2008 YACHT HANDICAPPING
SYSTEM AND RACE MANAGEMENT STRATEGY
HANDICAPPING
The basis for production of handicaps for the 2008 season is the RYA
Portsmouth Yardstick Scheme. Where possible, primary yardsticks, secondary
yardsticks and trial numbers have been derived from the 2006 data from the
RYA scheme. Significant use has also been made of the Byron software
calculator listings, for cases where RYA data is not available. In certain
cases, trial numbers have been allocated based on data from other sailing
associations. In some extreme cases, a trial handicap number has been sought
based on those for similar yachts.
The
handicaps have been derived in an attempt to produce a fair and transparent
estimation of a vessels handicap whilst maintaining a spirit of competition
and full participation amongst club members. It is important that the
proposed handicaps and strategy to monitor and update handicaps is agreed by
all competitors before the season commences thus minimising conflicts and
misunderstandings during the season.
Allowances form Base Yacht Configuration
1 Engine/Propeller Configuration
OB = Outboard
IBF = Inboard folding
IB2 = Inboard 2 bladed fixed
IB3 = Inboard 3 bladed fixed
The base handicap reference will be modified according to the following
arrangements:
OB modified to IBF +1% (1% = + 10 or 0.6 minute/hour)
OB modified to IB2 +2% (2% = + 20 or 1.2 minute/hour)
OB modified to IB3 +4% (4% = + 40 or 2.4 minute/hour)
IBF modified to ob -1%
IBF modified to IB2 +1%
IBF modified to IB3 +3%
IB2 modified to OB -2%
IB2 modified to IBF -1%
IB2 modified to IB3 +2%
IB3 modified to OB -4%
IB3 modified to IBF -3%
IB3 modified to IB2 -2%
2 Head
sail configuration
Head sail smaller than base configuration -2%
Headsail larger than base configuration +2%
(This does not apply to headsails which are reefed or changed to match
prevailing sailing conditions)
3 Keel
Configurations
If base handicap is for a yacht with a fin keel but has bilge or shoal keel
the following allowances will be made:
Fin to bilge + 20
Fin to shoal fin +10
If base
handicap is for a yacht with a bilge keel but has fin keel the following
allowances will be made:
Bilge to fin -20
Bilge to shoal fin -10
Race Specific Allowances
1 Use of spinnakers:
The base handicap assumes use of symmetrical spinnaker.
Yachts
not using the above will receive a concession in handicap of + 2.4 minutes/
hour i.e. +40
Yachts
using a non symmetrical spinnaker, not poled out, will receive a concession
of + 1.2 min/hr i.e. +20.
2 Crew
Size
An allowance of +20 will be made if the vessel is crewed by a couple or if
sailed single handed.
The +20
is based on one manoeuvre per 20 minutes which takes 20 seconds longer than
a full sized crew. This rule has been included to encourage full
participation of as many yachts as possible.
Number changes as a result of races completed during the
season
PY and SY
vessels will not normally have their numbers changed as these are based on
well attested results.
Vessels with TN status will be modified throughout the course of the season
based on actual race results.
Numbers will be modified in accordance with the Portsmouth yardstick system,
see sailors guide to Portsmouth yard stick..
Number
changes will be posted with race results for club members to view

Appendix
CONDUCT OF RACES
All
participating vessels must be WSBA members and must sign the WSBA pre season
disclaimer
A pre-
race brief will be held outside the marina facilities building before the
start of each race. The brief will include:
Listing
of participating vessels
Collection of entry fee
Course
details
Target
race start time
Lock out
arrangements
Remainder
of safety requirements
Working
VHF channel for the race
Declaration of spinnakers and crew size.
The
race buoys will be laid and recovered by volunteers from the Sea Cadets if
prevailing conditions allow. Otherwise volunteers from the race fleet will
be sought on a rota basis to lay and recover buoys. This is often the
bug-bare of organising the race and if crews are willing to race they must
be willing to take a turn in handling buoys. The basis will be that a
vessels expected to finish the race early will lay the buoys and the slower
vessels will recover buoys. A contribution from the entry fee will be given
to the sea cadets to pay for the fuel used.
The
race fleet should look to use the sea lock economically. I.e. get the whole
race fleet out in as few locks as is reasonably practicable. This will help
to consistently meet the agreed start time.
In the
interests of meeting the agreed start time, skippers should proceed to the
muster area on the start side of the start line as soon as possible after
locking out.
The starting procedure will be:
At
T-10 min all engines must be switched off (to be notified via the working
VHF channel)
A
count down at 5 min, 2min and 1 min will be announced on the working VHF
channel
The
final 10 seconds will be counted down on the working VHF channel
The T=
0 reference will be GPS time.
All
Vessels must complete the course as described in the pre race brief.
Each
competitor must declare their finishing time via the working VHF channel.
The finish is defined as the primary winches in transit with the finish
line. The finish time will be GPS time in hh:mm:ss format. As a back up the
crew should record their own finish time in case VHF communications fail.
Normal
rules of racing will apply
It is
hoped that all competitors conduct the race in a fair manner, however, any
protests should they occur should be immediately reported in writing to the
race secretary on completion of the race.
Every
attempt will be made to calculate and announce the results as soon after the
race as possible. This should be within a couple of hours of the declaration
of all finish times.
LEAGUE TABLE
It is
proposed to operate a league table throughout the season with points awarded
as follows:
1st
5 points
2nd
4 points
3rd
3 points
4th
2 point
5th
1 point
On
completion of the final race of the season, the 5 best results for each
vessel will be submitted and an overall season winner declared (i.e. the
vessel with the most points). A prize for the winner will be sought. In
addition a new trophy “The Jack Dickson Trophy” will be awarded to the
overall season winner.
If there
is a tie at the end of the season, a sail off will be arranged.
