International 10 Sq.m. Sailing Canoe
AMENDMENTS TO ICF CANOE SAILING COMPETITION RULES 2009
ADD TO ARTICLE 6 Unless otherwise specified in the Sailing Instructions, during a competition only two suits of sails, one center-board and one rudder may be used, except in the case of breakage if dispensation from the race committee is granted.
3. ADD New innovations shall conform to these rules and owners are encouraged to seek any necessary interpretations of rules from the National or International Federation before building.
Measurers shall refer to the National Authority innovations that may breach the ‘Spirit of the Rules’ in any way and withhold the signing and issue of a measuring certificate until clarification has been obtained.
5e. REPLACE WITH The outside skin of the hull shall contain no hollows greater than 1mm over an area of 2000mm by 1000mm centered on the BMS. The 2000mm dimension shall be measured fore and aft and parallel to the centerline, 1000mm dimension at right angles to the fore and aft centerline. The two dimensions used to form a rectangle on the hull in plan view. The area of the hull contained within this rectangle shall be checked for any hollows greater than 1mm with a string line pulled tight against the skin of the hull both in the fore and aft plane and moved out board, parallel to the centerline on each side, and in the athwartship plane moved fore and aft perpendicular to the centerline.
9a. INSERT AT BEGINNING Only one center-board shall be carried.
9d. ADD NEW RULE Devices that create dynamic vertical lift on the center-board are prohibited.
RENUMBER EXISTING 9d as 9e (There are no restrictions on the design or materials of the centerboard other than the above rules)
10a INSERT AT BEGINNING Only one rudder shall be carried.
10d. ADD NEW RULE The rudder may have a hydrofoil configured such that it can develop a vertical dynamic lift component while sailing. It shall comprise one lifting element that may be divided by the rudder. It shall be rigidly fixed to the rudder and shall not have any moving parts, flaps or other such devices. A rudder with a hydrofoil shall be used with the hydrofoil immersed below the surface of the water.
RENUMBER 10d as 10e (There are no restrictions on the design or material of the rudder other than the rules above.)
11b. REPLACE WITH The boom excluding fittings shall be capable of passing through a circular hole of 100mm diameter. A boom used for the foresail excluding fittings shall be capable of passing through a circular hole of 30mm diameter. For wishbone booms used for mainsail and/or foresail each side of a wishbone shall be measured separately and shall comply with the same limits.
11e. AMEND TO READ No sail shall have its luff set more than 6360 mm above the underside of the hull
11f. AMEND LAST SENTENCE TO READ No sail shall have its luff set above the underside of this band.
11h. AMEND TO READ The mainsail shall be capable of being lowered and removed from the mast and hull with the canoe floating freely in an upright position without the use of tools. Devices that lock the sail to the mast head shall be operated from deck level.
12b. ADD AT THE END OF SECTION 12b No part of the mainsail shall extend beyond the projection of a line drawn at 110 degrees from the head measured from the luff. A triangular template with edge lengths measuring 300mm, 300mm, and 492mm may be used for the purpose of checking this head angle.
AMEND SECTION ON HULL TO READ Hull weight shall be in accordance with Appendix IV Rule 5f. It shall include spinnaker pole and fittings.
A new set of rules incorporating the amendments will be published by the ICF in due course.
