    All at your leisure Julian Your thoughts are appreciated but we recognize they're offered gratuitously and business takes priority. Time is not of the essence, even if we might occasionally make sure we're not completely forgotten.

    US Portsmouth Yardstick Change?

    Here's what we use in Australia, including a description of methodology. https://www.sailingresources.org.au/class-assoc/yardsticks-chb-handicap/ Note the yardsticks are listed as reliable, probable and tentative. Frankly, it all works pretty well at any club I've sailed at. Not prefect, but good enough. And if you must win silver trophies, you can always pick a class that's maybe a bit favourably rated. But in my experience, people mainly sail the boats they like to sail.

    US Portsmouth Yardstick Change?

    We race the equivalent of Portsmouth all the time in Australia at many clubs (through VYC Ratings). We don't have wind factors and happily accept that many of the ratings are tentative because of inadequate statistics. On a river, our fleet is divided into Gennaker/skiff type boats, Monohulls, Cats and trailerable yachts (with about 10 boats per division in a small country town). Gennaker boats and monohulls are separated only because they prefer different course layouts. It all works with minimal complaints and fleets that are almost too big for the river we have. Yes, if you want to win, you make sure you have a class that has a favourable rating; but really, as we say in Australia, we're not sailing for sheep stations. Most people sail what they like sailing. And some classes have even asked for their ratings to be made less favourable because it might have been seen as reflecting badly on the speed of the class. The only serious problems I've seen are where you get foiling boats and try and put them in with non foilers. They are just too different and the outcome way too predicated on conditions for the racing to be as fun. They too need a separate class.

    Well, while waiting for Julian's additional words of wisdom and continuing to contemplate how and whether I might get a 49erFX as an additional training boat, one of my group - showing the enthusiasm and resourcefulness that has typified the women coming through the training - has got herself a training session skippering on an 18ft skiff. It just shows why I'm so proud of them all and wanting to help take them further in their sailing.

    More to the point, there were 4 known cases at the BLM rally (diagnosed soon enough after to not have caught it there, but very likely to have carried it there). The real question is how many they spread it too which are contained in the spike. I wonder if it's a question they're asking the now infected. Doubt it.

    GoPro camera.

    I've used both a handheld mount and a cycle bar mount attached to a short pole, in both cases taping them to the end of the boom with gaffer tape. And I always tie them to the end of the boom to

  9. Hi Julian Just to be clear, I would read you as saying they should use an XS rig, not a full one. Is that right?

    We seemed to have moved from a long term fix of social housing to dealing with a unit block under quarantine. Different issues.

    Too late That happened already in Sydney and went down very poorly. Mind you in was a building in the center of Sydney overlooking the harbour

    The practical problem is that when this is done the community itself (and their supporters) create an up roar about their dislocation. Cost effective location means far outskirts. You can't have both

    They have individual ventilation (called windows) and aircon. Not a central one. They do have shared laundrys, but I assume these are closed. Shared lifts are a problem if people were allowed out of their units and I suspect part of the reason for the tightness of the lockdowns,

    Thanks for this first installment Julian. I recognize some of it as being an elaboration of what was in one of your father's/ your books (they are lent out at the moment so I can't check) and answers some of the questions I had after reading that; especially the calculation of (I think it was) Sail Carrying Power (SCP) the formula of which wasn't entirely clear from the book - although the factors that went into it could be inferred. Just to confirm my interpretations (and maybe help others wrestling with the formulas and concepts), my understanding is BS is Boat speed AWS is Apparent wind speed While I can now see how ARM is measured, do the initials stand for anything or is the word 'arm' itself the concept (a bit like 'righting arm') "Yawl" is what I might have thought of as side slip or leeway (expressed as a degree off course)? I'm not quite understanding the "half of that doing anything" concept in relation to the centerboard, combined with the suggestion that only the 300 to 400 mm under the keel is the bit doing anything. This is a new concept to me; the suggestion that the bottom section of the board is ineffective? I presume the 5 degree canter to windward at 22 degree apparent wind is the rake of the mast? COD on the centerboard is Center of Drag? [This is definitely a question; not really a concept I've struggled with before - if that's what it is] But there's some really interesting stuff in what you've written that goes well beyond what I've managed to absorb from previous writings (mainly your family's) I'm really looking forward to the next installment. Much as I asked your father to do all those years ago, If I was to take the sum of your writings and try and break it down and express it in a way that could be presented as a lecture to reasonably intelligent people, might you be willing to review it?
