Gross Tonnage Formula:
| From: | To: |
Gross Tonnage is a measure of a vessel's total internal volume, calculated based on the ship's length, breadth, and depth. It represents the overall size of the vessel and is used for regulatory purposes, port dues, and safety regulations.
The calculator uses the Gross Tonnage formula:
Where:
Explanation: This formula provides a simplified calculation of a vessel's gross tonnage based on its principal dimensions. The result represents the total internal volume in tons.
Details: Gross Tonnage is crucial for vessel registration, determining port fees, compliance with maritime regulations, safety standards, and classification of vessels for various purposes.
Tips: Enter the vessel's length, breadth, and depth in feet. All values must be positive numbers. The calculator will compute the gross tonnage based on the standard formula.
Q1: What's the difference between gross tonnage and net tonnage?
A: Gross tonnage measures the total internal volume of a vessel, while net tonnage measures the volume of cargo spaces only (gross tonnage minus non-cargo spaces).
Q2: Is this formula applicable to all types of vessels?
A: This simplified formula provides a general calculation. For official registration and certification, more complex formulas from regulatory bodies may be required.
Q3: Why is gross tonnage important for port fees?
A: Port fees and canal transit charges are often based on a vessel's gross tonnage as it indicates the size and capacity of the vessel.
Q4: How accurate is this calculation method?
A: This formula provides a good estimate for general purposes, but for official documentation, more detailed measurements and specific regulatory formulas are used.
Q5: Can this calculator be used for both commercial and recreational vessels?
A: Yes, this calculation can be applied to various types of vessels, though regulatory requirements may differ between commercial and recreational boats.
