Over the years, the wakesurf premise has stayed the same — get up on the board while holding a short ski line, find the sweet spot in the wake, and toss the line back into the boat. At the right boat speed, the wake has enough energy to keep board and rider moving forward. Fresh interest in wakesurfing started eight or 10 years ago, enabled by the development of the wakeboarding tow boat, an inboard with water ballast designed to make a very large wake. Slow that boat down to 10 or 12 mph, and a wake with surfable energy is created right off the transom. With hints of a recession looming and wakeboarding perhaps peaking in popularity, the tow-sports industry threw product and marketing energy behind wakesurfing, hoping it could be The Next Big Thing. Dedicated wakesurfing boards were developed, and boatbuilders started adding trim tabs and other details to tow boats to enhance the shape of the wake at surf speed. A dialed-in wakesurfer can ride the wave until the boat runs out of gas, and surfing doesn't hurt when you fall off, knee ligaments stay intact, and a buddy can film you from the boat.
