    Aw, y'know... it'd just be a drag anyway.  ;->
     
    Psst - you're going to get me in trouble with the webmaster.

    Fortunately, he is away :-)

    In a long ago correspondence Arne recommended that I put a "wing" on the bottom of the rudder to improve Seablossom's handling, especially, if I remember correctly, in reverse.  Bolger was a strong advocate of wings on both keels and rudders, and it doesn't seem like it will take a great deal of work to put one on there, made out of 1" exterior plywood, of which we have some sizeable scrap left over from a recent farm project.
    Jeff, I'd leave the rudder alone for now. It looks amply big enough to do the job. The end plate can have a beneficial effect but if you do not need it, it's just more drag.

    But this is an optional extra. If you don't fit it with the HM rig that Paul drew for you, then you don't fit it on a Fantail sail either. I have received Paul's sail drawing, and the aspect ratio is not so very different, so the helm loadings are not going to be so very different either. Seablossom, with her long straight keel, will run straight, and her rudder is of a reasonable size. I don't expect you to have control problems off the wind, so I don't expect these extra lines to be needed.

    Annie doesn't use them (but her mast is raked forward, so there is more balance area).

    I have an HM rig of course but also have 3 degrees forward rake in the mast and 10 - 15% of the sail forward of the mast.  I can sail upwind in 15 knots under full sail and am perfectly balanced (can leave the tiller free).  Off the wind in the same breeze I drop a couple of panels and the boat tracks beautifully under self-steering with no sign of rounding up.  I could carry more sail in this strength of breeze - I have run with just the same two reefs in winds of 20 - 25 knots - but cannot see the point in driving the boat hard, as the rig is so amazingly efficient when sailing downwind.  So, for me, the answer to downwind sailing is just to tuck in a reef rather than slide the sail across the mast.  That was what I originally intended to do but have not found it necessary.  Arion, however, has always been a well behaved boat off the wind.  Other designs may require other techniques.

    And thus far, have never had an issue with weather helm, in spite of getting 7 knots out of the wee ship!

    Yes, I do have a two part purchase on the forward end of the boom, and a two part purchase to the middle of the boom, both led to blocks at the foot of the mast and then aft.
