Certainly! Let's carefully analyze the requirements for the number of fire extinguishers that must be carried onboard power boats with installed fuel tanks between 26 and 40 feet in length.
### Step-by-Step Solution:
1. Understanding Boat Length and Requirements:
- The length of the power boat in question falls between 26 and 40 feet.
2. Evaluating the Fire Extinguisher Type:
- Fire extinguishers are classified by their type and rating, such as BI or BII.
- BI and BII are classifications that denote different sizes and capabilities of extinguishers.
3. Reviewing Multiple-Choice Options:
- Option A: None
- This option cannot be correct because boats with installed fuel tanks typically require fire extinguishers for safety reasons.
- Option B: One for every passenger onboard
- This option suggests an impractical requirement, as the number of extinguishers would vary with the passenger count.
- Option C: Either two BI or a single BII
- This option meets standard safety regulations, as it addresses the requirement accurately.
- Option D: One B I only
- This option does not fit the safety regulations usually set for boats of the given length category, as a single BI is often insufficient.
4. Determining the Correct Answer:
- Given the safety norms and standardized regulations for boats of this size (between 26 and 40 feet), the requirement is:
- Either two BI extinguishers or one BII extinguisher.
Thus, the correct number of fire extinguishers, considering the classification and boat length, is clearly outlined in Option C: Either two BI or a single BII.
The correct number of fire extinguishers required is option 3.
