How Autopilots Work

The purpose of this introductory section is to briefly describe what an autopilot does and some of 
the things you should expect when using an autopilot with your boat.   

Manual Steering 

Every vessel has unique dynamics, which depend on its design, shape and dimensions, as well as 
current  speed,  loading,  and  sea  conditions.  The  net  result  is  that  every  boat  (or  rather,  every 
unique boat 

design) 

“steers” in a unique way. 

To understand what an autopilot does when it is steering your vessel, it is helpful to think for a 
moment about steering a boat by hand. 

When you are holding the boat on a given Heading, you know from instinct and  experience 
how much rudder to apply, and how fast to apply it, to keep the boat 
on-course.  Corrections are usually just a small, quick movement of the helm to one  side, then 
back to the dead-ahead position. 

You won’t always try to correct when the boat rolls or accelerates off a wave, especially in heavy

 

seas – because when the boat rolls back the other direction, it will usually come right back on-

course.

Instead, your experience reminds you to allow the boat to yaw those necessary degrees on

either side of the Heading, to reduce the fight.

To turn the boat to a new Heading, instinct and experience again remind you how much

rudder to use, and how fast, to get the boat turning at your normal rate of steer.

If the boat is not turning as rapidly as you want (for example, with a cross- or cross-current

 

holding

 

back the bow), you slightly increase the amount of rudder.

On the other hand, if the boat is turning too fast, you reduce the applied rudder a bit.

You then gradually reduce the applied rudder, as the boat approaches the desired Heading.

You might even put the helm over opposite for a moment, to stop the boat swing more quickly –

in order to come to the desired Heading without overshoot.

The single most basic purpose of an autopilot is to control the vessel the same as a human operator

 

would … to let the boat “work with the seas”, yet still maintain as straight a Track as possible in the

 

current conditions, on the desired Heading or Course.

The 

SP38

 Autopilot System uses the latest generation of ComNav’ s carefully-designed, well-proven

 

steering control algorithms, which are based on many years of designing and manufacturing

 

autopilots.

There are a number of parameters used in the steering algorithms, collectively referred to as

“Steering Parameters.” The 

SP38

 Autopilot system has been tested on a wide variety of boats, of

 

different types and sizes. The default settings for the Steering Parameters are average values

 

derived from that testing, and provide a good starting place for most boats.

During sea trials, and later on normal operation, you may want to adjust some of those values, so

 

that they better match your boat’s unique design dynamics.

However, the information in this section can be applied in general to any 

Sitex

 autopilot, and is

 

not

 

necessarily specific to the P-Series.
