The Avalon 25 ft. Ambassador 2011 vs Avalon Somerset - 20 Foot 2006 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Avalon 25 ft. Ambassador 2011 measures 25,0 feet overall (2011), giving it roughly 23,0 additional feet of deck space compared to the Avalon Somerset - 20 Foot 2006 at 2,0 feet (2006). At 37 lbs and 17 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.
The power gap is worth calling out. Rated to 250 hp, the Avalon 25 ft. Ambassador 2011 has a 150-hp advantage over the Avalon Somerset - 20 Foot 2006's 100-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Avalon 25 ft. Ambassador 2011 carries 42 gallons versus 36 gallons in the Avalon Somerset - 20 Foot 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Bottom line: The Avalon 25 ft. Ambassador 2011 at 25,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Avalon Somerset - 20 Foot 2006 at 2,0 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.
