Many thanks for your advice.
Can you please explain why you need to have the two sets of results, is it to compare where the finishing positions of competitors would be with and without personal handicaps. It certainly is a good way of establishing an appropriate personal handicap to ensure that they all finish reasonably close.
Our method of personal handicaps is very basic, the competitor receives a time allowance and starts a number of minutes before the other competitors. They also have the added advantage of starting in clear wind. Your method is far better. Having the 2 sets of results will enable us to apply sensible personal handicaps. The personal ratings can be changed to obtain similar corrected times across the fleet.
My initial objective however is an understanding how I cater for the different ratings applied to different boat configurations sailed on different days, as outlined at the bottom of this e-mail. Does your club allow double handed boats to sail single handed, and if so, do you apply a different rating value? It is not quite the same as a personal handicaps.

Hi Joe
I have been using Sailwave for a couple of years for both class racing where I record the position and for handicap racing where I enter the elapsed time.
I am also using it with the standard PY from the RYA and to calculate the positions using a Personal Handicap for each helm.
This is achieved from one race which then gives 2 results.
Each helm is set up on the Edit Competitor page twice with the same data except they are assigned to a different fleet. i.e Std and Personal
On the first page where you can see all the helms the fleets are sorted into the 2 fleets and then sub-sorted using the “ctrl” function by name ( or whatever suits your data imput style).
Using the the User Interface function from the top boxes I then activate the “competitor Aliasing” box .
Now you can go back into “edit competitor” in the Personal fleet and tick the box at the top marked Alias.
This will then give you all the helms who are in the other fleet (in my case the std fleet). You choose the same helm that you are aliasing from this fleet and then come back out.
You need to do this for all you helms and you will then have 2 fleets but will only have to enter the elapsed times once for each helm.
Enter the times for each helm in the std fleet. The same times will appear against the equivalent helm in the Personal fleet.
Now you can apply a new Rating to each helm in the Personal fleet. We use a % to help us understand what we are trying to achieve. 100% for the average helm and 80% for the very good helm and say 120% for the ones we want to encourage. We then apply this % to the PY of the boat that is being used by that helm. EG for a Laser helm who is very good with a personal handicap of 80% we would give him a rating of 868 instead of the 1085 that the RYA are offering. (by the way we don’t want this helm to win the personal handicap event as he will be doing well enough in the std racing!)
To apply these “personal” ratings you go into the first race on the front page for each helm in the Personal Fleet and right click then from the 3 options at the top choose “Rating” and left click. There are 4 boxes that could be filled in – choose the bottom one “Race rating” and type in the Personal Rating you have decided for this helm (in my case it will be 868. Now check the box marked “use until the next race rating is specified”. This will then apply this handicap to this helm for the whole of that series or until you change it.
It is true that when you publish the results Sailwave will split the 2 series into 2 overall results and will have applied the std PY you gave to this craft when setting for the std fleet but will have used the Race rating for each helm in the Personal fleet results BUT it will show the std PY on the results page for both fleets. HOWEVER if you set the publication set up to show each race it will display the personal rating as set up in the paragraph above in the Personal Fleet results and the std PY in the std fleet results.
Hope this helps

Hi Joe,
Welcome to the Sailwave User Group. There are a lot of people here that I’m sure will be pleased to help you.
I’m not quite sure what you are attempting to do
I assume you will have 1 Sailwave file for each event and another for the series is this correct?
or are you trying to have all the racing in a single file?
I am the new developer for Sailwave and also a long time user although the majority of use is with class racing. Although I do some regattas using PY but don’t have the experience of the issues that arise from Club PY racing that many of the members here will hopefully help you with. There are often many alternative ways of achieving your goal with Sailwave and it is a matter of finding the one that works best for you.
Certainly setting up different class names will work with Sailwave. As you change the class the PY will then change. Although this may cause some problems when submitting to the RYA - I’ll let others comment here.
I know that ratings can be input manually and that value is used to calculate corrected times, how ever my understanding is that only the default rating ratings values are displayed, so this may lead to queries on published results.
I don’t quite understand here as if there is one Sailwave file for each event then the PY displayed will be the PY used.
If you are talking about the series. Is your series all the races with Elapsed Times and Ratings or are the positions transferred to the Series. If you transfer the positions then you don’t need to know the Ratings

Hi John,
I have recently joined the user group and as Rear Commodore of Swarkestone SC (SSC) in Derbyshire, I would like to get the OODs to use Sailwave. We currently use the system, but only to record finishing positions, not elapsed times. We intend to submit our returns to the RYA to use in their analysis application to work out ratings applicable to our club, this needs elapsed times.
One limitation is how Sailwave caters for all the different ratings we apply at SSC for each class. One example of this is a Com et Trio, where we have 3 different ratings:
a) Rating for Sunday when sailed double handed
b) Rating for Sunday when sailed single handed
c) Rating for Sunday when sailed single handed on trophy days
I have worked out a solution within Sailwave, but would appreciate your feedback as an experienced user of the system.
Setting up Ratings Values
Include within the ratings file, 3 different ratings for the Sunday series, each one with a unique class reference and ratings value.
The ratings csv file imported and used by Sailwave would be as follows:
PY, Comet Trio, 1085
PY, Comet Trio (S/H), 1060
PY, Comet Trio (S/H on trophy days),1055
Setting up Competitors
To enable the correct ratings to be applied to the Sunday race series, there will be multiple entries for those competitors with different ratings, these would be as follows:
Class, Sail No, Helm Name
COMET TRIO,417,Derek Smith< o>
COMET TRIO (S/H) ,417,Derek Smith
COMET TRIO (S/H on trophy days),417,Derek Smith
This configuration allows us to pick the competitor and associated class and rating value. Sailwave can then calculate corrected times from the elapsed time entries. There will be no need for the OODs to use a calculator and input rating values, Sailwave will do all the calculations.
I know that ratings can be input manually and that value is used to calculate corrected times, how ever my understanding is that only the default rating ratings values are displayed, so this may lead to queries on published results.
Another factor we need to consider is how we deal with our SI rule allowing one boat/class change per series. I believe that we will need to create another Sailwave file at the end of the series and just enter the finishing positions, with one entry for each competitor.
If my proposed set up of the system is a recognised method of dealing with the above scenarios, then confirmation would be very much appreciated.
