Prestart 3 (Last items)
The last group of items is the actual start metrics  starting line information and timing.
 If
you're using racing software, ping both ends of the line to set up the
course.
 Deternine
the favored end.
Run the line in both directions. The mark
with the lesser true wind angle (without regard to sign) is favored. The amount of favor is half the sum of the
true wind angles (5º). The approximate distance to weather
advantage is the length of the line times this angle divided
by 50 (60ft).
 Time
the line.
Determine how long it takes to run the line
on starboard. You will need to know this if you don't want to overrun
the pin.
 Practice
Vanderbilt starts.
A Vanderbilt start is where you
go to a
certain location (the takeoff point) from the right end, round up on
starboard at your optimum upwind sailing angle and hit the line at full
speed exactly when the gun goes off.
Reset Back R/B at the starting line, then
use Back Range & Bearing to
establish a consistent takeoff point.
Adjust this point as necessary so on the run to the line, you are at
the optimum sailing
angle, and going full speed before you expect to encounter enemy
traffic.
 Start
your stopwatch 1 class ahead.
Then at the 5 minute gun, which you
will be ready
for, use Sync to set it exactly.
