Notes

One of Arthur Robb's most popular designs and a very successful racer. (A sister ship was winner of the Sidney-Hobart Race in 1959 & 1960).
Cheoy Lee shipyard built at least 20 boats of teak, many which went to the US. By the mid 1960's the same yard had developed a fiberglass version also for export to the US and elsewhere. Rig type and dimensions vary widely. The original drawings show a fractional rig.
