A multi-view video camera system (25) for filming a windsurfing sailor during sailing, comprising of two video cameras in waterproof compartments (7) with lenses (8) and screw caps (29) attached to a clamp (10) with tightening screw (9) and wing nut (23) for attachment to the mast (11) of a windsurfing sail rig (22). The compartments (7) are oriented to aim the contained video cameras (24) along each side of the windsurfing sail rig (22) at corresponding locations a windsurfing sailor would occupy while sailing the windsurfing sail rig. Video streams, resulting from the contained video cameras could then be combined into single composite video for analysis.
