ASA 104 BAREBOAT CRUISING CERTIFICATION
ACTUAL EXAM PREP 2026 ALL QUESTIONS
AND CORRECT DETAILED ANSWERS WITH
RATIONALES ALREADY A GRADED WITH
EXPERT FEEDBACK |NEW AND REVISED

1. A bareboat skipper is planning a week-long coastal cruise with four
crew members. What is the MINIMUM daily freshwater requirement
per person that should be factored into the provisioning plan, including
drinking, cooking, and minimal hygiene?
 A. 1 gallon per person per day
 B. 2 gallons per person per day
 C. 3 gallons per person per day
 D. 5 gallons per person per day
Rationale: The ASA 104 standards emphasize that a minimum of 2
gallons of freshwater per person per day should be provisioned for
drinking, cooking, and basic hygiene. This estimate accounts for the
realities of cruising, where water conservation is essential.
2. Which bilge pump is powered by the battery and activates
automatically without manual intervention when water is detected?
 A. Manual bilge pump
 B. Automatic bilge pump
 C. Whale Gusher pump
 D. Diaphragm pump

Rationale: An automatic bilge pump is powered by the battery and is
activated by a float switch when it senses water. This is critical for
unattended safety. A manual bilge pump requires physical effort to
operate and serves as a backup.
3. Before filling the freshwater tank from a dock, what is the MOST
important first step to ensure safety?
 A. Turn on the freshwater pump
 B. Open all faucets to vent the system
 C. Determine that the dock water supply is safe
 D. Connect the hose to the deck plate
Rationale: Ensuring the dock water supply is potable is crucial to
avoid contamination of the vessel's freshwater system. Connecting
unsafe water can lead to illness for the crew and damage to the system.
4. After using a propane stove, what should be turned off FIRST to
ensure safe shutdown and prevent gas leaks?
 A. The burner knob
 B. The main tank valve
 C. The solenoid switch
 D. The galley vent fan
Rationale: The solenoid switch should be turned off first to cut the gas
supply to the line. This allows the gas remaining in the line to burn off
completely before the burner itself is turned to the "off" position.
5. What is the functional difference between an alternator and an
inverter in a boat's electrical system?
 A. An alternator converts mechanical energy to DC electricity;
an inverter converts DC to AC

 B. An alternator converts DC to AC; an inverter converts AC to
DC
 C. Both convert AC to DC
 D. Both convert DC to AC
Rationale: An alternator, driven by the engine, converts mechanical
energy into DC electricity to recharge the battery banks. An inverter
performs the opposite role, converting DC electricity from the batteries
into AC electricity to power household appliances when shore power is
unavailable.
6. When flushing a marine head, pumping should continue until the
waste reaches which component?
 A. The toilet bowl
 B. The intake seacock
 C. The holding tank
 D. The discharge through-hull
Rationale: Proper flushing ensures waste is contained and managed
correctly by moving it into the holding tank. This prevents
environmental contamination and complies with regulations.
7. What does a freshwater pump cycling on and off with no water use
typically indicate?
 A. The battery is fully charged
 B. The water tank is full
 C. An open faucet or a leak in the system
 D. The pump is functioning normally

Rationale: This condition suggests an open faucet or a leak in the
system that needs addressing. It indicates a loss of pressure that the
pump is trying to compensate for.
8. Which critical spare part should ALWAYS be carried for the raw-
water pump?
 A. Fuel filter
 B. V-belt
 C. Impeller
 D. Thermostat
Rationale: The impeller is crucial for the pump's operation and is a
common wear item that may fail. Carrying a spare is essential for on-
the-water repairs to prevent engine overheating.
9. At approximately what engine speed should the alternator be run to
recharge batteries efficiently?
 A. 500 RPM
 B. 1000 RPM
 C. 1500 RPM or higher
 D. 3000 RPM
Rationale: Running the engine at 1500 RPM or higher optimizes the
alternator's output for efficient battery charging. Lower RPMs may
not provide sufficient charging current.
10. When sailing to windward in gusts, how can control be maintained
effectively?
 A. Bear away from the wind
 B. Feather (head up slightly) or ease the mainsail
 C. Let go of the mainsheet completely
