The maximum length of the mast, measured from the fair deckline shall not exceed 6250mm

At any cross section normal to the mast's axis, the mast shall be circular and of uniform wall thickness. The bending curve shall be equal in every direction. A tapered mast is allowed. Pre-bent masts are prohibited.The bend curve shall be checked as follows: support the mast 50mm from each end, suspend a weight of approximately 20kg at 1700mm from the base and measure the deflection from the horizontal. Rotate the mast through 90°, 180° and 270° on the longitudinal axis and repeat the test. There shall be not more than 10% difference in any of the deflections and the deflection shall not exceed 100 mm when not under load.

ADD 4.3 At International. Continental or World Championships the sails Shall be restricted to those from ISAF licensed sailmakers only. For this restriction to apply it SHALL be specifically included in the Notices of Race . The List of currently licensed sailmakers will be posted on the official FW Class Website .

All registered sail models will be measured in accordance with the following System by the The FW Class approved sail measurer , prior to being placed on the approved list

4.4 The number and length of battens is optional.

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

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

(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 90° 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.

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

4.8 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.

4.9 Headboards are prohibited.

4.10 A clewboard is permitted.

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

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

4.12.1 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.

4.12.2 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.

4.12.3 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.

4.12.4 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.

4.12.5 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.

4.12.6 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.

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

4.12.8 The area of the sail shall be calculated

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

5. Crew

The crew shall be one person.

Registered skegs shall carry a unique ID number on the head stock, his 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.
