Details

Navigation is both an art and a science, but neither can be practised effectively unless the watchkeeper is present on the bridge, well rested and able to focus their attention on the complex task of watchkeeping.

Notwithstanding the fundamental requirement for an alert, qualified and rested watchkeeper, technology has been put in place to enhance safety by aiding the watchkeeper in their duties. Where fitted, proper use shall be made of equipment including the Bridge Navigational Watch Alarm System and zone and CPA alarms on radar and ECDIS. It is important that the equipment is used to best effect and alarms are set appropriately to support, but not replace keeping a proper lookout by all available means and proper watchkeeping practices.
