WindPilot Pacific Self Steering Wind Vane w/ Spares. Taken off of my 32 foot sailboat in perfect working condition.
The WindPilot is lighter and (IMHO) MUCH easier to install than a Monitor. 

Comes with the standard MF 0 mounting brackets and 2 sets of MF 1 brackets 
2 vane blades
2 crossbars 
Misc. spares and mounting hardware.

Shipping quote is just an estimate. I will have the vane professionally boxed and shipped from Fedex ground.

Pickup preferred in the San Francisco Bay Area. 

Feel free to ask any and all questions.

Thanks for looking and GOOD LUCK!
