Achilles LEX-77 2007 vs Achilles LS2-RU 2011 — Same Brand, Different Boat

The Achilles LEX-77 2007 vs Achilles LS2-RU 2011 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 LEX-77 2007 at 7,0 ft versus Achilles LS2-RU 2011 at 7,5 ft. At 62 lbs and 56 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.

Both boats share a closely matched power ceiling — 4 hp for the Achilles LEX-77 2007 and 4 hp for the Achilles LS2-RU 2011. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.

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.

At this size, power-to-weight ratio matters more than outright horsepower. The Achilles LS2-RU 2011 comes in at 14 lbs per hp versus 16 lbs per hp for the Achilles LEX-77 2007. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

The Achilles LS2-RU 2011 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Achilles LEX-77 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 LEX-77 2007 and Achilles LS2-RU 2011 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 LEX-77 2007 vs Achilles LS2-RU 2011 — Common Questions

Which is the larger boat — the Achilles LEX-77 2007 or the Achilles LS2-RU 2011?
The Achilles LS2-RU 2011 is the longer of the two at 7,5 feet overall. The Achilles LEX-77 2007 comes in at 7,0 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 LEX-77 2007 or the Achilles LS2-RU 2011?
For trailering, the Achilles LS2-RU 2011 has the edge at 56 lbs dry weight versus 62 lbs for the Achilles LEX-77 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.
How many people can each boat hold?
The Achilles LEX-77 2007 is Coast Guard rated for 2 passengers, while the Achilles LS2-RU 2011 is certified for 2. 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 has the better power-to-weight ratio?
The Achilles LS2-RU 2011 has a better power-to-weight ratio at 14 lbs per hp compared to 16 lbs per hp for the Achilles LEX-77 2007. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Which boat is wider, and does it affect trailering?
The Achilles LEX-77 2007 measures 57" wide, compared to 52" for the Achilles LS2-RU 2011. 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 LEX-77 2007 and Achilles LS2-RU 2011 from the same manufacturer?
Yes — both the Achilles LEX-77 2007 and the Achilles LS2-RU 2011 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.
