Competitions

Slalom at the 2005 national championship at the Columbia River Gorge.In windsurfing competitions, there are the following disciplines:

Olympic Windsurfing Class
Formula Windsurfing Class
Slalom
Super X
Speed Racing
Freestyle
Wave
Freestyle and Wave are judged competitions, the sailor with best technique and diversity wins. Olympic Boardsailing, Formula windsurfing, Slalom and SuperX are races where many sailors compete on a course, and Speed Racing is a race where sailors compete on a straight 500 m course in turns.


*Olympic class
In Olympic Windsurfing 'One Design' boards are used. All sailors use the same boards, daggerboards, fins and sails. The equipment is chosen to allow racing in a wide range of sailing conditions. This is important for the Olympic Games, as events have to take place regardless of whether there is enough wind for planing.

The Neil Pryde RS:X is the current olympic class which is going to be used for the first time in the 2008 Summer Olympics.


*Formula class

Formula racer in San Francisco Bay.Formula windsurfing has developed over the last 15 years in order to facilitate high performance competition in light and moderate winds. Formula is now a class of windsurfing boards controlled by the International Sailing Federation that have the principal characteristic of a maximum 1m width. They have a single fin, with a maximum length of 70cm and carry sails up to 12.5 m2. Class rules allow sailors to choose boards of different designs, as long as they are certified as Formula boards, and use fins and sails of different sizes.

Large sails in combination with the 'wide-style' design allow planing in very low wind conditions. However, if these requirements are not met, the boards cannot be used and events will not take place, as non-planing sailing is very difficult with this design. Formula boards are used on "flat water" as opposed to coastal surf; but racing is still held in windy conditions involving swell and chop.

Formula boards have excellent upwind and downwind ability, but are not very comfortable on a beam reach unless sail and fin size are reduced. This explains why the course is usually a box with longer upwind and downwind legs, or just a simple upwind-downwind loop.

International Race Calendar Formula Windsurfing including results, equipment list, reports, photos and videos

*Slalom
Slalom is a high speed race in a course shaped like a figure of eight. Most of the course goes on a beam reach with floating marks that have to be jibed around. Slalom boards are small and narrow, and require high winds. Funboard class racing rules require the wind of 9-35 knots for the slalom event to take place.

International Event Calendar Slalom Racing with results, reports, photos and videos

*Super X
This is a new discipline in windsurfing competitions, a cross between freestyle and slalom. The competing sailors are racing on a short downwind slalom course, have to use duck jibes on all turns, and are required to perform several tricks along the way, such as jump over an obstacle, body drag or even front loop. The competitors are required to wear protective equipment.


*Speed sailing
Speed sailing takes several forms. The ISA (International Speedsurfing Association) organizes ( under the umbrella of the ISAF) competitions in various locations around the world known for conditions suitable for good speeds. The events are made up of heats sailed on a 500m course. The average of each sailors best 2 speeds on the 500m course which is typically open for 2 hrs/heat is their speed for that heat. As such it is possible for the sailor with the outright fastest time not to win the heat if his second best time pulls his average down. Points are given for the placings in the heats and overall event winner is the sailor with the best point score (again not necessarily the fastest sailor). Likewise points are given for places in the events and at the last event a World Speedsurfing Champion is crowned.

On record attempts controlled by the World Speed Sailing Record Council (WSSRC) competitors complete timed runs on a 500m or 1 nautical mile (1,852m) course. It is not a competition as such but a race against the clock. The current outright (500m course) sailing record is held by Finnian Maynard at 48.7 Knots. Finian also held the nautical mile record which he took from Bjorn Dunkerbeck at Walvis Bay in Namibia in October 2005 in an epic contest with Dunkerbeck and another multiple world windsurfing champion Antoine Albeau. In October 2006 Dunkerbeck improved on Finian's speed of the previous year by over 1 knot. Currently his best nautical mile speed is 41.14 knots. A new record can not be publicly claimed untill verified by the WSSRC who has an observer at the event.

With the advent of cheap and small GPS units sailors have been able to organise impromptu competitions amongst themselves as well as more formal competions such as the European Speed Meetings and Speedweeks/fortnights in Australia. See www.gps-speedsurfing.com for more information. With over 1200 sailors registered it is possible for windsurfers all over the world to compare speeds. Late October/early November 2006 was a particularly good time for fast speeds. In Namibia, Hennie Bedenkamp was the first sailor over 40 knots for the nautical mile on Oct 31 2006. Later that day Dunkerbeck did improved this to 41.14knots. The next day in Holland, Martin van Meurs achieved a peak gps speed of 46.9 knots.On 11 November Bob Cunningham achieved a peak of 45.2 knots at West Kirby in the UK while in the southern Hemi-sphere Chris Torkler made 44.6knots in Auckland , New Zealand on the 9th and Chris Lockwood achieved 48 knots at Sandy Point in Australia on the 13th November 2006.


*Freestyle
Freestyle is a timed event which is judged. The competitor who has the greatest repertoire, or manages to complete most stunts, wins. Freestyle is about show and competitors are judged on their creativity. Both the difficulty and the number of tricks make up the final score. Sailors who perform tricks on both tacks (port and starboard) score higher marks. High scoring moves include; Double Forward Loops, the Funnell (invented by freestyle champion Ricardo Campello in memory of Andy Funnell), the Chachoo and the Clew First Puneta (switch stance Spock)

*Wave

Wave sailing at Ho'okipa Beach Park, North Shore Maui, a location for many international wave competitions.Similar to freestyle (though wavesailing preceded freestyle) except that the stunts are generally performed in surf and points are awarded for how well the waves are ridden. A typical wave contest will score two jumps and two waves. A good heat would consist of a clean forward rotating jump, a backward rotating jump, a long slashy wave ride and a trick on the face of the waves such as a goiter or wave 360.

*International stars
Robby Naish: one of the first windsurfing champions to gain long-lasting international fame, he dominated the early years of competition in the 1970's and 1980's. Pre-PWA World Champion from 1976 to 1979, PWA Overall World Champion from 1983 to 1987, and PWA Wave World Champion in 1988, 1989, and 1991.
Bjorn Dunkerbeck: the successor to Naish, he dominated competition for many years in the late 1980's and 1990's. Twelve time PWA Overall World Champion.
Ricardo Campello: a freestyle innovator, he created many new difficult moves, PWA Freestyle World Champion in 2003, 2004, and 2005.
Gal Friedman
Kauli Seadi: Pioneered freestyle maneuvers in wave competition. Ranked first in PWA Wave competition in 2005.
Allison Shreeve Ranked world number 1 in Women's Formula Windsurfing.
Karin Jaggi
Natalie Lelievre
Daida and Iballa Moreno
Jason Polakow
Kevin Pritchard

*Youth windsurfing
Anyone above the age of 3 can start windsurfing with lightweight sails and boards. People from the age of 8-15 can become involved in t-15 windsurfing and can get together with other clubs and race for prizes. There is also freeride sailing where youth sailers can just have fun. There is also the Techno 293 (T293) class for juniors (under 15) competing on a 6.8m sail and youths (under 17) competing on a 7.8m sail. Both classes compete on the Bic Techno 293 (205l volume) . They compete in winds from 5 - 25knts. The current world champion is Ali Masters from Bristol, UK.
