When two boats share the same hull type — in this case both the Achilles RV-110 2013 and the Achilles SG-140 2013 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 RV-110 2013 at 11,0 ft versus Achilles SG-140 2013 at 14,0 ft. Weight tells a clearer story for trailering families: the Achilles SG-140 2013 tips the scales at 226 lbs — 144 lbs less than the Achilles RV-110 2013 at 82 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 SG-140 2013 tops out at 50 hp. Engine specs for the Achilles RV-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 SG-140 2013 is rated for 6 passengers, while the Achilles RV-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 SG-140 2013 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 RV-110 2013 vs 18 in. (45 cm) on the Achilles SG-140 2013 — larger tubes generally mean more buoyancy and a drier, more stable ride.
