  1. What is the required sound signal for a power-driven vessel underway in restricted visibility, as specified in the COLREGS (Rule 35)?

    Answer: One prolonged blast at intervals of not more than 2 minutes

    COLREGS Rule 35 requires a power-driven vessel making way in restricted visibility to sound one prolonged blast at intervals of not more than 2 minutes.

  2. Which USCG regulation requires that all Type I, II, and III life jackets aboard recreational vessels be readily accessible and in good condition?

    Answer: 33 CFR Part 175

    33 CFR Part 175 governs equipment requirements for recreational vessels, including carriage, accessibility, and condition requirements for personal flotation devices.

  3. A marine technician replaces a fuel tank vent fitting. Under ABYC H-24, what is required of the vent outlet to prevent fire or explosion?

    Answer: The vent must terminate outboard and away from ignition sources, with a flame arrester screen

    ABYC H-24 requires fuel tank vents to terminate outboard in a location away from ignition sources and to be fitted with a corrosion-resistant flame arrester screen.

  4. Under EPA Tier 3 marine engine emission standards, which pollutant has the most stringent new reduction requirements compared to Tier 2?

    Answer: Particulate matter (PM) and NOx combined

    EPA Tier 3 standards for marine diesel engines significantly tightened combined NOx + PM (particulate matter) limits compared to Tier 2.

  5. When testing a marine fuel system for leaks after service, which method is prohibited by ABYC and fire codes?

    Answer: Using an open flame to search for leaks

    Using any open flame to detect fuel leaks is strictly prohibited because flammable vapor can ignite instantly, causing fire or explosion.

  6. Which document must accompany a vessel when it is towed on US highways and also satisfies USCG documentation requirements?

    Answer: State registration certificate or USCG Certificate of Documentation

    A state registration certificate or USCG Certificate of Documentation serves as both the legal ownership record and satisfies highway towing identification requirements.

  7. What is the purpose of the USCG's Alternate Compliance Program (ACP) for inspected vessels?

    Answer: To allow vessels to meet USCG safety standards using recognized industry classification society rules

    The ACP allows eligible vessels to demonstrate compliance with USCG safety standards by following recognized classification society rules (e.g., ABS, DNV) as an alternative to direct USCG oversight.
