Re: Radial mast Changes
I'm a little interested where John found his quote as it appears to have
lost quite a bit from the exact wording in the "Fundamental Rule" posted
on the ILCA website (see
http://www.laserinternational.org/rules/bylaw1.htm). But the basic idea
is right...
A Laser (or Radial or 4.7) is defined by the Laser Construction Manual,
The Class Rules specify that a "legal" Laser is one that is built by
"licensed builders" according to the Laser Construction Manual,
The Class Rules specify how we can rig and race the boat.
Bruce Kirby is the "owner" of the Laser trademark and he (or his
company) licenses "approved" (by ILCA and ISAF) builders to produce
boats in accordance with the Laser Construction Manual. There are
currently four licensed builders: Vanguard (North and Central America
and the Caribbean), Performance Sailcraft Australia (Australia + ?),
Performance Sailcraft Japan (Japan + ?), Performance Sailcraft Europe
(the entire rest of the world - thought I bet they don't sell many boats
in Antarctica). In addition, PSE sub-licenses a South American builder.
The Laser Construction Manual is (and should be to prevent counterfeits)
"confidential" and outside of Bruce Kirby and the builders there is only
a small circle of people, including some members of the ILCA World
Council (not me), who have access to it. This group can agree to modify
the Laser Construction Manual (and ask Ian Lineberger just how easy a
task it is to get just the builders to agree to anything!), the Class
Rules do not specify that the membership has to also approve those
changes. The LCM is "registered" with ISAF as a mechanism to make sure
there is a "golden" copy (ISAF "approval" enters through the Olympic
contract - but that is a different kettle of fish).
If we want to rig or sail our boats differently then we have to vote on
changes to the Class Rules.
This is the system that the Laser Class has operated under for 35 years
and it would be hard to argue that it has not been a wildly successful
model. I don't have it in front of me, but if you search the e-mail list
archives you can find a nice list somewhere of all the changes the Laser
has gone through over its 35 years, many of which were introduced
through changes in the LCM (and changes to the Radial sail - we are at
Mark VI now? - are recent examples).
The key principle is that changes introduced through the LCM do not make
existing boats obsolete (or existing boats can be modified in order to
make them "legal", like buying a Mark VI Radial sail when your Mark V
wears out). The testing done with the composite upper shows that, while
it appears to satisfy the goal of opening the weight range, it is not a
magic bullet. Nobody is strapping one on and suddenly catapulting
themselves to the front of the fleet.
But don't believe me! Go read this stuff yourself!! Read the class rules
at the link above, go to www.laserforum.org and read the threads on the
composite spar. The information is out there!
And, interestingly, you can still see some of the original motivation at
the ILCA website: http://www.laserinternational.org/lwedit.htm - scroll
down about half way to see a bit on the "carbon" spar.
Also, for those of you who are not ILCA-NA members (and if you live in
the North American Region you should be!), you can read Ned Jones Q&A on
the "carbon" spars in the Summer Laser Sailor by going to www.laser.org,
following the "news" tab, click on "The Laser Sailor" in the left column
and then download the pdf file (warning! it is quite large -don't do it
on a dialup connection!).
