A helmsman must be able to see out of at least two front windows on a vessel to ensure adequate visibility for safe navigation and operation. This requirement accounts for obstacles such as potential obstructions in the water, other vessels, and the overall environmental conditions. Having visibility through more than one window helps provide a broader perspective on the surrounding area, allowing for improved situational awareness and the ability to make timely navigational decisions.

In many vessels, particularly larger ones, multiple windows are critical for redundancy; if one window becomes obscured or the visibility through it is compromised, having a second window ensures that the helmsman can still maintain a clear line of sight. This concept aligns with marine safety regulations and best practices designed to enhance safety and efficiency during vessel operation.
