Building Specification

Maintenance shall constitute work required to retain the original condition of an item of equipment whilst compensating for normal wear and tear in order to achieve its maximum useful life. This includes preventative maintenance which shall be taken as the systematic inspection, detection and prevention of incipient failures before they become actual or major failures.

Application of an additional layer or layers of a Permitted Material to the surface. The purpose of painting is to replace existing surface protection on a like for like basis. Painting may require prior preparation of the surface which may involve light abrassion but not fairing unless otherwise permitted.

Application of small quantities of permitted polishing compounds (as published on the ICA website from time to time) on the hull, foils and rig of the boat in order to reduce the surface roughness.

Removal, solely for a purpose specifially permited in these Rules, including for Repair of a component, of part of the outermost surface through use of an abrasive material with or without a lubricating agent, which after final repair does not alter the shape of a component or texture of of the surface of the Originally supplied item.

See painting, polishing and sanding soley in order to complete a Repair.

The application of small quantities of detergents or similar agents the purpose of which is to remove residue on the surface which was not part of the original or subsequently modified surface.

The removal or reshaping of irregularities within the surface form.

Corrective action following unintended and genuine damage to a component, or a manufacturing defect. Repairs shall be carried out using only Permitted Material in the same weight and amount as Originally Supplied. Repair of a manufacrturing defect shall only be made after prior approval from LM. Repairs shall constitute work required to restore the original condition of an item of equipment whilst compensating for any additional material required to return the component to its original characteristics, including by filling, sanding and polishing. Any repair shall (i) only be to the damaged area, and (ii) not be used to reinforce or strengthen a part.

The same material as used in the manufacture of the relevant part of the boat and as specified in the Construction Manual. A list shall be published on the ICA website from time to time; if you are uncertain then you must consult with the LIC before proceding.

51 - 60 - Aero 5

71 - 80 - Aero 7

91 - 100 - Aero 9

(i) only be manufactured by a LM who shall only produce them from moulds taken from the Master Plugs/molds held by LIC and in accordance with the Building Specification; the moulds and products from the moulds shall not be altered other than as prior approved in writing by LIC;

(ii) only be supplied by RS, or an RS authorised distributor for the boat;
and

(iii) shall carry a LIC equipment label certifying it as Originally Supplied.

(a) the LIC or Chief Measurer of the ICA (if the LIC cannot be contacted) shall be consulted and provided with full details of the specification or item in question of the offending boat.

(b) the LIC will or the Chief Measurer will after taking direction from the LIC give a final ruling in line with the LICs direction regarding the correct specification or interpretation of the Building Specification as the case may require. That ruling will be referred to the Race Committee for actioning.

(c) If the LIC or Chief Measurer is not contactable prior to the end of a Regatta the matter will be reported to Race committee, who may make a ruling and will also promptly report full details of all items of equipment lying outside the accepted deviation, corresponding Building Specification/s or Class Rules to the LIC.

(d) If any specification/s of the disputed boat or item of equipment does not comply with the Class Rules or deviates from the Building Specification/s or is not supplied by RS, an RS licensed distributor for the class or an LM (where required by the Class Rules) then the LIC will make a final decision regarding use of the equipment at future events.

(a) RRS G1.3(a) is changed so that only one Class insignia on one side of the sail is required.

(b) RRS G1.3(a) is changed so that national letters and sail numbers are not required to be wholly above an arc whose centre is the head point and whose radius is 60% of the leech length.

(c) RRS 42.3 is changed by adding: “Where stipulated in the SI, if the average wind speed is clearly over 10 knots across the course the race committee may signal in accordance with RRS Appendix P5 that pumping, rocking and ooching are permitted, except (i) prior to the start, and (ii) when the boat is on a leg of the course designated in the SI as a windward leg.” this changes RRS 42.2(a), RRS 42.2(b), RRS 42.2(c).

(d) RRS Appendix G1.3(c) & (d) shall not apply.

(a) The RS Aero may be raced with either the RS Aero 5, RS Aero 7 or RS Aero 9 rig. A boat shall nominate the rig size used at the start of a regatta series and this shall apply to all races. In the event that no rig size is stipulated at registration, the sail used in the first race shall be deemed to be the rig entered on the form.

(b) The RS Aero class rules cover three classes of boat determined by rig size:

• RS Aero 5

• RS Aero 7

• RS Aero 9

If there are not sufficient numbers of boats of an individual class of one rig size at an event, then the notice of race or sailing instruction may proscribe that boats race together. Recommended standard wording for this can be seen in Section H.

(c) It is not permitted to change a rig on the water.

