1. What is Gross Tonnage?

Gross Tonnage is a measure of a boat's total internal volume, calculated from its length, breadth, and depth. It represents the overall size of the vessel rather than its weight.

2. How Does the Calculator Work?

The calculator uses the Gross Tonnage formula:

Where:

• \( L \) — Length of the boat (feet)
• \( B \) — Breadth of the boat (feet)
• \( D \) — Depth of the boat (feet)

Explanation: The formula calculates the approximate internal volume of the vessel based on its principal dimensions, providing a standardized measurement for maritime purposes.

3. Importance of Gross Tonnage Calculation

Details: Gross Tonnage is used for vessel registration, determining port fees, safety regulations, and classification of ships. It's an important metric in maritime operations and regulations.

4. Using the Calculator

Tips: Enter the boat'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.

5. Frequently Asked Questions (FAQ)

Q1: Is gross tonnage the same as weight?
A: No, gross tonnage measures volume (100 cubic feet = 1 ton), not weight. It's a measure of the vessel's internal space.

Q2: What's the difference between gross and net tonnage?
A: Gross tonnage includes all enclosed spaces, while net tonnage subtracts non-cargo spaces like engine rooms and crew quarters.

Q3: Why is gross tonnage important for boat owners?
A: It determines registration requirements, safety regulations, and port fees that apply to the vessel.

Q4: Are there different calculation methods for different vessel types?
A: Yes, some specialized vessels may use modified formulas, but this standard formula applies to most conventional boats.

Q5: How accurate is this calculation method?
A: This formula provides a good approximation for most vessels, though official tonnage measurements may use more detailed methods for precise certification.
