Perhaps I just cant RTFM very well, so if this is the case, please point me to the relevant reading.


Is there a way to step through a grib file, while at the same time having a "boat" marker follow a route at a predetermined set boat speed as set in the route or perhaps even related to polars , in which case the boat speed will change according to the angle to the wind and the wind strength.

The idea is to be able to easier visualize the position of the boat at each point in the grib file.


Thanks guys

Would be nice to have an option to play a sound ("ding!") upon waypoint arrival in a route.

Bruce... you could do this in JavaScript.

Hint:
A script has access to the active waypoint GUID. Read it from time to time and when it changes, sound an alert.

I brought that up in 2015.... and created a flyspray entry (bug and feature tracker, aka cemetery of good ideas )

There also the weather-routing plugin was mentioned, which is a rather complex solution many users are struggling with. Weather-routing also does not solve simple what-ifs, like "if I slow down a bit, can I avoid the worst rain from that front). weather-routing uses wind/current and boat polars to calculate the fastest route to a destination.

But other inclement weather (rain, CAPE) is not considered. I currently do that type of planning in good old airmail2000, which does have that "set a course and speed" and plot the estimated boat position.

If you want, give that flyspray entry a "vote up".

Here's a JavaScript for you:

lastGuid = 0;
check();

function check(){
	activeGuid = OCPNgetActiveWaypointGUID();
	if ((activeGuid != lastGuid) && (lastGuid != 0)) OCPNsoundAlarm();
	lastGuid = activeGuid;
	onSeconds(check, 10);
	}

Hello OpenCPN developers,
(I ask to the manager of this forum to delete this post if it does not comply with the rules, in which case I would just ask if my message could be directed to the right persons)

I am writing this post here as I did not find an alternative way to contact the maintainers of the OpenCPN manual. In the OpenCPN manual there are references to Supplementary Hardware as multiplexers and converters. I design, build and sell multiplexers and I thought a reference to the products would help some OPenCPN users. Here is a link to what I am referring to: https://www.vela-navega.com/index.php/multiplexers

Kind Regards, Luis

My view..
This is a forum where all kinds of personal thoughts and experiences can be found. Members can post links to different brands of certain devices. If a reference is a result of good/bad personal experiences based on own use or a more or less veiled ad can be hard to detect. Your personal interest in your link is not hidden so I think most can read it as valuable related information.
I can say thanks for the info. Never heard of these devices and it looks good even if SeaTalk1 starting to be less common these day's? Pure N0183 multiplexing and filtering can be handled by OCPN itself in a very good manner. But a device for many serial to one USB can of course be valuable instead of several RS232-USB converters.

A manual/wiki referring to specific brands as example of devices suitable for the discussed purpose can of course be a veiled ad but that would soon be clear for most readers. It's up to each and everyone to judge what's read. As always.
A good example here of often mentioned brands are Acticense and YD for N2k conversion. There are not so much known alternatives so any further info in that matter, veiled ad or not, would be valuable I think.
