🔍 Key Concepts

• Wake and surge effects created by a vessel moving in confined water (narrow channels) • How speed through the water changes the size and force of a vessel’s wake • The difference between conditions on the moored vessel (like mooring line slack) and the cause coming from the moving vessel

💭 Think About

• Ask yourself: What factor does the transiting vessel directly control that most strongly affects the energy in its wake? • Which option would still cause damage even if the moored vessel’s lines were perfectly adjusted and in good condition? • In a narrow channel, what makes the water move faster past nearby structures and hulls, increasing suction and surge forces?

✅ Before You Answer

• Identify which choice represents the primary initiating cause rather than a contributing factor on the moored vessel or structure. • Consider how hydrodynamic forces increase disproportionately with speed in restricted waters. • Eliminate any options that describe something that could make damage worse, but would not create strong wake or surge by itself.
