Interprtation 34 revised March 10th 2006

Interpretation 34 added February 13, 2006

Changes to the Tasar Class Rules effective 2006-01-03

A - Hull weight
A1. Amend the first sentence of rule D.3.1 to read as follows: D.3.1 "A minimum hull weight of 68 kg shall apply for class racing." Leave the rest of D.3.1 unchanged. Delete rule D.3.2.

B - Sails
Rule changes required if mylar sails are adopted

B1. Measuring two jibs
This proposed change was withdrawn.

B2. National letters and sail numbers
Amend the first sentence of rule C.1.3 to read:
" On dacron sails the national letters shall be wholly between the 4th and 5th batten pockets from the head point and the sail numbers shall be wholly between the 3rd and 4th batten pockets from the head point."
Add a new second sentence to read:
" On mylar sails the lower national letters shall be placed on the port side, approximately 50 mm above the 4th batten pocket from the head point, and the upper sail numbers shall be placed on the starboard side, approximately 50 mm below the 4th batten pocket from the head point."

B3. Measurement to head of jib
Amend rule F.1.4 to read as follows:
" For dacron sails, the measurement from the bearing point at the hounds to the aft head point of the jib shall not exceed 115 mm. This rule does not apply to mylar jibs."

B4. Length of whisker pole
This proposed change has been withdrawn. The maximum length for the pole with a mylar jib will be included at a later date.

B5. Jib halyard and furler
Add a new rule F.4.5. "When a mylar jib is used, a jib furler and swivel are not fitted, and a jib halyard and associated fittings, as supplied by the builder, are required. Any replacements of the supplied equipment are subject to all applicable rules, including C.2.4 and F.4.1."

B6. Mylar sails
Add a new a new rule G.2.4: "The mainsail and jib may be of different materials, either mylar or dacron, but may not be changed during an event, except as permitted by rule C.2.1(c)."

B7. Leech take up
Amend rule G.2.3 to read: "For dacron sails, leech take-up not extending more than 150 mm from the leech, for the purpose of compensating for stretch with use, is deemed to be a repair. The associated re-stitching may not extend more than 200 mm from the leech. Leech take up is not permitted for mylar sails."

B8. Hull Weight - this proposal has been added
Amend rule D.3.1 as follows:
• delete "the furler and furler line" from the list of required equipment;
• add "A furler and furler line" to the list of equipment that can be included if it is always used.
If A1 is approved, D.3.1 would then read:
" A minimum hull weight of 68 kg shall apply for class racing. Any ballast required to bring a hull up to the specified minimum weight shall be secured in the cockpit. Hulls shall be weighed dry with shroud pull-backs, hiking straps and all associated adjuster lines and shock cord erectors, inspection port covers and all permanently attached fittings in place. A furler and furler line, and a removable compass with a permanently attached mounting, may be included if they are always fitted when racing. All other equipment shall be removed prior to weighing."

Approved by World Council for circulation and voting 2005/07/04
Revisions approved 2008/08/12

 

2005

Shroud pull backs
C.2.2. (k): "A simple line and block purchase system with a mechanical advantage of two may be attached 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."

Length of mainsheet strop
C.2.3 (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 of the strop, 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.

Hounds to deck measurement
F.1.5.: The measurement from the bearing point at the hounds to the deck immediately in front of the mast step shall not be less than 3720 mm.

Support for top mast
F.3.2.: The top mast shall be supported on an insert located and supported by the upper diamond bolt and having the same cross section as the top mast sleeve.

Notes   
1.         ERS = ISAF Equipment Rules of Sailing
2.         RRS = ISAF Racing Rules of Sailing
3.         "Daggerboard" replaces "centreboard."  Acentreboard is defined in the ERS as "a hull appendage that rotates about a single transverse axis".  A "daggerboard" is defined as "a retractable hull appendage, non-rotating."
4.         "Event" replaces "regatta"
5.         All measurements are given in metric units only.
6.         For list of added rules, see Summary of Changes to Tasar Class Rules (listed by ISAF number).
