Class Rules



The Marblehead was developed by Roy L Clough of the Marblehead Model Yacht Club in Massachusetts, USA and given International status by the predecessor of the ISAF-RSD in 1937.

A restricted development class, the Marblehead is controlled by a few maximum dimensions, overall length (1.29 metres), sail area (0.5161 square metres) and draft of 660 mm. There is ample scope to develop hull shape, rigs, foils etc. Current designs are around the 4 Kg all up weight

The most popular of the International classes for many years until recently challenged for this status by the IOM, the Marblehead is currently sailed in all Australian States except WA & ACT.
Good fleet numbers can be found in NSW, SA, Tas, Vic & Qld.
