That's what I understood.
And for my simple mind, keeping everything on the chart as True keeps life simple. It tells me where I am and where I want to get to.
All the calculations that tell me which way to point the boat to follow that line on the chart are done by my instruments. (which because of weather
information, rarely tell me to follow the rhumb line in any case).
But, as I'm often informed on this forum, one day my instruments will be struck by lightning
and so I'd have to revert to pencil and paper. In this case what would go on the chart?
- yes - tells me where I want to go
- no - would just confuse me and doesn't give me any additional information above True - which I already have
- no - Is of no value to me - it doesn't tell me where I am or which way to point the boat
- possibly - because this tells me which way to point the boat. But, more likely, I'd scribble out the calcs for TVMDC and Leeway in the log or something and then write the heading on the compass binacle.
What is on the chart is true
Where I need to point the boat (allowing for variation, deviation and leeway) is beside the compass.
