Thanks Ad Hoc. I agree the 19.5ish degrees is independent of the hull shape, but even though the theory may assume the ship is a point, doesn't...
That's why I was thinking that if the bow angle was less than 19 degrees the wake might diverge from the hull. If the hull angle was greater the...
I suspect I'm on a 2+2=5 with this, but if wake leaves a boat at angle of around 19 degrees does it help to have a bow angle smaller than this so...
