On which type of davit does the davit head remain at the same height during operation?

The Radial Davit is designed such that the davit head remains at the same height during the launching and recovery of a lifeboat. This type of davit operates with a radial arm that moves in a circular motion, ensuring that the weight of the lifeboat and the forces involved do not cause significant vertical movement of the davit head. This characteristic allows for smoother operations and enhanced stability when handling lifeboats, especially in potentially rough sea conditions.

In contrast, other types of davits, such as Gravity Davits, often involve a mechanism where the davit head may move up or down as the boat is launched or recovered, which can introduce additional complexities and safety concerns during operations. The Initial Davit and Fork Davit may also not maintain a constant head height due to their design and operation methods, which can impact the ease of use and the ability to make adjustments during the boarding of the lifeboat.

Understanding the specific function and design of the Radial Davit is crucial for lifeboat operations, as it significantly contributes to the safety and efficiency of the lifeboat deployment process.
