After years plotting lines of position and courses at the chart table with parallel rules, dividers, etc., I decided to take the plunge into the 21st century and computer assisted navigation
(iSailor on a MAC). Being a 74 year old Luddite, I am having trouble understanding some basic concepts which are not clear to me from the documentation
: in particular, I cannot find where true or magnetic course lines and bearings are so indicated (something like CDMVT/TVMDC when done manually). I was hoping that one of you computer generation whiz kids
could point me in the right direction. I'd be much obliged.
