3 crew ran through advanced navigation practise, starting with a mooring exercise to get a stable platform to work from, then shooting compass bearings for conversion from magnetic to chart bearings, confirmation of chart bearings by radar bearings and plotting the location useing 3 x 3 bearing sets.
We then ran live radar bearings and ranges on blind transits in the mana approaches area and Titahi Bay
