The O-vane by C-vane is the masthead wind indicator sure to point in the right direction. Why is the O-vane so great? Well the arrow is permanently attached so you'll never lose it; it is also a perfectly balanced indicator with the lowest friction of any indicator in its class. The O-vane easily slips in the top of the mast with a 4mm needle construction.
It is available in the four different colours of black, neon yellow, bright orange and hot pink.
The O-vane is developed with the optimist in mind but can also be used as a masthead indicator for other classes including the Laser, and O'pen Bic.
