Maritime Museum.
From the website of the National 
Maritime Museum, "the house flag of Clan Line Steamers Ltd (Cayzer, Irvine & 
Co., Ltd), London and Glasgow. A rectangular red flag bearing a white diamond 
with a red rampant diamond in the centre. The flag is made of a wool and 
synthetic fibre bunting with a linen hoist. It is machine sewn and the design is 
printed. A rope and two Inglefield clips is attached.
The shipping line was founded in 1878 by Charles Cayzer to run direct passenger 
steam services between Bombay and the UK via the Suez Canal as Cayzer, Irvine & 
Co., Liverpool. The company vessels all had names with the prefix 'Clan'. 
Services were extended to South Africa in 1881 and in the same year the company 
opened a larger office in Glasgow. Clan Line Steamers Ltd was launched in 1890 
and the company extended its routes in the Persian Gulf and to North America - 
it was by now also carrying cargo. Cayzer Irvine & Co. was incorporated in 1907 
but remained in the hands of the Cayzer family.
After the death of Charles Cayzer in 1916, the business was continued by his 
sons. By the late 1930s it was the biggest cargo carrying concern in the world. 
The fleet inevitably sustained losses in both world wars. The Thompson Steam 
Shipping Co. was acquired in 1952. The company changed over to motor ships in 
the 1950s. With the advent of containerization, the company ran down the 
shipping side of the business in the early 1980s, having diversified into other 
business ventures. 'Clan Macgregor' made the final Clan Line voyage in 1981."
Jarig Bakker, 9 August 2004
Larousse Commercial Illustré (1930) shows Clan Line, London: red, a white 
diamond with a red lion rampant. The diamond's points are about one fifth of 
flag height away from the flag's edges. The illustration here shows a smaller 
diamond.
Evans (1959) in 'The Observer's Book of Flags' 
mentions on p. 188 the "*Clan Line*, whose ships also wear Jacks displaying the 
respective tartans after which they have been named". Compare, however, with G.H. 
Watt's comments under 'British and Commonwealth Shipping Co., Ltd.' 
In any case both agree on a very large diamond, Evans by showing one and Watt in 
his comments. A similar version here:

I purchased a very old ensign flag and all that is written on it is "commodore", it is very well made and very old and smells very musty. I purchased it on the south coast near Portsmouth in the UK.
Russell Crowe, 30 March 2014
This flag has the same pattern as the Clan Line. Could it be swallow-tailed to indicate a commodore, if shipping lines have commodores?

by Klaus-Michael Schneider, 15 May 2009H. Clarkson & Co. Ltd. The flag, as shown by Stewart 1963 and Loughran 1979 is blue with a 
white saltire surmounted by a red shield edged white and bearing a yellow "C" 
[see below]. 
Neale Rosanoski, 15 June 2004
Clarksons was established in the 19th century during the era of sailing 
ships. Its rise began, when the company became exclusive broker for 
ESSO/Standard Oil Co. 
Description of new flag:
It is a 43-stripes 
flag with alternating dark blue (B+) and white horizontal stripes. Furthermore 
the flag is divided by a white saltire superimposed by a right rectangle which 
contains a white, serifed capital “C”. Though the stripes might be all of equal 
width, sometimes it seems, that the blue stripes are slightly wider.
Source: 
I spotted this flag on 12 April 2009 at Johannisbollwerk in Hamburg on top of 
the company’s HQ.
Klaus-Michael Schneider, 15 May 2009
From 
http://www.clarksons.co.uk/history.html, "Since its foundation in 1852 the 
Clarkson PLC Group ("Clarksons") has grown into one of the world’s largest 
shipping services groups, employing nearly 300 people including 200 in London.
(.....)
In recent years the group has expanded from its ship-broking origins into a 
fully integrated shipping services provider covering such activities as research 
and consultancy, shipping publications, the provision of shipping finance, ship 
valuations and ship owning activities."
A photo of an actual flag turned up on 
e-bay in 2005, showing slight difference from the rendering above. I think I've 
seen the multi-striped flag on the net before, but nowadays the firm's website 
shows another variant.

Clyde Marine Services Ltd of Greenock, on the namesake river leading to 
Glasgow, is a maritime service provider. Website, showing the house flag – a 
pennant, really: 
http://www.clyde-marine.net.
Quoting from the ‘About Us’ section 
(upper menu): 
“The company was established in 1913 to provide a 24 hour 
reliable, efficient and all-weather ship/shore service for the many shipping and 
shipbuilding industries based upon or visiting the Clyde for ship trials. (...) 
Four generations of Munro family have steadily directed and expanded the 
business into tugs, ferries, passenger tenders, charter cruise vessels, and 
provide the vital harbour services of boatmen and riggers. Our fleet of vessels 
provide mooring, boarding and towing services around the clock, assisting ship 
movements within the Clyde area. The main focus of operations covers the river 
from Glasgow to the Firth of Clyde although contracts frequently extend to the 
islands, lochs and harbours on the West Coast of Scotland."
CMS operates 
six harbour and two coastal tugs, five personnel tenders of various sizes, and 
four mooring launches – see ‘Our Fleet & Equipment’ (upper menu) for additional 
details.
The house pennant is divided per 
saltire: black (hoist), yellow (top), blue (fly), and red (bottom).
This 
pennant is prominently shown over the site and is also painted on some vessels.

