When two boats share the same hull type — in this case both the Achilles LEX-88 2012 and the Achilles LS2-RU 2010 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 LEX-88 2012 at 8,7 ft versus Achilles LS2-RU 2010 at 7,5 ft. At 69 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 — 6 hp for the Achilles LEX-88 2012 and 4 hp for the Achilles LS2-RU 2010. 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.

For family outings this is probably the sharpest distinction between the two. The Achilles LEX-88 2012 is rated for 4 passengers, while the Achilles LS2-RU 2010 caps at 2. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Achilles LEX-88 2012 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Achilles LEX-88 2012 comes in at 12 lbs per hp versus 14 lbs per hp for the Achilles LS2-RU 2010. 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 LEX-88 2012 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Achilles LS2-RU 2010 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
