 A.10.2 Save as provided in A.10.3 sail numbers shall correspond to the hull number.  However, competitors may request permission in writing to the Technical Committe (or at a regatta,for that regatta only, the Chief Measurer)to use a different sail number to the hull number. Permission will only be granted in exceptionalcases and the Committee/Chief Measurer’s decision shall be final.

C.6.1.3  (c) The tips of the surface ridges of the non-slip on the deck and/or cockpit floor may be very lightly sanded to reduce its sharpness and make it less abrasive; however, only the topsof the peaks may be abraded, the texture must be maintained.

(ii) ”velcro” type fastening,hooks, hooked blocks, and snap shackles to facilitate connection of the outhaulprimary line to the block, vang block to the mast, and outhaul and Cunningham shockcord,; -provided that this does not modify the intended purpose, purchase or action of any equipment and provided that such material shall not be used to create a fitting or extend a function of a permitted fitting or alter the shape of the boat.

 C.6.1.3 alt=j (k)One single righting line of maximum length of 1.5 meters may be attached to each side of the hull attached tothe location of the rear most plastic barrel under the gunwale shownin the RS Aero Rigging Manual, along with shock cord from the free end running around through the RS Sailing supplied bowfairlead under the gunwale. 

 C.6.1.3 alt=m  (n)Shockcord of maximum diameter 6mm:(i)for centralising the tiller,(ii)around the toe strap webbingto hold it up(iii)to retract or reduce slack in ropes when released/uncleated(including to pull the outhaul and Cunninghamcontrols off);this may include: (α)shockcord tied to one or both mainsheet block hangers extending through the clew of the mainsail(and may include a hook for attachment), and (β)attached to the Cunninghamprimary line and passed over the mast button,or temporarily connectedto or passed throughthe main halyard(a hookmay be used to allow fast release), however, any interaction withthe main halyard must be removable within 5secondsandmust not require anyknot/sto be undone (the main halyard must be able tobe lowered without complication resulting from shock corduse). 

C.6.1.3 alt=s (t)The daggerboardshallbe secured to the boatwith shockcord, and/or rope, which may include a snap hookand ring; a small rope loop may be tied to a traveller retainer and thedaggerboardshockcord may pass through it to deflect that shockcord. 
  C.6.1.3 alt=u (v) The Cunningham secondary line  double blocktied to the hull (not the floating one)may be replaced by 2 x single blocks of equivalent size but must be attached to the hull in the same way and in the same location.(w) Padding of maximumthickness of 3mm may be stuck (using adhesive) to the (i) cockpit floor and/or (ii) deck adjacent the centreboard case, but if it is, it must cover the entirety of the non-slip in that area and follow the outline of that non-slip.Any padding must be single colour black, white or grey.
