Free HSC Practice Questions

10 free, exam-style National High-Speed Craft (HSC) (HSC) practice questions with answers and explanations. No signup required. Work through them below, then take the full free HSC practice test to study every exam domain.

Question 1

A high-speed craft's certification defines its 'worst intended conditions.' What do these conditions specify?

  1. The most severe sea state used as the structural design basis for survival
  2. The environmental limits within which the craft is certified to operate
  3. The point at which the craft must reduce to displacement (hull-borne) speed
  4. The maximum weather in which the craft can survive without capsizing
Show answer & explanation

Correct answer: B - The environmental limits within which the craft is certified to operate

Question 2

How do 'critical design conditions' differ from 'worst intended conditions' for a high-speed craft?

  1. They describe the calm-water trials used to certify the craft's maximum speed
  2. They are the routine daily operating limits printed in the Route Operational Manual
  3. They apply only to cargo high-speed craft and never to passenger craft
  4. They are more severe conditions used as the survival design basis
Show answer & explanation

Correct answer: D - They are more severe conditions used as the survival design basis

Question 3

A high-speed passenger craft is certified to carry 450 passengers and operates only where survivors can be readily rescued and reach survival craft. Under the HSC Code, it is classified as:

  1. Category A passenger craft
  2. Category B passenger craft
  3. A cargo high-speed craft carrying passengers
  4. A dynamically supported craft outside the Code
Show answer & explanation

Correct answer: A - Category A passenger craft

Question 4

What is the essential design feature that distinguishes a Category B passenger high-speed craft from a Category A craft?

  1. It is restricted to carrying no more than 450 passengers on any voyage
  2. It may only operate in daylight hours and in favourable weather windows
  3. It can still reach a place of refuge after damage to its vital systems
  4. It is exempt from the requirement to carry marine evacuation systems
Show answer & explanation

Correct answer: C - It can still reach a place of refuge after damage to its vital systems

Question 5

Which international instrument makes the International Code of Safety for High-Speed Craft mandatory for qualifying craft?

  1. MARPOL Annex VI on air pollution
  2. SOLAS Chapter X on high-speed craft
  3. STCW Convention, Chapter II
  4. The International Convention on Load Lines
Show answer & explanation

Correct answer: B - SOLAS Chapter X on high-speed craft

Question 6

A high-speed craft holds a valid High-Speed Craft Safety Certificate but is about to begin a new commercial passenger service on a specific route. What additional document must be in place before it may operate that service?

  1. A separate International Tonnage Certificate covering the new route
  2. A Minimum Safe Manning Document specifically endorsed for high speed
  3. An amended Document of Compliance issued by the flag State
  4. A Permit to Operate High-Speed Craft for that route
Show answer & explanation

Correct answer: D - A Permit to Operate High-Speed Craft for that route

Question 7

Under COLREGS Rule 6, which consideration is MOST decisive when a high-speed craft determines its safe speed compared with a conventional displacement vessel?

  1. The draught of the craft relative to the available depth of water beneath the keel
  2. The rate of fuel consumed by the machinery at the selected cruising speed
  3. The greatly reduced time available to detect and react to risk
  4. The comfort of the passengers seated in the forward passenger cabin
Show answer & explanation

Correct answer: C - The greatly reduced time available to detect and react to risk

Question 8

A high-speed craft closing another vessel finds the CPA and TCPA on radar reducing far faster than expected. What is the single most effective action available to the operator to restore reaction time?

  1. Reduce speed
  2. Increase the radar range scale
  3. Sound a signal and hold course
  4. Switch the ARPA to true motion
Show answer & explanation

Correct answer: A - Reduce speed

Question 9

In restricted visibility at high speed, what fundamental hazard does a high-speed craft face that a slow conventional vessel does not to the same degree?

  1. Its radar becomes markedly less able to detect small targets buried in sea clutter
  2. It is required by the Rules to exhibit an entirely different set of navigation lights
  3. It is prohibited from using GMDSS equipment while proceeding at operational speed
  4. Its stopping distance may exceed the range at which targets are first detected
Show answer & explanation

Correct answer: D - Its stopping distance may exceed the range at which targets are first detected

Question 10

As the significant wave height rises toward a high-speed craft's operating limit, what is the operator's primary means of controlling structural loads and passenger injury from slamming?

  1. Increase power to hold planing trim
  2. Reducing speed
  3. Put the sea directly astern
  4. Ballast down by the head
Show answer & explanation

Correct answer: B - Reducing speed

What's on the HSC exam

The National High-Speed Craft (HSC) (HSC) exam is organized into 1 knowledge domains. These free practice questions are drawn from across them so you can see where you're strong and where to study:

  1. Coast Guard-approved Type Rating training program competencies per 46 CFR 11.821 and NVIC 20-14
