The Walker Bay 270 AIR 2006 vs Walker Bay 310 RTD/RTDH 2008 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 Walker Bay 270 AIR 2006 measures 8,0 feet overall (2006), giving it roughly 7,0 additional feet of deck space compared to the Walker Bay 310 RTD/RTDH 2008 at 1,0 feet (2008). At 7 lbs and 14 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 — 8 hp for the Walker Bay 270 AIR 2006 and 15 hp for the Walker Bay 310 RTD/RTDH 2008. 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 Walker Bay 310 RTD/RTDH 2008 comes in at 1 lbs per hp versus 1 lbs per hp for the Walker Bay 270 AIR 2006. 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.
The Walker Bay 310 RTD/RTDH 2008 has a documented top speed of 22 mph. Speed data wasn't available for the other model.
Bottom line: The Walker Bay 270 AIR 2006 at 8,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Walker Bay 310 RTD/RTDH 2008 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.
