Swinging a compass normally requires a known heading and steering the boat on that,to see what the ships main compass tells you,then either adjust it or make a note of the heading for navigational works and adjustment on your paper chart work.
In our case this was not done in that method,we had an electronic compass that needed a 360 turn,it will then program its memory and know its headings,check the two circles on the plotter (enlarge with a left click on the picture)
Crew member Hamish gets some hands on compass instruction from his grandad Notty.
