I used to draw on by hand 99% of my chart corrections from NTM using a Rotring Isograph pen in the 70's and early 80's. Probably sounds quite nerdy - but I used to get a great deal of enjoyment from doing those 1000's of chart corrections - kind of therapeutic working in a quite charthouse.
The booklet of corrections and the chart templates used to arrive onboard by mail back then, looking at the Admiralty Maritime Data Solution (UKHO) website today, I see that the weekly notices are now downloadable and that paper charts are due to be withdrawn from production from 2026.
