How does the Ovni perform upwind? Can you estimate the average angle between windward and COG and the speed, tacking in different wind forces and sea state?
The actual angle can be anything between 50 and 60 degrees. The speed depends on the strength of wind of course. I have sailed upwind under all wind conditions and the boat has performed well, but it is very important to have good sails, to reef early, to set the sails well, etc. It all takes more effort than on a keeled boat, but it works!
