Bill, > Google maps does react to "Cabo San Diego", the eastern-most point of > Tierra del Fuego, but places it 1.4 nm north of the cape itself. If this is the case, then Cook's error in his Lunar observation is large indeed. Then you are right that sea observations are much less accurate than land observations from a stationary observatory. Which is not surprising of course. In my own experience sometimes I was able to shoot excellent Lunars from a yacht (in a very calm weather), but in general my experience in shooting from a yacht is very small, and when there are substantial waves, this seems really difficult.
