windsurfing

Windsurfing is a surface water sport using a windsurf board, also commonly called a sailboard, usually two to five meters long and powered by a single sail. The rig is connected to the board by a free-rotating flexible joint called the Universal Joint (U-Joint).

A windsurfer holds the world speed record for sailing craft; and, windsurfers can perform jumps, inverted loops, spinning maneuvers, and other "freestyle" moves that cannot be matched by any sailboat


Modern windsurfing boards can be classified into these categories:


Freeride:

Boards meant for comfortable recreational cruising at planing speed, mainly in flat waters or in light to moderate swell. The so-called freeride sailing movement diverged from course racing as more recreational sailors chose to sail freely without being constrained to sailing on courses around buoys.

Formula Windsurfing Class:

Shorter boards up to one meter in width, for use in Formula Windsurfing races.

Wave boards:

Smaller, lighter, more maneuverable boards for use in breaking waves. Characteristically, sailors on wave boards perform high jumps while sailing against waves, and they ride the face of a wave performing narrow linked turns. The most common sizes of sails used with wave boards are in the range of 4.0 to 6.0 square meters, depending on the wind speed and the weight of the sailor.

Freestyle boards:

Related to wave boards in terms of maneuverability, these are wider, higher volume boards geared specifically at performing acrobatic tricks with widths frequently in excess of 60 centimeters. Freestyle boards began to diverge more noticeably in design from wave boards in the early part of the 2000 decade, as aerial tricks became the predominant part of the freestyle repertoire, superseding Old School moves, in which the board did not leave contact with the water. These boards also incorporate a fairly large amount of fore and aft rocker to make leaving the water (jumping) easier.

Slalom boards:

Shortboards aimed at top speed, rather than maneuverability or ease of use.

Beginner boards:

these often have a daggerboard, are almost as wide as Formula boards, and have plenty of
volume, hence stability.

Racing longboards:

Mistral One Design, or the Olympic RS:X class race boards.

snowboard

The snowboard is the joungest subject of the F.I.S., it makes a mixture of classics elements inhered of the Alpina's competition


Several types exist of snowboard:


Two runners compete at the same time, for ot one gate route.

Giant Parallel Slalom:

The giant parallel slalom it's the same than the normal parallel slalom, but it's less doser than that

Halfpipe

the participatings carriying in a jumps group, acrobatics and maneuver in the halfpipe, going from side to side rising for the edges of the pipe

Big-Air

It is a " big jump " that is judged according to the criteria: control of the acrobatics, extent, and landing

Acro-Snow

The corridors do the joint exit in groups of four in a sinuous track specially constructed for the snowboard that includes returns, jumps, waves and the equipped snow
