What is typically the material used for bunks in boating trailers?

The material commonly used for bunks in boating trailers is wood. Wood provides a sturdy and reliable surface for safely supporting and transporting boats. It is favored because it can effectively distribute the weight of the boat while also being relatively inexpensive and easy to repair or replace. The wood bunks can be covered with a marine-grade carpet or other protective materials to enhance grip and reduce wear on the boat's hull. This combination allows for stability and protection during transport.

While other materials like plastic, aluminum, and fiberglass can be used in various boating applications, they are not as widely utilized for bunk construction. Plastic may not provide the needed structural support, aluminum could be too slippery, and fiberglass, while durable, might be heavier and more costly compared to wood.
