New OpenCPN user here. I used Nobeltec
8 for many years. But, now I need to upgrade my WinXP to Win7 and found that Nobeltec
will not just copy over (and is no longer supported). So, I found OpenCPN and am impressed so far.
I have to admit that I'm not a boat owner. Instead, I'm an engineer
that performs testing/research involving boats and ships. I use these navigation
tools to prepare and monitor
experiments. I need to request a boat or ship to follow a prescribed route
. I'll telemeter the ship's GPS
to my shore station in order to monitor
their position (use OpenCPN to display telemetered GPS).
So far, I only see one missing feature for my purposes. I bring this request up because I suspect that other folks might also make use of this feature:
I would like to be able to display range rings associated with a waypoint. Just like the range rings associated with the own-boat, I would like to define the number of rings and the radius spacing.
I use this often when I want to define equal length tracks centered on a specific waypoint (for my purposes, I need to see the boat at different angles... but I don't want the boat drifting out of my field of view). The waypoint is my primary measurement point. I place start/end waypoints along the range rings to show the captain
the desired routes (look angles). An inner range ring is good for slow speeds and outer rings work for higher speeds.
I hope this makes sense... thanks
