During any given regatta, one sailor will cross close enough to windward of another so that their boom passes just above the wind indicator of the leeward boat. Any Laser® sailor knows what happens next. The mainsheet eventually rips the vane from its bracket, never to be seen again.
There is a better way. C-VANE is here.
When a threatening mainsheet passes over a C-VANE, it merely slides down the bracket, making a casual spin of the vane without hanging up. Away it goes, leaving the wind indicator still attached and fully functional.
Full protection from accidental removal and designed with less friction than any other small boat wind indicator, the C-VANE is the new paradigm for single handed sailors of all designs.
