The annual exercise to crane the boats back into Tenby harbour waters will get underway during the early hours of Monday morning (March 31).
Vehicle owners are advised to leave clear access in the Penniless Cove Hill and Castle Square areas on Sunday night, to facilitate the arrival of the large crane for the lift-in at the harbour car park at around 4am.
The sight of the vessels being lifted back into the sea, traditionally draws spectators viewing from vantage points around the picturesque harbour, and is seen as a date in the calendar to mark the official start of the holiday season in the seaside town, ahead of the Easter holidays in April.
