***Maintenance on St. Georges Bridge, C&D Canal***

Mariners are advised that an engineering firm, on behalf of USACE, will be performing maintenance on the St Georges Bridge, C&D Canal, mile 4.5, at St Georges, DE. To facilitate bridge work, the maintenance will be from March 1, 2023, from 6 a.m. to 5 p.m., 7 days a week through December 1, 2023. During work hours, a snooper will be located in and around the navigation channel reducing the vertical clearance by approximately 20 feet. Vessels who can safely transit through the reduced vertical clearance, may do so at any time. Mariners who need more than 115 feet of vertical clearance during work hours should notify the work foreman no less than 30 minutes prior to navigating through the bridge. The project foreman can be reached on VHF-FM channel 13 or (610) 842-5257. Mariners should use caution navigating through the area.

Reporting Sexual Misconduct on U.S. Vessels

***See attachment for full text***

Sexual misconduct that occurs onboard U.S. flagged vessels harms mariners, interrupts safe operations, and often leads to accidents, lost careers, and a lifetime of trauma for the survivors who endure the abuse. The Coast Guard is committed to investigating and pursuing appropriate enforcement actions for all reports of sexual misconduct on U.S. flagged vessels. This MSIB supersedes the Assistant Commandant for Prevention Policy’s MSIB 11-21 “Reporting Sexual Assaults on U.S. Vessels” issued on December 16, 2021.

The Captain of the Port (COTP), Delaware Bay, is notifying mariners of the amended anchorage regulations, specifically 33 CFR 110.157, paragraphs (a)(18)-(20) for the Delaware Bay and River, and adjacent waters, which established two offshore deep-water anchorages. The establishment of these two anchorages is to improve navigation safety by accommodating recent and anticipated future growth in vessel size and the volume of vessel traffic entering the Delaware Bay and River, and to preserve areas traditionally used or needed for anchoring.

COVID-19 Safety Requirements in the Maritime Transportation System: Change-5
***see attachment for full text***

On April 18, 2022, the US District Court, Middle District of Florida, vacated the Centers for Disease Control and Prevention (CDC) mandate for mask wear in airports, train stations, and other transportation hubs as well as on airplanes, buses, trains, and most other public conveyances in the United States, including vessels. Per this ruling, the CDC has declared that the mandate is no longer in effect. Federal agencies are reviewing the court’s decision. In the interim the Coast Guard will not enforce the directives requiring mask use on public transportation and in transportation hubs. CDC continues to recommend that people wear masks in indoor public transportation settings.
Vessel and sea port operators are encouraged to monitor the CDC website at for the most up to date guidance. The CDC has published an updated list of frequently asked questions (FAQs) that can be found at Public Transportation. The Coast Guard has also published additional guidance that can be found at the FAQ web page.

This Marine Safety Information Bulletin (MSIB) is intended to highlight several recent cyber events involving increasingly sophisticated malicious email spoofing techniques within the Marine Transportation System (MTS). The types of reported spoofing attacks included impersonating Coast Guard ( email addresses, and Coast Guard industry communications regarding Area Maritime Security Committee meetings. In one case, the opening of a malicious file caused a network compromise that resulted in additional spoofed emails that were sent to MTS port partners. These types of attacks have potential cascading consequences, and impacted organizations should immediately notify all affected stakeholders and local authorities. Coast Guard units along with Maritime Transportation Security Act (MTSA) regulated facilities and vessels should be on high alert and remain vigilant for similar cyber threats within your areas of responsibility.

In an effort to improve response times and align with other Captain of the Port (COTP) zones, an updated Sector Delaware Bay Navigation Safety Equipment Deviation Request form, otherwise known as a Letter of Deviation request, is being released for use within the Delaware Bay COTP zone. Mariners are asked to use this updated form when requesting a deviation from navigation safety equipment requirements, per 33 Code of Federal Regulations (CFR) §164.55. As a reminder, making such a request does not relieve the vessel of the requirement to report inoperable equipment on a Notice of Arrival per 33 CFR §160.206.

Reporting Requirements for Vessels with Inoperable Navigation Equipment

U. S. Coast Guard Sector Delaware Bay has noted an increase in the number of vessels failing to report inoperable navigation equipment prior to transiting through the Delaware Bay Captain of the Port (COTP) zone. As a reminder, all self-propelled vessels of 1600 or more gross tons when operating in the navigable waters of the United States are required to report inoperable navigation equipment as required by Title 33 Code of Federal Regulations (CFR) Part 164.

Non-operating equipment must be reported to each COTP zone which a vessel will transit through. For example, vessels transiting to and from Baltimore utilizing the Chesapeake and Delaware Canal and passing through the Delaware Bay enroute to and from sea are required to report inoperable equipment to Sector Delaware Bay. A vessel is required to make this report regardless if they call upon a port or anchorage within the Delaware Bay or River. On a case-by-case basis, the COTP may impose restrictions (commonly known as a Letter of Deviation) on the vessel with inoperable equipment to ensure the safety of the port and vessel.

Submission of an Advanced Notice of Arrival (ANOA) does not meet the reporting requirement for inoperable equipment. Vessels are required per 33 CFR 164.53 to report inoperable navigation equipment including radar, radio navigation receivers, gyrocompass, echo depth sounding device, AIS, Electronic Position Fixing Device, ARPA, and primary steering gear.
