Here is the fourth and last – for the moment – of my Thames workboat articles in which I’ve tried to capture something of the essential, varied work these little boats with their skilled skippers do along the river.

As mentioned in my previous article: Thames Workboats III, MST Marine Support Thames provides a comprehensive hire service. Their workboats and small tugs, in a distinctive cream and navy blue livery, with names in shadow lettering, make them easy to spot.

On April 11, 2024, ownership of PROVOKER passed from Marine Support Thames MST Ltd. to Viscount Cruises where she has reverted to her original name, STELLA. She had been operating as a service, or a crew vessel. And on the changeover, MST Ltd. wrote in a Facebook post for her new owners: “We hope this small, little workboat will continue to serve them well for many years to come.” And as you will see further below, she is as busy as ever.

MST’s PROWLER , was built in the Delta shipyard in 1988. She is used as a light tug, a workboat for crew transfer, towing, and line running.


RAY is a Dory tender in the Port of London Authority fleet, accompanying the Driftwood crafts II and III. She is mainly used to carry people or goods between vessels and the shore.

REBEL is owned by an engineer known as Robbo, who services and maintains various boats along the Thames, including those of CPBS Marine Services Ltd.


ROMEO LIMA is one of Livett’s fleet of workboats available for a variety of work on the river including filming, and deployment as a camera boat, safety boat, drone platform or flexible vessel for river wall and foreshore surveys; and I’ve see her at work on several of these tasks. Some of the TV shows and films that Livett’s camera boats have been involved with along the rivers Thames and Medway, can be seen here.
She joined the Livett’s fleet in 2022 and is a sister vessel to Bravo Lima GB with “one key difference: the inclusion of a wheelhouse… She has the space for up to six passengers and two crew.”


ROSE STEEL, jointly owned by Gordon McCann and Dan Adams, Captain of M.V. CONNAUGHT, was bought from Parker Marine last year. She is based at Richmond.


SARAH LEE is owned by London Party Boats Ltd. and I see her most days working along Lambeth Reach.

Owned by Collins Waterage and Lighterage, SIBERIAN was once called OPUS ONE. She has recently been acting as a safety boat for engineers working on the Jack-up barge at present installed next to the Palace of Westminster.


Owned by Hart Marine Services since 2012, SIR HENDRIK operates throughout the Thames and adjoining rivers and creeks, towing barges, houseboats, yachts and a number of historic vessels. She is available as well, for civil engineering and bridge repair attendance, also for safety boat duties.
She is registered as a National Historic Ship.

Another familiar sight along the central London Thames are the *Dogs* of CPBS Marine Services Ltd. In the picture above is the very manoeuvrable open workboat SNOOP DOG, used for carrying crew and personnel along the river, as well as ship’s mooring and various site duties. She’s tied up next to WATCHDOG (see further below).

Now operating under her original name, STELLA is busy transferring crews to and from Westminster Party Boats’ moorings.

TYBURN is a Port of London Dory tender used with Driftwood craft II and III, for transferring workers when in use for clearing debris, maintenance of moorings and other tasks.



These workboats, some belonging to a company, some to individuals, are ever present on the River Thames. Like filaments holding together the web of river transport, they can be overshadowed by larger vessels but as in the old days with lighters, working without them the system would cease to function.
