That would be balanced, because the motorboat is not increasing in speed or decreasing in speed.
unbalanced
No. An unbalanced force causes motion, but balanced forces keep a body in motion in a straight line at constant velocity, or at rest at constant 0 velocity.
The forces acting on the car are unbalanced because it is accelerating by changing direction, even though it has constant speed. Unbalanced forces cause acceleration (change in motion). That is what Newton's first law of motion is about.
Anything that is accelerating or decelerating because it is only balanced when something is moving at a constant speed.
The friction force acting upon the turned wheels of the car cause an unbalanced force upon the car and a subsequent acceleration.
unbalanced
Must be unbalanced. Otherwise, the moon would be moving at constant speed in a straight line.
An object with balanced forces acting on it is still. An object with unbalanced forces acting on them moves at an non constant velocity. It is possible for an object to have balanced forces acting on it and yet move in a vacuum.

* Balanced: The vector sum of all forces on an object is zero. The object does not accelerate.* Unbalanced: The vector sum of all forces on an object is NOT zero, the object DOES accelerate.

When the forces on a windmill are unbalanced, the blades may slow down or speed up, or they may change direction. When the blades are rotating at a constant velocity (speed and direction), then the forces are balanced.
The velocity is constant and there is no net or unbalanced force.
Newton's first law, which states that a body at rest remains at rest and a body in motion remains in motion at constant velocity in a straight line unless acted upon by an unbalanced force.
