Starboard Go 2010 155l Mast-track recommended Setting mark position away
 

Dear Team,
On may Starboard Go 155l 2010 the black mark for mast track positioning (the recommended Setting) is gone away.
As the mark is not in the centre of the track how can I measure the recommended setting position from the tail with a 90 degrees right angle tool to get this helpful point again?
Please let me know the correct measurement in millimeter to mark this position again with a waterresistend color.
The board is really the best choise I ever did - thanks so much
Peter
