Let’s discuss some of the pros and cons of paperless navigation. Availability: One of the great advantages of ECDIS over paper charts is the availability of electronic charts – especially when voyage orders are received at the last minute.
Gone are the days when Second Mates huddled over the good old NP 131 (chart catalogue) to determine what charts they require for the voyage.
Finally, one can also use the Radar Range and Bearings to plot positions on the ECDIS display, just like on paper charts.
All types of ECDIS these days come with an option of manually plotting the position using the Range / Bearing method.
Even then there was a possibility of the occasional erroneous correction.
This is done by acquiring a fixed / stationary target such as a small island, lighthouse, rock etc.
on the Radar (ARPA) and then activating the ARPA tab on the ECDIS.
With vessels going chartless, all that the Second Mate needs to do now is plot a rough course in the voyage planner and a list of all the required paper charts is populated.
The Master then emails this list to the chart supplier, who will then send the activation codes for those charts.
Imagining that a day would come where we’d no longer have them onboard was nothing short of blasphemy.
