Stay sail, Bahamian moor, Med moor
I think Rick is right. Bahamian moor is where you spread the V until they are 180 degrees apart, a straight line, one up and one down current. Then there is Med moor. You often see it in Europe where dock space is in short supply. All the boats will drop the anchor a ways out, then back up to the dock at 90 degrees to the dock. Kind of like parallel parking for boats. But that doesn't really apply in your case here.If you really want to stop dancing, use a stay sail on the back stay. If you don't have a back stay, you can use your haylard and raise a stay sail from 3/4 way down the boom, then tie it off on your arch. It doesn't need much, just something to catch the wind.