(d) The vang cleat fitting shall always be removable without the use of tools.

Where boats and/or equipment is supplied to the entire fleet for a regatta series:

The mount for a mechanical wind indication device at the top of the mast will use the Originally supplied fitting or be screwed in place using the original screw holes.

In addition to the optional equipment referred to in C.5.1, where stipulated in the SI and where supplied by the Organising Authority, one or more devices may be used which have the capability to measure, display, record and broadcast information relating to the boat’s position, heading, header and lift information, VMG, time, and/or speed. Such devices will not provide any information or data to the crew during a race.

The following is permitted without approval; unless stated otherwise. Items mentioned in this section may be obtained from any manufacturer or supplier providing that any replacement is a like for like type, weight and size as the Originally Supplied item, and performs the same function and does not modify the effective purchase, or rigging or sheeting position:

(a) Polishing of the hull, hull appendages, mast and boom is permitted provided that the intention or effect is not to lighten the equipment or improve or alter the material shape from that Originally Supplied.

(b) Lubricant on fittings, mast join, mast collar, gooseneck, gooseneck pulleys, boom end (to enable the clew strap to slide more easily); boom end pulley, mast track, and sail (only in the direct vicinity of the tell-tales) only; it shall not be used on the hull, hull appendages or elsewhere.

(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 tops of the peaks may be abraded, the texture must be maintained. If the texture becomes relatively smooth (however this occurs), it must be reinstated to its Originally supplied state. NOTE: the grip may not be substantially reduced, and the areas may not be sanded smooth (except as provided in C.6.1.3 (w) below for padding).

(d) The use of (i) flexible adhesive tape to secure knots in rope and shock cord, or stop the end of the rope fraying, or to secure the toe strap, or to protect the surface of the hull from wear by blocks, and (ii) ”velcro” type fastening, hooks, hooked blocks, and snap shackles to facilitate connection of the outhaul primary 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.

(e) Calibration marks of any kind.

(f) Additional drainage holes in the stern and inspection hatches in the deck provided they do not compromise the watertight integrity or reduce the weight of the hull.

(g) Packing wedges no thicker than 5mm may be fitted under cleats.

(h) 1 x Cam cleat may be screwed to each side-deck for the mainsheet but only in the designated area marked on the deck and as illustrated in the Rigging Manual; an RS Sailing supplied detachable single central swivel cam base and cam cleat may be attached to the eyelet at the end of the toe strap as shown in the Rigging Manual (no other fitting may be used and it must be detachable without removing screws or the like).

(i) One of the rudder pintels may be drilled and pinned to further secure the rudder stock to the boat.

(j) The cleat on the tiller to secure the rudder downhaul may be substituted for an auto-release type of similar size.

(k) One single righting line of maximum length of 1.5 meters may be attached to each side of the hull attached to the location of the rear most plastic barrel under the gunwale shown in the RS Aero Rigging Manual, along with shock cord from the free end running around through the RS Sailing supplied bow fairlead under the gunwale.

(l) The Originally Supplied tiller may be shortened but the length shall be no less than 700mm.

(m) A single tiller extension of any material and length may be used.

(n) Shockcord of maximum diameter 6mm:

(i) for centralising the tiller,

(ii) around the toe strap webbing to hold it up

(iii) to retract or reduce slack in ropes when released/uncleated (including to pull the outhaul and Cunningham controls off); this may include: (α) shock cord 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 Cunningham primary line and passed over the mast button, or temporarily connected to or passed through the main halyard (a hook may be used to allow fast release), however, any interaction with the main halyard must be removable within 5 seconds and must not require any knot/s to be undone (the main halyard must be able to be lowered without complication resulting from shock cord use).

(o) Any of the mainsheet blocks may be replaced by a ratchet block of similar size to the block as Originally Supplied.

(p) It is permitted to “re-lead” the tails/secondary lines of the Cunningham and outhaul lines only and to use additional shockcord, rope, rings (or closed thimbles in place of rings) and blocks for the sole purpose of routing to tidy the Cunningham and outhaul line tails provided that no further holes are drilled in the hull or rig. All additional blocks or rings shall be attached by separate rope or shock cord. The use of adhesive is not permitted. The redundant fittings (namely the tubes and fairlead and their screws under the gunwale and bow) may be removed but the holes must be filled and made watertight. The through deck angled exit bushes will not be removed.

(q) It is permitted to attach to the gooseneck a block of no more than 20mm diameter using rope tied around the vang gooseneck block (the attached block being no more 60mm from the gooseneck block) and to lead the vang rope through that attached block rather than the gooseneck block.

