Unit 13-a

Task. Read and translate the following bridge check list. Be ready to retell in what cases the master should be called. Think over what other checks you can include into the following check list.

B13 Calling the master

The OOW should notify the master immediately:

	if restricted visibility is encountered or expected
	if traffic conditions or the movements of other ships are causing concern
	if difficulties are experienced in maintaining course
	on failure to sight land, a navigation mark or obtain soundings by the expected time
	if, unexpectedly, land or a navigation mark is sighted or a change in soundings occurs
	on breakdown of the engines, propulsion machinery remote control, steering gear or any
	essential navigational equipment, alarm or indicator
	if the radio equipment malfunctions
	in heavy weather, if in any doubt about the possibility of weather damage
	if the ship meets any hazard to navigation, such as ice or a derelict
	in any other emergency or if in any doubt

Other points

Be aware!

Note These checklists have been included as a guide

Masters and navigating officers may wish to add to or modify these checklists to suit the particular operational needs of the ship

Task. What modifications would you like to add basing on your own experience if any or basing on theoretical knowledge taken from your course of study?
