redrb, yes, also because the stern is pushed outside the circle relative to the centerline the vessel gets through the tack more often than not....
If the said tri turned about the centerboard the turning circle would be more like this with no other factors considered
Doug interesting comment about the boared fwd and then being able to tack. If it is the relationship of the board to rudder distance, you may...

Did a canting keel job a while back where the designers drew some fancy hollows in the hull fairings to try and get 55 degrees cant. It looked...
Here's a thought or two. Will your designer/engineer put an insurable warranty on the design/construction. In other words do they have liability...
I sailed a radical bay 8000 with the biplane rig for the day in Thailand. I have to say that I was quite impressed with it. It was very simple and...
