Powerboat navigation rules, often governed by the International Regulations for Preventing Collisions at Sea (COLREGs), emphasize key principles such as maintaining a proper lookout, safe speed, and taking action to avoid collisions. Powerboats must give way to vessels under sail, vessels constrained by their draft, and those engaged in fishing with gear restricting their ability to maneuver. When two power-driven vessels are approaching one another, the "stand-on" vessel maintains course and speed, while the "give-way" vessel must alter its course or speed to avoid a collision. Additionally, vessels must adhere to navigation lights and signals, especially during nighttime or low visibility conditions.
