The Art of Dredging

Dredging and shipping

Captain's standing orders - calling the master

 

Standing orders for calling the master are a compulsory in every wheelhouse. Those standing orders are written by the master and should be read (and signed) by the watchkeeping officers..

This one (hereunder) is partially based on the "Bridge procedures Guide", but contains some personal pet subjects, and it is written specifically for a trailer dredger.
