Step Four. Check compass alignment by running the boat 180 degrees from the heading used in step 2. If the compass
is not correct at this time, there is an alignment error. To correct, rotate the compass itself to remove one half of this error.
Repeat steps 1, 2 & 4 until your North/South line is correct then repeat step 3.
Step Five . Upon completing the procedure, secure the compass in its final position.
V-57, V-57W, V-57.2, V-57W.2 S-53, S-53G, S-53W, S-53-A & RA-93
These models incorporate a compensation system that work on the intercardinal heading instead of the cardinal heading.
You can use methods 1 or 2 to compensate these models but you will need to use different headings than are listed.
For example in steps 1 and 2 of both methods, you are asked to select a course that is within ten degrees of the
North/South line. For these models, you will select a course that is with in 10 degrees of the NorthEast/SouthWest line (a
heading of 45 or 235). Use the port compensator (slot is on the left) for your adjustments.
For steps 3 and 4 of both methods select a course that is with in 10 degrees of the SouthEast/NorthWest line (a heading
of 135 or 315). Use the starboard compensator (slot is on the right) for you adjustments.
ALL Models
If you feel that the deviation on your boat is of an unusual nature, the services of a professional compass
adjuster will be a wise investment.
To assure accuracy on all headings, check for deviation every thirty degrees and record any deviation on a deviation card.
We recommend checking at the start of each boating season, and any time new equipment is added near the compass,
for deviation.
Maintenance
Protect your compass from the sun when not using your boat. Strong sunlight may decrease the life of your compass.
Ritchie compasses require very little care. To remove salt spray deposits or dirt, rinse the entire compass with clean,
fresh water and wipe carefully with a damp cloth.
Important Note: Never Use Chemical or Abrasive Cleaners.
