Compass Adjustment

A compass adjusting service for all types of vessels.

Paul Cunningham has now logged compass adjustments for over 2,100 compasses.   

During the service to adjust your vessels magnetic compass we shall perform the following;

  • Check the compass position, fitment and quality of operation.
  • Then you or your skipper will take the vessel to sea in order for us to fully complete a coefficients determination.
  • We will do this by swinging compass, thereby putting the vessels’ head onto known bearings and/or transit position lines.
  • We will adjust and compensate the compass for minimising the detected deviation.
  • Then we will prove the compass deviations that we have calculated and observed.
  • We will then create tables of deviations and coefficients that we will leave with you on the vessel for immediate use and follow with PDF copies for the ships files.
  • Please allow 2 hours at sea for each vessel to accomplish this service.
  • Any extra added compensation magnets and/or soft iron may be charged in addition, at cost.
