Matching a inflatable rigid Achilles HB-350DX 2009 against a inflatable non rigid Achilles SU-14 2013 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 2009 at 11,5 ft versus Achilles SU-14 2013 at 14,0 ft. At 2 lbs and 28 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 55 hp, the Achilles SU-14 2013 has a 25-hp advantage over the Achilles HB-350DX 2009'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 HB-350DX 2009 comes in at 0 lbs per hp versus 1 lbs per hp for the Achilles SU-14 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 SU-14 2013 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Achilles HB-350DX 2009 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
Bottom line: The Achilles SU-14 2013 at 14,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Achilles HB-350DX 2009 at 11,5 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
