Patent ID: 8857358

Claim:
Rudder group ( 10 ) for boats ( 100 ) comprising a rudder blade ( 12 ) that is releasably coupled to a rudder pin ( 11 ) to form a releasable coupling with said rudder pin ( 11 ), said rudder pin ( 11 ) being able to rotate along an axis (A) passing on the plan of said rudder blade ( 12 ) to define the forward direction of said boat ( 100 ), said rudder blade ( 12 ) also being connected in a rotatable manner to a support element ( 14 ) fitted onto said rudder pin ( 11 ) so that said rudder blade ( 12 ), when it is released from said rudder pin ( 11 ), can freely rotate between a lowered position, wherein it is arranged longitudinally with respect to said rudder pin ( 11 ), and a maximum raised position wherein it is substantially perpendicular to said rudder pin ( 11 ), characterized in that said releasable coupling of said rudder blade ( 12 ) with said rudder pin ( 11 ) is obtained through a connection element ( 13 ) that can break at a predetermined load to free the rotation of said rudder blade ( 12 ) with respect to said support element ( 14 ) wherein the end portion of said rudder pin ( 11 ) coupled with said rudder blade ( 12 ) is fork shaped to receive said rudder blade ( 12 ), said fork having a width such as to allow the insertion of said rudder blade ( 12 ) with a tolerance that is sufficient to allow it to rotate when it is released by said rudder pin ( 11 ).
