RATING COMMITTEE (TYC)
LAKE TAHOE
CONSTITUTION, BY-LAWS & CLASS RULES
Last
modified March 18, 2000
Purpose:
To establish an independent, unbiased committee, under U.S. PHRF
sanction, that will evaluate and establish performance ratings for
yachts sailing in events and regattas sponsored by the Tahoe Yacht
Club and other sailing events using PHRF ratings.
Evaluation and
rating will be carried out as may be deemed necessary by the PHRF
Rating Committee or upon request of the TYC Race Committee Chairman,
PHRF Chairman, or upon petition from a member yacht owner for review
and modification of his or another yacht's rating.
Membership:
The PHRF Committee shall be comprised of five to seven members
who either by their knowledge and experience are qualified, or are
qualified to represent different divisions of the PHRF fleet. Members
shall be appointed by the PHRF Chairman to fill the categories
appropriate to be representative of the fleet. The Trans-Tahoe Race
Chairman may be asked to sit in an advisory capacity (non-voting).
Committee members may be removed by a two-thirds vote at any scheduled
meeting of the PHRF Committee. The Chairman may appoint a Marine
Industry Representative (MIR) to serve as a rater in order to expand
the knowledge base of the PHR Committee, membership in TYC is not
required.
Sanctioned
Events:
All sailing events sanctioned, sponsored, or associated with races
by T.Y.C. shall be governed and scored by the Lake Tahoe Sailing
Fleet (TYC) PHRF systems and ratings as adopted, as well as any
other events sailed on Lake Tahoe requiring PHRF sanction and ratings.
I. Class
Rules & Requirements:
A) PHRF handicaps
on Lake Tahoe, are for use inner-club and inter-club racing, Class
events, Trans-Tahoe, national events, and are available for "cruising/racing"
auxiliary sail yachts.
B) Yachts
must be self-righting mono hulls (Ref. ORC Special Regs. 1. I
& 5.2) of at least 20 feet in length ( LOA).
C) Unless
class rules, club rules, or requirements for a race specify otherwise,
each yacht is expected to meet the minimum accommodation and equipment
requirements as specified in the Offshore Racing Council (ORC)
Special Regulations Governing Minimum Equipment and Accommodation
Standards, applicable race rules, and State. and Federal regulations.
II. Handicaps:
A) Handicaps
in seconds (3) per nautical mile are assigned to each boat, and
represent a "base rating" with "adjustments". Standards and requirements
are:
1.Standard
hull, interior, keel, rig, as originally designed and built.
2.All sails
shall be cut in accordance with the latest IYRU, or class rules;
this includes girths on mainsails, head sails, and spinnakers/asymmetricals,
the number, placement and length of battens (except as provided
in the following sentence), and headboard restrictions. Full-length
battens are permitted without restriction.
3. Jib overlap
(LP) no greater than 155% of the fore triangle base (j).
4. Spinnaker
pole length (SPL) no longer than J.
5. Spinnaker
maximum width (SMW) no greater than 180% of SPL.
6. Spinnaker
luff (SL) no greater than 95% x the sq. root of I Sq. + J Sq.
7. A folding
prop, a prop solid in an aperture or a retractable outboard
8. A handicap
may be assigned to a yacht, which does not conform to all of the
above assumptions but does meet sail plan and hull requirements
of a recognized one-design class.
B) Ratings
can be changed at any meeting of the handicapper’s council,
by a majority vote of the handicappers present. Any member of
the Lake Tahoe PHRF Fleet may appeal the base rating of any boat
in writing. Such appeals, when accompanied by supporting evidence
will be considered at the first subsequent meeting of the PHRF
committee and may be determined by standard procedures or postponed
for further investigation at the committee's discretion. A member
may appeal his own rating in writing to the PHRF committee chairman
on the standard PHRF appeals forms after having competed for one
season under his assigned rating. U.S Sailing PHRF procedures
and fees will be followed for any appeal.
C) Adjustments:
Penalties or Credits, in seconds (3) per nautical mile, are applied
to the base ratings for variations or modifications to standard
boats. Specifically but not limited to:
1. Modifications:
AU modifications to hull, keel and rudder are handled on a case
by case basis. Owners must report all such modifications to the
chief handicapper prior to racing in any event. Disqualification
from a race and from future races may be assessed by the PHRF
committee for non-compliance. Lake Tahoe PHRF generally assumes
that all modifications are made to increase boat speed. Penalties
or credits are in three sec./mile increments.
2. When modifications
become too extensive, Lake Tahoe PHRF may declare that the boat
is a new class and will establish a new base rating different
from the boat's original class.
