The GC32 International Class Association (ICA) was set up to administer, oversee and promote regattas and the other sailing activities of the GC32 one design foiling catamaran internationally.

The GC32 ICA was founded by Laurent Lenne, Flavio Marazzi, Andrew MacPherson and Christian Peer in 2014 with Flavio Marazzi elected President. Christian Scherrer became Class Manager in October 2015, while Simon Delzoppo took over as President in 2017.

The GC32 ICA maintains the one design integrity of the GC32 via its Class Rules and Regulations. While the GC32 is a strict one design, the ICA permits strictly controlled modernisation of the boat. This ensures racing remains competitive and fair, while enabling the GC32 to remain cutting edge, helping to preserve boat resale values.

Changes to the GC32 Class Rules and Regulations are made by voting of the ICA membership at its AGM.

The GC32 ICA monitors and polices the GC32 one design rule via its appointed Class Measurer. It promotes a professional organisational structure for the management, development, execution and promotion of GC32 sailing events worldwide.

The GC32 ICA also offers a forum to GC32 owners for the exchange of information and experience about GC32 foiling catamaran racing.

The GC32 ICA represents its membership when negotiating with third parties, such as federations and authorities like World Sailing.

The GC32 ICA received recognition by World Sailing in 2017, allowing it hold an annual World Championship.
