This one is from MD, quoting from page 7 (emphasis mine):
"Reckless and Negligent Operation
Law prohibits negligent or grossly negligent operation of a vessel that endangers lives and/
or property. The U.S. Coast Guard for this offense may impose a civil penalty under federal
laws. The operator may be subjected to a fine of up to $5,000 and/or imprisonment for up to
one year, or both. The Maryland penalty is a fine of up to $500 for the first offense.
Some examples of actions that may constitute negligent or grossly negligent operation
include but are not limited to:
1. Operating in a swimming area.
2. Operating under the influence of alcohol or drugs.
3. Excessive speed in the vicinity of other boats or in dangerous waters.
4. Hazardous water skiing practices or Personal Watercraft operations (i.e., Jet Ski’s, etc.).
