Matching a inflatable rigid Achilles HB-350DX 2008 against a inflatable non rigid Achilles RV-156 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 RV-156 2009 measures 15,5 feet overall (2009), giving it roughly 4,5 additional feet of deck space compared to the Achilles HB-350DX 2008 at 11,0 feet (2008). Weight tells a clearer story for trailering families: the Achilles RV-156 2009 tips the scales at 165 lbs — 163 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.
The Achilles HB-350DX 2008 carries a rated maximum of 30 hp. Engine data for the Achilles RV-156 2009 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 RV-156 2009 is rated for 12 passengers, while the Achilles HB-350DX 2008 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Achilles RV-156 2009 could be the deciding factor.
Bottom line: Choose the Achilles RV-156 2009 if your priority is putting more people on the water — it handles 12 passengers and at 15,5 ft it has the deck room to back that rating up comfortably. The Achilles HB-350DX 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
