“SKI SAILING”

In recent years, numerous sailing sports have added one: winter Windsurfing. At first, he spun off from the classic surfing as a way of year-round training: created a kind of simulator, which, according to enthusiasts, was to stay in shape during the “closed” waters, and also serve to teach beginners the basics of the art control boards. However, the training was so fascinating that soon had the idea to conduct a trial competition “sailing skiers”.

It’s gone. The people of Leningrad, for example, organize a city championship on winter Windsurfing on ice of Gulf of Finland. Used with the competition Rules of sailing boards, of course, with some additions reflecting the specific races. So, you are allowed to make no more than two steps for acceleration at the start, after the fall, as well as full stop in the wind. In such cases it is possible to push it with your foot like a scooter, not letting go, however, from the hands of a geek. You could step a couple of times and braking distance (from a rotary sign to avoid collision, etc.).
The distance is marked triangular in plan with sides equal to approximately three kilometers. Regulations 5 to 7 races.
 
WINTER SURFER MONALIZA
 
For the manufacture of ski surfer requires matched in the growth of the slalom or ski jumping (preferably plastic) and equipped with a sail and a mast. On the ski on the three pillars is a reference platform-a deck made of plywood, metal or plastic Stasova box mast is placed at the center of gravity, its depth must correspond to the dimensions of the pivot joint. At the beginning of the deck is attached a rubber or a wooden fence, and along it the entire length — rubber strips.

1 right ski 2 — rear Forte, 3 — rear strut, 4 — strut bolt. 5 — screw-lock, 6 — hole deck bolt M6, 7 — liner-socks 8 — tight ski mount.

 
The three front platform height about 60 mm represent dural P – or L-profiles with frame, wall thickness of 2-3 mm. and their combination with the ski on the screws, with a platform — bolt-on M6.
 
Skates — two on each “side” is made from strips of stainless steel with a height of 20-25, with a length of 200 and a thickness of 2-3 mm. they resemble the shape of ice-yacht skates with Shoe, only fastened simpler: a few screws, screwed from the side in the ski. They sharpen from the outer side at an angle of 60 , with interior to 30°, the height of sharpening of about 3 mm. just so they stand under the lower gliding surface of the ski.
 
Practice shows that skating is not always necessary. For example, on soft, fresh snow to ride without them.
 
PLEASURE COMPROMISE
 
Now imagine just for a minute such picture (the one who had to deal with the wind to draw it yourself is not difficult): what happened, for example, to go far away sailing on the ski.
At this time the wind began to subside, disappeared altogether. Waiting him new impulses were vain. And you back knee deep in snow, pull a ski and sail. And easily slide past the “normal” skiers. At such moments especially want to have some kind of “compromise”, and sailing like it was possible in a calm home. This is the walking version of a winter surfer on two skis. You will need to him a couple of regular cross-country skis with rigid mounts. The remaining part — improvised deck, stand, skates, together with the surfer spars — mast, boom-wishbone and the sail area of 5.2 m2.
 
Deck size 300X1000 mm can be plywood, but better to take her duralumin sheet thickness of 3 mm — this will give a gain in weight, and the top to stick a rubber corrugated Mat. Stands or blocks of wood or L-shaped metal profiles that are installed across the ski two: the cargo area and the back. Mount to the deck with M6 bolts with countersunk heads. Bottom racks the same bolts fasten the skates: corners, stainless steel 40X40X3 mm. They are designed for driving on ice and snow: you can use aluminum of the same size. So, Holly, stands and skates make up a single structure, which during Assembly of the surfer is entirely on skis.

1 — the second section, 2 — bolt-lamb 3 — nut-lamb 4 — strip-rod 5 — screw attachment, 6 — first section.

 
This front rack is equipped with a semicircular metal inserts their holes they are like socks ski boots are placed on the spikes of the fasteners. Rear front racks have a special slot, which is included under the head of the lock-screw, screwed into the ski. As you can see, everything is simple, so the time of Assembly and disassembly of the housing less than a minute.
 
A few more have to bother with a mast and a boom. The first is its length of about 4,300 mm — assembled from two parts, and wishbon (2700 mm) — of the four. Connection for bushings with fixing bolts.
 
If you have to go skiing, then part of the mast fit into the case which is tied between the uprights of the deck. The racks pass through the shoulder straps.
 
Just as the windsurfers, you can create a double “ice” ski: a tandem with two hulls, masts, sails. They are connected in line, what to deck the front of them screwed two metal strips (20Х200Х4 mm), the ends of which hang down to 60-80 mm. they drilled the holes for the M6 bolts with nuts horses, and return are on skis socks the second section, that is, the mount is sufficiently tough. It is controlled by the tandem, of course, the two of us.
