Tacking in Wind mode
In WIND mode on sailboats there is also a tacking aid function. This
function may only be used when the boat is reaching and will when
activated take the boat from the course you are steering to the
computed course that gives you the same apparent wind on the other
side.
This tacking function as compared to tacking in AUTO mode can only
be used when you are sailing with the apparent wind as the reference
(WIND mode), and with apparent wind angle less than 80-90 deg.
A quick double press on DODGE will activate the tack function which
will prompt you for which way the tack should be performed. Press
PORT or STBD to select the tack.
2.7 Automatic Speed selection
The AP300X provides two different sets of steering parameters for
controlling the response of the boat at different speeds (HI or LO)
while in AUTO and NAV modes.
The AP300X always selects the HI speed steering parameters when
first switched on. This is a safety feature. After initial turn on, selection
of the steering parameters is done automatically, based on the
availability of input data from either an external speed log or an
external navigator, or manually.
The AP300X automatically selects the HI or LO parameter set. The
speed at which the AP300X changes from HI to LO (or opposite) is
determined by the "Transition Speed" set in the Installation Setup
Menu.
