    Ok, Ill race a scale Mari Cha IV.... Its a schooner too! If it has to be a gaffer a Bristol pilot cutter is the way to go, I've sailed on a fulsize one. Theres not many better feelings than overtaking the modern plastic fantasic cruisers at the helm of a nice old 80 ton 60' gaff cutter!

    By thew way thats a very nice boat John, everone should visit this man's hompage.

    Luff 'em & leave 'em.

    I Propose a new sailing Class, a Class for REAL sailing boats.
    This will embody designs taken from actual boats with little or no alteration allowed, other than Scale.
    This Class is for Scale Sailing Boats.

    Does this qualify? []

    John, have you looked at the Vintage model Yacht group? Earl Boebert is a member here andpart of that group you might want to e-mail him or look them up on amya.org
    I wonder how you feel about this: Almost nothing is more pathetic to me than seeing a model 12 meter or glorious J boat with a squat low aspect non scale rig-it just makes my skin crawl!
    I have a solution: the reason those boats are done that way is scale effect which reduces the model's capability to carry sail as you well know. So in order to sail these boats most people seem to think that in order to keep the underwater part of the boat pretty and scale that its ok to "clip the wings" of these awesome boats. Instead of doing that why not allow a "clip on" fin and bulb that creates enough additional Righting Moment that a scale rig can be used. Then when the boat is on the water instead of looking like a giant squished the rig the boats would look like the actual boats out on the water!! You can't see the keel when it is sailing and when you haul out you could remove the clip on fin/ballast combo...

    I wish it was my boat, because it was done in excellent workmanship. Belongs to a sailing friend in France !

    The wing mast, and depth of board and rudder are not to scale, but overall it was sized down to 1.2 meters. If you look close, he even scaled down the tram netting between the main hull and floats, and it has the "Fuji" logo on the tramp netting as well. (Hard to see with the white boat stand.) Both of us were building from the main trimaran design. I decided to stay with a performance version and wave piercing hulls - while he elected to replicate FujiFilm boat. He even added the small radar dome at the rear of the cockpit - but didn't get into the detail of winches, etc. There has to be a trade-off somewhere for "working" boats and deck items taht can catch the sheets while sailing.

    After he hit the water with it, his comments were that it was fast, but a bit on the heavy side.

    John, I didn't see that keel idea on your website but I think it is absolutely terrific that you are using it!!! What the hell good are these so-called scale boats that look so horrible when they are sailing!Way to go!!
    And by the way that rig on Dicks multi is NO WAY near scale!!! Scale would be MUCH taller.....
    I mean, imagine how good an EC12 would look with a REAL 12 meter rig instead of that flattened down thing they use now -and the J boats-- Well, you know!

    I've studied model J boats a bit :-) What John Black did in 1935 to make a 36"LOA version of "Yankee" is instructive: He reduced the sailplan to 90 % of scale, and then to fool the eye he further reduced the plan *by shortening the boom only? This *increased* the aspect ratio and fools the eye into thinking the plan is taller than it really is. (He also increased the draft, but after all, he is reducing this boat to 1/42 of full size.)

    Another thing to make it look more "like a J" is to adopt a double headed rig. Based on a trick from 1895, you can do this without complex sheeting arrangements. Details in our next newsletter, at the printers now :-)

    Cheers,

    Earl

    John, thats terrific! Allows the boat to be scale ON the water which is so cool! And then take the fin/bulb off and your scale out of the water.
    Thats the way it should be done. Great job!
