    New Aftmast Rig

    So are you going to keep out of spamming Cruiser Forum threads as you have been asked to?

    New Aftmast Rig

    I AM noting what Tom wrote. He wrote that he “agreed completely” with Mikko’s statement that "the mast is not just a drag-device but contributes significantly to the driving force of the sails…..the mast drive (is) 1,2 kgf (that's in the positive, forward direction for the mast as well. “ Look...

    New Aftmast Rig

    Here in the Sail Aerodynamics thread page 24, in reply a comment (post 358)” by the valued and expert Mikko Brummer who you so foully accuse of writing “BS”. In his post 359, Tom “agree(d) completely” with Mikko’s comments that "the mast is not just a drag-device but contributes significantly to...

    New Aftmast Rig

    When it comes to BS, Brian, you are the master at spreading it. For someone who has spent years fantasising about how great his rig will be but somehow can’t get his act together enough to even build a test rig to throw such accusations at someone who knows far more about the field than you do...

    A new level rating development class?

    The 1880s sailing canoes had a bunch of combined paddle/sail events where you had to switch modes depending on which leg of the course yo were on. The Brits even had short races where you had to portage your canoe in the 1880s; in fact I assume they are still quite common although over longer...

    A new level rating development class?

    It’s not a case of “at least now you have briefly thought on it” - I’ve seen the concept proposed before. It just that people never seem to actually really consider what is very likely to happen under such rules. The old time fishing boats like sandbaggers were often quite standardised - I was...

    A new level rating development class?

    It’s been proposed many times before. It’s not new or out of the box, it just doesn’t stand up to examination when seen in the light of experience with development classes and class development. When the quick fitting can only be done by giving equipment a short life, requiring pit crew or...

    A new level rating development class?

    It’s hard to see how new sailors seeing something like a 28 ft foiler with canting keel, wings and trapezes and costing $700k or more will say “I can do that”. They won’t be able to. The classes that are probably closest to that are the 12 Foot Skiffs, the Ultimes, and Formula 20 or C Class...

    A new level rating development class?

    You can have overhangs in a box rule - the Micro Cup class has moderate bow rake because it mandates it. Banning scow bows is arguably a very good idea because they are effectively a way of just fitting a bigger and more expensive boat into a set overall length rule. Once one allows bigger...

    Why do many designs fail to form products?

    This was marketed in the ‘80s. Either the magazine I used to work for or another one did trials and found that in any wind, the balloon would just blow down to water level. The magazine did some actual testing of rafts, MOB techniques etc and I think I have a vague memory of watching this idea...

    Help me identify the make of this sailboat

    As Phil mentioned, it’s a converted Soling apparently using the moulds developed for “Longshot”, which won the Australian championships for JOG yachts about 1978. “JOG” stood for Junior Offshore Group and was for offshore racing boats under 30ft LOA. Longshot also had about 75mm extra...

    sailboat bows

    Well….define efficiency and performance! :-). Arguably the vertical stem is only more efficient and faster if a boat is measured by LOA, often ignoring bow fittings. Increased waterline length, if nothing else changes, normally implicitly increases wetted surface so, all else being equal...

    Forces on mast foot

    Because they don't want to be instantly disqualified and possibly face a Rule 69 hearing. Spinnakers have never been allowed in National 12s.

    Easy way to reduce rolling on bilge-keeler?

    Why do you always have to insult people?

    Easy way to reduce rolling on bilge-keeler?

    The Symphonie didn't have a bulb keel. If the one you lived on was modified then maybe that was the problem with it.
