Achilles RS-116 2007 vs Achilles SGX-122 2010 — Same Brand, Different Boat

The Achilles RS-116 2007 vs Achilles SGX-122 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.

On paper these two are close siblings in the size department — Achilles RS-116 2007 at 11,0 ft versus Achilles SGX-122 2010 at 12,2 ft. Weight tells a clearer story for trailering families: the Achilles SGX-122 2010 tips the scales at 188 lbs — 113 lbs less than the Achilles RS-116 2007 at 75 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 Achilles SGX-122 2010 tops out at 35 hp. Engine specs for the Achilles RS-116 2007 aren't listed — confirm with a dealer before selecting an outboard.

For family outings this is probably the sharpest distinction between the two. The Achilles SGX-122 2010 is rated for 5 passengers, while the Achilles RS-116 2007 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Achilles SGX-122 2010 could be the deciding factor.

Bottom line: Choose the Achilles SGX-122 2010 if your priority is putting more people on the water — it handles 5 passengers and at 12,2 ft it has the deck room to back that rating up comfortably. The Achilles RS-116 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.

Achilles RS-116 2007 vs Achilles SGX-122 2010 — Common Questions

Which is the larger boat — the Achilles RS-116 2007 or the Achilles SGX-122 2010?
The Achilles SGX-122 2010 is the longer of the two at 12,2 feet overall. The Achilles RS-116 2007 comes in at 11,0 feet, making it roughly 1,2 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Achilles RS-116 2007 or the Achilles SGX-122 2010?
For trailering, the Achilles RS-116 2007 has the edge at 75 lbs dry weight versus 188 lbs for the Achilles SGX-122 2010. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
What is the maximum horsepower rating for these boats?
The Achilles SGX-122 2010 has a documented max rating of 35 hp. Engine specifications for the Achilles RS-116 2007 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.
How many people can each boat hold?
The Achilles RS-116 2007 is Coast Guard rated for 3 passengers, while the Achilles SGX-122 2010 is certified for 5. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Achilles RS-116 2007 and Achilles SGX-122 2010 share an 5 ft. 4 in beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Are the Achilles RS-116 2007 and Achilles SGX-122 2010 from the same manufacturer?
Yes — both the Achilles RS-116 2007 and the Achilles SGX-122 2010 are built by Achilles. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
