What Local Notices to Mariners are active on the Chesapeake Bay this week?
Worked 28s · 1 source
Three overlapping 50 nm searches of USCG District 5 notices near the upper, middle, and lower Bay. NAVCEN data last confirmed 25 September 2026 around 20:42 UTC; the searches returned 77, 62, and 43 active notices, including some outside the Bay. These are not a Bay-wide total or the full notice list. Your 5 ft draft came from the saved vessel profile.

Two of the Bay notices matter most for your 5 ft draft. There's a sunken sailboat on the western side of the main Bay at about 38°29.2′N, 076°27.9′W. And several side channels have reported shoaling shallower than your keel.

Turn a route and a vessel profile into a briefing you can read before departure: legs, constraints, notices, and open checks.
Around Me
Put the current water in context with nearby notices, conditions, and things that deserve a closer look.
Lir tells you where its data ends.
Navigation intelligence should make a captain more informed, not more comfortable than the facts allow. Lir names its sources, qualifies examples, and says when a figure needs confirmation from the chart or notice in front of you.
Use it as an instrument alongside your normal bridge procedures. You remain the final authority aboard your vessel.
