    My quick off the cuff method as I would be using at sea gives me;

    Course made good roughly;  158 degrees

    Speed over ground;  4.5 knots

    Estimated position;  N 37°12'  W 70°15'

    Course and speed by plane trigonometry, and position using declination and equation of time from Eldridge's tide tables for year 2018 (the 4 year cycle for 2022)
