Abstract
An inboard rudder 6 harbors within a bearing assembly 12 which passes vertically from a hull 10 of a boat 2 to a cockpit floor 8 of the boat 2 such that the inboard rudder 6 can be rotated around a vertical (z) axis 7 by a tiller 14 and raised or lowered by pulling or pushing on the top of rudder 6. Rudder 6 can be rotated about an axis (y) parallel to the width of the boat 2, in the fore and aft direction, by pulling or pushing on tiller 14 thereby altering a sweep angle 28 of the rudder (FIG. 3). Rudder 6 can be rotated about an axis (x) perpendicular to the length of the boat 2.
Claims9
A rudder assembly for inserting into the stern of a boat for steering the boat in water, comprising:
- a postless rudder having a bottom for extending into the water and steering the boat in the water;
- a bearing assembly inserted into the stern of the boat such that it extends from a hull of the boat to a cockpit floor of the boat, said bearing assembly rotatably collaring said rudder such that said rudder is rotatable about a substantially vertical axis within said bearing assembly for steering of the boat.
An inboard rudder assembly for insertion into a boat stern, comprising:
- an inboard rudder;
- a bearing assembly extending from a cockpit floor of said boat to a hull of said boat, said bearing assembly having a first hole which extends the entire length of said bearing assembly, said hole for harboring said rudder, said bearing assembly further including
- a top bearing plate which rides on bearings which sit in a bearing race near the cockpit floor, said top bearing plate having a second hole coaxial with said for hole for harboring said rudder;
- a bottom bearing plate which rides on bearings which sit in a bearing race near the cockpit floor, said bottom bearing plate having a third hole coaxial with said first and second holes for harboring said rudder;
- wherein said top and bottom bearing plates are rigidly connected to one another such that said top bearing plate and bottom bearing plate rotate in unison.
