Normally Brakes must be ___________tightened to achieve the required holding capacity of the line's Minimum Breaking Load.
Direct Answer
Option C: 60%
Mooring winch brakes are typically tightened to approximately 60% of the line's Minimum Breaking Load (MBL). This ensures sufficient holding capacity while allowing for some dynamic loading and preventing over-stressing the mooring lines, a standard practice referenced in mooring system design principles.
