OK, this has to be done on a flat down or a kinked box or rail – anything that has something you can air over before you slide. It’s fun and feels pretty damned good. You should be comfy with front boards before trying this.
To start out you probably want to find something without too big of a gap. It’s easier when the lip of the takeoff has a little bit of a kick; this helps you get over. Roll in flat based with your knees bent and enough speed to make the gap. You may want to just gap to 50-50 at first, to get comfy with the speed. It’s not fun to come up short (trust me, I know!) so go a little bit faster than what you think is the right speed.
Again, you want to be low with your knees bent and flat based. For a gap trick the pop is crucial so really snap off the tail, sucking up those legs and – as always– eyeballing the rail.
Once you’re over the gap, move your back foot over into the front boardslide position. You can do this in a few different ways; I like to have the rail under my front foot, but in between the bindings is also awesome, whatever floats your boat. As you land on the rail or box, get ready for a bit of impact. It’s essential you keep the board flat based as you don’t want to slip out or catch your edge.
Once on the rail, for added style you can try to bring your board round to 90 degrees or more, and counter rotate with your upper body so you’re looking down the rail in that classic front board position!
When you reach the end of the rail, bring the board back round to regular and bend your knees ready to stomp - this helps deal with compression if the landing is flat. Always stay looking at your landing. Put the board down, ride away and that’s gap to FS BS.
