When two boats share the same hull type — in this case both the Achilles KSB-116 2008 and the Achilles LS2-RU 2012 are inflatable non rigid designs with inflatable construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
Size is the most obvious dividing line here. The Achilles KSB-116 2008 measures 11,0 feet overall (2008), giving it roughly 3,5 additional feet of deck space compared to the Achilles LS2-RU 2012 at 7,5 feet (2012). At 46 lbs and 57 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 LS2-RU 2012 tops out at 4 hp. Engine specs for the Achilles KSB-116 2008 aren't listed — confirm with a dealer before selecting an outboard.
Both boats are rated for 2 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.
The Achilles LS2-RU 2012 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Achilles KSB-116 2008 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
Bottom line: The Achilles KSB-116 2008 at 11,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Achilles LS2-RU 2012 at 7,5 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.
