Avalon LS 21 ft. 2010 vs Avalon Somerset - 20 Foot 2006 — Same Brand, Different Boat

The Avalon LS 21 ft. 2010 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 LS 21 ft. 2010 measures 21,0 feet overall (2010), giving it roughly 19,0 additional feet of deck space compared to the Avalon Somerset - 20 Foot 2006 at 2,0 feet (2006). At 18 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.

Both boats share a closely matched power ceiling — 115 hp for the Avalon LS 21 ft. 2010 and 100 hp for the Avalon Somerset - 20 Foot 2006. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.

For family outings this is probably the sharpest distinction between the two. The Avalon Somerset - 20 Foot 2006 is rated for 12 passengers, while the Avalon LS 21 ft. 2010 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Avalon Somerset - 20 Foot 2006 could be the deciding factor.

Bottom line: Choose the Avalon Somerset - 20 Foot 2006 if your priority is putting more people on the water — it handles 12 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Avalon LS 21 ft. 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
