Walker Bay 240 AIR 2008 vs Walker Bay Generation 390 2011 - Boat Spec Comparison

Q: Which is the larger boat — the Walker Bay 240 AIR 2008 or the Walker Bay Generation 390 2011?

The Walker Bay Generation 390 2011 is the longer of the two at 12,8 feet overall. The Walker Bay 240 AIR 2008 comes in at 7,0 feet, making it roughly 5,8 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: Which is easier to trailer — the Walker Bay 240 AIR 2008 or the Walker Bay Generation 390 2011?

For trailering, the Walker Bay 240 AIR 2008 has the edge at 66 lbs dry weight versus 571 lbs for the Walker Bay Generation 390 2011. 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.

Q: Which boat can handle a bigger outboard?

The Walker Bay Generation 390 2011 is rated to a maximum of 50 hp, giving it the larger power ceiling. The Walker Bay 240 AIR 2008 tops out at 6 hp.

Q: How many people can each boat hold?

The Walker Bay 240 AIR 2008 is Coast Guard rated for 2 passengers, while the Walker Bay Generation 390 2011 is certified for 3. 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.

Q: Which boat has the better power-to-weight ratio?

The Walker Bay 240 AIR 2008 has a better power-to-weight ratio at 11 lbs per hp compared to 11 lbs per hp for the Walker Bay Generation 390 2011. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.

Q: Which boat is wider, and does it affect trailering?

The Walker Bay Generation 390 2011 measures 76" wide, compared to 6" for the Walker Bay 240 AIR 2008. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.

Q: Are the Walker Bay 240 AIR 2008 and Walker Bay Generation 390 2011 from the same manufacturer?

Yes — both the Walker Bay 240 AIR 2008 and the Walker Bay Generation 390 2011 are built by Walker Bay. 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.

Detailed Evaluation & Buyer Recommendation

Walker Bay 240 AIR 2008 vs Walker Bay Generation 390 2011 — Same Brand, Different Boat

Matching a foldable Walker Bay 240 AIR 2008 against a inflatable rigid Walker Bay Generation 390 2011 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The Walker Bay Generation 390 2011 measures 12,8 feet overall (2011), giving it roughly 5,8 additional feet of deck space compared to the Walker Bay 240 AIR 2008 at 7,0 feet (2008). Weight tells a clearer story for trailering families: the Walker Bay Generation 390 2011 tips the scales at 571 lbs — 505 lbs less than the Walker Bay 240 AIR 2008 at 66 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 50 hp, the Walker Bay Generation 390 2011 has a 44-hp advantage over the Walker Bay 240 AIR 2008's 6-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Walker Bay Generation 390 2011 is rated for 3 passengers, while the Walker Bay 240 AIR 2008 caps at 2. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Walker Bay Generation 390 2011 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Walker Bay 240 AIR 2008 comes in at 11 lbs per hp versus 11 lbs per hp for the Walker Bay Generation 390 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.

The Walker Bay 240 AIR 2008 has a documented top speed of 13 mph. Speed data wasn't available for the other model.

Bottom line: Choose the Walker Bay Generation 390 2011 if your priority is putting more people on the water — it handles 3 passengers and at 12,8 ft it has the deck room to back that rating up comfortably. The Walker Bay 240 AIR 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 2 that costs less to run day-to-day.
