Juniors 8.5m2 division: 8.5 Sq.m.; A maximum of 7 full width battens are permitted. The number of additional leach battens is free provided the length of each is not more than 25% of the distance from the leach to the luff along the centre line of the batten. A maximum of 3 cambers are permitted

 

Youth and seniors: 11.0 Sq.m.: A maximum of 7 full width battens are permitted. The number of additional leach battens is free provided the length of each is not more than 25% of the distance from the leach to the luff along the centre line of the batten. A maximum of 3 cambers are permitted

 

4.2 The sail shall carry the identification marks required by rule 2.6. Sailmakers marks shall not exceed 300mm in diameter.

 

4.3 All sail models will be measured in accordance with the following System by the Formula Experience Class approved sail measurer, prior to being placed on the approved list

 

4.4 The mast pocket shall extend downwards to within 300mm of the Tack Measurement Point or beyond. The width of the mast pocket is optional.

 

4.5 The Tack Measurement Point (point Y) shall be determined in one of two ways depending on the sail configuration:

 

(a) If the mast pocket extends downwards beyond the intersection or fair extension of the foot of the sail, point Y shall be the point on the forward edge of the mast pocket which is opposite to the point at which the foot or its extension intersects the rear edge of the mast pocket, measured perpendicular to the forward edge of the mast pocket.

 

(b) If the mast pocket is not as specified in (a), point Y shall be defined by the corner of the 90deg; template shown in the diagram. The template shall be placed so that when the 450mm arm is aligned with the leading edge of the mast pocket the foot of the sail shall touch the 250mm arm of the template and no point of the sail shall lie below the extension of the 250mm arm.

 

4.6 The Clew Measurement Point (point Z) shall be the point at which the foot or its extension intersects the leach or its extension.

 

4.7 The Head Measurement Point (point X) shall be the highest point on the forward edge of the mast pocket where the sail is 150mm wide, measured perpendicular to the forward edge of the mast pocket. The sail shall be made so that the head can be found in this way.

 

4.8 Headboards are prohibited.

 

4.9 A clewboard is permitted.

 

4.10 Battens and camber inducers shall not be removed for measurement.

 

4.11 The sail area shall be measured in accordance with the following method:

 

4.11.1 With sufficient tension applied between points X and Y, or as close as possible to those points, to remove all wrinkles perpendicular to the line between the points, the distance from X to Y shall be measured, to be the luff length, a.

 

4.11.2 With the tension maintained a straight chalk line shall be marked on the sail from point X to Y. With the tension removed, measurement d shall be the maximum perpendicular offset from the chalk line to the forward edge of the luff pocket, projected if necessary through local variations in shape.

 

4.11.3 With sufficient tension applied between points Z and Y, or as close as possible to those points, to remove all wrinkles perpendicular to the line between the points, the distance from Z and Y shall be measured, to be the foot length, c.

 

4.11.4 With the tension maintained a straight chalk line shall be marked on the sail from point Z to Y. With the tension removed, the area between the chalk line and the edge of the sail shall be measured by dividing it into trapeziums, triangles and segments and measuring the area of each. For the purpose of this instruction the area of a segment shall be taken as two thirds of the product of the chord of the round and the maximum perpendicular offset to the chord. This area shall be called the foot area.

 

4.11.5 With sufficient tension applied between points Z and X, or as close as possible to those points, to remove all wrinkles perpendicular to the line between the points, the distance from Z and X shall be measured, to be the leach length, b.

 

4.11.6 With tension maintained a straight chalk line shall be marked on the sail from point Z to X. The procedure described in rule 4.12.4 shall be used to measure the area between this chalk line and the edge of the sail, to be called the leach area.

 

4.11.7 The distance from point Z to the chalk line between points X and Y, measured perpendicular to the chalk line, shall be e.

 

4.11.8 The area of the sail shall be calculated

 

4.12 Multiple attachment positions may be fitted at the tack and clew.

 

5. Crew

 

The crew shall be one person.

All sails shall carry Class identification tags securely fixed at the clew cringle , all boards shall have EITHER a permanent unique serial number applied by the manufacturer, OR shall carry a Class identification tag securely fixed through a towing eye and serial numbers areas required by isaf registration system.

Registered skegs and foils shall carry a unique ID number on the head stock,

Equipment I.D.marks may be applied by the measurers during event registration. The limited equipment shall not be altered in any way during the regatta without the permission of the Jury. The Jury may only permit substitution of irreparably damaged limited equipment on a 'like for like' basis. Other equipment is interchangeable provided it complies with these rules.
