Achilles LSI-122 2007 vs Achilles RS-116 2012 — Same Brand, Different Boat

The Achilles LSI-122 2007 vs Achilles RS-116 2012 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — Achilles LSI-122 2007 at 12,0 ft versus Achilles RS-116 2012 at 11,5 ft. At 113 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 LSI-122 2007 carries a rated maximum of 25 hp. Engine data for the Achilles RS-116 2012 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.

Both boats are rated for 6 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 RS-116 2012 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Achilles LSI-122 2007 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.

Bottom line: The Achilles LSI-122 2007 and Achilles RS-116 2012 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

Achilles LSI-122 2007 vs Achilles RS-116 2012 — Common Questions

Which is the larger boat — the Achilles LSI-122 2007 or the Achilles RS-116 2012?
The Achilles LSI-122 2007 is the longer of the two at 12,0 feet overall. The Achilles RS-116 2012 comes in at 11,5 feet, making it roughly 0,5 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Achilles LSI-122 2007 or the Achilles RS-116 2012?
For trailering, the Achilles RS-116 2012 has the edge at 75 lbs dry weight versus 113 lbs for the Achilles LSI-122 2007. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
What is the maximum horsepower rating for these boats?
The Achilles LSI-122 2007 has a documented max rating of 25 hp. Engine specifications for the Achilles RS-116 2012 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.
How many people can each boat hold?
The Achilles LSI-122 2007 is Coast Guard rated for 6 passengers, while the Achilles RS-116 2012 is certified for 6. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Achilles LSI-122 2007 measures 66" wide, compared to 64" for the Achilles RS-116 2012. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Are the Achilles LSI-122 2007 and Achilles RS-116 2012 from the same manufacturer?
Yes — both the Achilles LSI-122 2007 and the Achilles RS-116 2012 are built by Achilles. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
