As a result of this collision, the Disciplinary Court notes that special attention for shipping vessels approaching from behind is important when sailing at relatively low speed in a busy navigation area. It is thereby recommended that the radar be set to “radar centre” (and not to “radar off centre”), in order to maintain good visibility behind the vessel.

The Disciplinary Court advises bridge teams to use both radar systems if the vessel is equipped with an X-band and S-band. Due to the different properties of both systems, objects can come through better on the one system than on the other. This includes Racon signals and objects in a shower. Furthermore, a comparison of the two radar systems can provide a better interpretation of the data obtained from the systems.

Knowledge of radars/AIS/ECDIS and their integration should be improved. AIS remains visible on radars that are on standby.

A chart for use as a means of navigation is only valid as a means of navigation if it has been issued by or on behalf of an authority, hydrographic service or other relevant official body. Any means of displaying maps may be in support of navigation, but shall never serve as a primary means of navigation (as referred to in Solas Ch V, reg 19-2.1.4).
