Equipment
C.2.1.
LIMITATIONS
(a)
The specified and permitted fittings and equipment of the TASAR may,
having regard to the circumstances of supply in the country of any approved
builder, and without the prior approval of the World Council, be substituted
by the builder or owner, with fittings and equipment of the same or
substantially the same size, quality and construction as those specified,
provided such substitution does not affect the performance of the boat.
Each Region's nominee to the Chief Measurer's Committee and all
District Measurers shall be entitled to complete information about all such
substitutions by the builder, and the reasons why they were incorporated.
(b)
No fittings, wedges, accessories, or other attachments other than
those originally supplied by the builder may be affixed to any part of the boat,
and no function may be added or extended, except as permitted by C.2.2 -
C.2.5
(c)
No part of a boat shall be replaced during an event, except
for the use of one alternative jib which has been measured as provided for
in G.1.2., other than to replace equipment damaged beyond repair before the
next race. Such replacement may
be made only with the approval of the Race Committee, and no re-substitution
of the original equipment may then be made, except with the approval of the
Race Committee.
(d)
Standing rigging shall not
be adjusted when racing, except that shroud tension may be adjusted using shroud sliders.
(e)
No holes may be made in the hull or deck mouldings, except for the
purpose of making repairs – see C2.5
C.2.2.
OPTIONAL
(a)
Wind indicators may be attached.
(b)
Additional tufts or ribbons may be attached.
(c)
Wedges may be used under the boom vang clam cleats.
(d)
Packing may be used under the jib fairleads providing that the
measurement from the deck to the underside of the top of the fairlead does
not exceed 40 mm.
(e)
Additional threaded inspection ports with openings not exceeding
6" may be installed in the deck or cockpit if required for hull
repairs, or for mounting of compasses.
(f)
Storage is permitted in the cockpit; ties or bags may be used.
(g)
A maximum of two compasses may be mounted as desired.
(h)
Any additional equipment required by an international, national, or
other governing authority for safety purposes may be fitted or carried,
provided it is not used in contravention of A.1.2 (e.g. Reefing capability)
required for training safety may not be used for class racing.
(i)
A jib tack downhaul cleat may be attached to the luff of the jib.
(j)
Small fixed shackles may be carried in the clew board of the jib, and
a snap shackle may be attached to the jib sheets.
(k)
A simple line and block purchase system with a mechanical advantage
of two may be affixed to each shroud slide to assist movement of the slide. A
turning block which does not increase the mechanical advantage may be added
immediately aft of the track. With the slide fully forward and the
line fully extended aft, the distance from the aft end of the track to the
bearing point of the pull back handle shall not exceed 150 mm.
(l)
One small fairlead for the outhaul line may be mounted on top of the
boom.
(m)
The surface of the mast rotation lever may be taped or otherwise
treated to improve grip.
(n)
A restrictor device for holding the daggerboard forward and vertical
may be used provided it is made of material sufficiently resilient to permit
the tip of the daggerboard to rotate aft under impact load, e.g. sponge
rubber, styrofoam, etc.; and further that it does not extend forward of the
aft edge of the daggerboard. No
non-resilient material may be incorporated in the restrictor or used as
fairing. The padding allowed by C.4.3 may be compressed
or removed where the restrictor is fitted in the centrecase.
C.2.3.
MODIFICATIONS
(a)
The tiller and tiller extension are not restricted in any way except
that the tiller shall be capable of insertion into and removal from the
rudder head. Such insertion and
removal shall not require the use of tools, screw devices, or excessive
force.
(b)
The rudder downhaul line may include shock cord.
An uphaul device, with a cleat on the tiller, may be added
(c)
The hull, daggerboard and rudder blade may be
sanded, painted and polished.
(d)
The mainsheet shall be rigged with either 4 or 5 parts active. The mainsheet strop length shall be not less than 240 mm,
measured bearing point to bearing point, and may be substituted with line.
The strop
shall not be adjustable in length. The strop may be fitted above or below
the mainsheet block system.
(e)
The traveler control line shall be rigged with 2 parts active, but
additional blocks may be fitted to make 3 parts active.
Additional blocks or fair leads may be added to position the traveler
control line as desired. A
retraction device for the traveler control lines may be fitted.
(f)
The downhaul control
line shall be rigged with 2, 3 or 4 parts active.
One or two blocks may be attached to the "Cunningham"
cringle of the mainsail and one block may be attached to the mast below the

of any size.

Fittings for stowing the whisker pole on the boom may
be added.
C.2.5.
REPAIRS
In the event of damage to any part
of a boat, necessary repairs may
be made provided repairs are made in such a way that the essential shape,
construction detail or other characteristics are not materially affected.
Fittings shall be attached in the same position as before the repair, or as
close as is structurally possible.
C.3
Buoyancy
C.3.1.
Reasonable watertight integrity of the hull must be maintained at all
times.

to permit removal, there must be a permanently watertight component behind
the port mounting ring.
C.3.3
Any compass which is recessed into the deck shall be permanently
installed with fastenings and a sealant.
C.4
Location of Hull Appendages
C.4.1.
A rope handle may be attached through holes drilled through the top
of the daggerboard.
C.4.2
A line or shock cord may be tied or hooked through the rope handle or
holes in the top of the daggerboard, and attached to prevent loss in the
event of a capsize. A hole may
be drilled in the top of the daggerboard case for the purpose of receiving
such line or shock cord.
C.4.3

may be varied to provide an optimum friction fit for the daggerboard, but it
shall be of substantially uniform thickness for the length of the centrecase.
C.5
Crew
C.5.1.
It is the intent of these class rules that the same two people
should be able to sail together throughout an event without disadvantage.
Subject to C.6, a minimum of two persons shall race the TASAR, but
nothing shall prevent three or more persons from racing, provided
that the same number of persons sail together for the entire event.
Nothing shall prohibit a change of helmsman during a race, nor a
change of forward hand during an event,
subject to the helmsman accepting the onus of proving that no systematic
attempt has been made to sail with heavy crews in heavy weather and light
crews in light weather.
C.6.1
The TASAR, while racing in all sanctioned events, shall carry
a minimum total crew weight of 130 kg.
The crew shall be dressed in shirts and shorts, swim-wear or the
equivalent, without shoes, all dry, at weight-in.
C.6.2
In the event that the weight of the crew, thus weighed, shall be less
than 130 kg, such crew may race the TASAR, provided that, throughout the
event, ballast equal in weight to at least the difference between the crew
weight and 130 kg is carried secured in the cockpit.
The ballast carried need not exceed 12 kg.
C.6.3
At sanctioned events, the Race Committee shall weigh and record the
weight of each crew.
C.6.4
Each crew shall ensure they maintain a minimum weight of 130 kg at
all times when racing.
C.6.5
Nothing shall prohibit local, national or international authorities
from lowering the specified minimum crew weight for special events where the
nature of the event warrants this action, such as all-women events, junior
events, etc.
C.7
Membership
C.7.1.
At least one crew member shall be a current member of the ICA or a
member of a regional, national or district class association duly
established in accordance with the TASAR class constitution.
