You have most of your statements correct. However, the pennant on the cockpit is both, a back up to be able to raise the board if the main line breaks but more than that, this line was designed to make the board travel stop at the correct angle that you mention. The angle where to "set" the board by adjusting the pennant is, as you mentioned, approximately 45 degrees. The way to adjust at the angle is to let the board down to the point where the "shoulder" built-in on the board is flush, or parallel to the bottom edge of the keel. Letting the board down all the way may change several parameters of proper balance, namely… center of resistance displacement, increase weather-helm, etc.
The wedges do work, as we know from people who have done this. My preferred version is to glue them (Plexus) and through bolt them on the low, or leading edge of the board. The increase resistance will be less than the benefits. These wedges can be made with "Starboard" material. Thanks

Any change in the designed shape of the board will result in more drag and less lift which means anything attached to it will diminish its purpose.

PS Tony Pocklington is currently making me a new board and his father Joe will install it -under my intense scrutiny...board cost is $4500.

That is… if you sail your Brewer as you sail a 12 meter at an old America's cup race. If, on the contrary, you sail your Brewer as we all sail our cruising boats (with a barnacle here and there) you will never notice that diminish geoleo is talking about, which is try of course but a matter of degree.

HI William,

I have a Brewer 12.8 and the center board pennant needs replacing.

What is the procedure you used?

Any pictures?

Bruce
