ABSTRACT:
A wind direction device for attachment to a boat shroud for indicating the direction of the wind relative to the direction of travel of the boat. The device includes several wraps of adhesive tape around a boat shroud to form an upwardly facing shoulder at a mid-point of the shroud of the boat, a bearing resting on the shoulder and having a hole through which is received the shroud, which bearing has a slit in one side and is sufficiently flexible and resilient so that the size of the slit can be varied to position the bearing around the shroud and retain the bearing on said shroud, a tubular mandrel resting on the bearing and having a bore through which the shroud is received, the mandrel having a slit traversing the length of the mandrel, the mandrel being of sufficient flexibility and resilience such that the size of the slit can be varied to position the mandrel around the shroud and retain the mandrel on the shroud, and a resilient vane connected to the periphery of the mandrel.
