Dive Site Chartlets

This page is a permanent "work-in-progress". As I get new data, the diving chartlets will be updated.

Hand-drawn maps and charts done by collecting data from many dives with me taking notes and pictures underwater while my buddy drags around an SMB with a GPS. Where indicated, the UKHO sounding data are taken from the Admiralty Maritime Data Portal here https://www.admiralty.co.uk/ under the Open Government License.
