Chapter 4 : Start display
Deckman incorporates a display for use specifically when starting a
race. With the position of the two ends of the start line entered,
Deckman will give you the distance and time to each from the boat's
current position, and will also display the current laylines and line bias.
Clicking on start on the icon bar will give you a starting display as in
Figure 4.1; the direction of start is always from the bottom of the
diagram to the top, so that the port or pin end of the line is to the left and
the starboard or committee boat end is on the right. The line above the
start line indicates the present line bias—it is drawn from whichever end
of the line is favoured, the port end in the diagram. The pairs of lines
drawn from each end of the line are the laylines.
