Achilles KSB-116 2007 vs Achilles RS-116 2012 — Same Brand, Different Boat

The Achilles KSB-116 2007 vs Achilles RS-116 2012 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.

On paper these two are close siblings in the size department — Achilles KSB-116 2007 at 11,0 ft versus Achilles RS-116 2012 at 11,5 ft. At 46 lbs and 75 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.

For family outings this is probably the sharpest distinction between the two. The Achilles RS-116 2012 is rated for 6 passengers, while the Achilles KSB-116 2007 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Achilles RS-116 2012 could be the deciding factor.

The Achilles RS-116 2012 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Achilles KSB-116 2007 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 RS-116 2012 if your priority is putting more people on the water — it handles 6 passengers and at 11,5 ft it has the deck room to back that rating up comfortably. The Achilles KSB-116 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.

Achilles KSB-116 2007 vs Achilles RS-116 2012 — Common Questions

Which is the larger boat — the Achilles KSB-116 2007 or the Achilles RS-116 2012?
The Achilles RS-116 2012 is the longer of the two at 11,5 feet overall. The Achilles KSB-116 2007 comes in at 11,0 feet, making it roughly 0,5 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Achilles KSB-116 2007 or the Achilles RS-116 2012?
For trailering, the Achilles KSB-116 2007 has the edge at 46 lbs dry weight versus 75 lbs for the Achilles RS-116 2012. 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.
How many people can each boat hold?
The Achilles KSB-116 2007 is Coast Guard rated for 3 passengers, while the Achilles RS-116 2012 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 RS-116 2012 measures 64" wide, compared to 37" for the Achilles KSB-116 2007. 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-116 2007 and Achilles RS-116 2012 from the same manufacturer?
Yes — both the Achilles KSB-116 2007 and the Achilles RS-116 2012 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.
