WINDSURFING: the prize of “M-K” — “Orbit”

WINDSURFING: the prize of We can safely say: all-Union competitions “the prize of the Heroes of the Cosmos” today, the most popular competitions of fans of Windsurfing. Last year, no” was attended by about 170 athletes that were part of the 32 teams. Start hosted the Olympic “Windglider” and Board a free class. Won the master of sports of international class V. Overgrown” (Vodnik, the master of sports Yuri Kuznetsov (“Orbit”) and Janis SOPs (Republican Central yacht club, Riga); women — Y. Kazakov, I. Sklemina (both from the “Vodnik”) and the Leningrad M. Dubinko. Team championship the team of the Armed Forces.

“Our Board is better brand”, is proud to say many of the participants. In fact, the competition featured many of the original technical solution to the homemade shells.
Here is one of such innovations. Now enthusiasts of Windsurfing has developed new, more advanced manufacturing technology of the hull in vacuum. Design procnias it more evenly, without “bubbles” distributed source materials. Revealed the opportunity to leave the inner set of foam (60 dm3 according to the rules of construction) only for gain, and not to stack solid as earlier, leaves. The Board has become more light and resilient, to improve its driving performance, tougher now put the centerboard.
Learned craftsmen and “wound” fiberglass mast. It is especially well developed in Leningrad, engaged in the construction of the boards in the shipbuilding Institute, the enthusiasts section of the surfing society “Orbits of the suburban Kaliningrad.
It is the “Orbit” received the competition prize of our magazine. He was awarded the Turner to Alexander Sarychev. The fact that all the athletes are played on makeshift materiel: hull, masts, even the sails of their own manufacture. And ranked high. Using the “vacuum” method, they reduced the weight of the boards to a minimum of 18 kg, reducing their strength. The technology is somewhat harder than usual, experts say, but it turns out the Board with qualities better than the world famous company “Windglider”.
Surfing lately is much younger: at a national, very high-level competition almost one third of the athletes were under the age of 18. The young sixth — grader Serezha Vasiliev of the “Orbit”. Participated and entire youth teams. For example, the Minsk Spartak — entirely of eight – and ninth-graders, but those of the first adult level. Coach guys Anatoly Perepelkin says that they have in “Spartacus” surf begin to work with 4-6 grade. Go first on small sails — 3-3. 5 mA: get used to the Board, fix the proper stance, study management, “find” the wind. And then you get adult shells.
Board sailing free class
The Board of the free class (In — dimensioned width, control the width of the Central part of the Board between the K and M at a height of 22 mm; cross section a — a conditional within the boundaries of the K — M, VMP = 450).
While citizens race on Polish mostly buildings, but by the start of next year will be ready in a homemade “Monotypes”, which is going to build in their workshops.
After the competition we spoke with the senior coach of the Soviet Union in Windsurfing Yuri Shellakovym. He noted that in 1983 in the official races will be part of the Board “Monotype” (our national class) and a free class. The introduction of “free” boards due to the weak capabilities of the industry. So, “Windglider” produces under license in very limited quantities only Tallinn shipyard; “Monotypy” — the Lytkarino plant, shipyard Lazarevskoe, collective farm “Mayak”. In Feodosia continue to do composite “Mustangs”. In a word, the original is still open.
What is the Board free class? The housing can be made of plywood, wood, plastic, fiberglass. It must be at least 60 dm3 of the foam with closed pores to provide buoyancy. CFRP, titanium alloys, organic high-modulus fibers as the materials of construction of any element of the vessel is not permitted.
Maximum Board length of 3900 mm, and the fittings for the towing of the end of the 3920, measuring the width is not less than 630 mm, weight — 18 kg (with fin). The vertical distance between the measurement lines of the bottom and decks not exceeding 165 mm. Case should be of such strength that, when load 160 kg, uniformly distributed within ± 300 mm from the nest of the mast, it would not be afloat no deformation: General, local, residual. All protrusions on the deck for reasons of injury have to do with the radii of curvature of more than 15 mm. In the water under the Board with all its racing weapons should not remain any longitudinal air channel extending along the bottoms. Installing the foot straps is prohibited.
The centerboard surfer required buoyancy, it is forbidden to operate it at a distance: using lines, tips, etc. to Insert it you need ferchu, and to be below the measurement line of the bottom it may be more than 700 mm. it is also Prohibited to have three or more of the fins; if they are two, they are located at the same distance from the transom, but no further than 700 mm from it. Fin must not protrude above the deck or go more than 300 mm in depth.
On the mast there are fewer constraints imposed, the Builder here more freedom in the choice and design geek, the way of attaching it to the mast and the sail at all arbitrary. However, the height of the mast from the surface of the boards should not exceed 4700 mm. it is also Necessary that in any cross-section it was round, with a constant along this section, with the thickness of the walls: bending it should be the same in any longitudinal plane. Permanently curved masts are prohibited, but allowed for some narrowing them to the extremities. Top and NOK are closed by plugs to prevent ingress of water inside afloat.
The main dimensions of the sail

Hinge shall operate under the influence of a sharp leap upwards, freeing the mast, and allow it to tilt freely in any direction at an angle of 90° from the vertical. At the same time, its design, and ferrules for wire luff point, is arbitrary. Adjustment of the bend of the mast can be carried out only with the help of the backstay sheet and angle of boom, and line for lifting masts; all sensible things that are essential for control rigging, stoppers, blocks, etc. — should be attached to the mast or boom.
The sail is sewn from non-woven material, Mylar, or anything similar are not permitted, but the window — one or more — made from any, only their size is limited to 0.4—0.8 m2; they are located no closer than 150 mm from any edge of foot. The flag is triangular, is placed on the mast sleeve width 150 mm and length of 440 mm in an arc from the head points to the tack corner. Ladermann no more than three; only put on the back foot. Their length 375, 525 and 275 mm, counting from top to bottom, width 40 mm, they should be placed no further than 100 mm from the measuring points. Gain — boty increasing rigidity of the sail is permitted only within 400 mm from the corner. Patch palovich and Skitovich boards is not permitted. Grommets are placed one by one in the corners. But for slab, you can sew another one on the back foot.
Amateur builders also need to remember that each Board is on the left outer side of the transom should bear the registration number assigned national sailing Federation. There are issued and numbers on sails improvised. They are nailed over the window, below the emblem of the class. Their sizes: height 250 mm, width — 165, the thickness of the lines 35, the distance between the marks is 60 mm.
