Friendly race...need help (new sailor)
 
Hey everyone, I bought my first boat last year. My father and brother in law both have one too. We were going to do a "race" this summer down a long stretch of river. The 3 boats are: Grampian 26, Tanzer 26, and a CS 30. I want to do a rabbit start... so how do I determine how much time between each boat starting. I know from their ratings that the order will be Grampian, Tanzer, CS.

So, you have more than a month to come up with a good way to cheat and win.
No prob

The difference in the ratings is seconds per mile. So you could calculate how far the "race" is going to be and figure your start times like that. So with the numbers I would use as the ratings chair at my club, the Grampian is 228 , the Tanzer is 216, and the CS is 156. The Grampian would start first, then the Tanzer 12 seconds later, then the CS a full minute after the Tanzer. This is very simplistic and seeing as this is just a run what ya brung, bragging rights race, it should work for you. These numbers are for a one mile run though. If it is longer, then you would need to multiply the values by the miles.

Thanks for the help 🙂 The course is 8.8 NM s (so about 10 miles).

So the Grampian, then 120 sec later the Tanzer, then the CS 10 mins after the Tanzer.

Yes that would work, but as I said, it is very simplistic. There is also the current on the river. Some boats mat do better in it than others.

You could also use Time on Time calculation, which is what many phrf fleets use. Synchronize your watches, then everyone starts at the same time. As each boat finishes they note their finish time, then you apply the following method to calculate your corrected times:

Time on Time*(TOT) also uses ourPHRF*ratings but calculates*timecorrections as follows: Corrected*time= Elapsed*time*X 650/(550 +*PHRF). For example, if your*PHRF*rating was 120 and it took you 63.5 minutes to finish the race, your corrected*timewould be 63.5 X 650/670 = 61.6 minutes.

I know I can use that method as well. I just kind of like the idea of making it a race where we all "should" be crossing the line at the same time.

Yeah that is a fun way to do it. You could even make it more interesting by starting with your sails down. When the horn for each start goes, hoist your sails and go!

There is no such thing as a friendly race!

You got to multiply the numbers given by 8.8 not 10,otherwise you are giving an unfair advantage to the slowest boat. You are learning the ways of racing already take advantage of whatever you can, even in a friendly race.
