Matching a inflatable non rigid Achilles KSB-116 2008 against a inflatable rigid Achilles SG-140 2008 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department — Achilles KSB-116 2008 at 11,0 ft versus Achilles SG-140 2008 at 14,0 ft. Weight tells a clearer story for trailering families: the Achilles SG-140 2008 tips the scales at 226 lbs — 180 lbs less than the Achilles KSB-116 2008 at 46 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 2008 tops out at 50 hp. Engine specs for the Achilles KSB-116 2008 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 2008 is rated for 6 passengers, while the Achilles KSB-116 2008 caps at 2. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Achilles SG-140 2008 could be the deciding factor.
Bottom line: Choose the Achilles SG-140 2008 if your priority is putting more people on the water — it handles 6 passengers and at 14,0 ft it has the deck room to back that rating up comfortably. The Achilles KSB-116 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 2 that costs less to run day-to-day.
