Snow raft having a plurality of adjustable speed control studs

1. A snow raft for use on snowy inclined terrain consisting of a shape that is longer than it is wider and having one end that is generally triangular in shape and an opposite end that is generally flat in shape; the shape being generated by way of rotomoulding process so as to create a monohull structure composed of five conjoined continuous generally cylindrical elements joined at both extremities by a generally flat member which defines the opposite end; the five generally cylindrical elements define an interior space having a bottom; the interior space as at least three built-in seats; each built-in seat has a horizontal seating portion and a perpendicularly extending vertical backrest extending integrally from the seating portion of each built-in seat and wherein the last built-in seat has the flat member also forming the backrest extending integrally from the last built-in seat; the underside of the raft has a rudder to prevent sideways sliding; the underside of the raft further comprises a plurality of retractable studs that are adjustable and interchangeable by way of threading and unthreading so as to control the speed of the raft by varying the friction coefficient.
