For laughs and grins I want to unofficially score our next upcoming ocean race – Tri-Point Race/ August 23rd Ventura, CA - using the Texel Ratings to see how it scores against the Portsmouth DPN rating. In looking over the site there is a great deal of information on how to calculate your rating, as well they have a current listing of all the beachcats numbers, but could find the scoring calculation.

Has anyone set up spread sheet to calculate the corrected time, or have the formula?

its's time on time scoring.

Use texel ratings exactly like the DPN USAA rating.

Sailwave allows you to score both ways. Providing that you keep the boat class spelling exact in the rating database.

Right now.. only the F16's are really out of synch in the two rating systems.

Have a look at www.sailwave.com

So it is not a time on distance? OK, could you plug in say a PHRF or a ORCA formula and get an accurate result?

Neat program, and a real "niffty score sheet"; however, I may be missing something - does this give you the
calculation or calculate predicated on the race information you input.

There are no ratings for beach cats that are time on distance rating tables.

If you developed a time on distance ratings set, you could use sailwave to score a regatta much like you would with a PHRF ratings series.

I don't know how complex the ORCA formula was but you can enter your own ratings formula into sailwave and process the race data to compute finish's as well.

Sailwave is a scoring program... It computes the final corrected times for any number of rating systems that you might want to use. It will also score a highpoints series.

Does that clear things up?

In addition to calculating a race order of finish.
Sailwave has two other features that may confuse you. It has a ratings calculator which will compute the current ISAF rating for a beach cat using specific measurments of the hardware. This is an add on and included for convenience in the case that an odd boat shows up for a regatta and you want to come up with a rating.

The other calculation that you see for a race is the ETW or elapsed time to win. This calculation computes the actual time in real minutes and seconds that you need to save on the water in that race so that your virtual time would give you the win over the boats in the race. A related calulation is a back calculated rating. eg... What rating did you actually sail the boat to that day. (Of course had you sailed the boat to your rating... you would likely have won the race.)


Neither of these calculations are used in determining the rating for a boat class.

Have fun!

Yes "kinda sorta", So I understand you still have to manually calculate the corrected time and enter this in to the results or caculate the race and enter in the place finish.

No

you enter the time of day of the start for the handicap class

You enter the average windspeed for the race.

These are found when you right click the race tab in SW.

Then as each boat finishes a race, you record and enter the time of day of the finish using the SW Wizard. (it would also accept elapsed time and lots of other formats but this is the basic ideea)


The program looks up the rating from the database of USPN and TEXEL ratings that you have given it. Does the math, applies the rating, calculates corrected time, ranks the finish order and gives you finish PLACES top to bottom.

You can have the data diplayed any number of ways from place to corrected time to actual elapsed time.

You can also print the results in any number of formats but usually you print the overall results as finish position with throwouts and you add to that a print out of each individual race which gives you elapsed, corrected and the ETW and RTW numbers.

And hopefully in the near future, when you have an active internet connection on your computer, you will be able to submit your Portsmouth ratings straight to US Sailing from clicking an item a drop down menu in the software! (I'm working on this with Colin - the creator of Sailwave after seeing that he was already doing something similar for the RYA).

Yes, I saw that last night while playing with it - that can save time. Also downloaded the *csv file you had uploaded to their site - thanks, and joined the yahoo group.

Still had a problem getting the program to auto-calculate the corrected times (using last Saturdays race as a learning tool)

I am wondering if Sail Wave ever does a web cast on How To!

I'll admit that the learning curve on the software is pretty steep initially...it took me a while to learn to use it. However, I attest that it is incredibly powerful and takes regatta scoring tasks that used to take an hour or better down to minutes. Once you dial in the scoring forms, you can score everything and have it posted in no time at all. Colin put in a great deal of thought on the entry forms and you can fly entering results using the wizards.

There is a user's group on Yahoo that is run by the Sailwave person. They can be of good help:
