1.1 The X-99 is a one-design class.
The intention of these rules is to ensure that all boats are as alike as
possible in hull shapes, appendages, weight, weight distribution, rig and sail
plan. The construction of the hull, spars, sails and rigging are controlled by
these rules except where variations are specifically permitted.
1.2 The word "shall" is
mandatory and the word "may" or "can" are permissive,
1.3 Wherever in these rules the
words "Class Rules" or "Standard Build" are used they shall
be taken as included in the official drawings and diagrams as produced by
X-Yachts and shall mean as fitted by the builder.
1.4 In general it should be
considered that any alteration to the Standard Build is not permitted unless
specifically permitted by these rules.
2.1 Except where other methods of
measurement are specifically indicated all measurements shall be carried out in
accordance with the ISAF measurement instructions.
2.2 In the case of a measurement
dispute on hull, spars, sails, fittings, equipment to be carried, keel, rudder

Committee for a written ruling.
If a yacht owner or skipper, being a
paid-up member of their respective National Association, wishes to question one
of the Rules, he/she should put their question to their National representative
on the International Board, who will, if considered appropriate, forward it to
all members of the International Board who shall make a judgement within one
month. For a Ruling to be made it must be agreed by a majority of Board members
(>50%),
Any question must be placed with the
National representative with a minimum of three months' notice before an
