Matching a inflatable non rigid Achilles SGX-132 2010 against a inflatable rigid Achilles SU-16 2008 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department — Achilles SGX-132 2010 at 13,2 ft versus Achilles SU-16 2008 at 16,0 ft. Weight tells a clearer story for trailering families: the Achilles SU-16 2008 tips the scales at 378 lbs — 166 lbs less than the Achilles SGX-132 2010 at 212 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 75 hp, the Achilles SU-16 2008 has a 35-hp advantage over the Achilles SGX-132 2010's 40-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Achilles SU-16 2008 is rated for 9 passengers, while the Achilles SGX-132 2010 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Achilles SU-16 2008 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Achilles SU-16 2008 comes in at 5 lbs per hp versus 5 lbs per hp for the Achilles SGX-132 2010. 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 Achilles SU-16 2008 if your priority is putting more people on the water — it handles 9 passengers and at 16,0 ft it has the deck room to back that rating up comfortably. The Achilles SGX-132 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