(r) A “JC” strap with a maximum shockcord thickness of 8mm may be fitted as shown in the Rigging Manual to pull the boom forward whilst sailing downwind.

(s) Silicon sealant, elastic polyurethane, or adhesive may be used to retain and seal screws and/or bolts in place and placed on the ends to cover exposed sharp edges.

(t) The daggerboard shall be secured to the boat with shockcord, and/or rope, which may include a snap hook and ring; a small rope loop may be tied to a traveller retainer and the daggerboard shockcord may pass through it to deflect that shockcord.

(u) The screws attaching the bottom rudder gudgeon may be replaced by bolts, and up to 2 washers may be used each side between the bolt head and the gudgeon.

(v) The Cunningham secondary line double block tied 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 maximum thickness 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. It may not contain any logo other than RS. It is permitted to sand the non-slip surface to obtain a good adhesion surface for the padding, however, if the padding is removed, the non-slip must be reinstated to its Originally supplied state. NOTE: (i) padding may not be placed elsewhere, and (ii) padding must be adhered to the hull over the entirety of one face/surface (temporary adhesive breakdown within 10mm of edge excluded).

(x) Originally Supplied 18mm blocks may be changed for similar blocks up to 20mm diameter.

(a) Maintenance of the rig, fittings, fastenings, ropes and shockcord is permitted and includes: (i) the replacement of fastenings and fittings with alternatives provided that the equipment is replaced in the Originally Supplied position using the same fitting and fastening as that Originally Supplied unless otherwise permitted by these Class Rules; and (ii) upgrading of one or more parts from those Originally Supplied when the boat was purchased to those as supplied on new boats by an LM which were not supplied with the original boat.

(b) the following parts or equipment may be replaced using parts obtained from any supplier provided that the replacement is placed in the same position and attached in the same way and is a like for like type, weight and similar size as the Originally Supplied item and does not alter the velocity ratio or purchase, and performs the same function (rope sizes are shown in Annex 1 below but may be of any material):

(iii) only uses Permitted material,

(iv) complies with these Class Rules, and

(v) is done in such a way that the shape, weight distribution, characteristics, performance and function of the item as Originally Supplied are not affected.

Any repair shall not be used to reinforce an existing part, change the shape or add a function. Any repair which is substantial, or exceeds more than 5% of the total area of the item, or may alter the weight, profile, structure, air and/or water tight integrity of the item shall be referred to and be prior approved by LIC (which may impose such conditions as it considers appropriate, including stipulating the repairer) before being carried out in order to be in compliance with these Class Rules; the LIC may require the Repair to be carried out by LIC or a repairer appointed by LIC. Repairs to the sail must use a similar type and weight of material to the Originally Supplied. Repair to the sail exceeding 5% of the area or which are to the luff or bolt rope shall only be made by LIC or its designated repairer. Replacement of the entire window on a like for like basis is permitted if it is damaged beyond repair. If you are in doubt whether the damage may be repaired by you without approval of LIC you will refer full details to and consult LIC for determination by LIC.

Under this rule the nominated or all RS Aeros may race together as one fleet and may use time correction as defined in H.2.1. However, if there are sufficient entries in an RS Aero class, that class/es shall preferably race independently without time correction.

H.1.2.1 Under this rule, if there are more than 10 entries (or such other number as the NOR & SI shall specify) at the start of an event or series in the RS Aero 5 Class under the age of 17 on the 31st December of the year in which the event or series start they may race as an individual fleet.

H.1.2.2 Under this rule, if there are more than 10 entries (or such other number as the NOR & SI shall specify) at the start of an event or series in the RS Aero 7 Class under the age of 19 on the 31st December of the year in which the event or series start they may race as an individual fleet.

H.1.2.3 Under this rule, if there are more than 10 entries (or such other number as the NOR & SI shall specify) at the start of an event or series in the RS Aero 9 Class under the age of 21 on the 31st December of the year in which the event or series start they may race as an individual fleet.

H.1.3 Under this rule, if there are more than 10 entries (or such other number as the NOR & SI shall specify) at the start of an event or series in the RS Aero 5, RS Aero 7, and/or RS Aero 9 Class who are female they may race as an individual fleet.

It is recommended that the following division factor (which may be amended from time to time as shown on the ICA website at www.rsaerosailing.org.) be applied to the elapsed time to calculate the corrected times for scoring of multiple rig fleets:

Aero 9 - 0.960

Aero 7 - 1.000

Aero 5 - 1.050

The nominated rig (9, 7 or 5) will be used for any time correction factor. Alternatively, some fleets may prefer to use the yardstick in place in their country from time to time.
