MISTRAL MOD WORLD CHAMPIONSHIPS 2004, CESME, TURKEY 

2004 OLYMPIC REGATTA
Response to Coaches Questions
Issue #2   2004-04-21  Correction to HULL WEIGHT

The questions put forward by the coaches to clarify outstanding points regarding measurement at the Olympic Regatta are welcomed. The following draft notes/interpretations/requirements are published here at the Championships to be as helpful as possible. The detailed wording may change later when the notes are published as official ISAF or IMCO documents.

The notes apply to the 2004 Olympic Regatta only. The existing Class Rules will govern all class events prior to the Olympics, unless modified by interpretations issued by IMCO with ISAF approval.

The questions are written in plain type, Responses in Bold.

RIGS.

A statement was earlier verbally communicated that the “board” refers to a complete Mistral One Design. Will as a result only Mistral One Design Equipment (complete set) manufactured after 2003, 1 Jan. be allowed in the Games.

It is intended that all Mistral equipment used at Athens 2004, with the exception of sails, should have been manufactured after 1 January 2003.

How can sails complying with point 1 be identified?

Sails are excluded from this ruling because the date of manufacture cannot be accurately identified. Sails presented for measurement at Athens will be compared with a known standard sail. Provided this comparison is acceptable to the measurer and there is no evidence that the sail has been altered it will be approved for use.

Can the official serial numbers of all equipment (boards, masts, daggerboard, fins) eligible for use in the 2004 Olympic Games be finalised and announce

The Serial Numbers of approved equipment is available on the IMCO website.

Will only the new boom be allowed or both versions?

Only the new boom will be permitted.

May the boom arms be glued and/or shimmed to the boom head. May screws be glued in. (it is general belief that this may prevent early boom failure due to play in the joint).

Preventative maintenance may be carried out at the boom head/arm joint to reduce the possibility of failure in use, provided this does not contravene Class Rule C.8.2.b by changing the strength or performance of the boom. For this reason gluing the joint or screws will be accepted but shimming will not.

 May the complete boom grip be replaced as a repair?  May the repair be made using different grip material?

The complete boom grip may be replaced by a new standard grip, but not by using a grip made of a different material.

HULL

Sanding

Please define “rubbing down”. For example is sanding allowed and to what extent?

The term “rubbed down and polished” as used in Rule C.6.3.d is interpreted as meaning light abrasive treatment to remove surface imperfections, following the original hull contours.

There seems to be some confusion about whether all hulls come out of the mould in exactly the same way. Specifically in this event the “bump” in front of the fin case has been open to scrutiny. Is there a standard measurement system (i.e. cross section of boards) or specification (measurement range) that will be used to determine whether a board is class legal?

For the Olympic Regatta it is intended to apply a Measurement Regulation in the following draft terms.

The transverse high area in many hulls situated approximately 475mm forward of the HDP may be sanded down to leave a minimum skin thickness of 0.25mm, provided this does not result in forming a hollow in this area. In cases of doubt the remaining skin thickness will be measured, which may involve making a small hole or cut in the hull surface”

Competitors should note that the original skin thickness in this area is approximately 0.5mm.

Hull Weight

Can lead under the mast track be removed to make the hull meet minimum weight and balance point?

There is no lead fitted under the mast track by the manufacturers. Information from B&M is that hulls are delivered within a weight band of 15.30 to 15.38 kg. Any extra weight that is required to bring a hull within this weight band consists of resin.  This resin cannot be removed, under Class Rule C.6.3 a and b.

Centreboard slot flushers

May slot flushers be glued in to avoid them from coming loose whilst racing?

The fit of slot flushers may be improved by re-positioning the fixing screws. Glue may be applied to the flushers as a precaution against them being dislodged whilst sailing. However fairing of the flushers is not permitted, and glue should not be used in a way that contravenes this rule. This rule will be strictly applied during measurement at Athens 2004.
