PDF | 335.123kb
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.
The following major vessels are scheduled to enter service between 2026 and 2028:
Our approach to deciding vessel redelivery is guided by the following principles:
Our approach to cascade planning is guided by:
The following cascade movements are currently planned:

Factors and Impacts |
|
|
1 |
Redeliver MV Isle of Lewis when MV Claymore enters service |
Vessel Age |
31 years (built in 1995) |
|
Vessel Condition |
Nearing the end of her service life therefore increased risk of breakdown due to aging vessel |
||
|
Freight and Livestock |
Current limitations related to carrying dangerous goods remain due to enclosed car deck |
||
|
Network Impact |
Alternative vessel disposal option to be considered |

Factors and Impacts |
|
|
1A |
Deploy MV Finlaggan to Castlebay - Oban |
Vessel Age |
15 years – built in 2011 |
|
Vessel Fit |
Desktop assessment demonstrates adequate berth fit, to be confirmed through berthing trial. |
||
|
Capacity and Utilisation |
21% decrease in car carrying capacity.
Forecasted average utilisation Summer 2027: 64% |
||
|
Freight and Livestock |
Current freight can be shipped and benefit of increased range of dangerous goods that can be shipped due to open car deck.
Capable of carrying livestock |
||
|
Weather Resilience and Technical Cancellations |
MV Finlaggan has demonstrated reliable performance in adverse weather conditions on Islay and Little Minch routes
13% technical cancellations in 2025 |
||
|
Timetable |
Passage time would increase circa 10 – 15 mins each way due vessel speed of 16.3 knots
Turnaround time expected to be maintained subject to trial |
||
|
Network Impact |
MV Clansman sole resilience vessel for major vessel fleet |
||

Deploy MV Clansman to Castlebay - Oban |
Vessel Age |
27 years – built in 1998 |
|
Vessel Fit |
Suitable fit, operates service weekly in summer |
||
|
Capacity and Utilisation |
22% decrease in car carrying capacity
Forecasted average utilisation Summer 2027: 65% |
||
|
Freight and Livestock |
Current freight can be shipped and benefit of increased range of dangerous goods that can be shipped due to open car deck
Capable of carrying livestock |
||
|
Weather Resilience and Technical Cancellations |
MV Clansman has demonstrated reliable performance in adverse weather conditions on this route and main route Coll/Tiree
30% technical cancellations in 2025 |
||
|
Timetable |
Passage time would increase circa 10 – 15 mins each way due vessel speed of 16.5 knots
Turnaround time expected to be maintained subject to trial |
||
|
Network Impact |
MV Finlaggan as resilience vessel |

|
|
1C |
Deploy MV Glen Rosa to Castlebay - Oban |
Vessel Age |
Due to be delivered in Q4 2026 |
|
Vessel Fit |
Desktop assessment demonstrates adequate berth fit, to be confirmed through berthing trial.
Further analysis of displacement subtility being carried out |
||
|
Capacity and Utilisation |
22% increase in car carrying capacity
Forecasted average utilisation Summer 2027: 43% |
||
|
Freight and Livestock |
Current freight can be shipped, likely to result in increased range of dangerous goods that can be shipped due to open car deck
Capable of carrying livestock |
||
|
Weather Resilience and Technical Cancellations |
Sister vessel performance has demonstrated weather resilience although vessel has yet to be deployed on exposed route
14% technical cancellations in 2025 (MV Glen Sannox figure) |
||
|
Timetable |
Passage time would increase circa 10 – 15 mins each way due vessel speed of 16.5 knots
Turnaround time expected to be maintained subject to trial |
||
|
Network Impact |
Full network impact and resilience vessel to be confirmed |

|
Capacity and Utilisation |
Car carrying capacity as per current
Forecasted average utilisation Summer 2027: 51% |
||
|
Freight and Livestock |
Current limitations related to carrying dangerous goods remain due to enclosed car deck |
||
|
Technical Cancellations |
32% technical cancellations in 2025 |
||
|
