The Single Point Davit system is suitable for launching a fully manned rescue boat against unfavorable conditions of a trim up to ___ degrees and a list of up to ___ degrees.

• A. 5 / 15
• B. 10 / 20
• C. 15 / 25
• D. 20 / 30

Answer: (B)

Understanding this is about how much the ship can tilt while a rescue boat is being launched from a single point davit. The davit system is designed to tolerate certain trim (head-to-tail tilt) and list (side-to-side heel) so the boat can be lowered safely even in rough seas. For a fully manned boat, the weight and dynamics of lowering demand conservative limits. The specified safe limits are a trim up to 10 degrees and a list up to 20 degrees. These values keep the boat clear of the hull and davit during deployment and ensure the winch can control the load without exceeding the system’s capability. Exceeding these angles would push beyond what the davit is designed to handle, increasing the risk of collision, water ingress, or loss of control during lowering.
