    In my opinion it's very useful to be able to move the sail forward and back to achieve good balance on all courses in all wind speeds

    Like Robin's boat the sail on Footprints has the ability to be canted across the mast. I think for a low AR sloop junk rig this has the advantage in being able to minimise weather helm and obtain better balance with the boat.

    I must confess that I've never felt the need for it myself.  I don't seem to experience excessive weather helm on a reach, but then, I'm quite happy to reef as Fantail still romps along happily.

    I've been pleasantly surprised at how much easier a high aspect ratio rig is to handle. Coming up the Juan de Fuca Strait in a rising wind that was swinging from W to NW, I long-gybed multiple times without problems, when I would have been somewhat nervous under my Fantail sail.

    Yup.  Gybing Badger was less hairy than gybing Fantail, especially as I can't afford any sort of hoop.  I'm getting used to it now and it's less scary.  I've also found that having a length of shock (bungee) cord rigged above and below the sheet over the tiller improves its behaviour surprisingly.

    It's your Berrmudian heritage, me dear.  Just reef.  It's so easy.  Don't forget you were sailing with (at least) the equivalent of full sail and No 1 Genoa.  I know the racy boys all sail on their ears, but that's because it's so hard to reef.  I don't know of many boats that perform better at an extreme angle of heel and I'm sure everyone (Redwing included) would be happier sailing more upright!

    Marvellous, i met them briefly a long time ago and was out of news for a (long) while ... Happy to see them sailing along on their beautiful boat ...

    Indeed, it certainly is!

    This is very true. One of the reasons I am wanting to give Footprints a better rudder is that I have some friends who have a Newick 38' trimaran, which I admit is a whole different class of vessel than us junk rig monohulls. Anyway they had sailed from the United States to New Zealand in their trimaran and while here in NZ they decided to rebuild their rudder using a proper NACA foil shape. Once completed and refitted they could not believe the difference in performance from their boat. They claimed a significant increase in speed and much easier helming. Last I heard they were close to completing their circumnavigation after about 12 years of travel. This long time was not as a result of slow speed, but they were taking a very leisurely cruise around the world. Of interest is that it took them 17 years to build the boat so I like to think they are getting every year of building back in travel and rewarding experiences.

    Good luck David

    To serve science I suggest you don't add an endplate to the rudder at once, but if you make the low end squared off and horizontal, you can glue on a plate later.  Then you can better learn what factor improved the steering most.  My limited experience is that on a low aspect ratio rudder, an endplate will improve the rudder more than any careful streamlining of the rudder itself will do. 

    The late American boat designer, Phil Bolger used the endplate on many of his designs after having tried it on a traditional catboat. I have used it on a sailing row-boat and it really works.


    PS: All my jabbering about rudders here may sound a bit off-topic, but it is not: Better steering lets one get the best out of the sail with less fuss.

    Lots of interesting comments about rudders already. I collect the timber for my new rudder tomorrow and am looking forward to building it. Key features of the new rudder will be; Close up the existing 70mm gap between the leading edge of the rudder and the skeg by putting a bull nose on the leading edge of the rudder and fairing the skeg up to this; Doubling the balance area of rudder below the skeg by making the leading edge of the rudder vertical rather than the current 45 degree angle of the leading edge; Making the rudder blade a true NACA foil rather than the parallel sided blade that it is with a taper at front and trailing edges. While still not a high performance rudder this should hopefully produce significant improvements in helming Footprints.
