Maneuvering speed, often referred to as "Maneuvering Speed (Va)," is used during operations that require the vessel to be agile, such as docking, undocking, or navigating in tight spaces. This speed allows for better control and response to sudden shifts in wind or current, minimizing the risk of damage to the vessel and ensuring safety. It is typically lower than cruising speed, enabling effective steering without risking structural integrity during abrupt maneuvers. Always refer to the vessel's specific guidelines for the appropriate use of maneuvering speed.
The V-speed that represents maneuvering speed is Va. This is the design maneuvering speed, which is the speed at which the aircraft can be safely controlled in turbulent air without risking structural damage.

Two short horn blasts from another vessel typically indicate that the vessel is maneuvering to overtake or pass you on your port (left) side. This is a signal used to communicate intentions between vessels to ensure safe navigation and avoid collisions. It’s important to respond appropriately by maintaining your course and speed, allowing the overtaking vessel to pass safely.

a vessel which keep its course and speed but with caution.
A safe speed.
A safe vessel speed is determined by factors such as sea conditions, visibility, traffic, and the vessel's maneuverability. Following speed limits set by regulations and considering the vessel's design limitations are key in ensuring safe operation on the water. It is also important to assess the potential risks and hazards in the surroundings to adjust speed accordingly.
In a crossing situation, the vessel that must maintain its course and speed (Vessel B) is referred to as the "stand-on vessel." This vessel is required to continue on its current path while the other vessel (the give-way vessel) is expected to take action to avoid a collision. The stand-on vessel has the right of way under maritime navigation rules.
slow to minimum speed
Maintain course and speed.
When approaching a mooring buoy, you should first reduce your speed to maintain control of your vessel. Assess the wind and current conditions to determine your approach angle. Once aligned, prepare to secure your vessel by either using a boat hook to grab the buoy or having a crew member ready to attach a line. Always keep a lookout for other vessels and obstacles while maneuvering.
The maximum legal speed for a vessel when passing within 150 feet of another vessel or a person in the water is typically "slow speed" or "no wake" speed, which is defined as a speed that does not create a wake. This is to ensure safety and minimize the risk of accidents or injuries. Specific regulations may vary by state or local jurisdiction, so it's important to check local boating laws for precise speed limits.
