Dear Professor :
Someone told me that the arc of visibility differs as to :
Sailboat
Powerboat.
Is this "someone" full of it " ?
If this someone is not full of it , how can it be that 225 is correct ?
A smart alec

sides of the boat. This is incorrect. If this was so, the arc would be
225+225

225 total.
