Namely, in the video, CHIRP presents three cases.
In the first case, it describes an encounter between a yacht and a large passenger vessel, where navigation lights were difficult to distinguish amongst other deck lights.
The second case a poorly designed bridge wing platform, caused a serious hazard for a pilot, which had the potential for a fatal fall from height.
For the last case CHIRP presented the case of yacht which had suffered engine problems while on passage and the skipper requested a tow from the mouth of the river to his berth at the yacht club. A considerable swell in the entrance of the river resulted in a rigid inflatable boat (RIB) and the yacht to be pulled apart and then back together with quite some force.
