When two boats share the same hull type — in this case both the Achilles LT-2 2012 and the Achilles SU-16 2010 are inflatable non rigid designs with inflatable construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
Size is the most obvious dividing line here. The Achilles SU-16 2010 measures 16,0 feet overall (2010), giving it roughly 8,8 additional feet of deck space compared to the Achilles LT-2 2012 at 7,3 feet (2012). Weight tells a clearer story for trailering families: the Achilles SU-16 2010 tips the scales at 378 lbs — 341 lbs less than the Achilles LT-2 2012 at 37 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 2010 has a 72-hp advantage over the Achilles LT-2 2012's 3-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 2010 is rated for 9 passengers, while the Achilles LT-2 2012 caps at 2. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Achilles SU-16 2010 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Achilles SU-16 2010 comes in at 5 lbs per hp versus 12 lbs per hp for the Achilles LT-2 2012. 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 LT-2 2012 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Achilles SU-16 2010 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
Bottom line: Choose the Achilles SU-16 2010 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 LT-2 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 2 that costs less to run day-to-day.
