<p>To permit the use of a large diameter propeller (20) extending below the ship's base line (11), the screw propeller (20) is included in a thruster unit or pod unit (6) forming a containerized propulsive unit (6, 60), which is mounted to the hull (10) with the screw propeller (20) at a distance behind the transom (13) where a stern wave crest (40) is formed, and the transom (13) has at least one generally vertical recess (13') for attaching the containerized unit (6), so as to permit the containerized unit (6) to be tilted from a normal cruising position to a position where merely a minor part, or preferably no part,of the rotary screw propeller (20) is located below a base line (11) of the hull (10).</p> |
