When two boats share the same hull type — in this case both the Achilles RS-110 2013 and the Achilles SGX-132 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?

On paper these two are close siblings in the size department — Achilles RS-110 2013 at 11,0 ft versus Achilles SGX-132 2012 at 13,2 ft. Weight tells a clearer story for trailering families: the Achilles SGX-132 2012 tips the scales at 187 lbs — 115 lbs less than the Achilles RS-110 2013 at 72 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The Achilles SGX-132 2012 tops out at 40 hp. Engine specs for the Achilles RS-110 2013 aren't listed — confirm with a dealer before selecting an outboard.

For family outings this is probably the sharpest distinction between the two. The Achilles SGX-132 2012 is rated for 6 passengers, while the Achilles RS-110 2013 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Achilles SGX-132 2012 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: 16 in. (41 cm) on the Achilles RS-110 2013 vs 18 in. (45 cm) on the Achilles SGX-132 2012 — larger tubes generally mean more buoyancy and a drier, more stable ride.
