1. What is Sailing Time By Location?

The sailing time by location calculates how long it will take a vessel to travel a specific distance at a given speed. This is essential for voyage planning, fuel estimation, and arrival time predictions.

2. How Does the Calculator Work?

The calculator uses the sailing time formula:

Where:

• \( sail\_time\_loc \) — Sailing time in hours
• \( loc\_dist \) — Distance between locations in nautical miles (nm)
• \( sail\_speed \) — Vessel speed in knots (nautical miles per hour)

Explanation: Since 1 knot equals 1 nautical mile per hour, the sailing time is simply the distance divided by speed.

3. Importance of Sailing Time Calculation

Details: Accurate sailing time calculations are crucial for voyage planning, fuel management, crew scheduling, and meeting port arrival windows.

4. Using the Calculator

Tips: Enter distance in nautical miles and sailing speed in knots. Both values must be positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between nautical miles and statute miles?
A: 1 nautical mile = 1.15078 statute miles. Nautical miles are based on the Earth's circumference and used in marine navigation.

Q2: How accurate is this calculation in real-world conditions?
A: This provides theoretical time. Actual sailing time may vary due to currents, weather, and other factors.

Q3: What's a typical sailing speed for cargo vessels?
A: Most cargo vessels sail between 12-24 knots, with larger ships typically slower for fuel efficiency.

Q4: How does this differ from great circle distance calculations?
A: This assumes rhumb line distance. For precise long-distance sailing, great circle routes should be used.

Q5: Can this be used for flight time calculations?
A: Yes, if using nautical miles and airspeed in knots, though aircraft typically use statute miles and mph.
