Both the Avalon 24 ft. Catalina 2011 and the Avalon 24 ft. Windjammer 2013 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 24 ft. Catalina 2011 at 24,0 ft versus Avalon 24 ft. Windjammer 2013 at 24,0 ft. At 2 200 lbs and 2 250 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.

Both boats share a closely matched power ceiling - 130 hp for the Avalon 24 ft. Catalina 2011 and 135 hp for the Avalon 24 ft. Windjammer 2013. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.

For family outings this is probably the sharpest distinction between the two. The Avalon 24 ft. Windjammer 2013 is rated for 13 passengers, while the Avalon 24 ft. Catalina 2011 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Avalon 24 ft. Windjammer 2013 could be the deciding factor.

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.
