Re: Need Opinion: Chart plotter, north up or course up?

One more vote for north up when planning, course up when underway. And I'm an old guy...started with paper charts only and compass, then went through the loran phase, then the GPS with just numbers, then chart plotters and separate radar, then integrated systems. Yea, walked to school both ways in the snow without boots too.

If you have vector charts, the course up label's turn right side up. If you have a good radar overlay, everything is on one neat picture, and I find the latest navigation gear from the big vendors tends to do a course up display that is smooth even in rough conditions. You need good heading information for this to work right (or your radar and chart overlay won't line up).

All that said, we keep the paper chart open on the nav table and keep a position log on long passages, for when everything breaks onboard and the satellites fall from the sky during the zombie apocalypse We can still plot, DR, etc., just incase.
