Achilles LSI-290 2008 vs Achilles RS-116 2006 — Same Brand, Different Boat

The Achilles LSI-290 2008 vs Achilles RS-116 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.

On paper these two are close siblings in the size department — Achilles LSI-290 2008 at 9,0 ft versus Achilles RS-116 2006 at 11,0 ft. At 74 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.

The Achilles LSI-290 2008 carries a rated maximum of 8 hp. Engine data for the Achilles RS-116 2006 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.

For family outings this is probably the sharpest distinction between the two. The Achilles LSI-290 2008 is rated for 4 passengers, while the Achilles RS-116 2006 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Achilles LSI-290 2008 could be the deciding factor.

Bottom line: Choose the Achilles LSI-290 2008 if your priority is putting more people on the water — it handles 4 passengers and at 9,0 ft it has the deck room to back that rating up comfortably. The Achilles RS-116 2006 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 LSI-290 2008 vs Achilles RS-116 2006 — Common Questions

Which is the larger boat — the Achilles LSI-290 2008 or the Achilles RS-116 2006?
The Achilles RS-116 2006 is the longer of the two at 11,0 feet overall. The Achilles LSI-290 2008 comes in at 9,0 feet, making it roughly 2,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Achilles LSI-290 2008 or the Achilles RS-116 2006?
For trailering, the Achilles LSI-290 2008 has the edge at 74 lbs dry weight versus 75 lbs for the Achilles RS-116 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 LSI-290 2008 has a documented max rating of 8 hp. Engine specifications for the Achilles RS-116 2006 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 LSI-290 2008 is Coast Guard rated for 4 passengers, while the Achilles RS-116 2006 is certified for 3. 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 2006 measures 64" wide, compared to 62" for the Achilles LSI-290 2008. 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 LSI-290 2008 and Achilles RS-116 2006 from the same manufacturer?
Yes — both the Achilles LSI-290 2008 and the Achilles RS-116 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.
