Matching a inflatable rigid Achilles HB-350LX 2010 against a inflatable non rigid Achilles LS2-RU 2009 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.

Size is the most obvious dividing line here. The Achilles HB-350LX 2010 measures 11,5 feet overall (2010), giving it roughly 4,0 additional feet of deck space compared to the Achilles LS2-RU 2009 at 7,5 feet (2009). Weight tells a clearer story for trailering families: the Achilles HB-350LX 2010 tips the scales at 161 lbs — 105 lbs more than the Achilles LS2-RU 2009 at 56 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 — 20 hp for the Achilles HB-350LX 2010 and 4 hp for the Achilles LS2-RU 2009. 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.

For family outings this is probably the sharpest distinction between the two. The Achilles HB-350LX 2010 is rated for 6 passengers, while the Achilles LS2-RU 2009 caps at 2. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Achilles HB-350LX 2010 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Achilles HB-350LX 2010 comes in at 8 lbs per hp versus 14 lbs per hp for the Achilles LS2-RU 2009. 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.
