There are, however, ways of changing the position of the current
waypoint to make it fit in with your observations once you start racing.
Choosing menu>waypoints>set waypoint—or by clicking on the icon
shown left on the tool bar—gives you a number of methods to set/adjust
the position of the current waypoint (usually, these would only be used
with the movable marks in the triangle sector, as the fixed marks
shouldn't normally move!):
to boat sets the position of the current waypoint to the
position of the boat. For example, when
rounding a particular mark for the first time or
to set the start mark.
drag current
waypoint allows you to highlight and then click-and-drag
and current waypoint only to a new position.
Once you release the mouse button, you will be
asked to confirm the move.
Ww/Lw from
windward sets the position of the leeward mark and finish
line by range and bearing from the windward;
brings up a dialog exactly the same as that
shown under Set windward/leeward (see
Setting the start on page 4.3) except the
bearing you set in the top box is from the
windward to the leeward mark.
triangle from
lee you position the windward mark by entering a
range and bearing from the leeward.
RB from prev
WP set the position of the current waypoint as a
range and bearing relative to the previous mark.
RB from boat set the position of the current waypoint as a
range and bearing from the boat.
