Don’t know if this is of any interest to anyone…

Is Gary Smith a SUG member (I should know I know!), if so maybe you would like to let us in on the secret.

Hi
no sorry not a SUG member

(wasn’t even sure what that was…ooops)

though it may be handy to clubs wanting to try Pratt racing if
sailwave could be tweaked to give the results?

regards

Gary

Hi

I work out the results for Gary at Eastbourne for the PRATT racing.

PRATT racing is a personal handicap system we run on Wednesday nights for lasers.

All the PRATT times are taken from the corrected time on the PY system to allow Lasers and Radials to take part.

Each sailor has a personal handicap assigned to him at the start of the season or carried over from last year. This can be a positive or negative number and relates to the number of minutes that need to be added or taken off that sailors corrected time. E.g. If someone has a corrected time of 4215 seconds and a PRATT handicap of -3 their PRATT time would be 4035 seconds.

The times are then sorted, winner being the person with the least time as normal. The top three place people get a minute added on to their handicap and the bottom three get a minute taken off.

As for scoring the season. We run on a high points system. The leader would score the number of starters in that race, second would get the number of starters -1 and so on. If you DNF, OCS or DNS you get 0.

We then also allow discards through the year (normally one discard after 5 races, two after 8, and three after 11). Then the people that sail every race start to lose points. People who did not race just discard a 0. This means you don't have to sail every race to have a chance of winning.

Just for a extra bit of fun, people can play a Joker once. They have to indicate this on the signing on sheet and what ever they score that week they get double points. If they don't finish or the race gets abandoned then they lose their joker.

At the moment I work this out on two spreadsheets but I think more clubs are talking about trying the system out. I have no idea how this could work with Sailwave but would be good if it could.

Has anyone worked out how to get sailwave to work with PRATT yet? I am going to spend some time on it soon and see if i can figure it out, but any suggestions would be greatly appreciated.

I think the Personal Handicaps feature in sailwave might be used for this? I don’t know if the handicap can be changed for each race though the way that PRATT works. With that and High Point Scoring I am hoping to get it working.
