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.
Fig. 3. Walking tandem.
Fig. 4. The connection sections of the tandem:
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.
