Who We Are

TRUSTED
ON THE
CLYDE.

Line handling operations for some of the largest vessels to navigate the Firth of Clyde.

Our purpose-built HDPE workboats deliver professional line handling services to some of the largest and most demanding vessels in UK waters, alongside marine engineering callouts, emergency towing, and breakdown response for private yachts and leisure craft. Fully trailerable, our workboats are equally at home on inland waters and lochs throughout Scotland.

Our clients include commercial shipping operators, the Royal Fleet Auxiliary, and the Royal Navy — organisations that demand precision, reliability, and professionalism in every operation.

Why Dubh Mor

THE RIGHT
TEAM.
THE RIGHT
BOAT.

01

Specialist Focus

Line handling is what we do — not a sideline. Our crew, kit, and workboats are dedicated entirely to safe, efficient marine operations.

02

Naval Standard

Operating with RFA and Royal Navy clients means our procedures and safety protocols meet military-grade expectations every time.

03

Local Knowledge

Loch Striven and the Clyde are our home waters. We understand the tides, conditions, and demands of this operationally unique environment.

04

Always Ready

Commercial operations don't keep office hours. Neither do we — fully trailerable, we can mobilise to inland waters and remote locations across Scotland at short notice.
