Yes I have one installed on my 33ft yacht. Works brilliantly. I am in
Australia and it cost a lot to ship but still came out cheaper than other options. I am very pleased with my
purchase decision. Product very well made.
I have got to know the developer of this product quite well through this
purchase. He hasn’t made it publicly advertised as yet but has
sold many and lots of big yachts using the Provane successfully for ocean passages.
You can access his site which sells another wind-vane called the Windy, at
https://windyselfsteering.com/selfsteering/
Use the contact page on the site and tell him Mark from
Australia referred you.
Good luck.
