Many thanks to Captain Geoffrey S. Vale, MNI, MA (Mar.Hist), Master Mariner, Argus Marine Surveyors Ltd. for this historical perspective on the collision between the Sun Diamond and Erawan...

In the early hours of September 25, 1973 the 19,316-tonne deadweight cargo vessel Sun Diamond, in ballast condition, was inbound to Vancouver, B.C. In the vicinity of the West Point Grey Buoy, she was in collision with the 15,190-dwt Erawan outbound from Vancouver with a partial cargo of potash.

Both vessels were similar in many respects -- the Sun Diamond had a length overall of 147.2 metres and beam of 19.23m, whilst the Erawan was 141.05m with a beam of 20.58m, their summer load-line draughts were similar at around 8.40m. Both were diesel powered, the Sun Diamond having 8,000hp and 14.25 knots, the Erawan had 7,500hp and 15 knots.
