What type of surface is best for bunks to prevent slipping?

A rubberized surface is ideal for bunks because it offers excellent grip and traction, reducing the likelihood of slipping. The rubber material conforms well to the shape of the boat’s hull, creating a more secure fit that helps to stabilize the boat while it's on the trailer. This feature is particularly important when loading and unloading, as it ensures that the boat does not slide off the bunks unexpectedly, minimizing the risk of accidents or damage.

In contrast, a rough surface can cause wear to the boat's finish and may not provide a consistent hold, while a smooth surface might be too slippery, increasing the chance of the boat shifting during transport. A metal surface can also be problematic; it lacks the necessary grip and may lead to corrosion, which could further compromise the stability of the load. Furthermore, metal can be prone to scratching the hull or causing damage if the boat shifts at all. Thus, a rubberized surface is the best choice to promote safety and protect the boat.
