Answer: B. Methyl isocynide

    • C. Silicone is absorbed too quickly by leather to be useful

  • In maintaining a proper look out the master should take into account all relevant factors except

    • A. Visibility
    • B. Steering control
    • C. Dense traffic
    • D. Sound signaling apparatus
  • Answer: B. Steering control

    When maintaining a proper lookout, the master should consider various factors to ensure the safety of the vessel. Visibility is crucial as it allows the master to see any potential hazards or obstacles in the surroundings. Dense traffic is another important factor to consider as it affects the vessel's maneuverability and requires extra caution. Sound signaling apparatus is also relevant as it helps in communication and alerting other vessels. However, steering control is not directly related to maintaining a lookout but rather to maneuvering the vessel. Therefore, it is not a relevant factor to consider in this context.
