In restricted visibility a power vessel under way gives?

In restricted visibility, a power vessel underway must give way to vessels constrained by their draft, such as a ship in a narrow channel. It is also required to sound appropriate signals, typically one prolonged blast followed by two short blasts, to indicate its presence. Additionally, the vessel must maintain a safe speed to avoid collisions and be prepared to take evasive action if necessary. Following the International Regulations for Preventing Collisions at Sea (COLREGs) is essential in these conditions.
