Navigation lights should be fitted by the manufacturer or an authorised person. Smaller boats have a number of options including bracketed or combination suction-capped lights. These types of navigation lights are available from marine dealers.
Minimum required lights
Sailboats underway
- Sailboats less than 7m and vessels under oars must have a torch or lantern showing a white light ready to display in time to prevent a collision. Sailboats less than 20m in length may combine sidelights. Stern lights in a single lantern carried at the top of the mast.
- Sailboats 7m or more in length must show sidelights and stern lights. In addition to sidelights they may show 2 all-round lights in a vertical line (red over green) that may be shown at the top of the mast, but not when a combined lantern is used.
Powered boats underway
- Powered boats less than 7m in length and whose maximum speed does not exceed 7 knots, may show an all-round white light instead of sidelights. If practical, these boats should also show sidelights.
- Powered boats must show sidelights and either an all-round white light or a stern and masthead light. Sailboats under engine power are considered to be powered boats, and must show the same lights as a powered boat. Personal watercraft are also powered boats.
Personal watercraft
- All personal watercraft (PWC) operating at night or in restricted visibility must show navigation lights.
- Navigation lights must be installed in accordance with the manufacturer's instructions. A mast for an all-round white light on a PWC should be installed in such a way it will not pose an impaling hazard. The addition of any aftermarket products to a PWC must be in accordance with the manufacturer's instructions. Must not compromise the watertight integrity of the hull.
Boats moored or at anchor
All boats at anchor or attached to a registered buoy mooring must show an all-round white light.
Sport rowing boats
Boats engaged in rowing activities (training or competition) on the Brisbane River now need to display an all-round white flashing light if they are on the water before sunrise or after sunset.
Commercial ship recognition
Daymarks and navigation lights show the activities of larger ships and many commercial and fishing ships. The following examples describe common day shapes and navigation lights. Standard navigation lights (for example port, starboard and anchor) must be shown as well as the lights used to signal particular activities.
Ships at anchor
- One black ball when the ship is less than 50m in length.
- One all-round white light when the ship is less than 50m in length.
Ships restricted in their ability to manoeuvre
These signals are used by ships engaged in activities such as servicing navigation marks, towing, underwater operations or cable laying.
- Black ball over black diamond over black ball.
Ships restricted in their ability to manoeuvre should show lights red over white over red.
When these ships are making way they should also show their normal navigation lights.
Ships engaged in underwater operations or dredging
Ships engaged in activities such as underwater operations or dredging must indicate that they are restricted in their ability to manoeuvre. If there is an obstruction on one side of the ship (such as in dredging) signals must also indicate this.
- Black ball over black diamond over black ball (to indicate restricted manoeuvrability)
plus
- black diamond over black diamond on the side where it is safe to pass
and
- Black ball over black ball on the side where there is an obstruction.
Ships engaged in diving operations should also display a rigid code flag 'A' in an area easily visible to others.
- Red over white over red indicating restricted manoeuvrability
plus
- Green over green on the side where it is safe to pass
and
- Red over red on the side where there is an obstruction.
Ships aground
These signals do not indicate distress or a need for help.
- Black ball over black ball over black ball.
Ships not under command
These signals indicate inability to manoeuvre when it is not caused by the activity of the ship (for example towing).
- Black ball over black ball.
- Red light over red light.
Pilot vessel on duty
- Code flag 'H' should be placed in area easily visible to others.
- White light over red light.
Commercial ships engaged in fishing
- Two cones with apexes together in a vertical line.
Commercial ships fishing (other than trawling) should show lights red over white when fishing at night.
Commercial ships trawling should show lights green over white when engaged in trawling at night.
All ships should keep clear of fishing ships.
