NorthStar Navigation NS3300 manual Problem drifts off GPS course

Page 43

Problem: after a sideways current or wind, the correction is applied too quickly or too slowly

If the boat encounters a sideways force, then it will move off course sideways. The Pilot will automatically bring the boat back to the correct heading by applying a few degrees of rudder, called trim. Trim gain sets how quickly the trim is applied. Trim gain should be adjusted to trim the boat in about one minute. Getting the Trim gain setting right can be difficult for your specific boat and it is easy to alter the Trim gain too much. Change the settings slowly and conservatively at first, until the right settings are known.

aBoat takes much more than one minute to trim

Sideways force starts

Increase trim gain

1 minute

bBoat takes much less than one minute to trim Sideways force starts

Decrease trim gain

1 minute

Problem: drifts off GPS course

or	Increase GPS gain.

Problem: boat oscillated around GPS course

or	Decrease GPS gain.
