Based on a request - here is an electronic version of the 2 Meter Multihull Class Rules. I received these in late 1999 and cannot verify if there have been any changes since then. One would need to check with the French to verify these are current.

HULL(s) / FLOATS
3.1 Definition
(3.1.1) The boat shall be a multihull made of more than one hull or float linked by one or more cross beams.A hull or float is made of the floating structure, the deck, the rudder(s), the appendage(s), the bow bumper, but does not include the rig(s)
A catamaran is made of two hulls. A trimaran is made of a central hull and two floats. A proa (Spelling corrected) is made of a hull and a float. Any other kind of multihull is permitted as long as there are a minimum of one hull and one float.
3.2 Identification Marks
(3.2.1) Each hull/float shall carry in an easily visible location, either painted, engraved or moulded in, the boat’s national letters and registration number.
(3.2.2) On the external surface of the hulls or decks the multihull’s national letter and registration number shall be displayed clearly and legibly, with a minimum height of 20 mm.
(3.2.3) When a multihull has several sets of floats, each set shall be registered on a separate measurement certificate. This set registration number shall be the registration number suffixed by a letter. (ex: 123/A)
3.3 Construction
(3.3.1) a) The multihull shall not be longer than 2000 mm and shall not be wider than 2000 mm
The length is measured along the centerline of the multihull, between lines drawn at 90 degrees of the centerline, tangent to the most forward stem(s) and to the most backward stern(s). For the measurement, the multihull waterline should be held as parallel as possible to the surface plan used as a reference basis. The two lines define the overall length measurement lines.
The width is measured at the widest point of the multihull at a 90 degree angle from the centerline.
b) Each bow bumper shall be made of elastomeric material and shall project a minimum of 20 mm.

APPENDAGES AND BALLAST
4.1 Ballast
(4.1.1) Moveable ballast shall not extend beyond the multihull.
(4.1.2) Ballast shall not be made of a material of higher density than lead (11,3 Kg/dm3)
(4.1.3) Liquid ballast are permitted and shall be fresh water, or water taken from the sailing area.
(4.1.4) Solid and/or liquid ballast may be added, removed or moved at any time during a race or series of races. -
RIG
5.1 Masts
(5.1.1) The overall mast height (windvane excluded) shall not exceed 2800mm above the average deck level. When there is no deck (catamaran), the measurement must be done from a line drawn from the average decks level of the multihull
5.2 Other Rigging Rules
(5.2.1) No part of the rig shall extend beyond the overall length measurement lines when the sails are held along the centerline of the multihull.
- SAILS
6.1 Identification Marks
(6.1.1) Sails shall carry identification marks in accordance with the International Yacht Racing Rules.
(6.1.2) The class insignia shall be the logo defined on the front of this document.
