Oh yes.
Tides are caused by the gravitational pull of the Moon and, to a lesser degree, the Sun. I tried to look up a scientific explanation for why tides are less at the equator but didn't find one that is short and concise.
Having said that, in my personal experiences sailing in the tropics and in the high latitudes tides close to the equator are very little or nil and can safely be ignored. Tides and the resulting currents in the high latitudes can be very dangerous.
Because the Earth is round.
As in not flat.
FLERFers begone!
