If you cantilever the mast, you can skip those.<br /><br />RE wind on the beam... My guess is that both sails would be working in clear air. With the wind diagonal to the hull, seems the upwind sail would affect the other... so you'd have a better and worse tack.<br /><br />Our miz is offset about 2ft to port.

They'd then interact as any two master, without factoring additional interference.

Most of the catamarans with hull stepped rigs use parallel rigs (one in each hull, opposite the other).<br /><br />But yeah!<br /><br />Dave ZDave Zhttps://www.blogger.com/profile/13241033623115158564noreply@blogger.comtag:blogger.com,1999:blog-3580987459140037495.post-22927338050075148982020-09-07T16:15:00.621-08:002020-09-07T16:15:00.621-08:00Think that these could be the same for catamarans ...Think that these could be the same for catamarans with the masts placed on one hull only. <br />Anonymoushttps://www.blogger.com/profile/10845541535607570192noreply@blogger.comtag:blogger.com,1999:blog-3580987459140037495.post-3568975277096270272020-08-06T13:04:44.729-08:002020-08-06T13:04:44.729-08:00Phil got the sail area just about right and, more ...Phil got the sail area just about right and, more often than not, we exceeded our "hull speed". <br /><br />The short mast and low CE meant that when reefing down we maintained performance and as the balanced lug rig is self-vanging so the odd jibe was non-problematic.<br />RLWhttps://www.blogger.com/profile/03722124194083306429noreply@blogger.comtag:blogger.com,1999:blog-3580987459140037495.post-41101709189962368352020-08-02T11:31:30.026-08:002020-08-02T11:31:30.026-08:00Hi RLW,

I think one of the under-mentioned problems of an uncontrolled jibe is that sails balanced when running wing and wong jibe into sudden and radically unbalanced mode (all one side). <br /><br />Aside from any danger to shrouds and other gear, this imbalance riskes round-up and broach before following seas.<br /><br />DZDave Zhttps://www.blogger.com/profile/13241033623115158564noreply@blogger.comtag:blogger.com,1999:blog-3580987459140037495.post-24574197772889372492020-08-02T11:10:41.009-08:002020-08-02T11:10:41.009-08:00Hi Roberto,

They later told us they thought we were totally insane.<br /><br />Totally green was more like it. We were under such good control, we thought nothing of this (though it was, like, totally awesome under snow-blown Chilkoot mountains.<br /><br />Knowing better these days, I deem it safer than it looked, but still not exactly advisable!<br /><br />Dave ZDave Zhttps://www.blogger.com/profile/13241033623115158564noreply@blogger.comtag:blogger.com,1999:blog-3580987459140037495.post-40598879306377485522020-08-02T10:44:29.992-08:002020-08-02T10:44:29.992-08:00Nice illuminating of the directly downwind advanta...Nice illuminating of the directly downwind advantages of a offset mizzen mast. Makes sense likewise for the main to lessen undue force on a self steering gear? Shemayas "Auklet" was pictured running due downwind with the Reddish geomtery lugsail squared off like a big square sail on the boats centerline. With a offset mast a Van Loan or Hasler sail might do basically the same thing.

They worked just fine.<br /><br />That said, the off-centeredness of our boat drove folks nuts and we were often forced to listen to long-winded lectures about how the boat could not work as designed in spite of the fact that we were obviously sailing and for us to be sailing the boat had to sail.<br /><br />So it does go...<br /><br />RLWhttps://www.blogger.com/profile/03722124194083306429noreply@blogger.com
