Both the Walker Bay Generation 360 2013 and the Walker Bay Generation 390 2011 are rigid inflatable designs, both built in rigid inflatable, so 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 - Walker Bay Generation 360 2013 at 11,9 ft versus Walker Bay Generation 390 2011 at 12,8 ft. At 487 lbs and 571 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 - 40 hp for the Walker Bay Generation 360 2013 and 50 hp for the Walker Bay Generation 390 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. Fuel capacity breaks the other way: the Walker Bay Generation 390 2011 carries 16 gallons versus 11 gallons in the Walker Bay Generation 360 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Walker Bay Generation 360 2013 is rated for 5 passengers, while the Walker Bay Generation 390 2011 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Walker Bay Generation 360 2013 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Walker Bay Generation 390 2011 comes in at 11 lbs per hp versus 12 lbs per hp for the Walker Bay Generation 360 2013. 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.
