 16 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?
Size is the most obvious dividing line here. The Avalon Catalina 16 ft. 2010 measures 16,0 feet overall (2010), giving it roughly 14,0 additional feet of deck space compared to the Avalon 20 ft. Windjammer 2013 at 2,0 feet (2013). Weight tells a clearer story for trailering families: the Avalon Catalina 16 ft. 2010 tips the scales at 135 lbs — 117 lbs less than the Avalon 20 ft. Windjammer 2013 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 20 ft. Windjammer 2013 has a 65-hp advantage over the Avalon Catalina 16 ft. 2010's 50-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 20 ft. Windjammer 2013 is rated for 10 passengers, while the Avalon Catalina 16 ft. 2010 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Avalon 20 ft. Windjammer 2013 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Avalon 20 ft. Windjammer 2013 comes in at 0 lbs per hp versus 3 lbs per hp for the Avalon Catalina 16 ft. 2010. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Both are 2-tube and 2-tube pontoon designs respectively. Tube diameter and gauge affect stability and load capacity — more so than most buyers realize when comparing on paper.
Bottom line: Choose the Avalon 20 ft. Windjammer 2013 if your priority is putting more people on the water — it handles 10 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Avalon Catalina 16 ft. 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
