MV Glenbrook is a double-ended, drive-through ferry, operating across the River Lee in County Cork.

She was built in 1970 as MV Lochalsh for the Caledonian Steam Packet Company and served on the Skye crossing until 1991.

In August 1969, Patrick Thomas announced a number of innovations, including the ordering of two 28-car ferries for Skye.

[2] On 23 December 1988, Lochalsh was hit by a freak wave, leaving her seaward ramp trailing in the water and the vessel impossible to steer in the 60-knot westerly wind.

[2] Lochalsh was very similar to Kyleakin which had been the first group ferry to be built outside Scotland, the first with drive-through capability and the first to be equipped with Voith-Schneider propulsion.

[2] Her Gardner diesel engines were coupled to two Voith-Schneider propulsion-units at diametrically opposed corners of her hull, making her extremely manoeuvrable.

[4] They operate across the River Lee, between Rushbrooke on Great Island and Passage West on the mainland in Cork Harbour.
