Avalon Somerset - 20 Foot 2007 vs Avalon Windjammer 24 ft. 2010: Same Brand, Different Boat

The Avalon Somerset - 20 Foot 2007 vs Avalon Windjammer 24 ft. 2010 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 Windjammer 24 ft. 2010 measures 24,0 feet overall (2010), giving it roughly 4,0 additional feet of deck space compared to the Avalon Somerset - 20 Foot 2007 at 20,0 feet (2007). Weight tells a clearer story for trailering families: the Avalon Windjammer 24 ft. 2010 tips the scales at 2 200 lbs - 330 lbs less than the Avalon Somerset - 20 Foot 2007 at 1 870 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 130 hp, the Avalon Windjammer 24 ft. 2010 has a 30-hp advantage over the Avalon Somerset - 20 Foot 2007'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 Somerset - 20 Foot 2007 carries 36 gallons versus 24 gallons in the Avalon Windjammer 24 ft. 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Avalon Somerset - 20 Foot 2007 is rated for 12 passengers, while the Avalon Windjammer 24 ft. 2010 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Avalon Somerset - 20 Foot 2007 could be the deciding factor.

Bottom line: Choose the Avalon Somerset - 20 Foot 2007 if your priority is putting more people on the water - it handles 12 passengers and at 20,0 ft it has the deck room to back that rating up comfortably. The Avalon Windjammer 24 ft. 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 11 that costs less to run day-to-day.
