Matching a inflatable rigid Achilles HB-350DX 2012 against a inflatable non rigid Achilles SU-14 2011 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 HB-350DX 2012 at 11,5 ft versus Achilles SU-14 2011 at 14,0 ft. Weight tells a clearer story for trailering families: the Achilles HB-350DX 2012 tips the scales at 187 lbs — 159 lbs more than the Achilles SU-14 2011 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.

The power gap is worth calling out. Rated to 55 hp, the Achilles SU-14 2011 has a 25-hp advantage over the Achilles HB-350DX 2012's 30-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

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 2011 comes in at 1 lbs per hp versus 6 lbs per hp for the Achilles HB-350DX 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.

Both are inflatable designs, which means they pack down for compact storage, can be carried in a bag, and are dramatically lighter than equivalent rigid hulls. The trade-off is setup time and the need to monitor tube pressure regularly. Tube diameter differs: 18 in. (45 cm) on the Achilles HB-350DX 2012 vs 19 in. (48 cm) on the Achilles SU-14 2011 — larger tubes generally mean more buoyancy and a drier, more stable ride.
