You’ve seen “turning 70” and other rotations, get ready for this . . . it’s a windy day on Newark Bay as

Margaret has forward starboard line and

Emma dashes to the point where a turn of greater than 90 degrees needs to be negotiated to rotate into the


The calculations of forces resisting and favoring this turn go way beyond my mere high school physics, and my high school physics class was more than 40 years ago.

I’m guessing what’s happening was accounted for by Newton and I’d enjoy hearing a description of forces like resistance caused by hull and keel design, ideal speed for flow across the rudder, and coordinated push of the two tugs deployed such that 5100 hp is near stern and 3000 hp opposite but toward the bow;  and taking into account the current/tide and wind.

But ultimately, I suppose the principles are the same as turns a canadagosling.
