Notes

One of the earliest and most successful beach catamarans from Australia. Many of the earlier boats were sold to resort hotels, sailing schools, etc.
The original builder was J & S Fiberglass until 1982. The manufacturing rights where then taken over some time later by Mariglass (Seawind Catamarans??) until the mid nineties. Later boats were built by Ross Guinea of Brisbane (Brisbane Catamaran Centre).
A few modifications to the original design have been made over the years to keep the cost down. The rear beam and the traveller track were integrated into one extrusion and a one-piece trampoline replaced the original two piece version. The small cruising jib however, was replaced with a larger racing jib.
Still in production as of 2008.

Most often raced in the following configurations:

Class A Cat or UNA rigged single handed.
Class B Sloop rigged double handed.
Class C Supersloop with trapeze, sloop rigged single handed.
