Simple observation.
When a row boat advance, the wake is very broad, 60 to 90 degrees and can detach
from the bow (go faster than the boat).
When you watch a speed boat, the wake is perty sharp, maybe around 15 degrees or
even less if you go fast enough.
On a cruise ship going at cruise speed, the width of the wake from the bow at
the stern level is MUCH narrower than the length ot the ship.
