Sec.  113.43-3  Alarm system.



    (a) Each vessel must have a steering failure alarm system that 

actuates an audible and visible alarm in the pilothouse when the actual 

position of the rudder differs by more than 5 degrees from the rudder 

position ordered by the followup control systems, required by part 58, 

subpart 58.25, of this chapter, for more than:

    (1) 30 seconds for ordered rudder position changes of 70 degrees;

    (2) 6.5 seconds for ordered rudder position changes of 5 degrees; 

and

    (3) The time period calculated by the following formula for ordered 

rudder positions changes between 5 degrees and 70 degrees:



t = (R/2.76)+4.64



Where



t = maximum time delay in seconds

R = ordered rudder change in degrees



    (b) The alarm system must be separate from, and independent of, each 

steering gear control system, except for input received from the 

steering wheel shaft.
