Differential tiller arms for marine vessels

1. An advanced steering system for a marine vessel having a plurality of rudders, comprising:

a rudder assembly including an actuator and a plurality of rudders;

a non-linear tiller arm for rudder control;

said non-linear tiller arm having a first member defining a first generally linear axis;

said non-linear tiller arm having a second member defining a second generally linear axis;

said first member and said second member being angularly offset from one-another with respect to said first axis and said second axis;

a tie bar, said tie bar for connection to said non-linear tiller arm;

said non-linear tiller arm having a means for connection to said rudder assembly at one end, and a means for connection to said tie bar at the opposing end; and

upon operation of said actuator, said non-linear tiller arm rotates causing said plurality of rudders to rotate in separate and distinct angular displacements.

2. The apparatus of claim 1 further comprising:

a pair of non-linear tiller arms for rudder control;

each said non-linear tiller arm having a first member defining a first generally linear axis, and a second member defining a second generally linear axis; and

each said first member and said second member being angularly offset from one-another with respect to said first axis and said second axis; and

said tie bar being connected to each said non-linear tiller arm.

3. An advanced steering system for a marine vessel, comprising:

a rudder assembly secured to said marine vessel;

said rudder assembly including an actuator and a pair of rudders;

a pair of differential non-linear tiller arms for rudder control;

each said differential non-linear tiller arm having a first member defining a first generally linear axis, and a second member defining a second generally linear axis;

each said first member and said second member being angularly offset from one-another with respect to said first axis and said second axis;

a tie bar, said tie bar being attached to each said differential non-linear tiller arm;

said actuator controlling movement of at least one said differential non-linear tiller arm, in turn causing movement of the other said differential non-linear tiller arm through said tie bar attachment;

wherein rotation of said differential non-linear tiller arms causes differential and individual rotation of said pair of rudders; and

upon operation of said actuator, said rotation of said differential non-linear tiller arms causes said pair of rudders to rotate in separate and distinct angular displacements.

4. The apparatus of claim 3 further comprising:

an interlocking key, said interlocking key securing said differential non-linear tiller arm to said rudder assembly.
