General Announcements

Opsail 2012:
The final event for Norfolk Harborfest/Opsail 2012 on Tuesday, June 12 will be a parade of ships leaving Hampton Roads and sailing up the Chesapeake Bay to Baltimore. They are expected to pass Smith Point at the mouth of the Potomac around sunset on June 12. Baltimore's Sailabration will take place June 13-19 (http://www.starspangled200.com/baltimore). The next event will be in Boston June 30-July 5, for the War of 1812 Bicentennial Commemorations. Connecticut will host the final event from July 6-9 (http://www.opsail2012ct.org/)  in New London/Groton. Check  http://www.opsail2012.com/ for general information on Opsail 2012. There will be local regulations for each event. Some are given below where the Coast Guard has published information in the Local Notices to Mariners. Check the last East Coast Alert, May 25, 2012, (https://www.boatus.com/cruising/tomneale/alert.asp) for details on Baltimore's restrictions.

Lat/Long Positions in Alerts
Lat/Long positions derived from Google Earth will be given for significant places in the Alerts, such as bridge locations. These will be in italics, and in the following format: xx.xxxxxx°-xx.xxxxxx° for locations new with this alert. Where a Lat/Long position is copied from a USCG Local Notice to Mariners (LNM) or from the Light Lists, it will be in whatever format the Coast Guard has used which varies between districts and LNM and Light List writers, and will be in plain text, rather than italics. Some positions are approximate. We do not provide this information for navigational purposes and it should not be used as such.*

*Italicized text above and below indicates our comment or paraphrase.  Plain text is copied from the Notices to Mariners or other sources given.

Summer Celebrations:
Be prepared for the usual waterway restrictions and bridge closures (for vessels) for Fourth of July Fireworks displays in many cities and historical locations all over the East Coast. There are too many for us to list. Most involve closing of usually opening bridges to accommodate traffic before, during and after fireworks displays. There will also be restricted areas where vessels will not be able to enter due to danger from fireworks. Check locally if you plan to be on the water for any of these displays. And be safe. We have included below only one notice because it involves a day-long restriction for the area around the National Mall.

NOTE: Since the Southern Snowbird season is about over and many are in the Chesapeake or heading further north, we have changed the order of the alerts to begin with the northernmost USCG District 1.  District 5 follows and then District 7. Within each District, alerts will generally be in a north to south list. Important "Attention Snowbirds" Alerts will be included in General Announcements when they first become available. We try not to repeat an alert, unless the event has not taken place yet or unless we feel that it is particularly noteworthy or would cause delay or danger for the general boating public, such as a reduced vertical clearance at an ICW bridge or a bridge closure or other restriction. While we use the USCG Districts as a basis for geographic division, much of the information comes from other sources than the USCG weekly Local Notices to Mariners.

US/Canadian ENC Changes:
To comply with internationally agreed upon practices, Canada and the United States have been eliminating overlapping coverage of Electronic Navigation Charts (ENCs). Changes will soon take effect in the Bay of Fundy/Gulf of Maine. This new ENC coverage scheme will result in each country changing their areas of coverage, so that only one country's ENC would be available for any given area at a particular scale. To view these new limits go to http://www.nauticalcharts.noaa.gov/mcd/enc/USCanadaBorder.htm and click on Atlantic. These changes come into effect at 0000 Coordinated Universal Time (UTC), on July 26, 2012. (First District LNM 20)

Parades of Sail and Norfolk Harborfest/Opsail 2012 Celebrations, June 6-12:
Local Knowledge: This is not a good time to make a quick passage through the last few miles heading north on the AICW or through the Hampton Roads cities. It is a wonderful celebration, but transient dockage will be basically nonexistent (and exceptionally expensive) in the Norfolk/Portsmouth (36.842709° -76.300259°) area, and the only anchorage there will be filled with rafted celebrants, especially over the weekend. There will be three parades of sail, Wednesday, June 6, Friday, June 8, and Tuesday, June 12 (heading up the Chesapeake Bay). Expect restrictions on recreational vessel traffic during various times. Listen for these on VHF 16 if you are passing through the area. Checkhttp://www.festevents.org/mini-site/norfolk-harborfest/parade-of-sail for the schedule of events.

Congestion at Great Bridge:
