When two boats share the same hull type — in this case both the Avalon 29 ft. Excalibur 2012 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?
Size is the most obvious dividing line here. The Avalon 29 ft. Excalibur 2012 measures 29,0 feet overall (2012), giving it roughly 4,0 additional feet of deck space compared to the Avalon Excalibur - 25 Foot 2008 at 25,0 feet (2008). Weight tells a clearer story for trailering families: the Avalon Excalibur - 25 Foot 2008 tips the scales at 2 174 lbs — 1 889 lbs less than the Avalon 29 ft. Excalibur 2012 at 285 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 200 hp, the Avalon 29 ft. Excalibur 2012 has a 65-hp advantage over the Avalon Excalibur - 25 Foot 2008's 135-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 16 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The Avalon 29 ft. Excalibur 2012 at 29,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Avalon Excalibur - 25 Foot 2008 at 25,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
