How this site works

Every rule, schedule and closure date on this site links to the official source it came from (USACE, U.S. Coast Guard regulations, or state boating agencies), with the date it was last checked.
If something can't be verified from an official source, it isn't stated as fact. Seamanship advice is labelled as the captain's advice.
No ads and no affiliate links. The captain works for a local cruise operator; see the disclosure.
