When two boats share the same hull type — in this case both the Avalon 25 ft. Deco Sandbar 2013 and the Avalon 27 ft. Excalibur 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?
On paper these two are close siblings in the size department — Avalon 25 ft. Deco Sandbar 2013 at 25,0 ft versus Avalon 27 ft. Excalibur 2011 at 27,0 ft. Weight tells a clearer story for trailering families: the Avalon 27 ft. Excalibur 2011 tips the scales at 265 lbs — 234 lbs less than the Avalon 25 ft. Deco Sandbar 2013 at 31 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 250 hp, the Avalon 25 ft. Deco Sandbar 2013 has a 75-hp advantage over the Avalon 27 ft. Excalibur 2011's 175-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 14 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.
Both are 3-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.
Bottom line: Performance buyers should lean toward the Avalon 25 ft. Deco Sandbar 2013 and its 250-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Avalon 27 ft. Excalibur 2011 with its 175-hp rating is the more economical daily driver.
