Holland would like to make the following changes and proposals to the rules:

11. SAILS

rule 11.2 will change accordingly:

All sails shall be of woven polyester with the exception of the No. 1 Genoa which may be a laminate consisting of a poyester film and a poyester or aramide scrim made of reinforcement fibers.

a new rule will be no. 11.25:

All sails shall be constructed using conventional panel construction........etc. (wording of old rule no. 11.2)

a new rule will be no. 11.35:

Genoa’s consisting aramide are allowed, only 1 genoa a calendar year (1/1 – 31/12) All existing mylar and Pentex genoa’s are grandfathered per accepting date of this rule.

11.6 Mainsail

a new rule will be no. 11.6.12:

PSA spreader patches of aramide with a min. of 15000 dpi and diam. of 25 cm are allowed.

11.7 Headsails

rule 11.7.1 has a error being headsail material shall only be as Rule 11.1 ( must be changes into Rule 11.2)

changes and proposals to rule 11.7.5:

11.7.5. No. 1 Genoa. Maximun LP (per ISAF measurement) 5170 mm, maximum luff lenght 11500 mm. Window allowed with a maximum area of 0.1 M2 but not placed nearer than 250 mm of any leech with the exception of a small telltalewindow, must have the following conditions:

Genoa made from aramide:

75% of the genoa must have a polyester taffeta on min. one side of the panels. Minimum amount of aramide allowed; 10.000 dpi Minimum thickness of film allowed; 1,5 mil. The remaining 25% is free. Sailmakers should certify 1,2 and 3.Certificate should be attached to the measurement certificate.

Genoa made from mylar or pentex:

75% of the genoa must have polyester fibres of minimum 18.000 dpi, with a minimum weight of 5.1 oz. 25% of the genoa must have polyester fibres of minimum 12.000 dpi, with a minimum weight of 4.5 oz. Minimum thickness of film allowed; 1,5 mil. Sailmakers should certify 1,2 and 3. Certificate should be attached to the measurement certificate. All existing mylar and pentex genoa’s are grandfathered.

a new rule will be no. 11.7.55:

PSA spreader and stanchion patches of aramide with a minimum of 15.000 dpi with maximum dimensions of 1000 x 300 mm. are allowed.

PSA kevlar patches have a far better point resistance than dacron, with almost no extra cost.

If the boards choice goes for kevlar, than even the mylar/pentex proposal is valid. When the kevlar proposal is unfortunally not accepted, than the proposal of the mylar/pentex will still replace the weightfigure of existing rule 11.7.5.

The proposed starting date is : 1th of January 2003.

Being Dutch we believe that this proposed Kevlar genoa is still cheaper then 2 or 3 Pentex genoa’s a year.

REPLACEMENT OF WIRE RUNING BACKSTAY AND CHECKSTAY BY ROPE RUNNERS:

As discussed on the last Int. meeting rope runners have an advantage over wire runners. Running backstay’s can break easily, without warning, because of metal fatique, which has happened to 2 X-99’s in Holland, with the effect of 2 masts going over the side. Wire running backstay’s and checkstay’s damaging the mainsail by smashing around at the leeside of the sail. 4 mm. 1x19 rvs wire has a breaking load of 1350 kg., 5 mm. 1x19 rvs wire has a breaking load of 2100 kg. and 6 mm. 1x19 rvs wire has a breaking load of 3000kg. We think that it is advisable that the breaking load of the running backstay is at least 10% less than the breaking load of the forestay, otherwise something else will break.

Some differences between dyna-one and vectra-one ( or similar ropes):

Dyna-one: 6 mm. has a breaking load of 2700 kg., is lighter and cheaper than vectra-one, but has creep. To our opinion that is not that important, because one day hard racing in topwind conditions will give you about 1 cm more rope. Adjusting the running backstay of an X-99 is more a question of feeling than mathematics. Vectra-one: 6 mm. has a breaking load of 2500 kg., is about 50% more expensive, has no creep but is a bit less resistance to UV light. Both can be allowed under the new rule.

Rule 9.1 will change accordingly:

9.1 Standing Rigging

All standard rigging shall be of 1x19 stainless steel wire with sizes and lenghts as defined in the sailplan, with exception of the running bakstays and check stays. Dyeform........etc.

9.45 Running Backstays are also allowed from rope with a minimum breaking load of 2300 kg and a maximum breaking load of 3000 kg. Checkstays are also allowed from rope with a minimum breaking load of 1200 kg. and a maximum breaking load of 1750 kg.

A running back- or checkstay from rope with an splice on both ends will have 10-15% less breaking load.

The proposed starting date is: 1th of January 2003.

About rule 7.4 of the constitutions:

We think that rule changes must be informed to the Int. secretary at least one week before the agenda will be dispatched ( 4 weeks for the AGM) to all members for the official International Meeting. An email from the secretary to the members reminding them to send agenda items and rule changes will be very helpfull.

The 2 months mentioned in rule 7.4 of the constitution are, with a meeting almost planned in the first days of November, too long because this means that it will be the end of August and most people will still be on holiday.

We have noticed that in the revision of the Class Rules just received by email Jens Kjaersgaard is still on the board for Danmark but he is replaced by Thomas Kiaer. Do you happen to have information about his addres and phone numbers etc.

The votes will be separately for: Kevlar genoa incl. new rule for mylar/pentex New rule for mylar/pentex Kevlar patches on Mainsail D) Kevlar patches on Genoa E) Runner back- and checkstay from rope F) Constitution

With kind regards,
