Congratulations to SCSC members at Pepin Open

The St. Croix Sailing Club did well again at the Pepin Open in Lake City over the 4th.  We didn't have anyone competing in the Spinnaker 1 Division, but John Larson & crew aboard Ragtime took 1st place in Spinnaker 2, Rick Hughes & crew on Blew Bayou took second and Harmony took top honors in the non-spinnaker division.  Fast Lane and Hot Damn!! also competed.

Will you host next Beercan?

There are still many opportunities to host a Beercan, check the calendar, if there isn't a host listed, it's available.  The club will will reserve the point and provide $150 toward food & beverages.  Contact any board member if you would like to be involved. 

Regatta Meet & Greet

We will have a "Meet & Greet" at the marina clubhouse in Hudson at 6:30, Friday August 29.  This will be a good time to register for the regatta, talk to some of the completion and get psyched for the racing.

Labor Day Regatta

Time on Time Race Scoring
By B. J. Battig, Race Chair

I have gotten several questions this year regarding the approach and formulas behind the Time-on-Time (TOT) scoring method that is used by the Club.  Here is my best shot at explaining how the concept works and how it is incorporated into the scoring program by borrowing explanations from several web sites.

The largest handicap fleets in the United States, including St. Croix Sailing Club, now sail under the Performance Handicap Racing Fleet (PHRF) system.  The PHRF supplies a single correction factor that is applied regardless of the conditions of the race.  Both time-on-distance and time-on-time handicapping can be used under PHRF.

The Time-on-Distance (TOD) method calculates a fixed time allowance, based on the length of the course to compute the corrected time.  An advantage of TOD is that is simple and you can tell exactly where you stand at any point in the race.

Time-on-Time (TOT) scoring is somewhat different in concept.  A time correction factor (TCF) is generated for each boat, which is the ratio of the potential average speed of the yacht to an arbitrary standard yacht, and is generally expressed as a multiplier.  As an example, if the reference boat has a handicap of 1.00, a boat with a TCF of 0.90 will have a corrected time equal to 0.90 times its elapsed time.  A boat with a TCF of 1.10 would have a corrected time equal to 1.10 times its elapsed time.  Under the Time On Time (TOT) scoring method the time allowance for a given race depends on the elapsed time of the race. 

To get the corrected time for your boat for a specific race, you simply multiply the elapsed time by the TCF for your boat.  Remember all the time units must be the same.  For example an elapsed time of  1 hr 5 minutes and 30 seconds equals 65.5 minutes or 3930 seconds.  I have added the Time-On-Time correction factors to the rating summary on the Club website.

Exactly how is the TOT conversion calculated in the scoring software, Quick Score, used by the club?   The Club has used PHRF-Lake Ontario Time-on-Time scoring for several years.  The Time-on-Time scoring multiplier is derived from a formula based on interpretation of the published results of the original H. Irving Pratt Ocean Race Handicapping project at M.I.T. as modified by Lake Ontario in 1985.  For those of you who are a math wiz, all the formulas are referenced on the Lake Ontario web-site.  http://www.phrf-lo.org

How does Time-on-Time scoring help?  It's no secret that larger boats have an advantage upwind, especially in heavy seas (going a mile to weather usually takes longer than sailing a mile off the wind). Time-on-Time scoring gives more time to the slower boats in such conditions. Off-wind races however, usually provide an advantage to small boats. These races are generally faster and Time-on-Time scoring correctly allows the slower rated boats less handicap.

In light wind conditions, tall masted boats seem to catch more of the "higher air" due to vertical wind gradient and are less affected by leftover sea conditions. Again, because the average boat velocities are slower, the races take longer to complete and the smaller boats get proportionally more handicap time.

In summary, Time-on-Time does NOT factor distance into the results at all.  It generates a time correction factor for each boat as compared to a scratch boat, from mid fleet for comparison.  In the case of the SCSC fleet a PHRF of 171 (Hakuna Matata and Gallivant).  If you look at the results for these two boats you will note their correction factor is 1.00, i.e whatever their elapsed time for the race equals their corrected time.  For other boats the time correction factor is multiplied by their elapsed time to give a corrected time.  The correction factor is fixed for each boat for every race.  To find out your boats time correction factor visit the Handicaps/Divisions Page. 

Change Made in Racing Rule 3(c) by ISAF

After the US SAILING edition of The Racing Rules of Sailing 2005-2008 had been printed and distributed, the International Sailing Federation (ISAF) made a change in rule 3(c).

