The Mercury 270 Air Deck Gray (PVC) 2006 vs Mercury 310 Sport PVC 2011 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 — Mercury 270 Air Deck Gray (PVC) 2006 at 8,0 ft versus Mercury 310 Sport PVC 2011 at 10,2 ft. At 79 lbs and 122 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.
Both boats share a closely matched power ceiling — 10 hp for the Mercury 270 Air Deck Gray (PVC) 2006 and 15 hp for the Mercury 310 Sport PVC 2011. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.
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.
At this size, power-to-weight ratio matters more than outright horsepower. The Mercury 270 Air Deck Gray (PVC) 2006 comes in at 8 lbs per hp versus 8 lbs per hp for the Mercury 310 Sport PVC 2011. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Bottom line: The Mercury 310 Sport PVC 2011 at 10,2 ft is the right call if deck space, comfort, and entertaining are top of your list. The Mercury 270 Air Deck Gray (PVC) 2006 at 8,0 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.
