Farrier F-9A

 Home-built from plans

Brand:

Farrier

Designed by:

Farrier Marine

Yard(s):

TPI Composites Inc.

Description:

The F-9A is a high performing multihull for home-building with sufficient amenities and accommodation for longer range cruising. This design is a forerunner of the factory-produced OSTAC 31 and Corsair 31, with which many parts are interchangeable. Plans for aft cockpit and aft cabin versions are available.

Aft cabin models have 4-5 berths and standing headroom in the galley and table seating for 4. A separate heads area forward can be curtained off. The forepeak can be a cosy double or single bunk.

Early sea trials showed the F-9 to have a 12% speed advantage over the highly acclaimed cruiser/racer, the F-27 that was first launched in 1985. In 1991, the same year as it was introduced, the F-31 was judged Australian Sailboat of the Year and in 1992 an F-31 won the bi-annial Australian Offshore Multihull Championships.

The F-9AX is a roomier model with a wider centre hull. The F-9R is a higher performing model, lighter and with more sail area.
