Q. I keep seeing people say "Double-up " and I am not quite sure what that is... Can someone describe it?
A. The double up is when the boat driver makes a wide turn and circles back around into the wake at a 90 degree angle. When the old wake meets the new wake, the wake becomes twice as large, thus the name double up. The rider should try to time the spot when the wakes meet and jump off that spot. It is a great way to get a lot of air and try new tricks.

Q. What's a good boat speed for Wakeboarding?
A. Generally speaking, beginners start out at around 28-30 km/h. That's a good speed to become familiar with the wakeboard while learning to control and maneuver it. This speed is also slow enough that you don't experience much drag, yet fast enough for you to practice cutting over the wake and moving into surface 180's and surface 360's.
As you improve and feel more confident, you can speed up to anywhere between 33-38 km/h. Keep in mind, a lot of this is dictated by your individual size, the boat's wake, rope length, and, of course, your comfort level.
