Matching a inflatable rigid Achilles HB-350DX 2008 against a inflatable non rigid Achilles SG-140 2010 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 2008 at 11,0 ft versus Achilles SG-140 2010 at 14,0 ft. Weight tells a clearer story for trailering families: the Achilles SG-140 2010 tips the scales at 226 lbs — 224 lbs less than the Achilles HB-350DX 2008 at 2 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 — 30 hp for the Achilles HB-350DX 2008 and 50 hp for the Achilles SG-140 2010. 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 HB-350DX 2008 comes in at 0 lbs per hp versus 5 lbs per hp for the Achilles SG-140 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: The Achilles SG-140 2010 at 14,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Achilles HB-350DX 2008 at 11,0 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.
