The Southern cross 28 is a 30.42ft cutter designed by Thomas Gillmer and built in fiberglass by C. E. Ryder since 1978.
The Southern cross 28 is a very heavy sailboat which is slightly under powered. It is very stable / stiff and has an excellent righting capability if capsized. It is best suited as a bluewater cruising boat. The fuel capacity is originally very small. There is a short water supply range.
