ABSTRACT:
The present invention relates to a board 1 suitable for use in descending a snow slope. The board 1 has a generally flat elongate base 15, a forward portion 2 with an upturned leading edge portion 12, a user support portion 4 and a rearward portion 3 comprising at least partly independently movable left and right support portions 18, 19 extending generally alongside each other rearwardly from said forward portion 2.
The base 15 has outer side edges 7, 8 of generally angular cross-sectional shape for biting into the surface of a snow slope during turning in use of the board 1. The side edges are furthermore concavely arcuate, in plan view, so that the board 1 is substantially waisted intermediate its ends 12 and 14 so that the board can proceed along an arcuate path when one of its side edges 8 is weighted and the other 7 unweighted.
