Compute Time Speed Distance
BCM-06-07-AUX - Compute Time, Speed, and Distance
Fri, 03 Jan 25 Posted by: Robert Kothe
Effective Navigation requires quick and accurate calculations since a boat is a moving target with many variables. The three basic elements of a course always involve Time (T), Speed (S) and Distance (D).
Mariners use a tool for calculation often called 60DSt or D-St (Pronounced 60 “D” Street} or (D-Street)
Here is a link to a lesson and calculator. It is an excel file, so you need Microsoft excel to run it.
This video is good and correct but it does not reflect the way our manuals show it so I will include another video that mirrors the boat crew program after it.
60 D STREET: How to calculate time, speed and distance in marine navigation. (youtube.com)
This video is less polished but better reflects the boat crew program. The instructor does a better job at showing us how to extract the three formulas out of the 60 D Street pyramid.

60 “D” Street
60 D street is how we instantly remember and formulate three formulas to calculate Distance, Speed and/or Time. If you have 2 of 3 variables you can compute the rest.This video is good and correct but it does not reflect the way our manuals show it so I will include another video that mirrors the boat crew program after it.
