When two boats share the same hull type — in this case both the Achilles LSI-335 2011 and the Achilles RV-110 2011 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?
On paper these two are close siblings in the size department — Achilles LSI-335 2011 at 11,0 ft versus Achilles RV-110 2011 at 11,0 ft. At 91 lbs and 82 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-335 2011 carries a rated maximum of 15 hp. Engine data for the Achilles RV-110 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 LSI-335 2011 is rated for 5 passengers, while the Achilles RV-110 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Achilles LSI-335 2011 could be the deciding factor.
Both are inflatable designs, which means they pack down for compact storage, can be carried in a bag, and are dramatically lighter than equivalent rigid hulls. The trade-off is setup time and the need to monitor tube pressure regularly. Tube diameter differs: 18 in. (45 cm) on the Achilles LSI-335 2011 vs 16 in. (41 cm) on the Achilles RV-110 2011 — larger tubes generally mean more buoyancy and a drier, more stable ride.
Bottom line: Choose the Achilles LSI-335 2011 if your priority is putting more people on the water — it handles 5 passengers and at 11,0 ft it has the deck room to back that rating up comfortably. The Achilles RV-110 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
