Thank you Peter!
In addition to the Windpilot's reputation for performance and reliability I can comment very favourably on the responsiveness of the company's owner, Peter Foerthmann. I reached out to him asking about vane dimensions, (to make a couple of spares) and any areas of wear or concern that I should be aware of, thinking that a 20-year old unit would require some service. He responded immediately with a .pdf copy of the manual, offers of help, and a request for photos of the unit to date it. These I sent, and he promptly determined that it is a current model. He then asked about the prior owners so he could determine exactly when it was installed. I provided this information, and again, a prompt response back confirmed the unit was purchased in 2019! He even sent photos of my unit installed and rigged on my boat. His comment on spare vanes:
Spare vane: the majority of sailors finishing their worldwide cruising / circumnavigations with one and the same vane …
like Golden Globe finisher 2018 Tapio Lehtinen: 322 days at sea with one and the same vane
