The pointers are not useless on the rotating mast if you think about it.
Instead of spreading them to show the normal 45 degrees on a fixed mast, try this out.
Bend them in closer to have a total spread of 20 degrees, with each one being 10 degrees from the centerline.
(Not the 45 degrees from centerline you'd normally expect).
Mine almost touch each other set at 20 degrees.
The mast rotates about 55 degrees from the centerline, and there lies the trick.
That means the "windward" indicator will now be at 45 degrees to the centerline and the "lee" indicator is at 65 degrees to the centerline
after the mast has rotated.
The space between the two is the mast angle of 55 degrees, usually about the best a genny will do in a tack.

If you dont want to lower mast for installing new Windex.. Return to the same bridge during calm water conditions and low current. Have assistant on bridge deck. drift slowly under bridge while assistant installs new windex on mast.
A few years ago I had my spinnaker halyard rope get loose and the end was stuck in the pulley near the top of the mast. I was able to dock next to a low bridge and slowly walk the boat close to the bridge ramp where I could easily work on the mast.
Well the the bridge won today, I was chicken to go under. it was at 36ft but high tide was not for another hour and I didn't want to get stuck on the other side. So with my new prop and boat speeds finally at manufacturers specs we took her out the jetty. Went out about a mile then rode what little swell there was back in. I Love my boat.
