Committee 'Away Day' 2003The MROA Committee reports back from its annual 'think tank' - January 2003 |
|
Summary of points made during general discussion on weight reduction and weight distribution Orders
for new boats were dropping, whilst people waited to see what was happening
with regard to weight reduction and weight distribution.� Development should be encouraged, but changes which render a significant number of recent boats obsolete, or prohibitively expensive to modify, should be avoided.� So should developments that would put average-sized female crews at a disadvantage, or reduce the suitability of the boat for various waters. If we had more newer boats, then the Class would be in a better position to consider allowing weight reduction, as more boats (and sailors) would be able to take advantage of a Rule change. It
would be bad publicity for the Class if we built very light boats which were
prone to breaking up or sustaining major impact damage. The
second-hand market in Winder-built Canterbury Tales was developing.� This could be damaged by new boats being
built with the potential for greater weight reduction. There
were arguments against reducing the hull weight � particularly those that
suggested lighter hulls would make crew weight more critical. There
is no effective way of limiting correctors in a boat � builders would get round
this by building more weight into the middle of the boat. We
needed to develop some viable methods of controlling weight distribution.� Swing tests were thought to be a possible
solution. Knowledge
of swing tests was well known, but there were practical problems in testing
Merlins. It
was thought to be important to try swing tests before the March Committee
meeting in order to achieve solid data upon which to consider the next move. To
trial swing tests a site would have to be found soon and we should need to
decide who to invite.� It was suggested
that we invite an experienced measurer from another class with knowledge of
swing tests, together with Lawrie Smart and other representatives of the Merlin
Rocket Class to show openness.� From
Committee Pat Blake, Graham Williamson, Will Rainey, Andy Jones and Dan Alsop
would be invited to attend. We
should wish to test one recent boat from each of Winders, Lawrie Smart and
Linton Jenkins, together with at least one older boat, including an NSM
II.� All boats tested should be down to
weight. A sub-committee was formed to arrange the tests � Pat Blake, Will Rainey, Graham Williamson and Andy Jones. It was suggested that we should put some frequently asked questions (FAQs) on the Forum, together with Committee�s comments, regarding weight and other �hot� issues.� This would be a good way of keeping the Membership in touch with current thinking on Committee. Publicity � thoughts on 2003 Will
Rainey produced some thoughts on publicity options for 2003.� These are on a separate page and action
could be� considered at the next
Committee meeting. 1.
MINIMUM WEIGHT Committee do not intend to introduce a proposal to
reduce the minimum hull weight at present.�
They are not in favour of reducing the weight until there is a
significant number of boats in existence which are capable of making the
change, which they believe will not happen for another 4-5 years.�
We
believe that reductions in minimum weight will happen at some time in the
future, but think that this will be determined by the circumstances at the
time.
2.
WEIGHT DISTRIBUTION Committee have a concern about extremes of weight distribution around the boat - both the technical and financial impact of going to extremes.� In the interests of informing opinion we propose to get some practical tests done with the help of the RYA for consideration at the next committee meeting.� This will put us in the position, if necessary, to propose an amendment to the Measurement Rules for consideration at this year�s AGM. To
facilitate some practical tests a small sub-committee will be set up together
with the RYA for tests to be done and results established before the 12th
March. 3.
WING RUDDERS Graham
Williamson expressed concern that wing rudders might bring about radical
changes in the development of hull design.�
He had contacted Ken Kershaw of the RYA, who had said that other classes
had similar concerns.� Graham wanted to
flag up to the Class that committee proposed to introduce a Measurement Rule
amendment at this year�s AGM to ban wings on rudders.� Advice from the RYA would be taken regarding the wording of the
new Rule.� Committee agreed that an
article stating this intention should be published in the next magazine. |