Clyde Shipping Co. Dating from 1815 it originally used a double pennant of 
[1] yellow edged red except at hoist and bearing a red lion rampant and [2] 
green edged red except at hoist and bearing a yellow Irish harp though some sources do not show the edgings. The change to the blue 
pennant with lighthouse and letters is noted by Brown 1926 onwards whilst Brown 
1982 and 1995 show it without any lettering indicating a change towards the end 
of its shipping interests which became towage only which was acquired by Cory 
Towage in 1995. By 1998 the company had become Clyde Marine plc and today is 
mainly involved in manufacturing gear for leisure marine craft.

Two merchants from Glasgow and Greenock formed the Clyde Shipping Co in 1815. 
The company acquired two paddle steamers, "Industry" and "Trusty", to sail the 
river Clyde as luggage boats and lighter tugs. In 1856, the partnership was 
dissolved and sold to a new partnership formed mainly of the Kidston family, who 
were ship owners and steel stockholders in Glasgow. The new firm acquired 
several new vessels including two tugs, "Flying Childers" and the "Duke of 
Northumberland", and two coasters, "Vivandiere" and "Killarney". With the 
latter, a regular service to Ireland was initiated and soon after the firm sold 
its luggage boats to the previous firm's agent and manager in Port Glasgow, 
James Steel, who went on to form Steel & Bennie, tug owners. An additional 
partnership was formed in 1856 under the name of the Glasgow Screw Steamship Co 
to manage the growing Scotland-Ireland coasting trade and the two companies 
operated under virtually the same management. By 1880, the companies owned 14 
tugs and 10 coastal steamers and by this point the board of directors of each 
company was identical. In 1881 a new partnership agreement was drawn up to 
amalgamate the interests of the two companies under the name of the Clyde 
Shipping Co .
Between 1867 and 1886 the company acquired the towage 
businesses of the River Towing Co, Greenock, in 1867; Port Glasgow Towing Co, in 
1880; Glasgow Screw Tug Co, in 1881; Queenstown Towing Co Ltd, Cobh, Ireland, in 
1886 ; and M Langlands & Sons' Clyde-Plymouth interest in 1886. In 1884, the 
company began regular runs to London.
In 1893, it assumed limited liability 
as Clyde Shipping Co Ltd with a capital of £500,000 and George Jardine Kidston 
as chairman and James Cuthbert as managing director. At this time, the company 
was operating 15 coasters and 25 tugs. It also had 2 deep-sea tramps that dealt 
with foreign trade, often with islands in the Pacific Ocean.
In 1912 the 
company purchased the Waterford Steamship Co, and, when the Cork Steamship Co 
experienced difficulties in the period immediately after Irish partition, it 
reorganised part of that business as the British & Continental Steamship Co Ltd.
The 1914-1918 World War saw the Government requisition some of the company's 
fleet for a short period but the majority of the fleet continued in the service 
of the company; 8 coasters and 6 tramps were lost due to enemy action and its 
remaining tramp was sold in 1915.
The 1939-1945 World War saw the loss of 2 
coasters and 1 tug. During both wars the lives of 200 employees were lost.
In 1944, Clyde Shipping Co Ltd were partly responsible for the formation of 
London Scottish Lines Ltd, which had evolved through a series of agreements 
between themselves, London & Edinburgh Shipping Co Ltd, General Steam Navigation 
Co Ltd and Carron Co, iron masters, to trade between Grangemouth and Leith on 
the east coast of Scotland and London.
By the mid 1950s, Clyde Shipping Co 
Ltd had only one vessel that carried passengers on the Liverpool-Waterford 
service. Since the company's formation it had always carried passengers, mainly 
between Britain and Ireland. Many of these travellers in the early years were 
steerage emigrants, but from 1900 onwards they were holiday-makers and carriage 
conditions were much improved. Following the 1939-1945 World War, the decision 
was taken to cease the passenger trade except between Liverpool and Ireland and 
this had ceased by the late 1950s.
The company acquired and managed a 
number of subsidiary companies from the 1960s onwards. These included Ross & 
Marshall Ltd, shipowners, established in 1907 in Greenock; Glenlight Shipping 
Ltd, ship managers, established in Glasgow in 1968 as a subsidiary of Ross & 
Marshall Ltd and transferred to Clyde Shipping Co Ltd in sometime in the 1970s; 
Clyde Shipping Tugs Ltd, ship owners, Glasgow, previously Light Shipping Ltd, 
acquired in 1973; and William Campbell (Port Glasgow) Ltd, coal merchants, 
established in 1947 and acquired by Ross & Marshall Ltd prior to 1966.
In 
1964, the company entered into the Waterford Consortium with Atlantic Steam 
Navigation Co Ltd, Preston, and George Bell & Co Ltd, Dublin. The consortium was 
to operate the Preston to Waterford, container service. Clyde Shipping Co Ltd 
managed the service with the Atlantic Steam Navigation Co Ltd acting as the 
Preston agents, and George Bell & Co Ltd acting as charting agents. Clyde 
Shipping Co Ltd also provided the staff at Waterford harbour. The consortium was 
a success but Clyde Shipping Co Ltd sold its 1/3 share to George Bell & Co Ltd 
in 1974.
The company was still active in 2002 as a leisure marine group and 
as part of Clyde Marine plc, holding company and producer of shipping deck 
equipment and rigging for leisure marine boats and was still based in Carlton 
Place.
