The note says "( Wind relative to boat is irrelevant! )"
Why is it irrelevant?

A reference frame is a set of coordinates that is used to describe the position and motion of an object. It serves as a point of reference for measuring the movement and interactions of other objects in relation to it.
This is because the boat's motion is relative to the water, not the wind. The boat and the water are both moving at the same speed and direction, so the wind's effect is cancelled out.
Yes, wind can have an impact on a boat's motion if the boat is not moving at the same speed and direction as the water. In this case, the wind will push against the boat and affect its speed and direction.
A reference frame provides a consistent and fixed point of reference for measuring the motion of objects. It allows us to accurately describe and predict the movement and interactions of objects in relation to each other.
No, a reference frame is not always necessary, but it is helpful in understanding the motion of objects. In some cases, the motion of an object can be described without a reference frame, such as when the object is moving at a constant speed in a straight line.
