INTRODUCTION
This introduction only provides an informal background, and the Liberty Class Rules proper
begin on the next page.
Previously known as the Access Liberty, the Liberty hulls, hull appendages, rigs and sails are
manufacturer controlled.
Liberty hulls, hull appendages, rigs and sails shall be manufactured only by Hansa Sailing
Licensed Manufacturers – in the class rules referred to as licensed builders (Hansa Licensed
Builders - HLB). Equipment is required to comply with the Hansa Liberty Building
Specification and is subject to World Sailing (WS) approved manufacturing control system.
Liberty hulls, hull appendages, rigs and sails may, after having left the manufacturer, only bealtered to the extent permitted in Section C of the class rules.
Owners and crews should be aware that compliance with rules in Section C is NOT checkedas part of the certification process.
Rules regulating the use of equipment during a race are contained in Section C of these classrules, in ERS Part I, in the Racing Rules of Sailing, and in the NoR/SIs.
Event Equipment Inspection and Measurement Procedures are outlined in the Hansa Classes
Measurement Procedures document available from the technical section of the Class Website
www.hansaclass.org.
The Hansa Classes Race Management Guide, including requirements for authorisedChampionships, a Notice of Race and Sailing Instructions Guide, notes regarding
Interpretation of Class Rules and advice for Race Committees, is available from the technicalsection of the Class Website www.hansaclass.org.
The design principle of the class is that the racing results should depend solely on theattributes and skills of the crew rather than differences between boats and the way that they
are rigged. The objective of these class rules is to implement this concept in practice.
PLEASE REMEMBER:
THESE RULES ARE CLOSED CLASS RULES WHERE IF IT DOES NOTSPECIFICALLY SAY THAT YOU MAY – THEN YOU SHALL NOT.
COMPONENTS, AND THEIR USE, ARE DEFINED BY THEIR DESCRIPTION.

The rules in Part III are closed class rules. Measurement shall be carried out inaccordance with the ERS except where varied in this Part.

Section H
H.1 Procedure for Calculation of Regatta Mean Weight (RMW) and
Sailor Correction Weight (SCW).
WEIGHT EQUALISATION(a) At events where a sailor weight equalisation regime is specified in the Notice of Race,the following rules and procedures shall apply.
(b) The purpose of Sailor Weight Equalisation is to ensure that the on-the-water weight ofa sailor and their boat is not less than a Regatta Minimum Weight (RMW). This is tobe achieved by placing ballast, normally in the form of packets of lead shot or othersimilar material, in the cavities of the boat’s seat.
(c) The following procedure may be used: (1) Record the weight of the sailor in dry clothing wearing sailing clothing
appropriate to the conditions and personal flotation device.
(2) Record the weight of any necessary equipment for an individual sailor, such as
ventilators, respirators and batteries for any servo assist control system.
(3) Record the weight of the hull in the condition described in C.6.4 as appropriate
including any required Corrector Weights.
(4) Record the weight of the keel.
(5) Total all the weights recorded for each sailor/boat combination. This should
represent the potential ‘on the water’ weight of a sailor/boat, excluding sails andspars.
(d) The Race Technical Committee (RTC) will set a RMW for the event based on thedata collected:(1) Where the maximum sailor/boat weight is less than the median sailor/boat weightplus 20kgs then the maximum sailor/boat weight shall be declared as the RMW.
(2) Where the maximum sailor/boat weight is greater than the median sailor/boatweight plus 20kgs then the median sailor/boat weight plus 20kgs shall bedeclared as the RMW.
(e) Calculate the ballast to the nearest kg required to be placed in each boat – the Sailor
Corrector Weight (SCW). Note, some sailor/boat combinations may be considerably
heavier than the RMW even without any ballast.
(f) The Weight Equalisation Table for the event, showing the combined weights
recorded for each sailor/boat combination, the RMW and the SCW shall be
published on the Official Event Notice Board.
(g) Install the appropriate SCW in boats. Spot checks may be made on boats to ensurethat boats have the correct ballast during racing.
(h) Where there are not sufficient Corrector Weights available, the RMW may be
adjusted by the RTC to achieve an equitable distribution of SCW.
