When two boats share the same hull type — in this case both the Avalon 20 ft. Windjammer 2011 and the Avalon Windjammer Rear Loungers 2011 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 Windjammer Rear Loungers 2011 measures 24,0 feet overall (2011), giving it roughly 22,0 additional feet of deck space compared to the Avalon 20 ft. Windjammer 2011 at 2,0 feet (2011). At 18 lbs and 3 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 250 hp, the Avalon Windjammer Rear Loungers 2011 has a 135-hp advantage over the Avalon 20 ft. Windjammer 2011's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Avalon Windjammer Rear Loungers 2011 carries 42 gallons versus 24 gallons in the Avalon 20 ft. Windjammer 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Avalon Windjammer Rear Loungers 2011 is rated for 15 passengers, while the Avalon 20 ft. Windjammer 2011 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Avalon Windjammer Rear Loungers 2011 could be the deciding factor.

Both are 2-tube and 3-tube pontoon designs respectively. Tube diameter and gauge affect stability and load capacity — more so than most buyers realize when comparing on paper.
