ABSTRACT:
An improved apparatus for righting an upset catamaran is disclosed. Apparatus are provided to apply and maintain a compressive force in the mast while extending the out-of-water permanent shroud so that a sailor standing on the in-water pontoon and pulling on a righting line fastened to the out-of-water pontoon can easily rotate the out-of-water pontoon over the vertical where gravity will add to the righting moment. The compressive force on the mast permits the shroud extension and resultant mast pivoting without risk of dismasting. Apparatus to limit the mast pivoting to a selected angle are also taught.
