Greetings and welcome aboard the CF, Sven.

I think that the CYS system was described by Dan Spurr in “Upgrading The Cruising Sailboat”*.

Welcome.

Where did you find the picture? That might help us find some info...

Hi,
some years ago I asked about that windvane recently I found it in:
"Spurr's Boatbook, Upgrading the cruising sailboat", 2nd edition, page 139 .
On page 141 Spurr writes, that "Bob Verhaeghe" was the builder of that CYS vane. Unfortunately I found nothing about him in the Internet, does perhaps anybody know or have heard about him ?

Looks like an Adams?

If you mean Adam Windpilot as shown in the photo, no it isn't.

Why are you asking?

If you are trying to reverse engineer or come up with a similar design i may have a source of drawings. John Belcher drew a few, I have one.

Page 48 of Peter Forthmann's book "self-steering under sail," downloadable here,

WINDPILOT: selfsteering under sail

has one of the few references I've ever seen to vertical shaft trim-tab-on-auxiliary-rudder systems.

I do my best googling when I know the reason for the search though...

ps Rodger Martin seems to be a yacht designer from SA, didn't look any further.

Just ran across the post--and a very late reply:

I have the CYS wind vane on my Pearson 30.

Cheers!
