noun

screw ship; screw-propeller vessel

Technical term for a ship propelled by a screw propeller; used in maritime and engineering contexts.

スクリュー
Refers to the screw or propeller itself, not the whole ship.
プロペラ船せん
A more general term for a propeller-driven ship, not necessarily a screw propeller.

Compound of スクリュー (screw) + プロペラ (propeller) + 船 (ship). A direct borrowing and calque from English 'screw propeller ship'.
