[QUOTE=U.S. Marine (ret);79818]Mariners, I am stumped. While solving a mercator sailing problem using Bowditch II, how do you get a meridional part for a departure latitude? (Lets use the latitude out of the book: 32 degrees, 14.'7 minutes.) What table out of Bowditch should be used, and how do you enter the table, retrieve the correct figure, and thus come to the correct answer for M? The Bowditch explanation is not clear to me how to enter the table step by step get M as 2033.3 for latitude 32 degrees, 14.'7 minutes. Thank you in advance.[/QUOTE]
Use table 5. for Lat 32-14, m= 2032.5 and for Lat 32-15, m = 2033.7. Interpolate for 14.7 and you get 2033.3.
