As far back as
1907 the puffer owner Ross & Marshall Ltd were granted dredging rights from
the Crown Commissioners to dredge sand from Lochs Etive, Sunart and Linnhe. The
sand was sometimes brought back to Glasgow to improve the traction of tram car
wheels in icy conditions but it was often not of a sufficiently good quality to
be used for concrete. Shell sand dredged off Cockle Strand Beach on Barra was used for decorative purposes
for a period.
Clyde ‘puffers’
engaged in aggregate dredging would anchor over their chosen dredging area /
sand bank, sometimes also using ground tackle fore & aft to keep the vessel
from yawing whilst still afloat. A patent bucket grab on a single swinging
derrick was used to grab the cargo from the seabed and when swung inboard a
triggered release dropped its load over a simple screening arrangement
consisting of a portable angled steel mesh which caused any oversized material
to roll overboard, letting the required sand to fall through into the ship’s
cargo hold. Albeit as part of a much more sophisticated set up, this screening
principle can be found on the screen decks of the most modern aggregate
dredgers. An excellent photograph showing the G & G Hamilton’s ss
Rivercloy loading as described can be found on page 76 of Len
Paterson’s book “The Light of the Glens”.
Loading would continue over the low water
including, as often happened, when the vessel grounded. The water in the wet
sand cargo hold would “leak” into the bilges which were kept clear by the use
of a “blower” or steam ejector which cleared the bilges of water. The holes
left by their excavations were quickly filled by the subsequent tides. Loading
rate was some 20 tons per hour and cargoes varied between 80 and 150 tons.
The puffers were
manned by a crew of three or four depending upon whether the puffer was a
“shorehead” or “outside” boat i.e. working in sheltered or less sheltered
waters. In the early days, crew certification was not required and seldom held.
Deckhands often started as cook and also relieved as enginemen whilst most
Skippers started as enginemen so had a useful grounding in machinery.
The exact date of
the earliest aggregate dredging in and around the Clyde is unclear with the
earliest record found being Ross & Marshall Ltd’s 1907 sand dredging rights
awarded to them by the Crown Commissioners for three Lochs Etive, Sunart and
Linnhe. Ross & Marshall were very active in the general cargo trade in the Clyde and west Highland communities and it was not uncommon for
vessels which had taken a cargo outwards from Glasgow to return with a cargo of dredged sand.
The steam puffer ss
Forward, built in 1896 at Kevin Dock, Maryhill “for Holy Lock owners”
is photographed off Port Glasgow loaded with a cargo of dredged sand. The Forward
was sold to Rea & Company for work on the river Mersey “after the first world war” so it may be
assumed that she was engaged in aggregate dredging before 1914
Dredging in the
river Clyde was being carried on by Alexander Mc Neil
of Greenock in 1951 as on 19th April that year whilst
his 23year old son was skipper on the puffer Petrel which was dredging
for sand off Cardross when there was an engine room explosion. The blast blew
young Alexander about 15metres into the sea from where he was picked up by his
two fellow crew members who had abandoned ship in the ship’s dingy. The three
were picked up by a passing ship as they were rowing across the Clyde to Port Glasgow.
At a cost of some £2000, the 96ton Petrel
was built in 1897 for a James Burrows of New City Road in Glasgow . She saw service at Scapa Flow between 1914 and 1918 after which she was sold to Warnock of Paisley
sometime in the 1920s. Later she was sold on to McNeil of Greenock and employed
on sand dredging.
Other companies
variously engaged in aggregate dredging were G & G Hamilton and J & J
Hay which companies amalgamated in 1963 to form Hay Hamilton Ltd. In 1968 Hay
Hamilton merged with Ross & Marshall , forming a new company called Glenlight
Shipping Ltd.
In his book ,The
Clyde Puffer, Dan McDonald records that vessels “….belonging to Warnock & Sons of Paisley… besides engaging in
ordinary trading practices, dredged millions of tons of sand in the Clyde
estuary to bed Glasgow’s paving stones..” Warnock & Sons operated a
number of vessels including the steam puffers. McDonald also reports that “…the shell sand (dredged) from the cockle strand at Barra was
favoured for decorative purposes.
Anecdotally, it
has been said that McNeil’s were an established puffer company who started in
the aggregate dredging trade when they realised that some of the material they
were dredging to keep the river Clyde’s navigation channels open was of a
quality which could be sold to the building trade. Known as “Hattie”, Alexander
Mc Neil started his business in Albert Harbour in Greenock before moving to Victoria Harbour when Albert Harbour was filled in the 1960’s.
Sandy McNeil was
operating two steam puffers, ss Ardfern and ss Colonsay as aggregate
dredgers when, in 1966, Holm Sand purchased the Alexander McNeil company and
immediately scrapped the Ardfern as she was considered unsafe
and beyond repair. The 1910 built 96grt Ardfern was built by McGregor at
Kikintilloch and was owned by Warnock of Paisley when purchased by McNeill.
There were two puffers named Colonsay by McNeil. The first was
the ex VIC 63 which was purchased in 1956 and lost off Castlebay on
the Isle of Barra on 9th November 1960 (where she was probably not
working as a dredger???). She was replaced by the second Colonsay in 1962 which
was purchased as the VIC 84 from the Admiralty and traded
as an aggregate dredger until sold in 1966.
Colonsay the first???

With Michael
Brown at the helm at Holm Sand, it was his intention to see Alexander McNeil
Co. establish a network of aggregate depots along the west coast of Scotland .
This plan never fully came to fruition but over time the Portway,
Norstar and Norleader did trade in the Clyde operation where some major
contracts were undertaken, including material for the A8 Greenock to Glasgow
road, the power station at Inverkip and some 150,000 tons of fill for the
Portavadie oil rig construction site which was destined to never see any
construction ending up as the deep water Portavadie Marina we find there today.

In 1968 the new
company of M.M. Brown & Co. of Greenock purchased the 38gt puffer ss Glencloy, which had been upgraded
to an oil burner in 1955, from A & G Hamilton Ltd. of Brodic. Operated by
Alexander McNeil Co. and renamed the Glenholm, within a year, whilst en
route to Dunoon with a cargo, when her boiler failed causing her to lose power
and run ashore at Cove near the entrance to Loch Long. She was a total loss and
the last steam puffer ever to regularly trade.
The Norstar
was one of the dredgers used to dredge material in the River Kip to make an
entrance for what is now the Kip Marina which opened in 1973. Much of the sand
used in the construction of the Inverkip power station came from this project
and included opening out the small WW2 basin at the mouth of the Kip to form
the marina.
It is interesting
to note that whilst the Crown Commissioners in Scotland normally own the seabed, in the case of
the Kip Marina project the Argdowan Estate claimed ownership of the seabed “as far below low water as a man on horseback could throw a lance”. This
being a right granted by royal charter in the time of Robert the Bruce. This
ancient right was not uncommon and was taken advantage of when the Alexander
McNeil Company / M.M. Brown & Co. purchased Loch Ridden Farm giving them dredging rights for the
adjacent seabed. The company undertook a number of other steps to establish a
sustainable business in the area, including opening a yard at Queen’s Dock in Glasgow . The move lasted less than a year and was
closed after efforts to make the plant profitable were thwarted by the demands
of the local trade union. This left the company with their Victoria Harbour yard in Greenock which they had moved to several years
before when their Albert Harbour yard was filled in to construct the
Greenock Container Terminal. Eventually Holm Sand decided that operating from Victoria Harbour was too far from their customers and ran
down the business.
Sand dredging in
the Clyde ended in the 1970’s?
