Moderated Re: Choosing between designs and rig options

 

Well thats cool. I'm sure i can make the mast/gaffstyle top/rings from carbon myself. Then have the sail cut at the place thats supplying Wharram builders with sails. They already have the tooling setup to do it right.?

So im set on the build i belive?

860 open?
Single wingsail rig?

Ill be getting the plans after the hoildays?

Do they include the single mast version, OPEN DECK??

THXS AGAIN?

The Wharram ¡°Wingsail¡± is a very good sail.?
At the boat show in Amsterdam, 1982. We were there with the SC 435 and the first carbon fiber bent Gaff. The founder of Polyservice and I developed this Yard.? Not many persons knew carbon at this time as a construction material. The Yard was made for my new Butterfly design. I developed this rig with a big sleeve around the mast for better aerodynamics. Same for the bend Gunterrig gaff/yard. We discussed this rig with James and Hannecke. They developed from this idea their ¡°Wingsail¡±. The Butterfly rig was a nice experiment and learning tool. One result is the parallel rig, which I used for the DUO 425 with big success. I use the sleeve for aerodynamic reasons and on freestanding rotating masts to unfurl the sails.?
By the way, the Wharram ¡°Wingsail¡± rig can be used. But not for parallel rigs, because the rig uses stays. The ¡°Wingsail¡± mast must be stronger because no spreaders can be used.
