What is the main purpose of the "H-Frame" on an accommodation ladder?

The main purpose of the "H-Frame" on an accommodation ladder is to facilitate passenger pickup and drop off. The H-Frame serves as a structural component that helps to create a stable platform at the top of the ladder, which is essential for safely boarding and disembarking individuals, particularly in a marine environment. Its design allows for proper alignment and support, ensuring that passengers can safely transition between the ship and the pier or boat.

The H-Frame can help keep the ladder stable and upright, making it easier for individuals to use without the risk of slipping or falling. Given the dynamic conditions on the water, where ships may experience movement due to waves or currents, having a well-supported and stable access point is paramount for safety when transferring passengers.

While the other options do have their own significance in different contexts—such as securing the ladder or providing support—none specifically address the unique functional design of the H-Frame in relation to passenger transfer, which is its primary purpose.
