A
vert ramp is any
half-pipe,
quarter-pipe, or structure similar thereto who's surface looks something like
y=
x2, only less circular and a little more
concave. The key
feature of this shape is that you are launched straight up allowing for a huge host of
aerial tricks to be performed with a
skateboard, a
BMX/
freestyle bike, a pair of
rollerblades, a
snowboard, a
wakeboard, or anything else with a smooth ride. (One day we'll use
hoverboards to combine snow, street, and water
boardsports.)
When building a vert ramp be sure to use a plumb to make sure the lip is parallel to the acceleration of gravity. If the construction isn't exact users of the ramp will not be able to test their vertical limit since getting too much air will land them on the deck, or worse.
