I thought the boom only occurred when the plane breaks the sound barrier but not during supersonic travel. Why couldn't the plane go over the ocean, accelerate to supersonic and then start flying to the other coast?

The plane is constantly breaking the sound barrier. The boom is what you hear and feel when the shockwave reaches you.
