section. Airs can either be straight airs or rotational airs. Straight airs have minimal rotation if any, but definitely no more rotation than 90 degrees. Rotational airs require a rotation of 90 degrees or more depending on the level of the surfer. Types of rotations: 180 degrees – called an air reverse, this is when the surfer spins enough to land backwards, then reverts to their original positional with the help of the fins. This rotation can either be done frontside or backside and can spin right or left. 360 degrees – this is a full rotation air or “full rotor” where the surfer lands where they started or more, as long as they do not land backwards. When this is achieved front side on a wave spinning the opposite of an air reverse is called an alley-oop. 540 degrees – the surfer does a full rotation plus another 180 degrees and can be inverted or spinning straight, few surfers have been able to land this air. Backflip – usually done with a double grab, this hard to land air is made for elite-level surfers. Rodeo flip – usually done backside, it is a backflip with a 180 rotation, and is actually easier than a straight backflip. Grabs – a surfer can help land an aerial maneuver by grabbing the surfboard, keeping them attached to the board and keeping the board under their feet. Common types of grabs include: Indy – a grab on the surfers inside rail going frontside, outside rail going backside with their backhand. Slob – a grab on the surfers inside rail going frontside, outside rail going backside with their front hand. Lien – A grab on the surfers outside rail frontside, inside rail going backside with their front hand. Stalefish – A grab on the surfers outside rail frontside, inside rail backside with their backhand. Double grab – A grab on the surfers inside and outside rail, the inside rail with the backhand and the outside rail with the front hand.
