Well, what about salt water lakes?  Im aware of at least 2 spots where
the low tide level is below a sand bar, which causes a salt lake to
form, so your idea of the coastline depends on whether its high tide and
the sand bar is covered (meaning the lake is navigable) or the bar is
exposed in which case its a lake where you cant navigate back into the
ocean.

Just to throw a spanner in the argument.
