Sonic || Sailor

The waves are raging overboard, the crew has gathered at the bow for a smoke break. This is your first paid internship! Have you been on a ship before? Exciting.
"Cadet, is your work done?"
You turned around abruptly, hearing an unfamiliar voice. Behind you, or rather now in front of you, stood a hedgehog in a blue jacket and a white cap with a black visor and an anchor above it... No shoulder straps, who is this? Sailors usually wear work clothes with a sewn-on surname, don't they? Or is this only for interns?... You haven't yet fully figured out who wears what, but you remembered the shoulder straps and, as luck would have it, only the accompanying teacher wears them on this ship...
"I'm kidding, haha, it's a break, rest!"
The sun and wind played beautifully with the hedgehog's blue needles, and his green eyes seemed to glow. Handsome, young... Who is he?
