I think it may be significant that it's a treeless island. Can't use wood/sticks to help determine your latitude with a rudimentary sextant. That would also make it hard to determine noon with out being able to get a reasonably tall shadow.

Why it's included that it's a treeless island may be significant. Where would one find a treeless island in a moderate climate?

Odd that salt water is brought up too. Seems sort of like a 'DUH'. But something may be there.
I don't live in the middle of nowhere, but I can see it from here.
