Just giving you a bonus multi for those water based adventures! BYOP.
You'll probably need a boat to get to the posted coordinates, where you will find a sign. To find the final, solve for:
N45 AB.CDE
W093 FG.HIJ
Where:
- A = How many numbers appear on the sign
- B = How many rows of text total
- C = The longest word # digits minus 4
- D = How many letters on the 4th row
- E = The longest word # digits minus the shortest word # digits
- F = The shortest word # digits
- G = How many different colors on the front of the sign
- H = How many posts hold up this sign
- I = The number of periods on the sign minus 1
- J = The last number that appears on the sign
The final will be somewhere near one of the PWAs you used to get to the posted coordinates.
You can validate your puzzle solution with certitude.
