Hi,
Would you tell me the difference between flights and races?

Consider a race with 100 entries. Many race organisers decide that this is
far to many boats to run in one start or indeed in one physical area. So
they split the competitors into flights, in this case say 4 flights of 25
boats; flights are typically named with colours; lets call them
red,blue,green,yellow. So flight is just a boat/competitor designation,
nothing more.
What happens then is that each race in fact consists of two separate races
(in this example) with a start having two flights: e.g. red+blue in one
start and green+yellow in another. In this way the organisers have broken
up 100 boats into two physically different groups of boats and usually
having them sailing different courses with different race offirers etc.
Racing continues by rotating the flights, e.g:-
course 1 course 2
race 1 red+blue green+yellow
race 2 red+green blue+yellow
race 3 blue+green red+yellow
At this point every flight has sailed against the other flights once. The
series continues by repeating this patten possible awapping courses to share
them out equally.
Scoring flights is slightly different but very very simple. All that
happens is that the results of the two courses are entered *as if* all the
boats (100) were in one big race, so you end up with multiple firsts and
multiple seconds etc. Because of the flight rotation this doesn't matter
and everything avarages out in the end.
There are lots of variation on that theme, for exmaple if there are lots of
flights but a small numnber race races courses, each start may combine more
then one two flights. etc etc.
Other scoring changes include race tie resolution - only applied to boats in
the same flight and the series scoring rule 8.2 has to modified in a way
that I don't yet understand but I'm sure Ralph is about it explain it to me
in detail so I can implement it.
Sailwave can score races sailed as flights but it's most useful contribution
is the ability to accept the days results in *any* order - i.e. the race
courses and the starts can be mixed up - Sailwave knows the flight each sail
number is in, and knows which starts each flight is in, so it can work out
which position to assign next. This is useful because the guys on the water
may radio in results as they are happening; there is no restriction at all
on the order that sail numbers are presented to the Sailno wizard.
See also the ISAF web sit and their APpendix KE document - although I think
it's called somehing else now KD?
