  • RIP psail - Joao Malafaia
    Board » General Discussion



    Words rarely fail me, but today I am lost. A whatsapp from my Sailonline buddy Joao Malafaia came in towards the end of the morning. Strangely, it was in Portuguese. It looked like it might be an invitation to a festive occasion in Lisboa or something. Perhaps my name had ended up on the mailing list. I wasn't going to be able to make that, but I thought I better run the message through Google Translate. There was a word that was bothering me: 'falecimento'. Had Joao gone broke? As I typed in the words and Google translated, horror gripped my heart. Joao, SOL navigator of psail, had died. The message was from his son, Miguel. There was a phone number and so I called Miguel.
    Joao had suffered a heart attack. Miguel and Joao's father, who were there when it happened, were not able to help or get help in time. Out of the blue, blackest swan! Joao will never sail online or on the sea again. My great friend, who changed his password to 'Big Hug' (Grande Abraço), his standard email sign-off, so that it was easiest for me to remember it, if I was going to do a spell of boat-sitting for him. Joao, who I first met sailing on VR with sailonline.org boldly written along the side of his hull! Joao, SOL's greatest source of new and exciting polars, and creator of the ever so challenging 40ft Series. But also Joao, the precision geotechnical engineer, proprietor of Pertis Engenheiros Consultores Lda, and Joao, who sailed with me across the seas of the Mediterranean, and above all gentle, generous, adventurous, and sometimes grumpy, stubborn Joao. Fair winds, Joao. I am quietly heartbroken, and all of SOL will miss you.

  • Gribs
    Board » Technical Discussion
    When the Sardinia Cup opened yesterday, some racers noted that the wrf gribs outside the racing area and out to the weather system looked odd, and they do, and they always have done. As we do not sail there and the software that modulates the synoptic forecasts to generate local so-called 'meso' effects has to do a lot of 'crunching', the wrf gribs that are fed into SOL only cover the racing area. The rest of the weather that you see on SOL or that you download from SOL via brainaid or AGL is generated by the SOL bilinear interpolator. Since between the race area boundary and the weather boundary there is only one piece of data available for interpolation, that being the data at the race area boundary, the result of this interpolation is constant wind out to the weather system boundary and this looks odd especially if the weather system boundary is a long way 'out'. Those of you mathematically-minded may well wonder why does the weather not reduce linearly to 0 at the edge, then. Well, because that's not how the algorithm is written.
    Some of you may also wonder why we show weather out beyond the race area at all. The reason for that is that the predictor line(s) pointing out from your bow will go haywire if it/they run(s) out of wind in less than six hours ahead. So we have to have wind six hours ahead at your boat's Vmax at right angles out from the boundary.
    As said, it has always been thus, from the very first time we used wrf for the Boston to Newport and then for such iconic SOL perennials like Pacific North West and The Vineyard and all our Sprints including those in 60kn DN's requiring gribs extending across vast areas of frozen forests, prairies, tundras and the like.

    After a month going nowhere too fast in the GGR, Tamalone was moved to compose...

    This is the race that never ends,
    It just goes on and on, my friends.
    Some started sailing it not knowing what it was, And they'll continue sailing it, forever just because....

    Board » Sailonline Yacht Club
    I DECLARE I will sail SOTP/NOA (No Outside Assistance). I will not:
    use routers (of any make or type),
    use spreadsheets or even calculators,
    use other external aids made avaIlable to our community by SOLers such as BrainAid, AGage, Kipper1258 and kroppyer.
    I may use:
    a sliderule, a straight edge and prints of the SOL polar diagram (but probably not).
    THIS WILL BE A NEW EXPERIENCE FOR ME, BUT I DO NOT EQUATE IT TO SWITCHING ON MY BRAIN.

    OK, so that was Leg-I x3 times.

  • Round the World where it is wide
    Board » Sailonline Race Committee » Race proposals
    SRC probably has enough race proposals to last a lifetime, but, if we agree that long distance ocean races are the lifeblood of SOL, then perhaps we could do with some more variety in this category.

    I am no fan of Google Earth as a route-creating tool, but, when I came across GEPath1_4_6.exe to make life easier, it motivated me enough to want to convert my ideas into .kml files.

    There are a number of them. I'll deal with the first one now.

    For a long time, I have felt that these races down the Atlantic, around that southern island and back up are badly described as "round-the-world". Round Antarctic seems more accurate with a leg to get there and another to get home again (if you're French).

    A proper round-the-world race surely should attempt to circumnavigate the globe there where it is wide, so either a round hugging equatorial latitudes, or a spin hugging one or other meridian from North to South and another back from South to North, or the other way around.

    The stumbling block of course is that made-up races are not 'real' races, but doess that really matter?

    Also I am conscious of a certain distaste for in-course marks among sections of our ocean racing community, so my first proposal, a race in six legs chasing the setting sun, has none. This results in some finish lines benig far from square to the line of approach from final coastal obstacles, but with legs of on average around 3500nm that hardly matters, and, a plus point, it makes life easy for the course planner as well.

    Here then I give you the ESRW, the Equatorial SOL Round-The-World Race.

    ESRW-I - Haifa to Sao Vicente - 3400nm
    ESRW-II - Sao Vicente to Colon - 3200nm
    ESRW-III - Panama to Honolulu - 4600nm
    ESRW-IV - Honolulu to Port Noumea - 3350nm
    ESRW-V - Port Noumea to Singapore - 3950nm
    ESRW-VI - Singapore to Kuwait - 3600nm

    Some highlights.
    The race starts off the coast that is home to the world's first monotheistic religion and finishes off a coast where the world's most recent monotheistic religion is the dominant faith.
    I considered Port Said at the entrance to the Suez Canal as the final destination, but felt that we would have more fun sailing up the Persain Gulf than dito up the Red Sea. As a result, the circumnavigation is slightly less complete.
    The furthest South of the equator our course takes us Port Noumea on New Caledonia.
    The furthest North is Haifa, our departure point.
    Three of our ports of call lie within 10 degrees either side of the Equator.
    Colon and Panama, either side of the Canal (we will not sail the canal), and Singapore.

    Pick a fast boat. I suspect the wind will be all over the place, so a Mono 90 or a Maxi 100 perhaps, for both up- and downwind performance.

    PS this file attaching is confusing me, so this may go awry for now.
