Welcome to the home of the Australian F18 Association. The International Formula 18 class is without a doubt the biggest, most professional and fastest growing class in the world. Even though the Australian fleet has some of the most competitive sailors in the world the Associations focus is on all around participations and complete fleet involvement.

With fleets now extremely active in 6 states (NSW, VIC, TAS, SA,QLD and WA) the association is growing in numbers and participation.

Formula 18 catamaran class rules guiding principals

The box measurement rule allows manufacturers to develop catamarans that are competitively priced yet allowing freedom to builders to develop higher levels of performance. Being open to any manufacturer allows many builders and sail makers to compete and so keep costs to a minimum.

The Class remains aware to keeping development under control, maintaining a good balance between cost and performance.

Corrected crew weights allows fairer racing with more ladies involved as helms and crews.

IF18CA measures hulls, hull appendages, rigs and sails which are required to conform to IF18CA standards, such boat parts only being altered to stay in line with current IF18CA rules.

About sailing F18 Catamaran's

Catamarans are seizing the moment as the AC72s and Olympic selection of the Nacra F17 bring intense media focus.  Indeed not since the beach cat boom of the late 1970s, redolent with “Have a Hobie Day” imagery of bonfires and bikinis on beaches, has the twin-hull revolution looked so promising in Australia.

At the pinnacle of cat racing, the high-performance Formula 18 (F18) class is witnessing unparalleled growth. Five years ago, when current class President Kyle Amadio began his tenure, only 10 boats contested the national championships – in January this year, 38 F18s flocked to Mannering Park on Lake Macquarie NSW for the same event.

International teams came from Italy, Oman and New Zealand, lured by the quality of racing at the front of the fleet. Brett Burvill, builder of the Windrush Edge in Western Australia, drove 40 hours straight with five boats stashed inside a trailer, pausing only for refuelling, a hamburger and to clean a kangaroo off the grille. 

Olympic, America’s Cup and world champions from other classes, both mono and multi, were there for the pure fun of it, mingling with the father-and-son teams, mixed crews and sprinkling of grey nomads, all of varying talents
