Rudders for boats, particularly for pleasure boats

摘要

A boat rudder comprises a rudder-blade hinged in its upper part to a substantially horizontal pin carried by a rudder-blade support, which support is hinged to a substantially vertical pin. The boat rudder further comprises a bar fixed to a bar support the rear part of which is hinged to the upper part of the rudder blade. A locking device, comprising a stop member carried by the bar support and a jamming member carried by the rudder-blade support, is provided for jamming the bar support in relation to the rudder-blade support. It is fitted with a balancing adjustment device for adjusting the normal working position of the rudder-blade and a longitudinal displacement arrangement for varying the distance between the stop member and the pin hinging the bar support to the rudder-blade.
