    How to Calculate & Plot an Estimated Position

    Chartwork
    In this video, we talk you through how to calculate and plot and Estimated Position (EP). We have no allowed for the application of variation and deviation, so as to keep this simple. 

    There is a link in this video to a tutorial showing how to apply variation and deviation.

    PASSAGE PLANNING - WHERE DO WE START AND WHY?

    Passage Planning
    In this short video, we bring it back to basics. Once you have appraised what you need in terms of charts, pilotage books and almanacs, etc it's simply a matter of working out how long the passage is likely to be (an estimate based on the distance divided by an estimated boat speed).

    Once you have that, work out the critical tidal windows and when you will meet them and then you will be able to plan the passage based on when you want to get there and/or when you want to leave.

    Remember;
    Appraise - Plan - Excecute - Monitor
    ​
    Of course, sometimes the forces of nature will not be kind and you might need to allow for a stop at some point to allow for weather, foul tide or other issues. But if you have planned well, you will know what to expect and if you brief your crew well, so will they.

    The dance of the sun, moon, and earth: A brief overview of tidal cycles

    Tides And Currents
    Picture of moon and ocean
    Tides are the regular rising and falling of the ocean surface, caused by the gravitational pull of the moon and the sun. The phenomenon of tides is a result of the gravitational interaction between the earth, moon, and sun, and is also influenced by the shape of the earth's surface and the rotation of the planet. Tides play a crucial role in shaping the coastal environment. In this post, we will explore how tides are caused around the world, the effects of the moon, sun, and geographical features on tidal flow.
    "I have always been fascinated by the ocean, to dip a limb beneath its surface and know that I'm touching eternity, that it goes on forever until it begins here again." - Lauren DeStefano
