Today's Challenge will test your directional skills:
Hint 1
That purple thing in the middle of the circle with the compass headings is a boat. You're the Navigator for this challenge. Navigate that boat.
Hint 2
What place is that area of land? The Fiumicino airport there is probably the best clue.
Hint 3
Despite the order of the comments on the map, do the conversion for that region before the mathematical calculations.
Solution
# Notice the numbers on the chart for ocean depths and the five lines with compass directions in degrees. Based on the numbers on the compass circle, navigate the boat 40° from its starting location and stop when you hit the number 1000. From there, navigate 90° and you'll hit the 100. Continue like that, going 80° to reach a 5, 130° to hit another 5 and finally 180° to get to the 10.
# Based on the location being Rome, convert the numbers to Roman Numerals before doing the mathematical calculations indicated. (In other words, in the second line for example, taking 100 - 2 = 98 and converting to XCVIII does not work.) You get:
 M + 1 = N
 C - 2 = A
 V = V
 V = V
 X + 1 = Y
The solution is stl.la/navvy  which is military slang for a Navigator.
