ABSTRACT:
The invention provides an apparatus for resiliently securing a pair of skis together in generally parallel relationship, and for receiving a sail rig as commonly used on a conventional sailboard, to permit conventional snow skis to be used in a manner similar to a sailboard. The apparatus comprises a cross piece to extend transversely between the skis, with a central portion of the cross piece connected to the sail assembly. Ski connectors connect each ski to respective opposite end portions of the cross piece. Each ski connector has at least one resilient flexible link, and at least one pair of anchors for anchoring the flexible link to respective end portions of the cross piece, and for preventing gross movement of the flexible link as a whole. The link extends between the anchors and is engageable with a projection on the ski. The link passes around the projection to draw the projection resiliently against the respective end portion of the cross piece. Resilience in the connection permits limited rotation of the ski relative to the cross piece about a longitudinal ski axis of each ski, and about a yaw axis of each ski disposed perpendicularly to a base of the respective ski. The projection can be a support releasably attachable to the ski at a selection of locations, or a specific type of conventional ski binding toe piece.
