Yep. Everything is in focus with the long lens.

Nope. With a long lens, the depth of field is narrowed. That means
that if the foreground is in focus, the background will be =more= out of
focus than it would be had one used a short lens. There are of course
other variables (f-stop and film format) but all else equal, the long
lens narrows the depth of field and makes things seem "on top of each
other".

You can also get a sense of relative distance if you know the sizes of
the plane and boat in question, and measure the image.
