FIELD: machine building.
SUBSTANCE: invention relates to water and land transport. Device for moving onto snow, ice and water surfaces, containing a traction and towing device, which is made as a catamaran containing a deck with floats, a deck superstructure and is made in the form of a catamaran able to move by means of easily removable ski-skates fixed on the floats – onto ice, snow and water surfaces. Distance (track) between the floats is made adjustable by the device. Contacting surfaces of the catamaran with snow, ice and water are made with a low coefficient of sliding friction, and the floats are made in the form of a light, strong, hermetic, tubular structure, the interior of which is filled with fragments of a light non-dipping material, for example, polyfoam.
EFFECT: increase in the efficiency of the device for moving onto snow, ice and water surfaces is achieved.
