We need a Long Heading Line

I think the current handling, regarding line style, is fine. With an infinite heading line there is no need for a termination.

Perhaps COG should end in a triangle i.e. an EP (estimated position)? Well it does in British style (RYA) plotting anyway.

A square usually indicates a waypoint, but maybe you are using to indicate GPS derived EP?

In favour of a infinite heading line!

To overcome the loss of the course/speed vector, a mark should be added at a user defined distance (preferably either in miles or course/speed minutes). (It would be a shame to lose this practical current feature)

Suggestion to keep the vector and arrowhead but extend shaft with a different color maybe dashed line

Rob s idea would work too

Dashed line is already used for COG.

We are only talking about an infinite heading line here. COG remains configurable by the user in time, and hopefully distance.

There would be no loss of course / speed vector. The COG remains as it is.

Xiurong et al.:

in case you didn't see it -
length of heading predictor can now (latest beta 3.3.2107) be defined independently from the COG predictor.

Comments appreciated.

First observation, the heading predictor length number is "1" every time I start ocpn

second: I don't see the line (home pc test with bluetooth gps) I do get the COG line
edit>what was I thinking... a gps only gives a COG and no heading. But since my ship also only has a gps I even stronger want an infinite COG vector!

Third: I think I may have asked for the wrong line (not a native speaker...).
What I would like is an "infinite" COG line, after-all the COG is where the ship is going, the heading is only what you see in front of the bow... And on this infinite line I would like a marker that showes where I am in x minutes.
Because want to know if I'm sailing in the right direction to a far away point and I also want to know where I will be in 15 minutes. I can't imagine that I'm the only sailor who wants to know both without having to go to the settings menu.

xiurong made the intital request, and he asked for a long HEADING line that was very clear. I thing this is the appropriate long line for several reasons.

This is the best news since I aboard current vessel on 15-aug-2014 at Walvis Bay,Namibia.Thank you for this change made and say so many thanks to all the friends in this forum who helped me during my request!

I will post another 2 thread when I arrive at Las palmas or Immingham,UK.These 2 thread are about the COG and Heading line display style and,the COG arrow predictor length setting for OWN ship and AIS target.

Thank you again!
