When two boats share the same hull type — in this case both the Avalon 26 ft. Windjammer 2013 and the Avalon Excalibur - 25 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?
On paper these two are close siblings in the size department — Avalon 26 ft. Windjammer 2013 at 26,0 ft versus Avalon Excalibur - 25 Foot 2008 at 25,0 ft. Weight tells a clearer story for trailering families: the Avalon 26 ft. Windjammer 2013 tips the scales at 2 475 lbs — 301 lbs more than the Avalon Excalibur - 25 Foot 2008 at 2 174 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.
Both boats share a closely matched power ceiling — 150 hp for the Avalon 26 ft. Windjammer 2013 and 135 hp for the Avalon Excalibur - 25 Foot 2008. 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 Excalibur - 25 Foot 2008 is rated for 16 passengers, while the Avalon 26 ft. Windjammer 2013 caps at 14. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Avalon Excalibur - 25 Foot 2008 could be the deciding factor.
Bottom line: Choose the Avalon Excalibur - 25 Foot 2008 if your priority is putting more people on the water — it handles 16 passengers and at 25,0 ft it has the deck room to back that rating up comfortably. The Avalon 26 ft. Windjammer 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 14 that costs less to run day-to-day.
