RL24 yachts shall comply with the AYF definition for Trailable Yacht and must comply with the following in order to qua1ify for a Measurement Certificate.

Strictly one design.

Hull form to R. LEGG registered-design produced from mould approved by the designer.

The completed hull, dry and in sailing condition complying the AYF definition for "Trailable Yacht" shall not weigh less than 454kg.

This weight includes:

-Those fittings bolted, riveted, glued or fibre glassed to the hull for the purpose of attaching standing rigging, or for the purpose of attaching fittings for running rigging.

-Rudder pintles.

-Winch tackle for raising keel

-Any plates or brackets for mounting auxiliary motor.

-Sheet winches

-Instruments permanently mounted.

-All built-in furnishings.

Items that shall be removed for weighing purposes include keel, rudder box and tiller, spars and all standing and running rigging, auxiliary motor and fuel, readily removed furnishings such as bunk cushions, marine toilet, stove, floor boards and similar sundry equipment that the class measurer considers is not permanently fixed.

Any ballast weight to bring a hull up to minimum shall be securely fixed as near as practicable to a position 240mm above the keel line and 4.0maft of the top of the stem.

No craft shall be registered as an RL24 which has substantial modifications to the deck unless such modif1cations have been approved by the RL24 Owner's Association of Australia. This approval shall be sought prior to construction. (Rule adopted at AGM, 1988 Eden NSW)

The shortest distance from underside of cabin top to inside hull skin or moulded floor at yacht’s longitudinal centreline shall be 1.3m minimum.

Shape unrestricted. Minimum weight 100kg.

8.1 Mast Height

8.3m. maximum, measured from cabin top to centre line of halyard sheave

8.2 Mast Section

120mm maximum fore and aft dimension, excluding normal fittings.

8, 3 Foam in mast

Requirement for foam in mast deleted from rules at AGM, 1987 Gladstone QLD,

2.67m. maximum, including fittings, measured from the foreside of the mast.

10. SAILS

10.1 Number of Sails

The number of sails per boat is unrestricted, but only one mast and one suit of sails to be used during racing in State or National title series, The suit to consist of no more than one mainsail, two headsails, and one spinnaker, The notation, (one headsail suitable for use as a storm jib) was deleted at AGM, 1987 Gladstone QLD

10.2 Working Sail Area

The combination of headsail and mainsail in use at any one time shall not exceed 2O sq. m, measured area, sail plan otherwise unrestricted.

10.3 Spinnaker

Shall be symmetrical when folded along its centreline with the leeches together. Maximum measured area 20 sq. m. Shape otherwise unrestricted.

10.4 Sail Area Measurement

The area of all sails shall be measured in accordance with the simplified extract from the AYP Racing Rules 1973–77, appendum E as appended in the class rules.

-. Crew unrestricted.

No trapeze or similar device shall be used. Hiking is permitted, provided that when hiking in the transverse position no part of the body between the middle of the thigh and the feet shall be outboard of the sheerline. When hiking in longitudinal position, at least one full arm and one full leg shall be inboard of the sheerline, (This rule adopted at AGM 1986 Adelaide S.A.)

At all times RL24 yachts shall carry the appropriate safety equipment stipulated by the AYF requirements, or State yachting authority requirements, which is current at that time.

Buoyancy in the form of sealed compartments or closed cell foam with a minimum volume of .55 cu metres must be approximately evenly distributed fore and aft, and athwartships. Closed cell foam should not be used below bilge level.

Recommendation only. This is not part of approved class rules and is a guide only to sailing committees. The maximum average wind speed as recommended by the class association is 30 mph (approx. 48 km/h; 26 kn). It is assumed that the sailing committee will take into account the state of the sea, tide, etc., and the availability of rescue facilities before making a decision to start a race.

The measurement, of sail area for the RL24 is based on the Australian Yachting Federation Racing Rules 1973-77, Addendum E, Section IV. The basic method for mainsail and jib is measure lengths of luff, leech and foot, (these dimensions are used to calculate the "main triangle area") and the offsets, or rounds, of the luff, leech and foot, which along with the first three dimensions are used to calculate the areas of the "rounds", which are added to the main triangle area to make the total. (A hollow leech as on some jibs, may be subtracted). Figure l, shows the measurements, and Fig la, 1b and 1c show the detail of where the measurements are taken. The sails are measured dry, staked out on a flat surface, with battens in place, and with enough tension to remove wrinkles. A spinnaker is measured folded down its centreline, with the luff and foot measurements taken around the luff and foot. The half height, half width is as shown on Fig. 2.
