Future Barra Vessel Deployment Options Consultation

We welcome you and thank you for taking the time to review this public consultation. This consultation seeks to gain your views on the baseline strategic vessel deployment, disposal and cascade plan, specifically your views of future vessel deployment for the Castlebay - Oban service. Please feel free to read the document at your leisure.

CalMac and Transport Scotland colleagues will be available to assist with any queries throughout. For any comments and feedback, clipboards supplied or alternatively please email your Area Manager ian.graham@calmac.co.uk by 1 March 2026.

Overview and Background

  • CalMac issued the baseline Vessel Deployment, Disposal and Cascade Plan (VDD&CP)
    This aligns to Island Connectivity Plan (ICP) Vessels and Ports Plan.
  • This plan sets out a baseline view of how our major vessels will be deployed across the
    network through to 2028.
  • This plan is not final – it is an initial draft that we are publishing to invite discussion and
    collaboration.
  • We want to shape the final version through meaningful engagement and consultation, and
    that is why we are here today.
  • We are keen gather community views on these plans and understand your priorities
    We commit to giving updates on the progress.
  • Our goal is to ensure that vessel changes reflect community feedback and support
    wellbeing and connectivity.

Deployment Plan

  • Over the next four years, we will deploy a series of new vessels to improve capacity, reliability and resilience.
  • These deployments are carefully planned to align with infrastructure readiness, service demand, and community priorities.

The following major vessels are scheduled to enter service between 2026 and 2028:

    • Q1 2026 - MV Isle of Islay entry into service - deployed to Kennacraig - Islay
    • Q3 2026 - MV Loch Indaal entry into service - deployed to Kennacraig - Islay
    • Q4 2026 - MV Glen Rosa entry into service - deployed to Ardrossan - Brodick
    • Q1 2027 - MV Lochmor entry into service - deployed to Uig - Tarbert / Lochmaddy
    • Q3 2027 - MV Claymore entry into service - deployed to Uig - Tarbert / Lochmaddy
  • The introduction to service of MV Lochmor will result in a vessel cascade which could change deployment on Castlebay – Oban.
  • Each deployment option is supported by a detailed assessment of route needs, vessel
    capability, and operational readiness.

Redelivery Principles and Indicative Programme


Our approach to deciding vessel redelivery is guided by the following principles:

  • Prioritise older vessels to reduce the risk of unplanned breakdowns and service disruption.
  • Engage with affected communities to understand local impacts and explore alternative options.
  • Maintain resilience by retaining vessels to support maintenance or contingency planning.
  • Ensure environmental compliance through responsible disposal or repurposing.
  • Redelivery is not a one-size-fits-all process. Each vessel is assessed individually, and decisions are made in the context of wider network needs.
  • The following vessels are currently identified for potential redelivery between 2026 and 2028:
    • Q3 2026 - MV Isle of Mull redelivered (tbc)
    • Q4 2026 - MV Isle of Arran redelivered (tbc)
    • Q2 2027 - MV Isle of Lewis redelivered (tbc)
  • As MV Isle of Lewis has been identified as potential vessel for redelivery, this consultation with communities is required to ensure local views and needs are taken into consideration.
  • Once this is completed a recommendation will be made to Ministers on vessel redelivery.

 

Cascade Principles and Indicative Programme

Our approach to cascade planning is guided by:

  • Maximising operational value of existing vessels.
  • Improving service reliability on routes with older or less capable vessels.
  • Supporting community needs through targeted redeployment.
  • Maintaining flexibility to respond to changing demand or disruption.
  • Infrastructure compatibility, crew availability, and seasonal service patterns

The following cascade movements are currently planned:

    • Q3 2026 - MV Finalggan cascaded to resilience vessel
    • Q4 2026 - MV Caledonian Isles cascaded to TBC
    • Q1 2027 - MV Clansman cascaded to resilience vessel
    • Q1 2027 - MV Hebrides cascaded to Oban - Coll/Tiree
    • Q2 2027 - MV Finlaggan and MV Clansman moved from resilience vessel to TBC
  • As MV Isle of Lewis identified as potential redelivery, a cascade of existing vessel being considered.
  • The baseline plan outlines the potential redelivery of MV Isle of Lewis and the subsequent
    vessel cascade options
  • The alternative option of retaining MV Isle of Lewis is also being considered.
