Achilles RS-110 2009 vs Achilles SPD-104 2007 — Same Brand, Different Boat

The Achilles RS-110 2009 vs Achilles SPD-104 2007 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 RS-110 2009 measures 11,0 feet overall (2009), giving it roughly 10,0 additional feet of deck space compared to the Achilles SPD-104 2007 at 1,0 feet (2007). At 72 lbs and 96 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 SPD-104 2007 tops out at 10 hp. Engine specs for the Achilles RS-110 2009 aren't listed — confirm with a dealer before selecting an outboard.

Both boats are rated for 4 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Achilles RS-110 2009 at 11,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Achilles SPD-104 2007 at 1,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.

Achilles RS-110 2009 vs Achilles SPD-104 2007 — Common Questions

Which is the larger boat — the Achilles RS-110 2009 or the Achilles SPD-104 2007?
The Achilles RS-110 2009 is the longer of the two at 11,0 feet overall. The Achilles SPD-104 2007 comes in at 1,0 feet, making it roughly 10,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Achilles RS-110 2009 or the Achilles SPD-104 2007?
For trailering, the Achilles RS-110 2009 has the edge at 72 lbs dry weight versus 96 lbs for the Achilles SPD-104 2007. 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 SPD-104 2007 has a documented max rating of 10 hp. Engine specifications for the Achilles RS-110 2009 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 RS-110 2009 is Coast Guard rated for 4 passengers, while the Achilles SPD-104 2007 is certified for 4. 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.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Achilles RS-110 2009 and Achilles SPD-104 2007 share an 5 ft. 2 in. (157 cm) beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Are the Achilles RS-110 2009 and Achilles SPD-104 2007 from the same manufacturer?
Yes — both the Achilles RS-110 2009 and the Achilles SPD-104 2007 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.
