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

2b

Desde un muelle o desembarque

2c

De aguas profundas

Demostrar la capacidad para realizar las siguientes brazadas:

3a

Recto hacia adelante y hacia atrás con el remo

3b

Remando de izquierda y derecha hacia adelante y hacia atrás

3c

Mover en brazada (amplia)

3d

Brazada de soporte

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.
