Only when you're outside the radius of the mass can you equate the problem to a single center of gravity. No, with moons on either side of the planet, you're going to get very large tides as the two faces closest to the moons are going to be gravity wells that the water from the sides facing away from the moons will flow into. Because gravity is a r squared force even though the moons are of equal mass, each side of the planet will be affected the most by the moon closest to it. The only place that the gravity of the two moons will cancel each other out is in the plane that is equidistant from each of them.</p></blockquote><p></p>
