Sailors and navigators are being urged to exercise caution after a vessel ran aground on rocks beneath the Great Orme at Llandudno.

The warning has been issued by Conwy's Harbour Master Matthew Forbes following the grounding of the vessel Vanguard II.

In a notice circulated through the North Wales Cruising Club, Mr Forbes said: “All mariners are advised that the vessel Vanguard II is presently lying on the shore at the Great Orme, latitude 53° 19.9’ north, longitude 3° 52.5’ west.

“As of 0930 this morning, it was still afloat with one engine running. The vessel represents a potential navigational hazard should it float free and mariners are advised to keep a good look-out when navigating in Conwy Bay.”

The incident occurred off the limestone headland of the Great Orme, a well-known landmark at the entrance to Llandudno Bay. The area is popular with leisure sailors, fishing vessels, paddle sports enthusiasts and sightseeing boats, particularly during the summer months.

Maritime users are being advised to remain vigilant and monitor navigation updates while passing through the area.

The exact circumstances surrounding how the vessel came to be stranded have not been confirmed.

The Great Orme coastline is known for its rocky shoreline and strong tidal conditions in places, with mariners regularly reminded to exercise caution when navigating close to shore. Conwy Bay also experiences significant tidal movements which can quickly alter conditions around grounded vessels.

At the time of the latest update, the vessel remained on the shoreline and authorities were continuing to monitor the situation.

Any further navigation warnings or updates are expected to be issued through the Harbour Master and maritime safety networks serving the North Wales coast.
