This is found at the shipwreck.

You'll have to board the shipwreck to find it.

You'll be looking for this one inside, not out in the sunlight.

You'll be looking downward.

You might have noticed that symbols 6 and 7 look very similar.

That's no coincidence.

Since you know what they look like, you'll probably solve them together.

Walk onto the shipwreck, climb up the stairs and walk across the width of the ship.

You'll find a hole where you can look down to see some orange rope arranged in a shape very similar to this symbol.

Look carefully and you'll see that you can actually draw two different paths from the same rope. Those are symbols 6 and 7.
