|The “H” Fleet uses the popular CHRF rating system which is based
solely on the actual performance of the boat as equipped and as crewed.
Handicaps change after every race and are based on the average adjusted
seconds per mile of the best 4 of 5 races. See below for an understanding
of the handicapping formula.
The “H” Fleet will normally sail triangle courses like K, D, or A
to H. H to BB or C. The start time will be 1705 hours, and the early
start is intended to assure that all H Fleet competitors round the weather
mark on the way to H before other fleets start, to be out there
in the best wind, and to get back to the bar first.
Competitors may fly chutes or not, there is no deduct or adder either
way. The handicap will quickly adjust itself to whichever the preference.
The following are our objectives:
Wet Wednesday H Fleet
To accommodate participation in Wet Wednesday Racing for boats desiring
to compete under the Club's popular handicap rating system rather than
the PHRF rating system.
To accommodate competitors who prefer a triangle racing course.
To insure that the H Fleet be compatible with the existing Wet Wednesday
program and that to the fullest extent possible remain clear of other fleets
to minimize conflict.
To improve the prospects that H fleet participants can finish before
the wind dies.
The Wet Wednesday H fleet is not in any way associated with the CHRF
program, and H Fleet handicaps are not transferable to the CHRF program.
H Fleet Rules
Fleet Membership Eligibility
Fleet Members must meet eligibility requirements
for Wet Wednesday Racing.
Fleet Members must have a signed entry form on
file for each regatta.
Fleet Members must certify that adequate liability
insurance for the boat is in effect at all times, and that they are
the named insured on the policy.
Boats new to the fleet must complete 3 qualifying
races before becoming eligible for trophies or for credit toward series
scoring regardless of whether or not they already have a CHRF handicap. Fun Series races do not count.
Boats that participated in the H Fleet the previous year
will continue with the handicap calculated based on the races from the prior year. Boats that did not compete the prior year must re-qualify.
About The Handicap Formula
by Bud Toye
The perfect method for handicapping vastly
dissimilar boats has been an elusive challenge for club racing programs.
Most (PHRF) are based solely on the design characteristics and potential
of the boat. Such rating systems assume the highest level of crew performance
and that the boat is fully rigged for racing.
The SBYC Handicap Racing formula attempts to
rate boats based on the totality of their performance taking into consideration
how they are sailed and how they are equipped. This creates a level playing
field that can accommodate dedicated racing boats and island cruisers in
the same race with neither at an advantage. In addition, the formula tracks
and adjusts for changes such as improved crew work and added racing equipment
such as spinnakers.
The formula is very simple, and all competitors
have access to the data on which the calculations are made, so there are
no secrets. After each race, the performance history of each boat is published
on the web, so competitors can follow their own track records. They can
verify the handicap calculations for any boat in the fleet.
The key to the formula is the ‘Wind Factor’,
and that's what makes it work. To synchronize the performances of all boats,
the conditions of the day must be part of the equation. This component
of the formula insures the continuity of valid ratings for all boats whether
they raced in a given race or not.
Each boat that races in a given race has its
elapsed time calculated and converted to seconds per mile. The distance
is based on the projected actual distance traveled. The distance to weather
marks are generally based on 1.4 times the point to point distance.
The mid boat finisher in the fleet (i.e. boat
6 in an 11 boat race) is used to calculate the Wind Factor. The wind
factor equals the mid boat handicap divided by the mid boat seconds per
mile. All boats participating in the race then have their seconds per mile
multiplied by the wind factor to arrive at ‘Adjusted Seconds Per Mile’.
The wind factor is an important component in
the handicapping calculations because it insures that boats participating
in high wind races don't unfairly have their handicaps lowered by the fast
conditions while the ratings of the non participating boats remain unchanged.
The same applies to participants in low wind races. It would not be fair
for a boat to gain a higher handicap just because there was little wind.
So the wind factor insures that ratings cannot be substantially affected
by the speed of the wind or other conditions of the day.
For each boat, the last five adjusted seconds
per mile are used in handicap calculations; values for the race just run,
and the last four races run by that boat. The largest value is discarded
and the remaining four are averaged; the resulting value is the boat's
handicap for the next race. That handicap will not change until the
boat races again.
An accurate Wind Factor in extremely light wind conditions cannot be achieved; therefore if the calculated Wind Factor is less than .6, the handicaps of all participants will not be recalculated and will remain the same until after the next race.
New boats entering the fleet will acquire an initital handicap after the first race. This rating will adjust quickly
based on its initial performance.
Trophies will be awarded pursuant to existing Wet Wednesday rules.
Season and series standings will be in accordance with existing Wet Wednesday
