When two boats share the same hull type — in this case both the Avalon Excalibur 25 ft. 2010 and the Avalon Windjammer Sandbar 2012 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 Excalibur 25 ft. 2010 at 25,0 ft versus Avalon Windjammer Sandbar 2012 at 26,0 ft. Weight tells a clearer story for trailering families: the Avalon Windjammer Sandbar 2012 tips the scales at 3 125 lbs — 2 880 lbs less than the Avalon Excalibur 25 ft. 2010 at 245 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 300 hp, the Avalon Windjammer Sandbar 2012 has a 150-hp advantage over the Avalon Excalibur 25 ft. 2010's 150-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 Windjammer Sandbar 2012 is rated for 17 passengers, while the Avalon Excalibur 25 ft. 2010 caps at 13. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Avalon Windjammer Sandbar 2012 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.
Bottom line: Choose the Avalon Windjammer Sandbar 2012 if your priority is putting more people on the water — it handles 17 passengers and at 26,0 ft it has the deck room to back that rating up comfortably. The Avalon Excalibur 25 ft. 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 13 that costs less to run day-to-day.
