5

Con la ayuda de otros, dar forma de manera correcta a la parte exterior de la canoa y hacer el hueco interior. Correctamente suavizar ambas superficies tanto dentro como afuera.

7

Ayudar en la elaboración de remos, asientos, postes y accesorios de la canoa.

Seats

The seats are made from wood which is shaped and fitted over the gunwales. They are shaped such that the bottom of the seat is lower than the gunwales. The seat will lift off the gunwales. When the canoe is dragged up onto the beach, the paddler will take both the paddle and the seat into his home.

Poles

The poles, like the paddles trade weight for strength. They are typically the same (or nearly the same) diameter from top to bottom. The length depends on the depth of the water in which they are used. Poles are used from a standing position, and the length reflects this.

Ayudar en la construcción de cubiertas, soportes adicionales, mástil y vela, si la canoa es de doble casco o de la clase de soportes adicionales.

Decking

Not all dugouts were outfitted with decks, but when present, decking is placed at both ends of the canoe to keep breaking waves from filling the boat. They help the boat to shed water. Decks are flat pieces of wood connected to the edges of the canoe and can be lashed in place by boring holes in both the hull (near the upper edge) and the deck. Once the deck has been lashed in place, the holes are sealed with pitch.

Outrigger

Outriggers of New Zealand consist of three parts: a pair of booms, connecting pegs, and a float. One boom is lashed to the canoe near the bow, and the other is lashed near the stern. Holes are bored into the hull directly below the booms so that cordage can be passed through them when lashing.

Each boom receives long pegs which are then connected to the float. The length of the pegs is adjusted so that the float will be positioned at the surface of the water. The pegs are lashed both to the booms and to the float. When lashing the pegs to the floats, a hole is bored through the float and the cordage is passed through it. This prevents the lashing from being positioned at the bottom of the float where it would be subjected to extreme wear and tear as the canoe is dragged across rocks and up onto beaches.

The float is typically pointed at the bow end and square at the stern.

Mast and Sail

If a canoe is outfitted with a mast and sail, it should also have outriggers. Otherwise, it can easily be toppled by the wind.

The mast is roughly 4 meters long and tapers from 28 mm at the top to 45 mm at the bottom. It is inserted into a hole in the seat, and then into a socket cut into the bottom of the boat to receive it.

Boom shoulders. The right side is the mast-end.

A few inches above the seat it is fastened to a boom. The boom is the same length and diameter as the mast. Shoulders are cut near both ends, with the mast-end having a deeper shoulder (see illustration).

The boom is simply tied to the mast, and the sail is tied to both the mast and the boom. The sail itself is triangular.

Hacer un modelo de árbol de la clase de canoa utilizada en su distrito.

Choose a soft wood and shape the model as closely as you can to match your canoe. People will often carve a scale model before beginning to shape the log. The model can then be used as a reference.
