Matching a inflatable rigid Achilles HB-310 2008 against a inflatable non rigid Achilles RS-116 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.
Size is the most obvious dividing line here. The Achilles RS-116 2011 measures 11,5 feet overall (2011), giving it roughly 10,5 additional feet of deck space compared to the Achilles HB-310 2008 at 1,0 feet (2008). At 126 lbs and 75 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 Achilles HB-310 2008 carries a rated maximum of 15 hp. Engine data for the Achilles RS-116 2011 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.
For family outings this is probably the sharpest distinction between the two. The Achilles RS-116 2011 is rated for 6 passengers, while the Achilles HB-310 2008 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Achilles RS-116 2011 could be the deciding factor.
The Achilles RS-116 2011 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Achilles HB-310 2008 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 RS-116 2011 if your priority is putting more people on the water — it handles 6 passengers and at 11,5 ft it has the deck room to back that rating up comfortably. The Achilles HB-310 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
