That was true until the 1890s when we realized that ranges were too great and ships were too fast. We started using Optical Rangefinders, plotting boards, and essentially slide rules to calculate shots. Optical rangefinders use mirrors and lines of sight to set up triangles for trigonometry.
By WW1 we were using mechanical calculators.
By WW2 we were using electromechanical calculators and starting to swap the optical rangefinders with radar.
