When two boats share the same hull type — in this case both the Achilles RS-116 2009 and the Achilles SPD-365 2013 are inflatable non rigid designs with inflatable construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department — Achilles RS-116 2009 at 11,5 ft versus Achilles SPD-365 2013 at 12,2 ft. At 75 lbs and 142 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-365 2013 tops out at 25 hp. Engine specs for the Achilles RS-116 2009 aren't listed — confirm with a dealer before selecting an outboard.

Both boats are rated for 6 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.

The Achilles SPD-365 2013 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Achilles RS-116 2009 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
