Galling is a form of wear caused by adhesion between sliding surfaces. When a material galls, some of it is pulled with the contacting surface, especially if there is a large amount of force compressing the surfaces together.Galling is caused by a combination of friction and adhesion between the surfaces, followed by slipping and tearing of crystal structure beneath the surface.alling is caused by macroscopic transfer of material between metallic surfaces, during transverse motion (sliding). Galling occurs frequently whenever metal surfaces are in contact, sliding against each other, especially with poor lubrication.
Depending on wind & circumstances and size of the vessel there can be hundreds even thousands of pounds of pressure on the sail and the line, so winches are an important tool for the sailor. Grinding (and tailing) is the act of rotating the winch handle to pull on the line inorder to tighten a sail. On larger sailing vessels, the crew operating the winch is often referred to as the Grinder. Because the winch wonât pull a line tight unless the line is tight on the winch, both grinding and tailing actions need to occur simultaneously. On the American Cup vessels (for example) while one person can do both actions, It takes two - or one person for each action when speed and every second counts.
