<p>The mast footing (3) is fixed on a ski (1), so that the ski can be used with a sail for sail skiing. The footing is fixed on an aluminium plate (2) screwed on the ski in front of its fixings (5). In the centre is a hole (4) in which any type of sail board mast can be fitted. It can be fixed to a normal alpine ski or to a mono-ski, when it fits between the two front stops of the fixing.</p> |
