Epitomized by right captainship, the ship reached safely to the harbor.
I'm emphasizing the capabilities of the captain here. Is this correct usage?
Things epitomise qualities.
Epitomising sound captainship, the ship reached safety.
He epitomised sound captainship, and brought the ship to safety.
Since ships don't really have captainship, it's a quality of the captain rather than the ship.
I think it would be "epitomized with right captainship", since "right captainship" is the characteristic that the ship has perfected through the captain, the ship's epitome.
