Avalon Somerset - 20 Foot 2008 vs Avalon Tropic - 20 Foot 2006 — Same Brand, Different Boat

The Avalon Somerset - 20 Foot 2008 vs Avalon Tropic - 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.

On paper these two are close siblings in the size department — Avalon Somerset - 20 Foot 2008 at 2,0 ft versus Avalon Tropic - 20 Foot 2006 at 2,0 ft. At 187 lbs and 158 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 — 100 hp for the Avalon Somerset - 20 Foot 2008 and 90 hp for the Avalon Tropic - 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. Fuel capacity breaks the other way: the Avalon Somerset - 20 Foot 2008 carries 36 gallons versus 24 gallons in the Avalon Tropic - 20 Foot 2006. 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 2008 is rated for 12 passengers, while the Avalon Tropic - 20 Foot 2006 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Avalon Somerset - 20 Foot 2008 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Avalon Tropic - 20 Foot 2006 comes in at 2 lbs per hp versus 2 lbs per hp for the Avalon Somerset - 20 Foot 2008. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

Bottom line: Choose the Avalon Somerset - 20 Foot 2008 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 Tropic - 20 Foot 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
