Achilles KSB-94 2011 vs Achilles SG-140 2006 — Same Brand, Different Boat

The Achilles KSB-94 2011 vs Achilles SG-140 2006 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.

Size is the most obvious dividing line here. The Achilles SG-140 2006 measures 14,0 feet overall (2006), giving it roughly 4,7 additional feet of deck space compared to the Achilles KSB-94 2011 at 9,3 feet (2011). Weight tells a clearer story for trailering families: the Achilles SG-140 2006 tips the scales at 237 lbs — 200 lbs less than the Achilles KSB-94 2011 at 37 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 2006 tops out at 50 hp. Engine specs for the Achilles KSB-94 2011 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 2006 is rated for 6 passengers, while the Achilles KSB-94 2011 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Achilles SG-140 2006 could be the deciding factor.

The Achilles KSB-94 2011 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Achilles SG-140 2006 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.

Bottom line: Choose the Achilles SG-140 2006 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-94 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.

Achilles KSB-94 2011 vs Achilles SG-140 2006 — Common Questions

Which is the larger boat — the Achilles KSB-94 2011 or the Achilles SG-140 2006?
The Achilles SG-140 2006 is the longer of the two at 14,0 feet overall. The Achilles KSB-94 2011 comes in at 9,3 feet, making it roughly 4,7 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Achilles KSB-94 2011 or the Achilles SG-140 2006?
For trailering, the Achilles KSB-94 2011 has the edge at 37 lbs dry weight versus 237 lbs for the Achilles SG-140 2006. 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.
What is the maximum horsepower rating for these boats?
The Achilles SG-140 2006 has a documented max rating of 50 hp. Engine specifications for the Achilles KSB-94 2011 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.
How many people can each boat hold?
The Achilles KSB-94 2011 is Coast Guard rated for 1 passengers, while the Achilles SG-140 2006 is certified for 6. 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 is wider, and does it affect trailering?
The Achilles SG-140 2006 measures 69" wide, compared to 37" for the Achilles KSB-94 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 KSB-94 2011 and Achilles SG-140 2006 from the same manufacturer?
Yes — both the Achilles KSB-94 2011 and the Achilles SG-140 2006 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.
