Re: Self steering harryproa downwind

-




I've also thought about this and I'm convinced it's possible, probably
easy with the schooner, lately I've been considering the una rig and
that should be possible too.
The schooner rig- Remember that Slocum got Spray to steer downwind by
over easing both sails, should be relatively easy to do something similar.
With the una rig my thoughts are to adjust balance by having the
forward rudder used as a daggerboard and by raising or lowering it
balance should always be perfect, then adjusting to self steer
hopefully becomes possible.
Just read that, wasn't too clear, hope it was understandable.

Are you trying to leave the helm to itself to get sleep, take a rest, etc? I was looking at a long trip on the Elementarry building at the moment, and accept...

The only way to find out is get out there and do it, but i suggest your biggest enemy will be sea state. It will be easier in flatter water. And you must be...

All true, still want to get out there and try it. harry, like any fast multi is going to be a problem for any self steering. An electronic auto pilot might...

A saver strategy would probably be to use a wind vane, but that would require a serious change to the steering system, and probably isn't too desirable on any...
