Nye regler for
køllehodestørrelse og
køllelengder
Utviklingen på
køllefronten går sin gang.
Regelverket bestemmer hva
som er lov. Nå har United
States Golf Association
sendt et brev til
produsentene om
begrensninger på størrelsen
på køllehoder og lengden på
kølleskaft - bortsett fra
puttere. I korthet går
forslagene ut på ikke mer
enn 460 kubicentimers
hoder og ikke lengre enn 48
tommers skaft.
Golfsiden har fått tak i
brevet.
Her er ordlyden:

Notice To Manufacturers
on Head Size and Club Length
Limits
In December of 2001 the USGA
proposed limits on clubhead
volume and club
length. The clubhead volume
limit proposal was modified
in January
2002. This Notice is to
advise manufacturers of an
addition to the
clubhead size proposal, a
revision to the club length
proposal, and
proposed implementation
dates for these changes to
the Rules.
Clubhead Size for
Wood-type Clubs
The USGA has previously
proposed a clubhead volume
limit of 460 cc plus
10 cc for measurement
tolerance. We have received
many comments
regarding that proposal. In
addition to the previously
made volume
proposal, the USGA is now
proposing that clubhead heel
to toe length and
clubhead sole to crown
height will also be limited.
The USGA believes
that the use of both volume
and dimensional controls
will define the
size limitations more
effectively than either
volume or dimensions
alone. Clubs will be
required to conform to both
volume and dimensional
limits to be considered
conforming.
Clubhead dimensions will be
measured with the head
positioned at a 60
degree lie angle. If the
outermost point of the heel
is not clearly
defined, it will be deemed
to be 0.875 inches above the
horizontal plane
on which the club is lying.
The proposed limit for
clubhead heel to toe
length is 5.0 inches. The
proposed limit for sole to
crown clubhead
height is 2.8 inches. Both
dimensional limits include
an allowance for
measurement tolerance. The
method used to measure
clubhead length and
height is illustrated in the
attached drawing.
Based on clubs already
submitted to the USGA, all
clubheads measuring
less than 460 cc + 10 cc in
volume have length and
height dimensions
which are less than the
proposed limits.
Club Length
The USGA has previously
proposed a club length limit
of 47 inches for
clubs other than putters. We
have received many comments
regarding that
proposal. The USGA is now
proposing to increase the
club length limit
for clubs other than putters
to 48 inches. The
measurement method is to
be made with the club in a
60-degree lie angle position
from the ground
plane to the end of the
grip. This measurement
method is illustrated in
the attached drawing.
Proposed Timetable
The USGA proposes that these
rules for clubhead size and
club length
limit become effective at
the next quadrennial
publication of the Rules
of Golf, which is January 1,
2004. However, in
recognition of the fact
that some clubs exceeding
these limits are already in
use, a one-year
grace period is being
proposed for those clubs,
permitting their use
until December 31, 2004.
------------------------------------------------------------------------
Written comments regarding
the proposed changes to the
head size limits
and club length limits as
well as the measurement
methods for both
should be sent to the USGA,

14, 2003 will not be
considered.
