North Up or Course Up

[ QUOTE ]
Can't see that. You'll be scanning the screen to find out where your boat is.

Jeeze! You have to scan the screen to see obstacles, rocks, the coast, the port you're headed to, etc. If you choose not to "find ship" and so leave the chart fixed and let the boat run across it, you have to scan the chart to find the ship. It's not exactly difficult, and probably takes even my creaky old brain only about 0.01 seconds.

So what do you do? Do you only look at one part of your screen, namely the postage stamp size icon for your boat, and not bother scanning the whole picture? /forums/images/graemlins/grin.gif
 
Good thread BJ /forums/images/graemlins/smile.gif

Here's a shot from SV en-route IoM to Anglesea...

Funny thing - I read the charts N up /forums/images/graemlins/shocked.gif

Simple eh? /forums/images/graemlins/grin.gif
 
I'd HATE to have that display SV. It took me a couple of seconds to figure out that the blob at the top was really anglesey, becuase to my simple mind it was in the wrong place! But each to their own :-)

Didn't know you had a s/thruster, you big girl /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif
 
Here's another one to show you where you have been /forums/images/graemlins/grin.gif...

Actually, very handy for keeping an eye on MrsSV when working on the stern line. She cant hear me with the engines running so we use hand signals /forums/images/graemlins/wink.gif

And you cant have bow & stern thrusters without this thingy...

Also very handy when letting SV drtift into our very tight fuel berth - just steer the arse in first followed by the pointy bit /forums/images/graemlins/grin.gif
 
When I looked at SV's picture (of the plotter) I thought "that looks all wrong".

Then I thought. "Hang on, I use course up, too"

Then the penny dropped: I tend to use course up for pilotage where I have the plotter, the radar and the mk 1 eyeball seeing the same view in the same orientation.

On passage, I tend to switch the plotter to north up so that its orientation is the same as the paper chart. I leave the radar set to course up though.

Seems to work for me.
 
SV's pic looked totally normal to me. It's only the same as turning an atlas so your destination is in front of you. A better pic though would be one with several waypoints on it where in relative mode you can instantly see where the waypoints are so you can look straight up and pin them with the mark one eyeball.

North up. Course up is for girlies with no sense of spatial awareness

I'm with Deleted User on this. North up for the win.
 
I switch between NU and CU. I use NU during passages, and CU for pilotage when approaching a mooring or harbour. What ever suits folks is best. I have no problem with North up as it's the same as using paper charts, but Course/Head up suits folks with a less than perfect sense of direction (ie spatial relations appt, and I'm not talking about extra terrestial in-laws)

[/ QUOTE ]Blimey, with engines at or just above idle, as they normally are when mooring?!? /forums/images/graemlins/shocked.gif
If so, I'd suggest to check either engines or hearing....
 
Sorry, can you repeat that please /forums/images/graemlins/grin.gif

The exhaust outlet is about 2 ft from the stern cleat so mrsSV cannot hear me unless I shout. If I shout then she shouts back and then all hell breaks loose /forums/images/graemlins/grin.gif
 
Understood. I don't dare thinking about how the hand signaling can develop when things go wrong... /forums/images/graemlins/grin.gif
 
Yup, I'm also a big fan of consistency onboard.
But radar and plotter serve very different purposes: collision avoidance and storm monitoring the first, route control the latter.
And I think that respectively head and north up are the most effective choices given these purposes - though what has been said re. personal preferences remains valid of course.
Overlay is actually not very useful imho, but of course if and when used it requires the same orientation, hence my original question.
 
I'm north up too.

I use split screen anyway, top half chart - north up - and the bottom half rolling road, which is, by its very nature, course up.

I use split screen because unlike some "bespoke" designs I have seen in MBY recently I only have room for one screen. /forums/images/graemlins/smile.gif
 
Plotter ... 15" Laptop ... North Up always, and display is further away than my 12" Radar display, which is mostly course up and being referred to more often when underway.

Nav instruments used onboard, in my subjective priority, are;

Eyeball MK1
Passage plan & Almanc (printed or intended)
Compass
Echo Sounder
Chart, Compass, Pen, Paralell Rulers
Watch
Radar
GPS
Chart Plotter (with seperate GPS feed)
