ABSTRACT:
The invention relates to a novel sailboat rigging, in which two masts placed without shrouds in a common thwartships plane are joined at the masthead and each have a main boom. Both main booms have a carriage that is displaceable in the longitudinal direction and is joined to the foot edge of a mainsail. The mainsail is embodied as a staysail and is guided on a stay that connects the masthead to the back end of the carriage. An articulated attachment of the two carriages by means of connecting rods to a swivel point disposed midway between the two masts offers the opportunity of automatically controlling the shortening and lengthening of the boom by means of the carriage.
