Patent ID: 8622012

Claim:
An arrangement configured for guiding and preventing jamming of an interceptor member for a dynamic control of running trim and list of a boat, said boat comprising at least one hull having a stern, said arrangement comprising: an elongated housing member mounted on the stern of the boat, said housing member having front and rear walls and extending transversely along the stern, said housing member configured for fully enclosing an interceptor member in a first end position and partially enclosing said interceptor member in a second end position; and a guiding means fixedly and rotatably arranged in a cavity formed in one of the front and rear walls of the housing member, the guiding means configured to guide the interceptor member between the first end position and the second end position, the guiding means comprising: an elongated rotatable rod disposed substantially horizontally within the cavity and arranged to displace the interceptor member in a substantially vertical direction between the first and second end positions, the rotatable rod comprising: a first end and an opposing second end; a first spur gear on the first end that is configured to mesh with a first gear rack on a first side of the interceptor member, and a second spur gear on the second end that is configured to mesh with a second gear rack on a second side of the interceptor member, said housing member mounted on the stern so that when the interceptor member is in the second end position, water pressure acting on a bottom of the hull in front of the interceptor member is higher relative to a water pressure when the interceptor member is in the first end position.
