SAIL RISES ON SKATES

SAIL GETS ON SKATESIs the bright spring sun to drive away the snow from the ice shell, takowego rivers, reservoirs and lakes, as on natural ice tracks immediately appear multi-colored sails. This glider.
Each of the readers may become Barista to make the ice yacht can anyone who has plumbing and joiner’s skills.
 
In the development of the glider adopted a scheme the most common device class “DN” with the front steering skate, an open cockpit and cockpit controls. Sail — sailing Board. For small sailboats, which is Buer, it is the most simple and effective. This decision will significantly simplify the construction of ice yachts of Amateur designers: after all, the biggest hassle in the construction of sailing sailing gives the purchase of fabric and sewing of the sails.
 
The Buer of this type has a good performance: when the wind is 4-5 m/s on smooth ice, its speed reaches 40 km/h. It is well managed and quite safe. Track glider, which provides good stability even in strong winds, is 2,500 mm, which ensures from tipping over. The cross beam can SAG, damping under loads.
It is best to use a sailing rig from the Board type Akvata, although in principle suitable sail and any other type. In addition, this allows the sail to adapt the same Buer in the ice windsurfer.
 
The case of Buer — collapsible, tubular, and the length of any part does not exceed 2,200 mm, allowing you to carry it disassembled even by public transport.
 
Collapsible Buer class 6 m2.
Collapsible Buer class 6 m2:
1 — the sail with the mast (sailing boards Akvata or other type), 2 — skating with the clutch mounts to the joists, 3 — cross-beam, 4 — hull yachts (cockpit), 5 — a longitudinal beam (jib-boom), 6 — steering gear.
 
The base of the body of the glider is made of duralumin tubes of the cockpit, on the fence which is stretched a thick nylon net or a tent made of durable and lightweight canvas. Longitudinal beam-jib-boom is designed to increase the structural length of the Buer. It is fixed in the front of the housing tubular clamp with bolt M8. On the jib-boom mounted steering — it consists of coupling the front of the horse with shaft and lever and traction. The lever with the rudder tiller attached to the enclosure base. For ease of Assembly and debugging of the steering device structure is provided adjustable along the length of the tubular rod.
 
The main nodes of Buer.
The main nodes of Buer:
1 — the sail with the mast, 2 — forestay (steel wire rope Ø 3 mm), 3 — clutch fastening skates to the joists (3 PCs.), 4 — skates (steering and support), 5 — steps, 6 — longitudinal beam (the dural tube Ø 40X1,5 mm), 7 — adjustable tie rod, 8 Parking brake, 9 — tiller, 10 — hull yachts (cockpit), 11 — tent (mesh) cockpit 12 — enclosure of the cockpit, 13, 14 — cross beam (dural tube Ø 40X1,5 mm), 15 — the guy (steel wire rope Ø 3 mm) 16 — boom-mainsheet, 17 — wiring blocks ghica-sheet, 18 — unit with the stopper.
 
Sail with the mast.
Sail with mast:
1 — mast (dural tube Ø 40Х1,5 mm) 2 — gik (dural tube Ø 30Х1,5 mm), 3 — sail 4 — through battens, plastic, 5 — Shkotovo brace, 6 — gallova brace, 7 — the sheet for attaching the boom to the mast, 8 — clip for attaching the forestay and the guys to the mast.
 
Hull yachts (cockpit).
The body of the glider (the cockpit):
1 — cheek (duralumin with a thickness of 5 mm), 2 — sleeve (dural tube Ø 22X3 mm), 3 — base (dural tube Ø 45X2 mm), 4 — fencing (dural tube Ø 22X2 mm), 5 — stand (duralumin tube Ø 22X2 mm), 6 — crossbar (dural tube Ø 45X2 mm), 7 — clincher (aluminum 5X10X50 mm).
On the longitudinal beam is installed and fixed by M8 screws adjustable T-shaped mast steps made from cut cut along the dural tube and welded to it retaining cheeks that are used to pivotally mount a cylindrical Cup in which the mast is fixed.
 
When setting up the sailing of the armament of the steps can be moved along the longitudinal beam of the hull of the glider and fixed in the optimum position locking bolt. In addition, the mast, together with a glass of the steps can be tilted in the longitudinal plane glider — it also gives the possibility of additional adjustment.
 
Cross beam mounted in the rear part of the body of the glider. They are quite elastic and can bend, playing the role of shock absorbers.
 
And depending on the state of the ice cover on the Buer can be set special skates of various types.
 
Sailing rig — sail, mast and boom use from sailing boards of any type. The preferred method is from the “Equity” having an aerodynamically efficient sail made of modern materials with a through armor. The mast, in the upper third from the top, install the fittings for fastening the forestay and vant, and in the pocket of the sail is the corresponding window.
 
