New Position Calculator

Three things are needed to calculate a new position; 1) present milage from the Route Directory, 2) expected running time and 3) expected speed.

Determine the GOING FROM position in the Route Directory. Highlight that mileage, right click and COPY. In the New Position Calculator, highlight the number in the GOING FROM box, right click and PASTE (if there is no number in there, just right click in the box and PASTE).

Enter the Expected Running Time (in hours - 4.25 would be 4 hours and 15 minutes).

Enter the Expected Speed.


Click the POSITION button and the new position will be calculated.

Scroll down (or up if going southbound) the Route Directory to the mileage that was calculated and find the anchorage or position nearest to that mileage. Once the best anchorage or position is determined, go back to the Running Time Calculator to find a more exact running time.
