In the process of dialing in my X-25 wave. These are at about 11 mph with center and port tanks full, about 650 pounds (Pop bags and sac) in left rear locker (in addition to the tank), and about 1000 pounds (1200 bag almost full) in the locker under the port side lounge seat. Wake plate at 40%. No surf tabs. Just me in the boat. Makes a nice long pocket with good push.
