I think what you might need is a Digital CCTV recording system.
Like something at:
http://www.y3kvision.com/acatalog/pccctv4ver.html
This could be ideal if one camera is placed in the race hut which can record
the start line and audio of people taking in the race hut whilst calling
numbers of boats on every occasion a boat passes the start finish line. Plus
also recording any VHF messages reported by safety boats.
If possible, place the three other cameras to look at each of the turning
marks, to record any incidents at these points.
Quality of images will depend on quality of cameras, and equipment used
Not sure how or if this will work on a committee boat

Thanks for that Malcolm
There has been little response to this request for help so I
can only presume that I am breaking new
ground with this approach.
Your comment are most useful as I have never owned a
camcorder so needed to establish some sort of
specification.
References to action replay, anti-shake, freeze frame
quality, seconds on the timer etc are great.
I also agree with you that the camera would not be the main
source of information, purely a back up
to the race officer's call.
On the media side, I am hoping that there is some sort of
mini DVD which can be replayed on a
computer rather than a TV.
It is my intention (dream??) to project information re the
results etc through a projector linked to
a PC/laptop which can also play the visual recording if there
are queries, rather than force sailors
into a protest room before they can see the evidence.
Some of you may recoil with horror at the thought of showing
competitors possible mistakes but I do
not see anything wrong with letting competitors know that my
actions have worsened their result &
suggesting that they go for redress.
Don't know how many race officers are members of SUG but will
provide feedback later in the year if
it works.
If not I will have a cheap camcorder for sale ;-))

I didn't see any other responses to this post, so thought I'd
better respond
before it gets lost.
I've experimented with a video camera for starts and finishes
while being
race officer for minor club races - on an inland dam in light wind.
I held the camera in front of me on the boat, pointing down
the line to the
pin. This was mainly for the purposes of possible evidence
for OCS incidents
at the start and for verifying uncertainty with close
finishes (after the
race, the video could be set into `action replay').
Especially for starts,
it was important for the camera to be doing its own thing, while I was
concentrating on timing and checking boats being over the line early.
I hadn't considered it to be used for scoring, but it should
be possible.
Most video cameras can show date and time in the frame, but
probably not
seconds. This could be overcome by running a stop watch on
shore against the
video sequence. Most cameras also record audio and have good picture
quality, freeze frame and even `anti-shake' However using a
video camera in
strong wind and/or at sea in a big swell would be difficult.
(Most footage
or still photos of sailing boats is done in light wind -
photographers don't
seem to like getting wet trying to capture scenes in adverse weather!)
My camera ( a Samsung), uses a Mini DV cassette, which could
be transportd
by RIB to shore. However, it would need another similar
camera to play it
back, as these cassettes don't fit into a VHS tape player. I
think there is
another (larger?) type of cassette wich can fit into an
adapter for playback
on a video machine - but that would require a different
(older?) type of
video camera.
