German waters

The inland waterway rules for Europe apply, plus the BinSchStrO. At sea, the international channels.

  Ship to ship. With a radio aboard, report before blind stretches, narrow fairways and bridge openings.
• Sign B.11
  Radio compulsory on the stretch, on the channel the sign shows.
• 16 · 70
  At sea: Bremen Rescue Radio (DGzRS) keeps watch, 24 hours.

Inland radio needs the UBI certificate.

Nautical information channels (Revierzentralen) are on the signs and in ELWIS.

Inland waterways in Europe

Rivers, canals and lakes in the countries of the Basel arrangement (RAINWAT) follow their own radio rules.

• 10
  Ship to ship, unless the authority sets another channel.
• 16
  Distress, safety and calling only where the waterway meets the sea. Not allowed in Austria, Luxembourg and Switzerland.
• 70
  No DSC on inland waterways.
• 15 · 17
  Talk on board only.

Every radio sends your boat's ATIS code when you let go of the talk button; ATIS is required inland.

Ship to ship, port and on-board channels run at 0.5 to 1 W, switched down by the radio.

No dual watch inland. Keep to safety and navigation, except on the channels set aside for other talk.

Nautical information, lock and bridge channels are set per stretch: on the signs and in the waterway guide.
