Default C-Up/N-Up-Head-Up?

What does everyone use?


I just installed the 4.29 software for my Raymarine E120s and I cant remember what setting I had it on.

I was curious as to what others here used.


Should the radar screen and the plotter screen be on the same N-up/C-Up/H-Up setting?

Thanks

As a legacy from my Navy background, I prefer North up.

I've always used course up as a general practice, except for drift fishing where I found north up to give me a better perspective to get repetetive drifts over the same structure.

I prefer N up, especially when in strange places. When in home water, I usually use C up. I find N up orients me more quickly, but I think that is just different from person to person.

If you like using Radar overlay on the electronic chart, you will want both the radar and the chart sync'd to the same orientation. Otherwise, it is more of a personal preference.

Likewise, it sounds as if you may have multiple displays. At night, things can become somewhat confusing with the radar on display A set to 'Heads up' (best for collision avoidance) and the chart on display B set to, for example, 'North up'. In this case, stationary targets, such as an island shore line, or a channel marker, will not Jive between screens.

I, personally, prefer 'Heads up' for radar and 'Course up' for electronic chart. If I am attempting to use the radar for True navigation in restricted visibility (as opposed to simple collision avoidance), I will view radar in North up, to compare to a paper chart, for short periods of time, then back to 'Heads up' for collision avoidance.

At times, when the radar is left on standby, I may set the electronic chart to 'North up'... but I find I do not do that all too often. Old timers tend to prefer 'North up' as it is oriented much like a paper chart... what they are used to working with....

It is all preference, hence why the manufacturer gives the Captain the option.

The other preference for N up on a chartplotter, at least on a lot of sets, is it tends to keep the chart much steadier & easier to read. However, Heading up tends to be much more natural for radars in order to keep track of potentially dangerous target/ returns at bearings instinctly relative to the bow and &, as Jim notes above, overlays must be synched in the same mode as the underlying chart or vice versa.

I always use North Up for everything, just less confusing and I always know what it's set on. JMHO

Yes, North up for drift fishing. That way I know which way to turn the boat to re-trace my bread crumb trail.

How about "use whatever you want"??

NEITHER is better. Both are correct If you get from point A to point B without hitting bottom or any marker / buoy, does it really matter how your plotter is oriented???

I prefer course up while running & north up while drifting over a wreck/structure so I can get back on it in a hurry.

I learned navigation as a pilot, with everything relative to the airplane, so its heading up for me. I'll run into something if I have to do a plotting board solution! If I ever have to lead a formation of vessels someplace tricky, somebody else had a very baaaaad day.
