Which of the following is NOT a requirement for a legal boat under the Marine Safety Act?

The requirement for a legal boat under the Marine Safety Act does not include the necessity of having a fishing license. Fishing licenses are generally related to the legalities of fishing activities rather than the basic operational and safety standards stipulated for boats themselves. A fishing license is required for individuals who wish to fish, but it does not pertain directly to the safety and operational regulations of the vessel.

In contrast, the other options focus on essential safety equipment required for boat operation. Having flotation devices ensures that passengers can stay afloat in an emergency. A fire extinguisher is crucial for addressing fire hazards, and working lights are important for navigation and signaling, especially in low-visibility conditions. These components are part of maintaining safety standards on the water, whereas a fishing license is more about the individual's compliance with fishing regulations rather than the boat's legal status.
