MV Loch Sunart (ex-Gemeente Pont 23 then Sound of Scalpay) was a car and passenger ferry, originally operated in Amsterdam, and then by Western Ferries across the Firth of Clyde between Gourock and Dunoon in Scotland until October 2013.

In 2018, Loch Sunart was converted into an ROV support vessel and is now owned by Caldive.

[1] In the mid 1990s, she and her near sister Gemeente Pont 24 were purchased by Western Ferries for service on the Clyde.

[6] On the acquisition of two brand new ferries in October 2013, Scalpay and Sound of Sanda were sold to The Underwater Centre, Fort William, Highland for conversion to dive barges for the training of commercial divers.

[2] In July 1995, as Sound of Scalpay, she entered service on Western Ferries' Clyde service between McInroy's Point (Gourock) and Hunters Quay (Dunoon), replacing the former Sealink ferry Sound of Seil.
