Annual Digest <strong>2016</strong><br />
This section contains some classic examples of<br />
COLREGS-RELATED incidents, plus some fresh cases<br />
involving ECDIS. It ranges widely, from a ship being<br />
overtaken from dead astern by a vessel that did not<br />
make its intentions clear, to a crossing situation where<br />
vessels disagreed over what constituted a safe passing<br />
distance. A near miss between a yacht and a merchant<br />
ship sheds light on the difficulty of detecting the<br />
lights of a sailing vessel at night, while a ship at anchor<br />
does not notice it is dragging despite two radar<br />
alarms. That ship delib erately immobilised its engines<br />
despite being anchored in a strong current, and the<br />
engineers were reluctant to use them because they<br />
had not been properly warmed through. Readers can<br />
ponder that old conundrum – is it better to decide<br />
against using the engines and risk damaging the ship<br />
in a collision, or risk damaging the engines to avert the<br />
collision? Sometimes, the correct answer only<br />
becomes apparent with the benefit of hindsight.<br />
There are also two cases where ECDIS features pro -<br />
minently. They raise the familiar topics of training and<br />
familiarisation, and the different types of display that<br />
can be selected. One case features a navigator who<br />
wanted to sail through the Nab Tower and underlines<br />
the importance of proper passage planning and the<br />
need for careful checking by senior officers.<br />
Finally, we include another very useful MAB Insight<br />
piece about manoeuvring in a seaway. It covers several<br />
of the points that have emerged in our two sections<br />
about COLREGS, and should be carefully studied by all<br />
deck officers, DPAs etc.<br />