3) A new design
or previously un-rated boat may enter one of two possible PHRF
venues:
- an initial
provisional rating or
- base
rating
If the Owner
does not request a provisional rating in writing, he or she will
be assigned a base rating. Base/provisional ratings will be established
by the average of six predetermined venues. These venues will have
similar sailing characteristics to those of Lake Tahoe and will
be determined by the PHRF Committee. Should a boat not have adequate
data in the chosen six venues, it will be subject to the provisional
rating process discussed below. All boats having current Tahoe PHRF
base ratings will continue with those ratings unless modified by
the PHRF Committee. If an owner elects to enter Tahoe sailing competition
under a provisional rating, he or she will be assigned a provisional
rating under the above methods and will sail with this rating for
one complete series (spring or summer). Upon completion of the first
full series of racing, Tahoe PHRF Committee will meet and review
and evaluate this boat's sailing performance during the series.
At this time an owner may present to the PHR committee data and
may be asked for testimony relating to the boat's performance and
current rating. The PHRF Committee, based on observed performance
of a particular boat and any other pertinent information, may or
may not change the rating at this time and the boat will be required
to sail an additional full series under the existing rating. Upon
the completion of the second full series (spring or summer) of racing,
The Tahoe PHRF Committee will assign the boat in question, a base
rating. This rating will be determined by the PHRF Committee's observations
of performance. At this time, the owner may again present documentation
and testimony in order to provide data that may influence the decision
of the PHRF Committee.
4) At any time
an owner/Tahoe PHRF member may petition the PHRF Committee to modify
the rating of his or her boat. This should be in the form of a written
letter to The Chair of the PHRF Committee in which he/she outlines
the justification, including supporting data for a requested review.
The PHRF Committee will consider all such requests and will make
a positive or negative decision regarding the petition. The owner
of the boat will be notified in writing by the Chair of the PHRF
Committee as to the Committee's decision. If the PHRF Committee
determines to change the rating, the protocol for the establishment
of a provisional rating will be applied as discussed above and the
owner will be notified in writing by the Chairman.
5) If a boat
owner makes any modifications to his/her boat that could potentially
impact the sailing performance of the boat, the owner must notify
(prior to the next opportunity to race) in writing, the chairman
of Tahoe PHRF Committee as to the precise nature an specifications
of such modifications. This matter will be brought before the PHRF
Committee and this body will rule on effects of any modifications
and will change a rating as they may deem appropriate (see Sec.II;
1-8, & Sec. IV; A-D). This process will require a provisional
rating as described above.
III. Sail
and Rig Limitations:
Normally, US Sailing, IMS, PHRF, and specific class rules limitations
and restrictions apply regarding sails, methods of trimming, etc.
unless specifically indicated in the sailing instructions of the
event. The PHRF committee reserves the right to evaluate new developments
and to adjust ratings as may be indicated.
IV. Rig and
Sail Verification:
Since ratings are based on " standard rigs and sails," the verification
of rig and sail dimensions by physical measurement is considered
to be necessary to assure the uniform application of handicaps.
Lake Tahoe PHRF
Fleet may accept the following as verification:
1. Any current
or still accurate measurement rating certificate, such as IMS, IOR,
MORC, or other acceptable to the PHRF committee.
2. Physical
measurement by the chief handicapper or other designated fleet handicapper.
3. Physical
measurement certified in writing as accurate by the owner.
Changes must
be reported to the Chief Handicapper. If hulls, sails or rigs are
protested through normal procedures, PHRF reserves the right to
require actual measurement by a fleet handicapper. Disqualification
or other penalties may result from non-reported changes or modifications
to a yacht.
V. Penalties
& Credits:
The following are the standard guidelines used by the committee
for assessing penalties or credits. However, the committee will
use its discretion in assessing the effect of changes to any yacht.
A. Head sails:
LP up to 155% "J": No Penalty
LP over 155%
"J": - 6 sec.
(Includes
Blooper)
B. Mainsails:

if used in addition to std. spinnaker: -6 sec.
VI. Base
Ratings:
The rating committee may choose to establish a base rating of a
yacht using current U.S. Sailing PHRF, from venues selected by the
Committee whose conditions are similar to Tahoe and may determine
to modify these ratings based on performance that is observed while
competing on Lake Tahoe.
The rating committee
may choose to look at the types of race courses most predominantly
set in determining a base rating.
Only one rating
for all events shall be used for each boat or one-design class.
Lake Tahoe PHRF Fleet will establish and maintain Lake Tahoe PHRF
ratings and annually report these to U.S. sailing PHRF for publication
in the PHRF Handicaps Manual.
VII. Fees:
The committee shall establish reasonable fees for membership and
PHRF certificates.
VIII. Exceptions:
PHRF ratings are intended to provide equitable time allowances for
yachts of different designs and balance fleet competition. Not withstanding
the committee reserves the right to declare any yacht " exceptional"
and adjust its rating accordingly.
