I am new in this forum, however I saw some of the things you guys wrote about Omer wing sail that I would like to explain.
In general, the boat with Omer wing sail has much better performance than the same boat with standard rig, in terms of pointing up wind as well as boat speed in any wind direction.
She is easier to handle short handed and also very easy to trim.
It is a variable geometry wing sail and the camber is not only very easy to change from port to starboard, but also to trim the rate of the airfoil asymmetry (when the wind is blowing hard you make it almost symmetrical while in light wind - max. asymmetrical airfoil).
The wing always rotates into the wind (the leading edge is always facing the wind) thus, in down wind you keep on using the lift
force rather than drag like in the case in standard rig.
It is also very easy to tack upwind - the only thing you have to do is to turn the wheel
and to change the camber (by an electric
switch ) while the main is kept sheeted in.
There is no need for any extra sail, including spinnaker
. she is very fast down wind.
I tested the rig in strong winds. There was no problem since you can reef the wing exactely the way you reef a main sail. The wing can be reefed to 75%, 50%, 25% of sail area.
You are invited to visit the web site gallery (Omer wing sail - soft and variable wing sail
) and see how she sails
operates in various wind directions, in down wind, how it is reefed, how the camber is changed from port to starboard etc.
