| These
rules are taken from current European class 5 rules, I will try to
note if these rules differ from my most current PAC
Rim rules.
CLASS 5 SPECIFICATIONS:
BALLAST
The minimum weight of the fully rigged yacht is 50 kg.
BOOM
B1. The boom must be made of round section straight metal tube(s).
(The
PAC Rim rules specifically remove the 's' in "tube(s)" and add that the
boom shall be of a constant OD and wall thickness over its length)
B2. The lowest point of the boom must never be able to come below
45 cm from the ground or pilot's eye level whichever is highest.
There must be a device to make it impossible to sheet any part of the
boom below
this level. A note of the minimum distance between the lowest point
of the boom and the yacht is made for future checking and the position at
which the measurement was made is marked on the yacht and the boom. (PAC
Rim rules note that all measurements are made with the pilot and
any ballast on board)
CHASSIS
C1. The width of the yacht should not exceed 2.00m.
(PAC Rules mention rolling loaded the yacht through upright posts 2.0m
apart)
C2. The wheelbase of the yacht must not exceed 2.50 m.
C3. The chassis must be made of metal tubes, the section of which must
be round, square or rectangular. (Several French
boats use seriously ovalized tubes and no one seems to be complaining?)
Cables are forbidden, except for the steering.
C4. Fairings are forbidden on the chassis. Inside and outside wheel
covers are allowed.
C5. Any rear wheel with wire spokes must be covered by internal and external
wheel covers.
MAST
M1. The mast must be made of round section metal tube, the outer diameter
of which must not exceed 60 mm. At rest, the mast must be straight.
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. At each change of diameter, 3 cm are free to allow
for chamfering or for protection of the mast pocket. (PAC
Rim rules state that "The mast may have any kind of fixed internal stiffeners.")
M3. The mast must be rigidly supported by an arrangement of metal tubes,
all not higher than 1.20 m above ground level. (mast hound)
M4. The position of the mast must 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 shall not exceed 5.50m
.
SAIL
S1. The maximum profile area of the sail shall be 5.50 m2
. (As soon as I can find a good way to reproduce
it, I will will include a sail measuring diagram.)
S2. The sail must be located onto the mast by means of a pocket.
S3. The internal circumference of the mast pocket must not exceed 240
mm (i.e. 120 mm long {wide?} when laid flat).
S4. The sail must be free to rotate around the mast.
S5. The mast pocket must be made of sailcloth. Stiffeners, fairings
or similar devices
fitted inside or outside the mast pocket are prohibited.
S6. Fairings or similar devices fitted to the sail are prohibited.
S7. The sail may be modified by a device as follows :
1. Cunningham hole
2. Foot tensioner
3. Kicking strap
4. Batten tensioner line or leach line.
S8. The maximum width of the battens is 50 mm
S9. (PAC Rim only, "With the competing pilot
sitting in the normal sailing position and the sail pulled in, the pilot
must have good all-around visibility.")
SEAT AND FOOTREST
SF1. The yacht must have a backrest and side-restraint for the pilot
(and a passenger if yacht is two-place) and a footrest. These accessories
may be part of the seat. The seat may not contribute to the rigidity or
the resistance of the chassis.
SF2. The foot-rest should prevent the pilots (and passengers) feet
inadvertently touching the ground.
SF3. The external width of the seat may not be over 1.00 M.
SF4. The external length of the seat may not be over 2.50 M.
SF5. The front of the seat or footrest may not be further forward than
the back of the mast.
SF6. Fairings that form part of the seat and extend no further than
the limits of the seat are permissible. The shape of the seat must be such
that the pilot's body is always fully exposed when viewed directly from
above.
SF7. It shall not be possible to move the seat while the yacht is in
motion.
SF8. Any sharp edges on the yacht must be made safe.
(PAC Rim rules and USA rules require seat belts
if local authorities specify them.)
(PAC Rim rules specify wheel and tire shall nor
exceed 650 mm) (Europeans are discussing this and I have heard of 630 mm
being used as a limit.)
Specific FED
5 Rules as soon as I get them. Basically, don't change stuff.
