Reflections of the H.M. Frigate Unicorn
H.M.
Frigate Unicorn was one of four vessels built in Chatham Naval
Dockyard under an Admiralty Order issued in 1817. By 1824 when she
was commissioned the Neoploanic threat was over. In consequence she
was moored from the Portsmouth roads and used as a munitions hulk.
The ship during construction was sheathed in copper
plating attached to the timber sides to protect her again marine
beetle, which are found in tropical waters. This was necessary since
the ship was scheduled to join the fleet operating in tropical
waters. This form of protection is largely responsible for the long
levity of the ship to the extent that her sister ships have long gone,
and she is now the oldest timber built warship in the world, still
afloat.
Late 1873 the ship was brought to Dundee and birthed in
what was then the Earl Grey Dock, to function as the training ship for
the Royal Naval Volunteer Reserve (RNVR).
The RNVR consisted of shore based personnel of all
walks of live, who had a common interest which was the defence of the
Realm and a love of the sea. Their training covered all aspects of
naval training. Perhaps, the signal greatest tragedy and there were
many in the First World War, was the fact, that the government at that
time, drafted all RNVR personnel to the trenches in France. Their
training was not in any way compatible with that of infantry warfare.
The result was obvious --- very few survived.
After the war, an Act of Parliament was passed to the
effect that any volunteer of any of the three services would in the
event of a National Emergency would continue to function in his or her
choice of branch of the service.
This was implemented throughout the Second World War to
the extent that by the end of the Second World War 70% of naval
personnel were reservist the remaining 30% were professional Royal
Naval Personnel.
It should be noted that up to the conclusion of the
Second World War, there were in addition to RNVR personnel, Royal
Naval Reservists (RNR).
The RNR consisted of sea going merchant serviceman who
had an interest in naval warfare and had trained with the RNVR and the
RNR.
After W.W.II. a stream lining exercise was carried out
by their Lordships and the RNVR and RNR were amalgamated under the
one banner and became simply the RNR. The volunteers were men and
women from the ages from seventeen and a half, many of whom had
minimum education but wished to advance themselves and the RNR offered
them a golden opportunity. Indeed many of them transferred from the
RNR to the RN.
The range of activities and training offered covered
seamanship, navigation, marine and electrical engineering, medical,
communication, ship handling, small boat handling, gunnery,
accountancy/secretarial work.
Many obtained watch keeping certificates and
minesweeping command tickets. It is worthwhile noting that many of
these youngsters had never been exposed to religion prior to joining
the service. Included in the ships company, were padres representing
all major religions.
In 1892 the vessel was moved to the Graving Dock in
Dundee for an underwater inspection, which was found to be
satisfactory. On completion of the examination she return to the Earl
Grey Dock and remained there until late 1962, when she was moved again
to her new birth in Camperdown Dock. A year later she was moved yet
again to her present birth in Victoria Dock. These moves were
necessary because of the construction of the Tay Road Bridge and the
Earl Grey Dock had to be filled in to provide access to and from the
bridge.
It is of interest to appreciate the uniqueness of the
construction of the ship. Her vital statistics are: 150 feet long:
40ft beam: 15 foot draft; carrying in access of 17,000 feet of canvas
on three masts; her armament totalled 46 18lb cannons; the stem of
the ship was formed by laminating straight sections of timber rather
than being formed by natural bent trees. This concept was the
brainchild of the Admiralty Accountant, Samuel Peeps. Because the
ship was essentially a reconnaissance vessel it was a requirement that
she avoided direct conflict as much as possible. If that was
unavoidable and she was out gunned and being highly manoeuvrability
she could ram her adversary because reinforcing timbers extending to
the stem to the stern were built into the walls of the ship. These
reinforcing timbers were known as ramming stays, thus making the ship
highly resistant to structural damage.
The overseer of the four ships was a Sir Robert
Seppings, who introduced an additional innovation in the form of
wrought iron knees to reinforce the junction of the cross timbers to
that of the walls of the ship and additional wrought iron reinforcing
at the stem of the ship. The ships timbers are oak and the timbers
below the waterline are in excellent condition where as some of the
timbers above the waterline are in need of attention due to the
exposure to fresh water.
