Does it apply in the same way? I've read that Cats have a more jerky motion in the water.Oded Kishonyhttps://www.blogger.com/profile/05506528977182027366noreply@blogger.comtag:blogger.com,1999:blog-266108914902271629.post-37544227097435461172011-07-01T21:55:20.816-07:002011-07-01T21:55:20.816-07:00Thanks for the sketch, Aaron.

It is indeed a strange-looking sail plan, particularly as the width of a multihull makes a very strong base for a taller mast with a more efficient aspect ratio. Still, I expect the competition was rigged in much the same way, so Capt. Nat didn't have much to lose.<br /><br />Cheers,<br /><br />John V.John Vigorhttps://www.blogger.com/profile/02215080385571534292noreply@blogger.comtag:blogger.com,1999:blog-266108914902271629.post-63759022877543286942011-07-01T13:32:27.885-07:002011-07-01T13:32:27.885-07:00I took a look at Amaryllis (actually, Henry Ford&#...I took a look at Amaryllis (actually, Henry Ford's 1933 copy, Amaryllis II), and was struck by the sail-plan. It is very unusual to modern eyes — especially on a catamaran.<br /><br />It has a very-low-aspect-ratio main, rigged as a gunter, and an even lower-aspect-ratio jib with a full boom (!) that sits further forward than the fore-stay of what I'd have to call a bowsprit. (The fore-stay creases the luff of the jib on half of the tacks.)<br /><br />Here's a <a href="http://homepage.mac.com/aaronx/Amaryllis_500.png" rel="nofollow">link</a> to a sketch I made of it.<br /><br />The amahs were, I'm told, 33 feet long. Striking.<br /><br />Thanks for bringing my attention to this odd craft.Aaron Headlyhttps://www.blogger.com/profile/08936150018996105040noreply@blogger.com
