Control Type
Depending upon the control method used to operate the morning lines. They are of two types:
Automatic tension mooring winch, self-tension winch:
Winches designed to heave in automatically whenever the line tension falls below a certain pre-set value. Likewise, the payout if the line tension exceeds a pre-set value. The use of the self-tension winches is not recommended except for mooring deployed at 90° to the ship axis.
Manual tension mooring winch:
Manual winch always requires a person to handle the controls for heaving or rendering.
