5o5 Class Rule Changes

International 505 Class
Rule Changes applicable from 1 April 1997

The new ISAF Racing Rules of Sailing become applicable on 1 April 1997. The 505 class rules did not comply with the new racing rules. The IRC has therefore adopted the following as "minor rule changes", to apply from 1 April 1997.

Clothing Weight
The maximum permitted weight of 10 kilograms being closest to our existing permitted 15 kilograms has been adopted. Note that that the 10 kilogram limit excludes the weight of footwear and a trapeze harness. From 1st April. 1997, weight jackets are no longer permitted. The trapeze harness must be buoyant, and may not weigh more than 2 kilograms. Measurement Rule 12.4 is deleted, and Rule 12.3 now reads.

12.3 (RRS 43.1) A competitor's clothing and equipment shall not weigh more than 10 kilograms, excluding a hiking or trapeze harness and clothing (including footwear) worn only below the knee. In all other respects, the provisions of RRS 43 shall apply.

Propulsion
The propulsion rule has been moved from the Championship Sailing Instructions to the main body of the Measurement rules as a new Rule 13, and the wording (but not the meaning) changed to conform with the new racing rules. Rule 13 reads:
13 Propulsion
13,1 In accordance with RRS 86.1(c), RRS 42.3(b) is not applicable and the following class rule is substituted.

Except on a beat to windward, when surfing (rapidly accelerating down the leeward side of a wave) or planing is possible, the boat's crew may pull the sheet and the guy controlling any sail in order to accelerate a boat down the face of a wave or in response to an increase in the speed of the wind, but not more than three repeated pulls and releases of the sail may be made for each wave or gust of wind.

Sail Numbers on Spinnakers
Minor changes have also been made to the wording of Rule 8.4.4, which now reads.

8.4.4 The ISAF Racing Rules of Sailing ("RRS") Appendix H paragraph 1.3(d) is replaced by the following Class Rule in accordance with Appendix MS of the RRS.

The sail number shall be displayed symmetrically on the front side of a spinnaker. It shall he displayed wholly below an arc whose centre is the head point and whose radius is 40% the mean length of the two leaches and wholly above an arc whose radius is 60% of that dimension.
