The technique of riding an unbroken wave by traveling along its length as well as running shore wards is fundamental to surfing in any craft. It is called a diagonal run.
Get the kayak surfing and then turn away from the break and tilt the craft with your hips into the wave to allow the edge (or rail), to grip the water. Twist the upper body towards the beach and apply a low-brace rudder on the down-wave (beach) side, pressing the stern into the wave to keep the nose down and pointing along the wave. With any luck you will be positioned on the wave in the power pocket with the broken wall of water (the shoulder) chasing behind you.
Once performing a diagonal run, you can alter the angle of the kayak to face down wave by leaning down the wave and asserting pressure on the low-brace rudder. To alter the angle of the kayak to face up wave lean the kayak up wave and release pressure from the low-brace rudder.
This technique forms the basics for all surfing maneuvers. To achieve the more complex maneuvers the low brace rudder may be applied on the up wave side and the kayak may need to be leaned to some quite impossible angles.
As mentioned above the diagonal run is the basic surfing position from which all maneuvers can be performed. From this position the surfer planing along unbroken sections of a wave can trim the kayak to maintain or increase speed, which is essential in all maneuvers. This results in the diagonal run, not being quite a dead straight one.
Upon reaching the base of a wave the bottom turn produces the direction change and acceleration necessary to climb to the wave's crest. This maneuver will be performed immediately after a straight take-off, enabling the surfer to climb back up the wave into a position to perform a diagonal run. It can also be used to negotiate a fast or breaking section, allowing the surfer to surf down and around the white water and regain the shoulder beyond.
The top turn is used to change direction after climbing to the uppermost section of a wave. When at the top of the wave the surfer is in danger of stalling and sliding off the back of the wave. To avoid this the surfer needs to lean forward to ensure that the kayak completes the maneuver. The top turn can also be used as a stall technique for regaining the power pocket.
Climbing and Dropping
Climbing and dropping is the sequence of combining top and bottom turns. With each sequence the surfer increases speed to facilitate further maneuvers.
The Cut Back
The cut back allows the surfer to change the direction of the diagonal run through 180 degrees. This is done by turning the kayak down the wave and continuing the turn until the kayak is facing the direction from where it came.
The cut back is usually performed upon reaching a slower section of a wave whereby the surfer changes his direction 180 degrees back towards the pursuing white water thereby regaining the pocket.
Roundhouse Cut Back
In the description above the cut back was performed by the surfer traveling away from the shoulder. It can also be performed when planing towards the shoulder, so as to return to the position of the diagonal run.
When two cut back turns are performed in succession, the first towards the shoulder and the second away from the shoulder, this maneuver is known as a roundhouse cut back.
This modification of the top turn is performed as the surfer travels steeply up the face of the wave, where upon the surfer performs a flamboyant turn through almost 180o where the tail of the kayak will slash across the top of the wave.
This top turn is performed right on the lip (crest) of the wave, using the power of wave to turn the kayak.
When running towards the shoulder, following a cut back or faded take off, the surfer can continue the run right into the broken section of the wave, using the force of the white water to turn the kayak and bounce back into the power pocket.
Whilst planing a fast section of an unbroken wave the surfer can perform either a bottom or top turn and then releasing the forward rail causing the kayak to slide sideways in the original direction of the run. The side slide can be used as a means of stalling, thus allowing the shoulder to catch up.
The side slide can also be used as a means of dropping to the bottom of a wave. The boat control and technique required for a side slide is similar to that required by a floater.
On occasions when racing along a wall, a section of white water will break in front of you. This necessitates turning in a long arc around the base of the white water (a big bottom top), or alternatively, climbing up and floating over the top of the foam before roller-coasting back down on to the unbroken water.
Having ascended to the crest of a breaking wave it is possible to re-enter, turning back toward the base of the wave, using the crumbling/pitching lip as a power source to aid redirection: yet another functional method of keeping near the power pocket.
The re-entry can be used as a close-out maneuver when performed an approaching shoulder. Enabling the surfer to travel to the base of the wave away from the crashing white water as the last portion of the wave breaks.
In the right conditions it is possible to extend a re-entry to the point of leaving contact with the wave crest, allowing the surfer to turn in mid-air.
Like the re-entry the aerial can also be used as a close-out maneuver by the surfer using the power of the approaching shoulder to aid redirection to the base of the wave.
In a kayak the 360° is performed as a flat spin. It is initiated by forcing the tail of the kayak to slide down the wave and around so as to cause the kayak to be planing backwards. Once this point is achieved the paddler then repeats the process, by forcing the nose of the kayak to slide down the wave and around, returning the kayak to a forward planing direction.
This maneuver may be deemed dangerous both for the kayaker and other water users, but it can be a flamboyant functional maneuver. A typical application of the 360° is as a stalling maneuver performed on the face of the wave whilst waiting for the shoulder, as an alternative to the cutback .
Other applications of the 360° are as part of a top turn, part of floater or as a regain 360°.
The 360° is initiated by sliding the tail of the kayak down the wave. With the reverse 360° the turn is initiated with the nose of the kayak turning down the wave. An all together harder maneuver.
There are occasions, when riding steep-walled waves where the rider is confronted with a section that is impossible to negotiate, other than to trim underneath the throwing lip, and ride the very inside of the wave. Tube riding is sometimes referred to as getting covered.
When the wave finally closes out and there is no more unbroken wave to plane along the surfer needs to finish the ride by performing an end maneuver. At times it may even be necessary to finish the ride prematurely, due to the particular circumstances at the time (obstacles such as rocks, piers or other water users).
The simplest way to pull off a wave, is to turn up wave and climb up and over the back before the whole thing collapses and becomes a heaving mass of soup.
On occasion it is not possible to exit over the top of the wave, forcing the rider to either straighten out and ride the white water, or punch through the wave - the punch out.
The alternative to pulling off the back of the wave is to straighten up and use the white water to perform an end maneuver unique to kayaks. The easiest of these maneuvers are the loop and pop-out.
Loop and Pop-Out
By continuing to lean forwards as the breaking wave lifts the back of the boat, the nose will dig in. As the wave continues forwards the tail will rise and as the wave passes the now vertical kayak the volume in the bow that is displaced under water will cause the kayak to shoot upwards. It is possible for the nose of the kayak to clear the water, when this happens it is called a sky rocket.
If the tail of the boat travels over the nose of the boat in the vertical plane, causing the paddler to land in a capsized position, then a loop has been performed. If however, the tail doesn't pass vertically over the nose of the kayak, but instead returns to its original position a pop-out has been performed.
It is possible through body positioning to control these end maneuvers. By leaning the body forwards you are more likely to perform a loop. If you lean back whilst vertical you are more likely to perform a pop-out. By the use of body rotation, when vertical, the kayak can be spun on its vertical axis, thus enabling the performance of dry loops and pirouettes.
Having forced the kayak into a vertical position, the kayak can be spun on its vertical axis. A 180° degree spin as part of a loop is termed a dry loop. A 360° degree spin or even a 720° degree spin is known as a pirouette.
The cart wheel is performed as a means of a forward and then reverse loop on the same wave. The trick with the cart wheel is to land the kayak after the first forward dry loop in front of the wave in a position where a reverse loop can then be performed.
