First, you will create a path that describes the length of the tiller, and then you will create the shape of the cross-section of the tiller. Execute the following steps:
With the cursor over 3D View, press M, 2, and Enter to move the rudder to Layer 2.
Adjust 3D View so that you can see the entire length of the tiller on the template (the tiller is the handle that controls the rudder).
Press Shift + S and select Cursor to Center. Move the mouse cursor to the vertical center of the right end of the tiller and use the mouse to move the 3D Cursor there.
Press Shift + A, and then select Curve and Bezier from the menu to make a Bézier Curve.
Press R, Y, 90, and Enter.
Press the Tab key to get into Edit Mode. Move the top control point to the center of the left tip of the tiller. Move the other control point to the 3D Cursor's position.
Adjust the control handles so that the curve goes along the center of the tiller outline in the template...
