Achilles SGX-122 2013 vs Achilles SU-14 2007 — Same Brand, Different Boat

The Achilles SGX-122 2013 vs Achilles SU-14 2007 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 SGX-122 2013 at 12,2 ft versus Achilles SU-14 2007 at 14,0 ft. Weight tells a clearer story for trailering families: the Achilles SGX-122 2013 tips the scales at 167 lbs — 139 lbs more than the Achilles SU-14 2007 at 28 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.

Both boats share a closely matched power ceiling — 35 hp for the Achilles SGX-122 2013 and 55 hp for the Achilles SU-14 2007. 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.

Both boats are rated for 6 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

At this size, power-to-weight ratio matters more than outright horsepower. The Achilles SU-14 2007 comes in at 1 lbs per hp versus 5 lbs per hp for the Achilles SGX-122 2013. 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.

The Achilles SGX-122 2013 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Achilles SU-14 2007 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.

Bottom line: Performance buyers should lean toward the Achilles SU-14 2007 and its 55-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Achilles SGX-122 2013 with its 35-hp rating is the more economical daily driver.

Achilles SGX-122 2013 vs Achilles SU-14 2007 — Common Questions

Which is the larger boat — the Achilles SGX-122 2013 or the Achilles SU-14 2007?
The Achilles SU-14 2007 is the longer of the two at 14,0 feet overall. The Achilles SGX-122 2013 comes in at 12,2 feet, making it roughly 1,8 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Achilles SGX-122 2013 or the Achilles SU-14 2007?
For trailering, the Achilles SU-14 2007 has the edge at 28 lbs dry weight versus 167 lbs for the Achilles SGX-122 2013. 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.
Which boat can handle a bigger outboard?
The Achilles SU-14 2007 is rated to a maximum of 55 hp, giving it the larger power ceiling. The Achilles SGX-122 2013 tops out at 35 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Achilles SGX-122 2013 is Coast Guard rated for 6 passengers, while the Achilles SU-14 2007 is certified for 6. 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.
Which boat has the better power-to-weight ratio?
The Achilles SU-14 2007 has a better power-to-weight ratio at 1 lbs per hp compared to 5 lbs per hp for the Achilles SGX-122 2013. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Which boat is wider, and does it affect trailering?
The Achilles SU-14 2007 measures 71" wide, compared to 66" for the Achilles SGX-122 2013. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Are the Achilles SGX-122 2013 and Achilles SU-14 2007 from the same manufacturer?
Yes — both the Achilles SGX-122 2013 and the Achilles SU-14 2007 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.
