What is the least depth at Terminal 18, Berth 2, Seattle?

The least depth at Terminal 18, Berth 2, Seattle being 49.4 feet indicates that this depth is the minimum required to safely accommodate vessels that may use this berth without risk of grounding. In maritime operations, understanding the depth of berths is critical for ensuring that ships are able to dock safely, particularly for larger vessels that have deeper drafts.

The significance of this measurement lies in its role in planning and scheduling maritime activities, where informing shipping schedules and vessel arrangements relies on accurate depth data. The depth of a berth also impacts the types and sizes of vessels that can be serviced, which is crucial for terminal operations and logistics.

Choosing a depth such as 49.4 feet over options like 48.0 feet, 50.5 feet, or 45.5 feet accurately reflects the need to consider sufficient clearance for various vessels while also accounting for potential changes in water levels due to tides or other environmental factors. This depth provides enough margin to ensure vessel safety and operational efficiency at that terminal.
