1

Demostrar de manera satisfactoria al examinador que tiene conocimiento de las distintas clases de kayaks (Slalom, ríos, turismo, mar), los usos de cada uno y el equipo necesario para la seguridad en los kayaks (casco, chaleco salvavidas, faldón, lazada de la proa y popa, equipo de flotación para kayaks).

Kayak Types

Slalom Kayak

These are used in slalom racing. A slalom race takes place on a whitewater course, and the kayaker must maneuver the kayak between several pairs of poles called "gates". Green-colored gates must be entered by paddling downstream, and red-colored gates must be entered by paddling upstream. The minimum length of a slalom kayak is four meters, and the minimum width is 60 cm. Slalom kayaks are usually built out of fiberglass or composite materials. Light weight is a very desirable characteristic in these boats.

Equipment

Helmet

A helmet should be worn any time a kayak is taken into whitewater. Whitewater is "white" because of rocks, and have the potential to seriously injure a person. The greatest danger addressed by a helmet is that of striking the head on an underwater obstacle when overturned in fast moving current.

Demostrar la capacidad de entrar y salir de un kayak:

The first step in all of these is to make sure you're wearing a lifejacket. If you're going to paddle in swift water, put on your sprayskirt and helmet too.

2a

De una playa

Exit: Paddle onto the beach until the kayak stops. Place your paddle across the front of the cockpit, pop the sprayskirt (if you're using one) and use your arms to lift your bottom out of the boat. Sit on the rear cockpit rim, lift your knees and extract your legs. Stand up, grab the kayak, and drag it further on shore. Once you remove the weight of your body from the kayak, it will likely begin to float again, so if you don't pull it further onto shore, it may very well float away in the current.

2b

Desde un muelle o desembarque

Entry:

Put the kayak in the water alongside the pier and lay the paddle on the pier where you will be able to reach it once you're in the boat. Sit on the pier and put your feet in the kayak, then turn your body towards the front of the boat and place both hands on the pier right next to one another. Gently stand in the kayak while dividing your weight between your feet and your hands. Bend the knees and lower yourself into the kayak while still holding on to the dock. Work you knees into the cockpit, let go of the dock, and grab the paddle. If you're using a sprayskirt, attach it to the cockpit.

Exit:

Paddle alongside the dock, place your paddle on the dock, and pop the sprayskirt. Reach up to the dock and place your hands on it, using them to balance as you gently stand. Shift your weight to your hands as you stand, and sit on the dock.

2c

De aguas profundas

Entry:

This is by far the most difficult way to enter a kayak, and this method is really only used when recovering from a mistake. Swim alongside the kayak and pull your body, stomach down, on top of the kayak. Carefully sit up and grab the gunwhales. Swing your legs around and insert them into the cockpit. Bail as much water out as you can before refastening the sprayskirt.

Exit: If the kayak overturns while you are in it, do not panic. Remember that you can hold your breath for several seconds and that you are not about to drown. Calmly release the sprayskirt and push the kayak off your legs as if you were taking off a pair of pants. Swim to the surface.

If you find yourself in a situation where you think you should exit a perfectly good kayak in deep water on purpose, rethink your situation. You are almost never better off out of the boat. If you decide that you really do want to exit, release the sprayskirt. Place your hands on the cockpit rim and lift your bottom out of the boat. Sit on the rear deck and lift your knees out. Slip your legs into the water and swim.

Alternatively, you could just roll over and do the "wet exit" as described above, though this will cause the kayak to take on water, making it more difficult to re-enter.

Demostrar la capacidad para realizar las siguientes brazadas:

3a

Recto hacia adelante y hacia atrás con el remo

Grip the paddle tightly with your control hand (if you are right-handed, this is your right hand). Your other hand should hold the paddle loosely. To take a forward stroke, put the blade on the "control" end of the paddle in the water towards the bow. Pull the control hand towards your hip, push the other hand forward and twist the torso. The idea is to use the large muscles in the torso to power the stroke, not the arms. As you take the stroke, press the foot on your control side into the foot pegs and try to point your feet in the direction you want to the kayak to travel (in reality, which ever way your feet point is the direction you will travel). Draw the paddle to the stern and lift the blade out of the water. You are now ready to take a stroke on the other side of the boat. To do this, cock the wrist of the control hand as if you were accelerating on a motorcycle, and allow the paddle shaft twist in the other hand. Then plant the forward blade in the water and take another stroke, again, using the torso to power the paddle, and pressing the foot into the foot peg. To take a backwards stroke, reverse this process (except that pressing on the foot pegs will not really help).

3b

Remando de izquierda y derecha hacia adelante y hacia atrás

When you first learn to paddle a kayak, turning is easy - and often unintended. To make a turn to the left, take a wide stroke on the right (meaning the blade of the paddle will pass though the water at a distance from the boat), and take a close stroke on the left (meaning the blade of the paddle will pass close to the boat's hull). To turn right, reverse these two strokes.

For a quicker turn, take a wide forward stroke on one side and a wide backward stroke on the other. The kayak will turn in the direction of the backward stroke.

3c

Mover en brazada (amplia)

In this stroke, the paddle is planted in the water near the bow with the blade of the paddle parallel to the boat's center line (keel line). The paddle is then swept 180° in a wide arc to the stern, where it ends up parallel to the center line again. This is a turning stroke and can be done on either side, forward or reverse.

