Whilst we're getting into the realms of Class and Association Rules I would like to point out that if you intend to travel to Zandvoort be sure to take a saw with you.
At present the length of your spinnaker pole mustn't exceed 3,500mm and project further than 800mm past your bows. Most modern F16's that I have seen flaunt this rule including the Blade. So unless this 800mm measurement rule is retracted then there will be a lot of unhappy sailors cutting their poles and altering their stays to meet the required measurement.
Now that would be a great start to an event.

1.10 The gennaker boom (also referred to as a spinnaker pole) 1.10.1 The length of the gennaker boom shall not be more than 3,50 metre.
1.10.2 When the aft end of the gennaker boom is located in front of the vertical passing through the leading edge of an unrotated mast, than the distance between the fixing point and the leading edge of the mast is considered to be part of the gennaker boom.
1.10.3 In contrast to ISAF rule 64.2, the gennaker boom may be fixed to the forward beam.
1.10.4 The gennaker boom shall be fixed and sit approximately on the longitudinal centreline of the boat.
