What Are the Multifunctional Uses of a Landing Craft’s Side?

When landing craft berth at docks, alongside other vessels, or operate near mudflats, the hull side is the first part to come into contact with the external environment. The hull sides of modern aluminum landing craft are typically equipped with rubber fenders or bumpers designed to absorb impact energy during berthing, thereby protecting the hull structure and coating. For commercial operations requiring frequent docking, the quality of the side fenders directly affects the hull’s maintenance cycle and service life. A client involved in port logistics stated that his vessel docks more than a dozen times a day; without fender protection, the hull would have been badly damaged long ago. While the docking function of the sides may seem simple, it represents the most frequent instance of hull contact during daily operations. When selecting fenders, it is recommended to choose fender strips with appropriate thickness and hardness based on berthing frequency and dock material; fenders that are too hard can damage the dock, while those that are too soft fail to provide adequate cushioning.

Side doors can be installed on the sides of landing craft and equipped with folding boarding ladders or diving ladders. This configuration is extremely valuable for diving operations, scientific research, and personnel transfer scenarios. Divers can enter the water via the side door and ladder without having to climb over the ship’s side, significantly enhancing safety and convenience. Side doors can also serve as auxiliary access points during berthing, allowing personnel and lightweight supplies to board or disembark from the side of the vessel when the bow ramp cannot be deployed. Take an 11-meter aluminum landing craft as an example: with the optional side door and diving ladder, this vessel can simultaneously handle both cargo transport and diving support operations, significantly improving asset utilization. A customer who operates a diving club in Hainan noted that since installing the side door and diving ladder, guests’ entry into the water has become much smoother, leading to an increase in repeat business.

Landings typically feature handrails installed along the gunwales, extending along the edge of the deck. These handrails not only provide a safe support for crew members walking on deck but also serve as auxiliary attachment points for securing cargo. When operating in wind and waves, the gunwale handrails are a vital aid for crew members to maintain their balance. For passenger landings, gunwale handrails and guardrails are indispensable safety features. On aluminum landing craft, side handrails are typically welded or bolted in place and made of the same material as the hull to ensure they remain secure and rust-free over the long term. A boat owner who operates island-hopping tours noted that the first thing passengers notice upon boarding is whether the side handrails are sturdy, which directly influences their assessment of the vessel’s safety. Though a small detail, this is the first step in building customer trust.

The sides of a landing craft can also serve as mounting platforms for external equipment. Common side-mounted items include: removable outboard motor brackets, spare fuel tank racks, life raft storage racks, scuba tank racks, and mounting points for various operational tools. These external attachments do not occupy deck space but significantly expand the landing craft’s operational capabilities. For engineering vessels that need to carry a variety of tools, the side-mounting system makes accessing and retrieving tools much more convenient. Our engineers can incorporate standardized mounting interfaces into the hull sides based on the customer’s specific operational requirements, facilitating the retrofitting or adjustment of equipment at a later stage. Incorporating these interfaces during the design phase is both more cost-effective and safer than welding modifications later on.

In emergency response and scientific research operations, the functionality of the hull sides is further expanded. During rescue operations, the hull sides can serve as climbing points for people in the water, enabling rapid rescue in conjunction with gangways and life rings. In scientific research operations, the hull sides can be fitted with hydrographic monitoring equipment, sampling tools, or sonar transducers. The high structural strength of aluminum landing craft hull sides makes them suitable for mounting various external devices without compromising the hull’s integrity. A client engaged in nearshore environmental monitoring installed water quality samplers and current meters on the gunwales, enabling real-time data collection during operations. This approach increased work efficiency several-fold compared to the use of fixed monitoring stations in the past. For scientific research missions requiring frequent deployment and retrieval of equipment, the convenience of gunwale operations directly determines the efficiency of data collection.

Not every vessel requires the full range of multifunctional side-of-hull features. When selecting configurations, decisions should be based on your core operational scenarios: if cargo transport is the primary focus, fenders and mooring points are essential; if diving or personnel transfer is involved, side doors and boarding ladders are necessary; if the vessel is used for engineering operations, it is advisable to reserve mounting interfaces on the side-of-hull in advance. The side design of aluminum landing craft offers a high degree of customization flexibility. Incorporating mounting interfaces and reinforced structures during the hull construction phase is more cost-effective and reliable than retrofitting later. We recommend thoroughly discussing your operational scenarios with the manufacturer before purchasing, so that the sides become a workspace that truly serves your business needs—rather than merely a section of the hull.
