Actually they do have tides, albiet almost imperceptible. Near the equator
the oceans have very little tide. So what?
Bwahahahhahahahahahahahahhahahah! Lord but you are ignorant. What makes
you think there is very little tide near the Equator?
Simple physics proves how stupid your statement really is. The pull of
gravity from the Moon and Sun raises the tides. The pull is the even
greater at the Equator than at higher latitudes because the Earth
surface at the Equator is closer to the Moon and Sun than the higher
latitudes. Hence gravity is slightly stronger there, hence the tides
are actually higher.
Some sailor you are! Go stand in the corner.
So, the moon stays over the equator in your universe? Interesting. For
the rest of us, the Moon's orbit is inclined to the equator by 28
degrees so the moon travels "up and down" from the equator every month.
When the Moon is a its highest declination, we have our largest tides
in the mid-latitudes. Since the Moon is roughly over one of the
tropics, this is called a "tropic tide." When the Moon is over the
equator, we have smaller tides at mid-latitudes; these are called
equatorial tides. (These affects have to be added into the Spring and
Neap tides caused by the relative angle of the sun and moon to get an
almost full picture.)
The tides at the equator are also reduced by the fact that they actually
lag the moon by 6 hours. This is caused by the fact that the "tidal
wave" cannot move fast enough through the ocean to keep up. This s
called "tidal lag" and the tides at low latitudes are called "indirect
tides," while at high latitudes they are "direct tides."
Actually, the tides at any location are likely dominated by local affects.
