Laser 28 International Class Association Rules
Amended January 2015
The International authority for the class racing rules shall be the Laser 28 Executive Council through its Chief Measurer. The English text of the Laser 28 rules shall govern.
a) Fundamental Class Rule
For the purpose of Laser 28 Class racing, except as specifically permitted in these rules, it is prohibited to remove or make any additions or alterations or make any changes in shape or profile to the hull, keel, rudder, saildrive, deck, spars, construction, equipment, type of equipment, fittings, type of fittings, placing of fittings, standing rigging, and running rigging as originally supplied with the boat.
Any attempts to make changes not specifically permitted is a breach of both the spirit and the substance of these rules.
b) Basic Principles and Intent of these Rules
To ensure fair class racing. It is the intent of these rules and specifications that the yachts have equal potential speed when they are well prepared and well maintained. These rules intend that no racing advantage be attainable from the absence or addition of features or equipment. Nor from modifications to the hull, keel, rudder, saildrive, deck, spars, construction, equipment, type of equipment, fittings, type of fittings, placing of fittings, standing rigging, and running rigging which makes the yacht deviate from the standard LASER 28 Sailboat. Furthermore, it is the intent of these rules to equalise the potential speed of the participating yachts so that the skill of the skipper and crew in tuning, maintaining, and racing the yacht are the major factors in the outcome of class racing.
A Laser 28 shall be built only by builders licensed by the Copyright Holder and shall be constructed and finished according to the original design and building specification of the Copyright Holder.
a) The hull, keel, rudder, saildrive, deck, spars, standing rigging, running rigging, fittings and the placing of fittings and equipment shall conform to the original design. Tolerances are intended to allow for manufacturing discrepancies only and shall not be used to gain an advantage or alter the original design. In dispute, measurement of yachts can only be validated by a recognised measurer of the Laser 28 International Class Association. In the case of a measurement dispute on the hull, keel, rudder, saildrive, deck, spars, rigging, type of fittings and equipment and the placing of same not explicitly covered by these Rules, the following procedure shall be adopted:
b) A sample of 5 other boats shall be taken and measured using identical techniques. The dimensions of the disputed boat shall be equal to or between the maximum and minimum dimensions obtained from these 5 boats. If the boat in question is outside these dimensions the yacht shall be disqualified and the matter, together with any relevant information, shall be reported to The Council of the Laser 28 International Class Association at its Head Office.
c) Measurer Discretion
A Laser 28 Class Measurer shall report to the L28ICA Executive Council anything which might be considered to be a departure from the strict one design criteria or the intended nature of the class. Measurement of said yacht(s) may be revoked by the L28ICA Executive Council even if the specific requirements of the rules are satisfied.
5. Owners' Responsibilities
It is the responsibility of the owner to ensure that the yacht complies with current class rules before racing in all Laser 28 one design events.
