In the attached:
To count passed vessels when the ships started their regular service, set cell B2 to 83 when the orange ship is very nearly half way across (that's how I left the attachment), just about to meet the blue ship which left from the other end at the same time, then click the Continue button and count the encounters(8)
To count the ships passing with an established schedule, move the scroll bar to the top (B2=0) and press the Continue button and count (15).
If you have a fast computer you may have to increase the delay in the macro (For j = 1 To 100: DoEvents: Next).
