Tips from the Community

I’d like to encourage a bit more community sharing on this blog, so I would invite any experienced router users, regardless of which one, to post some tips on using Bluewater or just routing for SOL in general as comments on this page.

If we get enough of them I will compile them into a single pdf for download.

    In my oppinion, and with the caveat that I may be wrong:

    BWR polars are “unusual” i.e. their second and second to last TWA entries are max VMG. The logic behind this is that one never sails above VMG on a tack or below on a gybe. (unless downwind in an uprising when TWS is 7.8 kn – but I digress).

    This philosophy assumes intelligence on board the boat. In SOL, we may have the finest helmsmen and sailtrimmers onboard, but their accumulated brain power is the size of a dead pea.

    It is up to us, at the keyboard, to analyse the CC’s set by BWR. With the wind astern, or ahead, BWR will happily set a CC on “the wrong” side of VMG.

    appologies to Jeff if the above is incorrect.

      True about the polar format for BWR (which isnt an issue if you use my polar converter 😉 ) – BUT if you never sail above vmg you are missing out on some gains… There are times it is the right thing to do

    Eh – this is not a comment! I just forgot to tick the “Notify me” box when I posted my comment.

    – experiment with your settings for time , range and grid. within a race and try to analyze the different results.
    – never take a suggested route for granted, always try to figure out why it sends you somewhere if it differs from your own general opinion
    – try to use minimized polars , saves a lot on calculation time . ( see Schakels blog SOL’d for a detailed report ) and outcome is still good
    – Use BWR for general route guidance but do the finetuning by hand

    Amending BWR pref file.

    Actual works pref-file can be found here : windows 7 -AppData-Roaming-bluewater-bluewater(pref file )
    Open the file in wordpad.

    To be safe rename your original file to bluewaterold. That way you always have a correct file around should you mess up.

    All preferences can now be amended manualy.
    some examples:
    inspolar : polar file that is used in the instrument manager.
    initroute: route file that will be opened upon startup of BWR
    initpolar: polar file that will be opened upon startup of BWR
    NMEA1 : NMEA port for instance to connect to brainaid proxy

    Save file after amending as bluewater
    Start bluewater and your prefs wil now be loaded.
