Sailing and Navigation Calculators:

• Bruce Number: Computes the ratio of the square root of sail area to the cube root of displacement of a sail boat
• Sail Area / Displacement Ratio: Compute SA/D ratio for sail boats.
• Displacement-Length Ratio: Computes a metric to describe how heavy a boat is in relation to its waterline.
• Capsize Screening Formula: Computes a metric to describe a boat's stability in rough seas.
• Vessel Displacement Volume: Computes the cubic feet displacement associated with the weight displacement.
• Weight of Seawater: Computes the weight and mass of a volume of seawater.
• Time to Sink: Compute the time it takes for a breach (water in) to surpass the displacement of the boat.
• Haversine Distance (decimal degrees): Compute the Distance Between two Points on the Earth (Great Circle Arc)
• Haversine Distance (Degrees, Minutes and Seconds): Compute the Distance Between two Points on a Sphere (Great Circle Arc) using degrees, minutes and seconds verses decimal degrees.
• Rhumb Line Azimuth: Computes the azimuth heading one can navigate for a path that crosses all meridians of longitude at a constant angle.
• Rhumb Line Distance: Computes the distance traveled between two points on the globe if traveled via a rhumb line.
• Correction Angle: navigation equation that compensates for air or water currents.
• Decimal Degrees: Compute decimal degree angles from degrees, minutes and seconds,[CLICK HERE].
• Nautical Travel Cost: Computes the total cost to travel a distance based on the cost rate and distance traveled.
• Travel Time between Coordinates: Compute the time to travel between two location (latitudes and longitudes) based on a average speed
• Distance to Sea Level Horizon: Computes the distance to the horizon from a specified height using a spherical model the mean spherical radius of the Earth
