When two boats share the same hull type — in this case both the Achilles LSI-230 2009 and the Achilles RS-110 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 RS-110 2012 measures 11,0 feet overall (2012), giving it roughly 3,4 additional feet of deck space compared to the Achilles LSI-230 2009 at 7,6 feet (2009). At 52 lbs and 72 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 LSI-230 2009 carries a rated maximum of 4 hp. Engine data for the Achilles RS-110 2012 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-110 2012 is rated for 4 passengers, while the Achilles LSI-230 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 RS-110 2012 could be the deciding factor.
The Achilles RS-110 2012 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Achilles LSI-230 2009 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-110 2012 if your priority is putting more people on the water — it handles 4 passengers and at 11,0 ft it has the deck room to back that rating up comfortably. The Achilles LSI-230 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 2 that costs less to run day-to-day.
