Using BWR to Route the Shetland – Lerwick to Bergen Race

While testing the course file before making it available here on the 2012 Races page, I ran into a curious situation with the routing parameters. Basically, if you try to route the whole race as one route, you need to set grid size at about 2nm (and a corresponding max dist.). But because the first leg is […]

Using the VMG/C Calculator to Determine Favoured end of the Finish Line

So, now the tool is available, the next question is when and how to make use of it. (OK, perhaps that is 2 questions?) One usage that works all the time (by that I mean, for example, it is not always best to sail max VMC to the Mark) – is to determine which end […]

An accurate PC clock is very important when SOLing, especially for the SOTP SOLer setting DCs – but also for everyone. Read here for more on why this is so, and details of the tool.

Minor Course Change to SWR Leg4

The Sailonline World Race (VOR) Led 4 Course has been changed recently, adding a mark at the Northern tip of the Philippines. Although this shouldn’t really effect the fastest route, as it would likely have gone North of the Philippines anyway. All race and gpx files on the 2012 Races page now include this new waypoint. Tip for BWR […]

Update to Bluewater and the Timed Race Script

I have also updated the script for timed races to fix the issue of needing to close and reopen the Route Manager to see the routes named Run_# and the best route coloured […]

How to get your GPS data into Bluewater

To get this working, you will need to install NavMonPC and of course, download the NMEA Proxy for your boat in the race. NavMonPC is very useful by itself, but also offers the ability to resend any data it receives on a virtual com (serial) port – and Bluewater can only read data from com […]

New tool published – a Bluewater Script for Timed Races

As I said I would a few posts ago, I have now made available a tcl script for Bluewater to allow you to automatically compute multiple runs of a route, with a specified interval between start times. You load and use the script in the Bluewater console. Full details and a download link can be […]

Bluewater files for SOL races & Timed Races

I have ‘combined’ the content pointed to by the ‘bwr’ & ‘bwrX’ links on the race GPX page… Not really any point in linking to the gpx race file, and also a zip containing same file and the race polar for Bluewater… ? So now the ‘bwr’ link points to the zip file, as the […]

Added new race file for Bluewater users

I have added a fourth file available for download for each race from now on. I have added a link labelled ‘bwrX’ – to indicate it is for BWR, with ‘X’tra data. Basically, this is a Zip file that also includes a Bluewater optimised polar file as well as the race file. Each of these […]

2nd Bluewater Article Available

This one is just a pdf file, not a page here on this blog, and so doesn’t show in the list of pages on the right (hence this post to draw attention to it), but a download (or open in Browser) link is available on the BWR 101 page. It covers creating marks and course/route, […]
