To solve this puzzel you must go back through the previous locations and find the obvious letters and numbers written somewhere.

1) Sargasso Sea - Nothing
2) Bermuda - 2 on box lid, 5 on plate
3) Madiera - 5 on door, 8 on wine cask
4) Tropic of Cancer - N
5) Saint Helena - 7
6) Saint Mary - 7
7) Pulau Jong - 1
8) Diomede - Nothing
9) Isla Mas A Tierras - 3 on rocks
10) Cape Horn - Nothing

Using the numbers derived from each of the locations (and the order in which they were obtained, if more than one number was obtained, such as on Bermuda and Madiera)

2 - Bermuda
5 - Bermuda
5 - Madiera
8 - Madiera
N - Tropic of Cancer
