    Study Notes

    Plain Sailing

    • Uses plane trigonometry with an assumption of constant speed and direction
    • Simplifies calculations
    • Does not account for Earth's curvature

    Mercator Sailing

    • Relies on Mercator Projection, a cylindrical map projection
    • Used for nautical charts
    • Advantages include easy plotting, straightforward latitude and longitude determination, and efficient distance measurement
    • Limitations include not being able to directly show great-circle distances and distortion at extreme latitudes

    Parallel Sailing

    • Traveling along the same latitude from one spot to another
    • Like following a horizontal line around Earth
    • Used by ancient mariners for navigation without accurate longitude calculations
    • They sailed along the same latitude until they spotted land then adjusted their course to their destination

    Great Circle Sailing

    • Solving courses, distances and points along the shortest path (Earth's great circle) between two points on Earth
    • Great circles follow the Earth's curvature
    • More complex due to spherical trigonometry
    • Significantly reduces voyage distances
    • Useful for long oceanic passage

    Composite Great Circle Sailing

    • Combines elements of great circle and other sailings
    • Optimizes routes by using great circles when advantageous and transitioning to other methods as needed
    • Balances efficiency and practicality
    • Nautical charts are essential for navigation and depict depths, coastlines, hazards, aids to navigation, and magnetic variations
    • Use of charts and applying different sailings is crucial for safe and efficient passage