Rule 3(c) as it appears in the printed rulebooks has been deleted and replaced with the following rule:

(c) where the matter is not one to be determined under the rules, not to resort to any court of law or any tribunal until all internal remedies provided by ISAF or by the Court of Arbitration for Sport have been exhausted.

This new rule, which begins to apply on January 1, 2005, covers matters that are not “to be determined under the rules,” such as a boat owner challenging a measurer’s decision or a one-design sailor challenging a class rule change. Such incidents occur between regattas when there is no possibility of protesting or appealing under the racing rules. In such a case, new rule 3(c) will require that the remedies provided by ISAF and by the Court of Arbitration for Sport be exhausted before a boat or competitor goes to court. (The Court of Arbitration for Sport is an international institution created in 1983 that arbitrates sports-related disputes. The court’s web site is at www.tas-cas.org.)

Rule 3(c), as it appears in the printed rulebooks, was considered unnecessary because rule 3(b) points out that a decision on a matter covered by the racing rules is considered final after the appeal and review procedures provided in the racing rules have been exhausted.

In addition, US SAILING made two changes in Appendix F, in rules F1.1 and F1.3. Rule F1.1 was changed to accommodate a request from the Intercollegiate and Interscholastic Sailing Associations. The change in rule F1.3 corrects an unintended omission in rule F1.3. Both changes took effect on January 1, 2005.

Insert the following sentence between the first and second sentences of rule F1.1:

However, an appeal or request arising from an event run under the procedural rules of either the Intercollegiate Sailing Association or the Interscholastic Sailing Association will be forwarded to the association appeals committee for the ICSA and ISSA.

Change rule F1.3 to read as follows:

F1.3 Appeals of decisions of a protest committee acting under rule 69.1, appeals of decisions of a protest committee of a US SAILING national championship, and requests by such committees for confirmation or correction of their decisions shall be made to the US SAILING Appeals Committee.

Race Notes

Because of the number of boats in each division, we're going back to four starts with the divisions starting in "reverse" order, Division 4 first, then Division 3, then Division 2, then Division 1.  The Race Committee also decided to go to a 3-minute sequence for starts.  This will keep the time between starts shorter and only add a couple minutes to the overall starting time compared to last year's two starts.

To compensate for the faster boats starting first, the time limit has also been changed.  The 45 minute time limit from the first boat finishing will not consider the J-80's, that is, the 45 minute timer will start when the first boat from Divisions 1, 2 or 3 finishes.

There are some new courses this year, so make sure you have a copy of the sailing instructions on your boat.

Scoring will again be Time-0n-Time.

Yachts racing in SCSC scheduled events will be assigned a PHRF handicap rating formulated from US Sailing Association rating information.  Ratings assigned will be based on a nationwide average of PHRF member fleet ratings for that yacht.   All member fleet ratings are based upon Standard Boat Assumptions.*

Yachts which are Non-Standard or don not have a PHRF rating will be rated according to the guidelines provided by U.S.Sailing for rating a Custom or Unrated Yacht.

Yachts Racing under incorrect handicaps are subject to disqualification.

*Standard Boat Assumptions:

1. The Spinnaker pole length is equal to "J".

2. The Spinnaker maximum width is 180% of "J".

3. The Spinnaker Maximum length is equal to 95% of the Jibstay length, i.e. .95 x "I" x "J".

4. The Genoa "LP" is between 150% and 155% of "J".

5. IOR Batten length restrictions are followed except in cases where the standard boat has full length battens

6. The Boat is in racing condition

7. The Boat has a folding or feathering propeller, a two bladed solid propeller in an aperture, or a retractable outboard.

8. The Hull or appendages are unmodified.

A Yacht is non-standard if it does not conform to all items listed above, with the exception of item 6.  Please supply the appropriate information from the diagram below to the SCSC Ratings Committee.

Dimensions:

LLJ (Luff Length)___________________

LP (Distance from Clew to Luff, measured perpendicular to Luff):__________________

Main Sail Dimensions:  E (Foot Length)______________  P (Luff Length)____________

Spinnaker Dimensions:  LLS (Length form Head to either Clew):____________ G (Maximum Girth):__________

Spinnaker pole length:______________  Whisker pole length:__________________

SCSC Rating Committee reserves the right to declare any Yacht "exceptional" and either not provide a ratting or rate it outside the normal class rules.
