    Viva Philippe

    Good morning.

    Thank you for info.
    Yes, it works as the former "B" command.

    In general routing software generates an astronomical number of Displacement vectors (module unit is nm) where on top of their extremities it draws the so called Isochrones curves.

    To have a slight idea on the numbers involved on this calculations and using the qT process/settings we have:

    1 - 180 degrees of scanning angle;
    2 - 3 degrees of angular step;
    3 - 60 Displacement vectors in the first calculated minute;
    4 - 60 + 60 x 60 = 3.660 Displacement vectors on the second calculated minute;
    5 - 60 + 3.600 + 60 x 60 x 60 = 219.660 Displacement vectors on the third calculated minute and,
    6 - so on, resumed in the following formula:

    S (60 ^m),

    where:

    "S" represents Summation starting in i = 1, 2, 3, ...., m;
    "m" is minutes (integer number),
    “^” is the power symbol.

    As a sado-maso exercise try to use (only) the WX tool just to find out the best route for the first two minutes of race.

    P.S.: You stil have time to make it for the next race in 2,5 days. Uppps.... maybe not because by then the the WF will be other.

    God afternoon all.

    Since one of the last qT revisions the "B" command disappeared.

    Pity, because it was very useful.
    Hope it can be implemented again.

    Viva John and all.

    Good morning.

    In relation to your question I think the right answer is "no".

    Anyhow, using the so called "WX Inspector" in this race and accordingly to its spirit , at least to me, is totally pacific.

    You should always know your boat Performance Targets, using or not anykind of weather routing software.

  • TP52 Series.
    Board » Sailonline Race Committee » Races
    Good afternoon SRC and all.

    For now, my suggestion isn't for a new race/s but, to use already established SOL ones to make a OD Series, using the TP52 boat.

    Off course, without prejudice for making new courses for this particular Series.

    What do you think?

    João/psail

    P.S.: I salute SRC decision for sailing the Van Isle 2018 race with this boat. Excellent idea.

    So it's "retro".
    Ok.

    I'll sail it like the first time I SOLed along.

    Good morning all.

    Routings made with the SOL GRIB and a WRF GRIB.

    The second one is faster by almost 2 hrs, keeping the path closer to the coast.

  • 40 Series - Ratings
    Board » Sailonline Race Committee » Races
    Good morning all.

    I open a new thread related with boats "Ratings" to all who may be concerned, namely for the SOL 40 Series Scoring process.

    In first place I recommend all to have a reading on the following link:

    http://www.orc.org/index.asp?id=31,

    from ORC.

    Under ORC Scoring program the boats "Ratings" can be achieved in #4 different ways.

    As an example, for the PCS method (Performance Curve Scoring) there's already available (free) Software for calculating the "implied wind" and Corrected Times using a Performance Curve - link:

    http://data.orc.org/tools.php?c=pcs.

    If we gather some SOLers with a minimal expertise on handling this issue, I'm sure we can make it work for the 2019 40 Series.

    The word to You.

Sailonline’s 11th Birthday Balloon Race
Eleven is an odd number, numerically as well as numerologically. Boastful and extravagant, adding one to the complete and perfect ten, 11/11 is also the day and month WW1 ended, so a number well worth celebrating after all. Whimsically then, in honour of SOL’s 11th birthday, your SRC gives you a re-run of 2013’s Trans-Atlantic Balloon Race. This race to be the first to ‘land’ your balloon in the sea off the Cliffs of Moher is not for the faint-hearted, nor for the serious-minded. Unusually, SOL’s balloon, polarized by past SOLmaster 76Trombones, will not ‘sail’ over land and will actually ‘sail’ in other directions other than straight downwind, although beyond a ‘beam reach’ it will not go. Good luck!!

Golden Globe Race 2018 - Leg 2 Storm Bay to Les-Sables d'Olonne
Welcome to Leg 2 of Sailonline's virtual version of the 2018 Golden Globe Race. After a brief respite in Storm Bay, Tasmania, of a minimum of 90 minutes after arrival, we are now racing across the Pacific, round Cape Horn and home to Les-Sables d'Olonne.
DO NOT START TOO EARLY
If you raced Leg 1 then you MUST wait 90 minutes before starting this leg. The penalty for starting Leg 2 before finishing Leg 1 is NO RANKING. The penalty for starting Leg 2 within 90 minutes of finishing Leg 1 is 5x the time you started too early.

Golden Globe Race - Leg 1 to Storm Bay
Welcome, all, to the 2018 Golden Globe Race and Sailonline’s virtual version of this iconic 50th anniversary rerun of 1968’s first ever non-stop single-handed round-the-world race in yachts and with technology in keeping with that historic time.
To reflect the challenge being undertaken by the real racers, as announced previously, SOL invites all who feel so inclined to add their boat name to the post in FORUM declaring you will race by the proverbial "Seat Of The Pants" (SOTP) with no outside assistance from routing software or other external aids, BEFORE THE STARTING GUN IS FIRED.
To simulate the real race which features a 90 minute minimum stopover in Storm Bay, SOL’s online version has been divided into two legs. This first leg then is from Les Sables-d’Olonne to Storm Bay. When the leaders approach Storm Bay, Leg 2 from thence back to Les Sables via Cape Horn, will open. YOU MAY NOT START LEG 2 UNTIL AT LEAST 90 MINUTES AFTER FINISHING LEG 1. The penalty for starting Leg 2 before finishing Leg 1 is NO RANKING. The penalty for starting Leg 2 within 90 minutes of finishing Leg 1 is 5x the time you started too early.
DO NOT START TOO EARLY!
Fair winds and good luck!!