The fittings for attaching the forestay and the guys to the mast to perform better moving. Then adjust the tension of the standing rigging can change the position of the ferrules with the wire passing through the top of the mast.
 
When setting up sailing arms movable steps of the mast allows you to adjust its position and tilt, thereby changing the alignment of the Buer.
 
To secure the mast, use the forestay and shrouds from steel cable Ø 2,8—3,2 mm. To adjust the length of vant and the forestay you can use an ordinary turnbuckle.
 
For posting boom-mainsheet uses four blocks. One (with stopper) is fixed on the tiller head, the second is on boom at Shkotovo angle of the sail, and the third on the mast at the tack corner of the sail, the fourth — on the basis of an awning of the cockpit behind the steering.
 
All three of the skate design is the same, they are cut from sheet steel with a thickness of 5-6 mm, equipped with dural plates. The steering ridge further plate mounted Parking brake. The skates are mounted on the beams with no suspension springs as beams provide sufficient attenuation of the cockpit steering. When assembling it is necessary to provide parallel skates.
 
In our Buer with a front steering skate remote: structurally, it is somewhat more complicated direct, but it is much easier for the driver.
 
Diagram of the steering gear.
The schema of the steering gear:
1 — tie a horse 2 — track rod 3 — tiller to 4 — tiller rudder, 5 — levers of the turntable.
 
Clamp skates.
Clamp skates:
1 — the clamp (dural tube Ø 45X2 mm), 2 — cheek (duralumin 5 mm thick), 3 — solitaire (duralumin 5 mm thick), 4 — bushing (dural tube Ø 22X2 mm).

The rudder tiller.
The rudder tiller:
1 — shaft (steel rod Ø 15 mm), 2 — lever swivel device (steel 4Х35Х110).
 
Fad.
Skate:
1 — the blade (steel 5X80X500 mm), 2 — the brake hinge pin (bolt M6), 3 — nut, 4 — pin brake (steel 5X20X100 mm), 5 — plate (aluminum 10X35X300 mm), 6 — pin, 7 — washer 8 — bolt М8Х40 mm, 9 — nut, 10 — fork (welded from steel “corners” 40X40X4 mm), 11 — the lever of the rotary device (steel 4X35X110 mm).
 
Rumple.
Rumple:
1 — clip (steel 10Х20Х135 mm), 2 — hinge (M6 bolt), 3 — nut, 4 — arm tiller (oak or beech 15X20X500 mm), 5 — Central handle (oak or beech Ø 40 mm) 6 — weight (duralumin 10X20X180 mm), 7 — screws Ø 5 mm 8 insert (oak or beech).
 
Tie rod.
Tie rod:
1 — thrust (dural tube Ø 22Х2 mm) 2 — ear (aluminum 3 mm), 3 bolt M6 4 — nut, 5 — dural pipe telescopic rod (tube Ø 26X1,5 mm).
 
Fork the steering of the skate.
Fork the steering of the skate:
1 — shaft (steel rod Ø 15 mm), 2 — steering arm (steel 4Х35Х110 mm), 3 — a plug (made from “parts” 40X40X4 mm).

 
As we have said, all versions have a Parking brake, which is a steel plate that is installed on the steering ridge. On the go plate is raised, and the Parking lot on the end of her falls on the ice until it stops. Berestov there is a rule — regardless of the length of the Parking lot to put the Buer on the brake rastrelivat boom-sheet, and in a strong wind also let down the sail. On the move the driver brakes with his foot.
 
Design yachts designed with the possibility of quick Assembly and disassembly (25-30 minutes) and easy transportation.
Weight of fully equipped yachts not exceeding 25 kg. All the parts of a sailboat can be Packed in two bags: bag size 1400X500X300 mm (the bottom of the housing, the skates, the sail, ropes, steering) and pencil case size 2200X600X200 mm (gik, collapsible mast, the longitudinal and lateral beams of the housing, fasteners).
 
I would like to warn that the training of Berestov can be dangerous if not follow a few simple rules. When cornering at high speed or in cases where the driver loses control of the Buer can fall over. To avoid possible injuries in this case, the driver should be dressed in soft, warm, but not constraining movements clothes to have on hand in mittens or gloves. The head definitely need to wear a helmet or hat with earflaps. You are not close to places of a congestion of people (e.g. fishermen, sitting at the hole), to draw near to polynyas, areas of thin ice or any obstacles.
 
To prevent tipping in strong winds posting boom-mainsheet to allow the unimpeded movement in the blocks.
