What are bunks used for in boating?

Bunks are specifically designed as wooden supports that cradle the hull of a vessel when it is loaded onto a trailer. Their primary function is to provide stability and support to the boat while it is being transported. Properly fitted bunks help prevent the hull from flexing or damaging during transit.

While securing a vessel in the water is important, this involves different mechanisms such as mooring lines or anchors rather than bunks. Similarly, providing a sleeping area onboard pertains to cabin amenities on larger vessels, which is unrelated to the supportive role of bunks. Anchoring a boat to the seabed involves the use of an anchor, which is also distinct from the purpose served by bunks. Thus, bunks are essential for transportation rather than for any of these other boating functionalities.
