Windex 10 is a wind indicator with a 10 inch vane, designed to show wind direction on smaller sailboats and dinghies. Knowing wind direction allows sailors to make sail adjustments underway. Windex assembly includes 10 inch vane on a sapphire suspension bearing, held by a rod and glass re-inforced polycarbonate J-base. J-base is capable of mounting on side, front or top of the mast.

Adjustable tacking arms with tabs are a useful reference to pointing ability to windward. Both the tabs and vane incorporate reflectors for optimum visibility day and night.

Spare replacement vane for the Windex 10 is also available.