3d

Brazada de soporte

The support stroke is more commonly called a brace. This is done to steady the kayak or to prevent a flip.

To do a low brace, grip the paddle with both hands and raise the elbows. You can imagine that you are gripping the handle of a bicycle pump and getting ready to inflate a tire - the hold is roughly the same, except that the hands are farther apart. Then extend the paddle with the flat portion of the blade lying on the surface of the water and put some weight on it. If the water is moving, you can actually put all of your weight on the blade. The idea is to push down on the water, and it will push back on you, allowing you to right yourself.

A high brace is another support stroke, but executed improperly can lead to injury, usually a torn rotator cuff in the shoulder joint. To do a high brace on the right, cock the right wrist so that the paddle blade rests flat on the water. At the same time, bring the back of the left hand towards the forehead, put some weight on the blade and push off. Do not raise the left hand higher than the forehead, as this is an excellent way to tear your rotator cuff. It is better to just stick with the low brace, reserving the high brace for emergencies.

3e

Remando de cruzar la corriente

Cross current paddling is also called ferrying. This is a method of crossing a river (or a portion of a river). Point the bow of the kayak upstream, but angled slightly so that it points slightly toward the bank you wish to cross to. Then paddle forward against the current. The forward strokes should offset the backward motion caused by the current, but you should achieve motion to the side since the boat is angled. In swift current, you will have to work the paddle to keep the bow pointed in the right direction. The river may try to spin you around, and if it succeeds, you will flush downstream rather than ferry across the current. It's OK if you lose a little ground to the current, but be mindful of river conditions behind you. The idea is to move to the side.

Explicar los pasos que envuelven la vuelta esquimal y demostrar el buen método de hacerla.

Learning the Eskimo roll requires both instruction and practice. The roll itself is the act of uprighting an overturned kayak by use of the paddle and body motion. Typically by lifting the torso towards the surface, flicking the hips to right the kayak halfway up and applying a righting force by means of the paddle while tucking close to the front or back deck.

Several styles of Eskimo roll are in use including the "C-to-C", Sweep, Screw, and Extended Paddle (Pawlata). The roll styles in use vary both regionally and by type of kayak. In the USA, the C-to-C has traditionally been taught in the eastern half of the country while either the older screw or more modern sweep roll have been used in the western half.

The type of roll you should learn is the one that your instructor wants to teach you. It is nearly impossible to learn how to roll without an instructor, and there are few people who know more than a few types of rolls.

There are many kayaking clubs all over the USA and Canada, and they frequently run "rolling clinics" in indoor swimming pools during the winter months. Fees are usually low to cover the use of the pool, and club members often provide instruction for free.

Explicar cómo reparar un agujero en fibra de vidrio:

5a

De manera permanente en un taller (fibra de vidrio)

To permanently patch a hole in a kayak using fiberglass you will need the following:

• Fiberglass cloth, enough to cover the hole.
• Epoxy Resin
• Mixing container
• Paint brush
• Squeegee (Can be made from a plastic jug).

First, cut the fiberglass (regular scissors work fine) to an appropriate size to cover the hole. The patch should extend at least 2.5 cm beyond the edges of the hole. Cut another piece to cover the opposite side of the hole (you want to patch both the inside and the outside of the boat). Set the cloth aside and mix the epoxy. Do not whip air into the epoxy mixture. Lay one of the cloth pieces over the hole and apply the epoxy over it with the paint brush. Use the squeegee to press the epoxy into the weave of the cloth. Go over the cloth several times, but be careful to not move the cloth off the hole. Allow the epoxy to set, and repeat the procedure two more times. You will need three coats of epoxy to cover the hole. Once the outside has been patched, turn your attention to the inside, using the same technique. Finally, sand the patch inside an out, starting with 80 grit paper, proceeding to 100 grit, and ending with 220. Finish the patch with spar varnish.

5b

En una reparación de emergencia en la orilla del río (cinta adhesiva)

If possible, pull the boat to shore, dry the affected areas as best you can with whatever dry stuff you can come up with, and expose the hole to the sun so it will dry. Duct tape does not stick well to a wet hull, and the sun can dry a kayak surprisingly quickly on a hot day. When the area is dry, apply duct tape over the hole and press it down well - especially around the edges of the tape. Be sure to apply tape to both sides of the hole, that is, the inside of the boat as well as the outside. If you only patch the outside, when water slops into the boat, it will find its way to the underside of the outer duct tape, loosen it, and your patch will come undone.

Después de completar un mínimo de dos sesiones de entrenamiento, completar ya sea

a. Un viaje de la noche a la mañana en kayak

b. Dos días de viaje (uno de ellos debe incluir aguas rápidas)

See requirement 4 for links to kayaking clubs. Many of these offer training in the spring for a small fee. You can also check with local outfitters for commercial training programs or for information on local clubs. Clubs and outfitters will also be able to advise you on good rivers for an overnight trip or for a day trip including easy whitewater.

Where ever you decide to go for an overnight trip, you'll need to pack as if you were going on backpacking trip. Actually, you will be able to pack a little more than on a backpacking trip, because a kayak can hold more gear than a backpack, and you don't have to carry it full time (there may be portages though, so don't pack too much).

For a day trip, you should have everyone bring a sack lunch. This can be eaten on a calm section of a river or you can stop and eat on the river bank. You should also leave dry clothes for everyone in a car at the takeout.
