Chapter 4: The Legal Requirements of Boating
Other Equipment

Diver Down Flag

Scuba divers or snorkelers display a flag to mark their diving area. Vessels not engaged in diving should stay well clear of areas displaying the “diver down” flag or vessels displaying the “code flag Alfa.”

• Diver down flag: A rectangular red flag with a white diagonal stripe displayed from a float during diving operations.
• Code Flag Alfa: A blue and white International Code Flag A (or Alfa flag), flown from a vessel restricted in its ability to maneuver. This flag indicates that a vessel is involved in a diving activity.

Marine Events

Permits are required for some water events. All tournaments, regattas, races, parades and exhibitions must be authorized by the Delaware Department of Natural Resources and Environmental Control (DNREC). An application must be made to the DNREC at least 30 days before the event.

Boat Ramps and Mooring Facilities

These regulations apply to those using a boat ramp, parking lots, seawalls, or other mooring facilities administered by the DNREC’s Division of Fish and Wildlife.

• Use of these facilities is on a first-come, first-serve basis.
• Vessels must not be left unattended and disabled vessels must be cleared as soon as possible. Vessels or vehicles left unattended more than 48 hours without notification of the Division of Fish & Wildlife Enforcement Section will be removed as abandoned at the owner’s expense.
• Seawalls and other mooring facilities may be used only while loading and unloading vessels or while waiting to use boat ramps.
• You may not moor your vessel or conduct repairs of your vessel in an area which interferes with boat ramp traffic. Ramp areas must be kept clear at all times for vessels being launched or recovered.

Local Regulations

Some waterways in Delaware may have special regulations such as speed or horsepower restrictions. Check with the governing body of the county or municipality where the waterway is located before going out.
