Loch Katrine

The project to build seven new "Loch Class" ferries is part of CalMac's Small Vessel Replacement Programme (SVRP), aimed at replacing the aging small vessels on short-crossing routes. The contract was awarded to Remontowa Shipbuilding in Poland in March 2025, with construction commencing later that year. These new, fully electric ferries are designed for increased capacity and resilience and are scheduled to begin entering service on key routes across the Clyde and Hebrides ferry network starting in 2027.

The Small Vessel Replacement Programme (SVRP) Phase 2 is currently navigating its concept design and feasibility stage, which kicked off following the appointment of naval architects in December 2024. This phase encompasses crucial assessments regarding hull forms—with a double-ended monohull emerging as the preferred option—as well as ongoing evaluations of vessel speeds, carbon footprints, and various car deck and accommodation layouts. A major focus is being placed on infrastructure compatibility; while shore power has already been deemed acceptable for Ardmhor, the feasibility of shore charging for the Sound of Harris remains under investigation alongside grid resilience discussions with SSEN. Additionally, project partners are engaging with the Maritime & Coastguard Agency to explore lifting the current daylight operating restrictions on the Sound of Harris.

​While the technical groundwork is actively advancing, the ultimate timeline and delivery of the fleet hinge on upcoming governance and funding decisions. The vessels are slated for delivery in Phase 2 of the Islands Connectivity Plan (2026 to 2031), with estimates targeting 2029/30 to accommodate standard design, build, and public procurement timelines. However, formal resource allocation has yet to be finalised. Project teams are currently building a robust business case to ensure the programme is tender-ready as soon as capital is secured, though the realisation of the phase remains subject to approvals from Scottish Ministers and the Scottish Parliament following the May 2026 elections.
