An anchor point in the context of marine ports is a designated location where vessels can safely drop anchor and remain stationary while in the harbor. While the term "Anchor Point" can refer to numerous specific locations, below is a general description of what an anchor point in a U.S. marine port typically encompasses, as well as some specifications and factors relevant to these areas.

General Description

• Location: Anchor points are typically situated within sheltered waters of a harbor, away from main shipping lanes but close enough to port facilities for easy access.
• Purpose: They serve as resting spots for vessels awaiting berth, arranging cargo, undergoing checks, or holding position due to adverse conditions.
• Facilities: They might not have specific infrastructure, but proximity to tugs, pilot stations, and boat launches can be expected.

Specifications

1. Depth: Anchor points usually provide adequate water depth to accommodate a range of vessel drafts. Typically, depths range from 10 to 30 meters (32 to 98 feet), but this varies by port and vessel type.
2. Holding Ground: The seabed composition (mud, sand, clay, rock) is critical as it impacts the holding capability of anchors. Good holding ground is a key feature.
3. Size: The area allocated varies widely but must be sufficient to allow ships to swing with changes in wind and current without colliding.
4. Mooring/Anchoring Regulations: Specific local guidelines mandate how vessels should drop anchor, the scope of chain to be paid out, and environmental protection rules.
5. Navigation Aids: Buoys, beacons, and marine lights help in identifying the anchorage area and provide safe guidance into and out of it.
6. Safety Zones: Regulations often dictate exclusion zones around anchored vessels for safety and security.
7. Communication: VHF radio frequencies are designated for mariners to communicate with port authorities, ensuring proper coordination for anchorage.
8. Weather Considerations: Most anchor points provide some natural shelter, and monitoring of local weather conditions is essential.

Examples

While generic, some U.S. locations known for prominent anchor points include:

• Port of New York and New Jersey: Various anchorage areas in Upper and Lower Bay.
• Port of Los Angeles/Long Beach: Specified anchor points outside the harbor breakwaters.
• San Francisco Bay: Multiple anchor points, including in the central bay.
• Port of Houston: Anchorage areas along the Houston Ship Channel.

Port-specific Anchor Points: Example

Port of Seattle Anchor Points

• Anchor Depth: Typically up to 60 feet (18 meters) accommodates larger vessels.
• Navigation: Utilizes extensive aids including lights, radio beacons, and buoys.
• Holding Ground: Predominantly mud and sand, suited for large ships.
• Services: Available tug assistance, barge services, and nearby repair facilities.
• Weather: Generally sheltered, but subject to Pacific Northwest maritime conditions.

Conclusion

Marine port anchor points are vital components of harbor infrastructure, providing secure and organized locations for vessels to anchor. Specifications such as depth, holding ground quality, size, and navigation aids ensure the safe and efficient management of maritime traffic. Each U.S. port may have its documented anchor areas with specific guidelines and facilities suited to the needs of various types of vessels. Always refer to local nautical charts and port authority directives for exact details.
