What

 

is

 

it?

 

TWS

 

Response

 

allows

 

the

 

Pilot

 

to

 

automatically

 

bear

away

 

to

 

a

 

lower

 

target

 

angle

 

if

 

the

 

wind

 

speed

 

increases

 

above

 

the

 

level

 

it

 

was

 

when

 

the

 

Pilot

 

was

 

engaged.

 

What

 

does

 

it

 

do?

 

Applies

 

a

 

semi

permanent

 

change

 

(bear

away)

 

to

 

the

 

TWA

 

target

 

if

 

the

 

TWS

 

has

 

increased

 

since

 

the

 

Pilot

 

was

 

engaged.

 

If

 

the

 

TWS

 

drops

 

back

 

to

 

the

 

initial

 

mean

 

TWS

 

value

 

(or

 

below)

 

then

 

the

 

Pilot

 

target

 

will

 

come

 

back

 

to

 

the

 

originally

 

commanded

 

TWA

 

value.

 

This

 

allows

 

the

 

boat

 

to

 

be

 

driven

 

faster

 

and

 

also

 

assists

 

in

 

broach

 

prevention.
