What are the wooden supports called that a vessel rests on while on the trailer?

Bunks are the wooden supports that a vessel rests on while on the trailer. They are specifically designed to provide stability and support to the boat, allowing for safe transport and storage. Bunks are typically bolted or attached to the trailer's frame and are covered with a material that helps protect the boat's hull from scratches and damage. Their shape and dimension are crafted to follow the contours of the boat, which helps distribute the weight evenly and reduces stress on the hull while being transported.

While the other terms may refer to different aspects of boat handling or storage, they do not specifically describe the wooden supports on a trailer. For instance, stands are usually used to elevate a boat when it's on dry land, supports can indicate a broad category of stabilization equipment, and cradles may refer to a type of support system used in various settings, but none match the specific role and design of bunks for trailers.
