Is there any web almanac for them, to

(I imagine that timing their ocultation will be hard
with my 10x50 binocular, but I would try)."
[this time for the list] There is a great little Javascript calculator on
skyandtelescope.com that displays the current positions of the moons and
upcoming occultations and other events. It's very nice. Go here:

By the way, you need much higher magnification to see occultations. That me
ans a long focal length telescope which is why the method was found to be
impractical at sea.
