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.
