Introduction: The Jon Boat Weight Capacity Calculator is designed to determine the maximum weight capacity of a Jon boat based on the number of persons it can accommodate.

Formula: The weight capacity of the boat is calculated by considering the boat’s dimensions and the average weight of each person.

How to use: Input the number of persons the Jon boat can accommodate. Then, click the “Calculate” button to find the estimated weight capacity of the boat.

Example: For a boat of 12 feet length and 4 feet width that can accommodate 4 persons, the estimated weight capacity would be 2,160 pounds.


  1. Q: What are the standard dimensions of a Jon boat used in this calculator? A: The default boat dimensions considered are 12 feet in length and 4 feet in width, but these can vary.
  2. Q: Is the boat’s weight included in the total capacity calculation? A: Yes, the boat’s weight is considered along with the weight of persons.
  3. Q: Can I adjust the average weight of a person? A: Yes, by changing the “avgPersonWeight” value in the code.
  4. Q: Can I input values in metric units? A: This calculator is designed for feet and pounds; any conversion needs to be done beforehand.
  5. Q: Is this calculator accurate for different boat designs? A: It’s a general estimation and might not be accurate for boats with unconventional designs.
  6. Q: How does the number of persons affect the weight capacity? A: More persons will reduce the total weight capacity available for gear and other items.
  7. Q: Can this calculator account for extra gear weight? A: No, it only considers the boat’s weight and the weight of persons.

Conclusion: The Jon Boat Weight Capacity Calculator is a quick tool to estimate the weight capacity of a Jon boat based on the number of persons it can hold. It’s beneficial for evaluating the safety limits of a boat to prevent overloading. Always verify data for accuracy and safety concerns.
