First let me say that I love OpenCPN
and I full appreciate the thousands and thousands of hours that have gone into creating and enhancing this fabulous tool.
But Wow, I am totally unable to get this weather routing thing to work. About once a year I try it and get so frustrated that I give up. I am very savvy with OpenCPN
, pretty computer savvy, and somewhat "weather routing" savvy. I can usually muddle through without reading the directions and figure things out, when others can't. A year ago, when I was frustrated, I posted on the SCCA Facebook page "does anyone know how to use the weather routing in OpenCPN?" I was surprised that I go NO RESPONSES. That tells you something.
So it was with great excitement that I noticed and updated plugin on the plugins page. We are tracking friends on a tough upwind trip in light air, and trying to give them some routing advice. Plus we regularly do short ocean passages in the western pacific, and I'm looking forward to have an onboard replacement to the routing I used to do with Maxsea
So I've got 4.4.0 and the latest Weather Routing plugin I downloaded from the Plugins page 2 days ago (1.10.x). I'm on Windows 10.
It was with the usual confusion that I tried to figure out how to start from scratch, with a boat
configuration (this is where I've always gotten hung up before).
But I muddled around and used (I think) the default boat
.xml and loaded a polar for first a Contessa 33 and then (later, when that didn't seem to be working), a Crealock
I figured out how the start and end thing works (and do agree that there's a bug in deleting a routing point as reported by the OP a few pages back).
Then I clicked Compute.
Twice I actually got a routing, which was a straight line (straight upwind) at about 5-6 knots. Note: That ain't happening under our prevailing conditions, especially not with a 33 or 34 ft boat, unless we're motoring (and even then not!). Is there a motoring provision??? I can't find it (like "motor if speed drops below X knots, and motor
at Y knots).
The rest of the time, I click "compute" and nothing happens... no error, no progress window, nothing.
Even when I did get a routing, I got none of the "isochrons" or anything displayed on the screen
(NOTHING like the screen
shot RGleason posted recently on this thread)... almost nothing happened until I clicked Export on the screen, and then the plot showed up as a route on my chart. I can't get it to do anything now, so I can't even show you that.
Some screen shots are attached, and the WeatherRoutingConfig file is too large to attach as a txt file, so here it is:
<?xml version="1.0" encoding="utf-8" ?>

If you can point me in the right direction, I'd appreciate it. I'd love to get this working. It's my favorite thing to do on passage
(play with routings). Meanwhile, I'm using Fastseas.com to route for my friends... 5 minutes from never using it before and I got a believable routing out. Pretty impressive.
