Keep records of a vessels position and the related estimate of accuracy

Recognise compass errors and taking appropriate remedial action

Conduct performance checks of navigation position fixing instruments and systems

Work collaboratively with other shipboard personnel when determining the position of the vessel estimating accuracy of the position and allowing for compass errors

Carry out calculations involved in

i fixing a vessels position

ii making allowances for random instrument system and data errors

iii determining compass errors

iv estimating the accuracy of the fix of a vessels position

Use compasses and other relevant instruments when fixing the position of a vessel
