22. Chart of Plymouth Harbour by Copper Plate Printing Office
22. Title: Chart of the Harbour of Plymouth Taken 1817. (Title above border centrally, Taken 1817 below this just inside border.)
Date: 1817[1].
Size: 480 x 360 mm.
Signature(s): None.
Comments: The chart covers an area from White Sand Bay and Ram Head (Ad) to
the Mew Stone (Ed) and the course of the river as far as Tor Point (Bb) and
Keyham Lake. It shows depths in the Sound as well as the Breakwater but lacks a
bottom border. Tor House has been included beside the title and above the top
border (see illustration below). Magnetic north is included in the compass rose.
On the right is a sketch A of a dry dock with dimensions: Breadth
60 Ft, Depth 18 Ft and Length 160 Feet. This is explained in the Reference (Ea)
as a dry dock at Tanchapel (sic); this should be Turnchapel (see illustration below). John Parker, also
known as the 1st Earl of Morley, was the landowner at Turnchapel, and
he improved the wharves at Turnchapel, an important site of repairs to His
Majesty´s Navy, with a wet dock (c.1898) and a dry dock in 1804. In 1812 it saw
the launch of the Clarence, a 74-gun ship-of-the-line.
The approach using
Tor House is clearly explained: Tor-House and Black spot in a centre of a
White Patch on the Garrison Wall is the leading Mark through Sedley´s Channel.
In Cooke´s plans of Plymouth Dock (19 and 20) he had omitted all
coastal features, but in this chart, we have a suggestion of coastal shading. The
mud flats to the west are clearly shown, not dissimilar to those of his Falmouth
chart (see next entry, 23).
Mud flats in the west and Tor House next to title.
