I came across a 1836 Admiralty chart of the Thames Sea Reach, scanned it in sections, stitched together and added it to my mapping and navigation software I used when sailing.
I calibrated the map by using 9 landmarks like churches and such which have not changed position over the years.
I then traced around the coastline of the modern map and overlaid the breadcrumb trail onto the 1836 chart.
Although there had been a lot of movement in the sandbanks, as there always is from year to year, the outline of the coast was incredibly accurate.
My hat goes of to those talented navigators of yesteryear who charted the waters and land across the UK..
