Remember that your eyes may deceive you when scoping out the rollers from a distance. The largest roller you can see is actually roller number two. To really connect with the double-up, time it so you end up in the trough immediately before the roller you want to hit. For example, if you want to hit roller number two, find the largest roller you can see as the boat crosses the rollers, and then time your approach so you end up in the deepest part of the trough immediately before roller number two. At that point, the double-up will swell beneath you and propel you into the stratosphere, just like it did for Rusty in the photo. Have fun!
