The International A-Division Catamaran Association (I.A.C.A.) was created later than 30 years ago.

The objectives of the I.A.C.A. are to promote and further the interests of the A-Division Catamarans throughout the world including:  To maintain the restricted design character of the A-Division Catamaran. To co-ordinate and manage the affairs of the Division. To make recommendations on the control of the Division to the ISAF International Sailing Federation. To encourage and co-ordinate National and International competitions within the A-Division Catamarans.

Now I.A.C.A. is managed by its President, Stefano Sirri (ITA) and Secretary, Pieter Saarberg (NED)
