Every animation has at least two keyframes, one for the starting point and one for the ending point (press F6 to insert Keyframe).

To add a motion tween, right-click between the two keyframes and select “Create Classic Motion Tween”.

Import bitmaps by dragging them in and out of the CC Library, or File Import.

Add points to a vector shape by holding down the option key( alt on PC) and dragging with your mouse.

Right-click on layer with a classic motion tween and select “Add Classic Motion Guide” to animate along a path. Draw a path (lock center point of object to path on all keyframes).

Select the first keyframe and click “Orient to Path” in the Properties panel to animate the object along the guide.

Rotate the boat (press Q to Transform) along path on both keyframes so the animation orients to the path.
