Chart 923 & Chart 924 - Essential Plotting Charts
Have you ever used a Universal Plotting Sheet and tried to get high level accuracy (especially during USCG License Exams)? Chart 923 & 924 are the solution as they are much larger, and you do not need to use the interpolation scale to set up your plot or to measure longitudes. 923 & 924 eliminate much of the errors from setting up and measuring associated with the Universal Plotting Sheet and offer much greater detail which is essential for USCG Exams, especially running fixes, and other operations.
