australian nautical mile

i wanted to put this out to the SB brains trust.

i've had a question about the NM bonus prize of $1000 cash if the record is broken at burrum.

in the category outline i stipulated doppler tracks. the question has been asked of me if trackpoints are accepted. certainly for the NM champ at the burrum comp both TP and D will be accepted.

for the Australian NM record however i stipulated doppler as it is more accurate BUT i am easy either way.

question is? what is the record currently substaniated with, trackpoints or doppler?

are there any other question i should ask>

why change ?? DOPPLER !

Thats right, it was done at the now defunked Clayton Speed Channel it was probably one of the best places in the world to do NM runs approx 5km long, looks like Burrum will be the only place now in Oz that is capable of producing high NM runs.

cheers for the feedback guys,

i'm not looking at changing anyhting just trying to get a feel for what constitutes the australian record.

ie. are trackpoints accepted generally?

my gut feel is that doppler is the future and is more accurate so doppler should be the yard stick.

not being tech savy, does the trackpoint advantage reduce over distance?

is this it?

All current postings on GPS-SS must be in Doppler to be shown in top rankings.
Doppler is not the future, it is the present!
Trackpoint postings have much lower credibility and so could not really be considered 'Records', even if they are unofficial.
Trackpoint error is usually the same or more over longer distances. For shorter, straight line distances it can be less error if the 'direct line' path is calculated (using just the start point and end point) rather than the sailed path (using every single trackpoint). Not sure if the current versions of the softwares give this option anymore.

Ironic that its in Beaut Bute Montanna.

totally agree hardie, and that's why the burrum windfest uses both sets of data.

i set a doppler only condition for the NM record as it is an australian record that's being chased.

without throwing you a potato, GTC has the database so you guys have by default become the gate keepers.

unfoirtunately there is no national body to make the call, i guess it falls to "US"

that said, if everyone agrees to dissagree then i'll accept both.

after re-reading my post i wanted to clarify i'm not asking the GTC to set the standard in australia for judging records that you guys have no control over. i'm just looking to the "experts" for their opinions.

it would be shame to see someone take the record with track points and then have people not recognise it.

wanderers whom are running the burrum event are affiliated with windsurfing qld. edit* but only as far as gaining access to the AWA scheme. how you become national is beyond me

I doubt you'l need to worry about it Justin, there's only a handful of guys in that league that will be serious challengers and I'm sure they all use doppler, maybe a garmin backup I suppose but I'd reackon its a realistic expectation for people going for the record to be using doppler as a primary source of data.

sounds like a plan.

Yeah, It suits TOM CHALKO.

guys the event will except both doppler and trackpoint.

it is only the australian NM record that will require doppler for the cash prize as the current record just happens to be held with doppler data we are using doppler. if the record was held with track points then we would use that.

i should also point out that we are only talking about the record being beaten at burrum and specifically in relation to the cash prize.

any other attempts anywhere else in oz or at burrum on track points will be for others to decide.

also, i don't know tom chalko, have never met the man and have never had a conversation with him.
