Incident while on passage of Rotterdam
Following the rules for small ships passage of Rotterdam we were advised by Maas Traffic Center to carry on across the major traffic lanes.
Just before our passage M/S Blue Master approaching Rotterdam on our port side was on collision course.
We overheard a discussion in Dutch between Maas traffic center and Blue Master on VHF Ch03 and allthough not understanding Dutch we heard the name Dora Mac mentioned several times. Coming closer to collision we tried to reach Blue Master on VHF Ch 16 and the traffic centrer on Ch 03 without success. Blue Master then turned to starboard and the situation came under control.
Probably Blue Master was advised to pass aft of Dora Mac but it would have been valuable for us to be informed.......
