NOTE; All dimensions are taken with the yacht fully rigged, and the pilot seated in the normal sailing position.
|

|
|
Ballast
The minimum weight of a fully rigged yacht is 50kg |
|
|
D BOOM
The boom shall be of round section metal tube of any diameter, having constant outer diameter and wall thickness.
The height of the boom above the ground is free. |
Boom
B1 The boom must be made of around section of straight metal tube(s)
B2. The lowest point of the boom must never be able to come below: 1/45cm from the ground
2/ eye level
Which ever is highest.
There must be a device to make it impossible to sheet any part of the boom below this level. A note on the minimum distance between the lowest point on the boom and the yacht is to be made for future checking and the position at which the measurement is made is marked on the yacht and the boom. |
Boom
B1 The boom shall be made of round section metal tube of any diameter. The outer diameter and wall thickness shall be constant over its full length.
B2 The yacht shall be equipped with a device that makes it impossible to sheet any part of the boom lower than the level of the pilot’s eyes in the normal sailing position or any less than 450mm from the ground, which ever is higher. The scrutineer shall measure and record the minimum distance from the boom vertically to the yacht and mark the position of measuring on the yacht, This is to provide a check so changes cannot be made later. |

M3 The mast must be rigidly supported by an arrangement of metal tubes, all no higher than 1.2m above ground level.
M4 The position of the mast should not be modifiable with the yacht in motion.
M5 The length of the mast shall be such that the distance from the top of the mast to its foot plus the distance from the mast foot to the ground do not exceed 5.5m |
Mast
M1 The mast must be a round section of metal tube, the outer diameter of which must not exceed 60mm.
M2 The mast may be made from a maximum of four different diameter tubes, each tube must have a constant outer diameter and wall thickness over its full length.
M3 The mast may have any kind of fixed internal stiffeners.
M4 The mast should be rigidly supported by an arrangement of metal tubes, all no higher than 1.2m above ground level, the yacht being fully rigged on firm flat ground with the competing pilot sitting in the yacht seat. The section of the tube should be as C4. This arrangement of tubes shall hold the mast rigidly at this point so it is unable to rotate or move in any other way relative to the chassis.
M5 The position of the mast should not be modifiable with the yacht in motion.
M6 The length of the mast shall be such that the distance from the top of the mast to its foot plus the distance from the mast foot to the ground do not exceed 5.5m. This measured with the yacht fully rigged on firm flat surface with the competing pilot sitting in the yacht. If a mast crane or other device which projects above the mast is used to attaché the sail at the head, it shall be considered a part of the mast in measuring mast length.
M7 When the mast is not is use in must be straight.
M8 At each change of diameter, 30mm are free to allow for chamfering of for protection of the mast pocket. An end of tube not exceeding 305mm (12”) in length may be reduced in outside dimension to facilitate a telescoping joint between mast sections.

E. SAIL
1. AREA, The maximum profile area of the sail (including the mast and boom pockets) shall be 5.0 square metres, as measured fully rigged and fitted to the mast and boom.
2. AERODYNAMICS, Stiffeners, fairings or similar devices fitted to the sail or pockets are forbidden.
3. POCKETS,
a) The sail shall be located on the mast by means of one pocket in the luff (mast), having an internal circumference of not more than 240 mm (120 mm when laid flat).
