How old is the boat?
There is no rake adjustment in current Bravo rudders using EZ Loc rudders.
Current manual:
http://static.hobiecat.com/digital_assets/bravo-manual.pdf?_ga=1.265538703.1282602363.1410457879The manual indicates one additional step in adjusting the jaws... you have to pry them away from the housing:
Adjusting the angle of the Mainsheet cleat After removing the three adjustment screws from
the side of the block,
unfasten one side of the cleat by unscrewing one
of the top screws. This will allow the cleat arms to spread apart much
easier. Completely removing the cleat is not necessary. If it is removed, be sure to
note its orientation on the mounting arms.
