The Quick Route facility also allows you another way to set the
positions of waypoints (see also Sailing the Course below). Click on the
Quick Route icon, point the cursor at the waypoint you wish to move (it
will turn red). Hold down the left mouse button and drag to the required
position. If you are moving a quick waypoint (q1, q2 etc), then the
waypoint will be moved; if you try to move a fixed mark, then a new
waypoint will be created in the position you drag to with a Quick Route
name.
You are also able to add or remove waypoints from the current route
using the Quick Route facility. To add a waypoint to the current route,
select the Quick Route icon and then point the cursor at the waypoint
after which you want to add the new mark (it will turn red). Without
clicking the mouse button, move the cursor to where you want the new
waypoint and double click, followed by save as route. To remove a
waypoint, select the Quick Route icon and then highlight the waypoint
you wish to remove from the route (it will turn red). Hold down the left
mouse button and drag the waypoint to either the previous or next
waypoint, release the mouse button.

All of the above preparation should ideally happen before the race
begins; during the race you then just instruct Deckman to go to the next
waypoint and all calculations will be done with respect to the new mark
(the name of the present leg is shown in the box at the top of the
display):
(F2)
next waypoint—clicking on this means all
calculations are made with respect to the
next waypoint.
(Shift F2)
previous waypoint—all calculations are
made with respect to the previous
waypoint.
