  • Tattie Pier, Cumbrae Ferry Slipway

Surveys are planned to be undertaken from a small workboat and weather permitting it is anticipated works at both locations will be completed within a single day.

The survey team supervisor will monitor VHF channels 12 and 16 and liaise with the local CalMac Ferries Ltd Port Managers to ensure there is no disruption to timetabled ferry services.

All vessels navigating in the vicinity of the two locations during this time are advised to maintain a lookout for the survey vessel and proceed with caution, regulating your speed to minimise the effects of wash accordingly.
