The Marine Accident Investigation Board is looking into how a cruise ship clipped four yachts during a manoeuvre to turn her around in Dartmouth harbour.
Superficial damage to the yachts was caused by the Saga Pearl II, which was being escorted by a tug and piloted by harbour master Captain Mark Cooper. The 18,500 ton, 539ft-long ship was then berthed on the mainstream moorings in the River Dart, on Wednesday morning.
A spokesman for Dart Harbour said: “No one was hurt in the incident and the harbour office is now making all efforts to contact the owners of the yachts involved.
“Records from the incident are being collated and will be analysed in order to identify exactly why this occurred and what can be learnt.”
A spokesman for the MAIB confirmed they are aware of the incident and are looking into the circumstances of what happened.
The Saga Pearl II arrived in Dartmouth for the start of the 174th Port of Dartmouth Royal Regatta.
Coming from the Isles of Scilly, the Saga Pearl II was due to leave for Dover on Thursday afternoon.
Up to 500 guests on board were entertained on board by Dartmouth town crier Lez Ellis. As well as choosing from a variety of local excursions there was plenty of time for passengers to take in the town and enjoy the opening ceremony and first official day of the regatta.
The mayor, Cllr Rob Lyon, and mayoress Di Lyon met Saga Pearl II’s captain for an exchange of plaques to commemorate the visit.
