    ... And what about the lack of drama in all kinds of cases - when you're weighing anchor, when you're wanting to enter harbour slowly, etc. etc - the sails will quietly look after themselves when you don't need them, but will deliver the appropriate amount of drive when you do.
    ... And what about the way a junk rigged boat is much more easily sailed than a bermudan boat by a short-handed or single-handed crew.
       I've got used to sailing past bermudan rigged boats downwind, because it's too much trouble for them to pole out the foresail.
       I've got used to being the only boat sailing in difficult, variable conditions, because it's easier to turn the engine key than it is to turn the genoa winch handle.
       No, you're not ranting, Annie, just reminding us of what we fortunate junk rig sailors tend to take for granted.

    One of my wishes for the online JRA seems to be coming true: more people with miles and fewer in their armchairs are discussing the rig.  IMHO, windward ability has been to JR what capsizing is to multihulls, with far too much emphasis on this one aspect and far too little on all the advantages that also need to be taken into consideration.  Why, oh why, does no-one ever point out that rigged boats can't sail downwind efficiently, without excessive effort and dangerous tying down of sails that make a dramatic alteration of course all but impossible?  Why, indeed, don't more people point to the number of boats with triangular sails that invariably motor to windward?  What about the amazing advantage of being able to sheet the sails hard in in flat calm conditions, which prevents the boat from rolling and senses immediately the wind returns?  Flat sail or cambered - all junks benefit from these tremendous and insufficiently recognised benefits.

    It's great to hear seamen discussing the realities of cruising and voyaging rather than theories gleaned from too much reading and too little time on the water.

    Hope that doesn't sound like a rant.

    Stavanger, Saturday

    I am glad to see that the Hasler-McLoed (HM) rig has been moved into the "Sailplans – in current use". In fact one could have shown 3 - 4 such sailplans side by side with raising aspect ratios (AR) from the shown diagram and up to "Badger"s hi-AR sails. That is one fine thing with the HM rig; it is so easy to adjust the AR to fit the needs of different boats.

    I regard Johanna’s rig to be nothing but a HM rig, quite similar to the "Sumner" rig (see PJR) with its 3 top panels and 70° yard. Hasler and McLeod here made a very clever cross between the horizontal panel sails and the fully fanned sails that both could be seen in China.

    My sloop "Johanna" is so generously rigged than in a F6 she will be down at 4 panels and in a F7 she only carries 3 panels. In these conditions her sail has been transformed into a fully fanned sail with very moderate camber – and she performs very well. The yard is still peaked to 70° producing an effective luff. Only in "light" winds, F5 and below, will the parallel batten panels come into serious use. In other words; the lower panels become my "genoa 1" while the fanned top section becomes the "storm sail". It’s a paradox, but it works.

    That'll do nicely, Graham. I've added the picture and your text to the "sailplans in current use" page. But if anyone wants to refine the wording...
    The JRA is better than a democracy!
    Thanks,

    Well stated, Graham. You've gathered several cruising priorities into one bundle, so to speak. Best of luck with your conversion project, whatever style of sail. Nice-sized boat for it.
    Cheers,

    Point taken, Kurt. I transferred a lot of that stuff over from the previous website, and perhaps didn't give it enough thought. Yes, the Hasler/McCleod and Colvin rigs are still giving good service. I refer frequently to PJR for details of rigging, to avoid having to re-invent the wheel.  PJR can't be faulted, up to the stage of development that was reached at the time of publication. Blondie Hasler had the most inventive mind of anyone I've ever met, and we innovators fully acknowledge the debt we owe him. With his inventive mind, if he were alive today, he would be at the forefront of rig development, and we would be trailing in his wake.
    Can you suggest forms of wording that indicates that whilst those earlier rigs are still around ( and junk rigs last a very long time), and some (but not all) will continue to serve their owners well, a designer of a rig nowadays does well to take into account all the later developments? Can you help me to reshuffle the "sailplans" pictures into a more appropriate order? I'd like to add more, if anyone can supply them.
