System
What
is
it?
To
react
rapidly
and
proportionately
to
any
change
in
wind
speed
before
it
causes
a
course
error
or
broach.
What
does
it
do?
Applies
a
temporary
change
(bear
‐
away)
to
the
TWA
target
during
a
gust.
The
target
will
return
to
the
original
target
after
a
short
time.
Applies
a
'fast'
bear
away
and
a
'slow'
return
to
target
TWA.

gain
control:
start
with
a
low
value
and
increase.
This
setting
should
be
adjusted
so
that
the
boat
*just*
applies
enough
rudder
during
gusts
to
prevent
the
boat
being
over
‐
powered.
"Gust"
is
defined
as
a
deviation
from
the
average
wind
speed.
If
any
increase
in
wind
speed
remains
in
place
(i.e.
the
average
wind
speed
increases)
then
the
Gust
Response
will
slowly
reduce
to
zero.
For
changing
conditions
where
the
wind
is
increasing
and
decreasing
in
longer
periods
then
we
recommend
the
use
of
the
Adaptive
Wind
Control
(“TWS
Response
‟
)
function
instead
of,
or
as
well
as,
Gust
Response.
If
you
use
TWS
Response
it
is
recommended
that
you
set
the
gain
level
for
that
feature
first,
then
set
the
Gust

gain

No
course
change
that
will
exceed
the

be
commanded
by

Excessive

can
cause
a
temporary

(within
the
safety
limits)
IMOCA
60
Advisory
We
have
experienced
mixed
results
using
Gust
Response
on
IMOCA
60s.
Using
the
TWS
Response
feature
seems
more
effective
for
this
class.
If
you
use
Gust
Response,
we
recommend
you
use
it
with
TWS
Response.
If
you
elect
to
use
the
feature
we
recommend:
Gust
Limit
=
5kt
,
Response
Rate
between
3
and
5
.
