The listing states a 650 lb maximum. Under the 70 percent rule, total load (rider plus anything on the deck) should stay at or below about 454 lb for the board to ride at its designed waterline. That puts the comfortable solo rider range at up to about 444 lb with 10 lb of gear.
At 31 inches wide it suits beginner to intermediate riders under about 200 lb. Our paddle board size calculator puts a 180 lb beginner at 32 inches and a 250 lb beginner at 34.
By its dimensions it holds about 329 L of air. Pumping to 15 PSI takes roughly 11 minutes on a single-action hand pump.
