What

 

is

 

it?

 

Cruising

 

Speed

 

is

 

a

 

set

 

point

 

at

 

which

 

all

 

the

 

standard

 

Pilot

 

setup

 

parameters

 

are

 

used

 

at

 

100%

 

of

 

the

 

input

 

value.

 

It

 

is

 

recommended

 

the

 

cruising

 

speed

 

is

 

set

 

to

 

a

 

value

 

close

 

to

 

the

 

speed

 

at

 

which

 

the

 

AutoTune

 

process

 

is

 

completed

 

if

 

possible.

 

For

 

most

boat

 

this

 

will

 

be

Knots.

  

Cruising

 

Speed

 

is

 

used

 

as

 

a

 

failsafe

 

boat

 

speed

 

input

 

if

 

Boat

 

Speed,

 

SOG

 

or

 

manual

 

speed

 

are

 

all

 

invalid.

 

What

 

does

 

it

 

do?

 

In

 

simple

 

terms,

 

if

 

the

 

Boat

 

Speed

 

is

 

less

 

than

 

the

 

Cruising

 

Speed

 

setting,

 

the

 

Pilot

 

will

 

apply

 

more

 

rudder

 

for

 

a

 

given

 

course

 

error.

  

If

 

Boat

 

Speed

 

is

 

greater

 

than

 

the

 

Cruising

 

Speed

 

setting,

 

the

 

Pilot

 

will

 

use

 

less

 

rudder

 

for

 

the

 

same

 

course

 

error.

PS

 

does

 

not

 

use

 

the
