I need the Lunitidal Interval (HIGH tide) for Margate, NJ. This is right
next to Atlantic City if Margate is not listed.

Could somebody tell me this bit of information or tell me how to find it?
I'm trying to program a watch for my father (it's a gift) and I don't know
this one bit of information.

The manual says to use the time differential between the moon's transit over
the meridian until HIGH tide, not low tide.

The manual lists 11:20 for Boston and 7:30 for Miami, so I assume the
correct value for Margate, NJ is somewhere between.

I would really appreciate the help or a better newsgroup to ask in.

Thanks

Ted
