The sub-surface contact face ensures that the fender remains effective even when the vessel's hull is partially submerged, which is a common scenario in tidal waters or when dealing with vessels that have deep drafts.
The sub-surface contact face works by providing a larger surface area for the vessel to press against, distributing the impact forces more evenly. This reduces the risk of damage to both the vessel and the dock. Traditional fenders that only provide surface-level contact can fail to protect the submerged parts of the hull, leading to potential damage and increased maintenance costs.
The sub-surface contact face is designed to adapt to the varying water levels, ensuring consistent performance regardless of the tide. This adaptability is crucial for ports and harbors that experience significant tidal variations. By maintaining effective contact with the vessel's hull at all times, the fender ensures that the energy from the impact is absorbed efficiently, reducing the stress on the vessel's structure.

By distributing the forces more evenly, it prevents localized stress points that can lead to structural damage over time. This not only extends the lifespan of the docking infrastructure but also reduces the need for frequent repairs and maintenance.
The materials used in the construction of the sub-surface contact face are typically highly durable and resistant to marine conditions. This includes resistance to saltwater corrosion, UV degradation, and biofouling. These properties ensure that the fender remains effective and reliable over long periods, even in harsh marine environments.
