Race Scoring using the Time-on-Time Method

For the series races, SPSA uses the “Time-on-Time” method prescribed by US Sailing. This method better compensates for large handicap spreads in PHRF sailing clubs and allows for adjusting the corrected time by a wind factor to give more time allowance for light days.

The formula for the “Time Correction Factor” is: TCF = A / (B + PHRF)

US Sailing suggests that A be set to 650, but notes that any value can be used. The Regatta-Tech software uses the same value for the A & B variables when making a wind adjustment.

The B variable is the wind correction factor. The use of this is subjective from club to club. Typically we use the following values to adjust for the various wind conditions:
480 – Heavy, 15kts +
550 – Average, 10-15kts
600 – Light, 5-10kts
650 – Calm, 1-5kts

The corrected time is then calculated by multiplying the elapsed time by the TCF.

So given a PHRF rating of 194, a light day, an elapsed time of 43:53 the corrected time would be calculated as follows by the Regatta Tech software:

600 / (600 + 194) = .7557
43:53 = 2633 seconds x .7557 = 1989.7 seconds == 33:09.7

2014-15 Race #11 & #12 Results are Posted

Another beautiful day on Tampa Bay… Except for the hole in 2nd race that a few of us sailed into and abruptly came to a halt. A little light on the wind, but we made it around and it was a fun day. Today’s race conflicted with huge Island Nautical flea-market and that impacted participation a bit. I know I skipped the first race to make it. Next season we’ll try to coordinate our race schedule with our Sponsor, Island Nautical so we don’t overlap. After the race, several of us managed to navigate our way through the maze of the St Pete Grand Prix track to meet up at Corrigan’s for some post-race refreshment.

I wish to extend a big welcome to the USF Offshore Sailing team which has joined our series with their J/24 “Anarchy Panda” in the Spin B class. If any of you guys have some left over J/24 gear you don’t need, these guys would probably love to have it.

Upcoming in April we have our final two series races of the 2014-2015 season on Sat 4/4 & Sat 4/18. Those of you in the trophy hunt can’t afford to miss a race right now, everybody is VERY close.

Stay tuned for some summer schedule updates. We have a variety of non-race events being planned for the off-season.

2015 Twilight Sailing

I spoke with Gloria today and she said the SPYC is going to run twilight races the next two Friday’s (3/13, 3/20) for practice. These won’t count toward season standings, but will give you the opportunity to get your crew some practice. The official season starts the first Friday in April. Note, to encourage more participation, the non-spin boats will sail the cruiser course this season, not the windward/leeward course the spin boats will use. I hope to see a good SPSA turnout!

As usual, if you want crew or need crew, meet at the Sailing Center before the race. Let Gloria know if you want to participate at treasurer@spsa.us

2014-15 Season Race 9 & 10 results posted

What a fun day! The temperature warmed back up and we had good wind for all but a few minutes of lull. A pleasant change from many of the very light air races we’ve had this season. Thanks to the crew of Back Off for being race committee. They were awarded a tie for first for volunteering. About 20 of us met at Courigan’s afterwards for some post-race fun. Even if you don’t race, I encourage you to come out for the after party!

Results

Mi Sueño moved back ahead of Desiderata into first place in cruising. These two boats are tied in points at 5, so the tie breaker goes to the winner of the last race.

In Non-Spin, Eclipse holds a 6 point advantage over new entry “One Up”, but One Up continues to put the heat on and close the gap with 6 races to go. Remember, any tie-breaker goes to the winner of the final race!

Spin A has the top 3 boats within 2 points. Warrior moved ahead of Tack Tick for the season as the two boats are tied at 7 points and Tack Tick DNC giving Warrior the tie breaker on the last race. Back off is right on their tail with 9 points.

In Spin B, Hula Girl moved ahead of Odyssey by one point for the season.

The next 6 races will be critical for those in the hunt in these divisions!
