If two masthead lights are carried then the aft one must be higher than the forward one."
"Blue sign A blue sign or blue board is used by inland waterways vessels within the Trans-European Inland Waterway network when performing a special manoeuvre or passing on the starboard side. On navigable waterways vessels normally pass each other on the port-side, so the display of the blue sign and flashing white light signal intention to pass each other on the starboard-side. This process is known as blue boarding or historically blue flagging. The """" (CEVNI) regulations require upstream vessels operating on the opposite side to display a light-blue sign and scintillating (flashing) white light. Article 3.03 states that the"

However, port and starboard never change; they are unambiguous references that are ""not"" based on the relative directions of an observer, just as the cardinal directions of east and west do not change no matter the direction a person faces. The term ""starboard"" derives from the Old English ""steorbord"", meaning the side on which the ship is steered. Before ships had rudders on their centrelines, they were steered with a steering oar at the stern of the ship on the right hand side of the ship, because more"
"Stern The stern is the back or aft-most part of a ship or boat, technically defined as the area built up over the sternpost, extending upwards from the counter rail to the taffrail. The stern lies opposite of the bow, the foremost part of a ship. Originally, the term only referred to the aft port section of the ship, but eventually came to refer to the entire back of a vessel. The stern end of a ship is indicated with a white navigation light at night. Sterns on European and American wooden sailing ships began with two principal forms: the"

A few minutes later, the green side light of ""Empress of Ireland"" was seen apparently from 3 to 5 miles away. The green light remained for an interval, and then ""Empress of Ireland"" was seen to make a change in her course. Her masthead lights came into a (vertical) line, and she showed both the green and the red side lights. She then continued to swing to starboard, shutting out the green and showing only the red light. This light"
"Navigation light A navigation light, also known as a running or position light, is a source of illumination on a vessel, aircraft or spacecraft. Navigation lights give information on a craft's position, heading, and status. Their placement is mandated by international conventions or civil authorities. Navigation lights are not intended to provide illumination for the craft making the passage, only for other craft to be aware of it. In 1838 the United States passed an act requiring steamboats running between sunset and sunrise to carry one or more signal lights; color, visibility and location were not specified. In 1848 the"

Following the eventual new owners' rebranding into Mediterranean Shipping Cruises, her funnel was repainted white with a dark blue"

The three-barreled version's barrels were marked one green decal on the right-hand barrel, one white decal on the top barrel, and one red with a yellow center stripe decal (to indicate red or yellow flares) on the left-hand barrel. White flares were used for illumination at twilight and night, black smoke was used for obscurement, and the colored flares were used for signalling. The shells had cardboard hulls with a brass or steel base. The Imperial Navy's Type 90 is rarer"

Royal Navy ships and submarines wear the White Ensign at all times when underway on the surface. The White Ensign may also be worn on a gaff, and may be shifted to the starboard yardarm when at sea. When alongside, the White Ensign is worn at the stern, with the Union Jack flag flown as a jack at the bow, during daylight hours.

To remember this, some people use the mnemonic ""white cap, red nose"" to reflect the idea that pilots consumed a lot of alcohol while waiting for ships, thus the white captain's cap with a red nose below it. Pilot boats often also use bright colors, like flashy yellow, to make them clearly visible and distinctive in even the worst conditions. This last mainly applies to the so-called pilot tenders: the vessels"
"Nautical star The nautical star is a symbolic star associated with the sea services of the United States armed forces and with tattoo culture. It is usually rendered as a five-pointed star in dark and light shades counterchanged in a manner reminiscent of a compass rose. The nautical star is frequently encountered as an informal signifier indicating membership in the United States Coast Guard, United States Navy, or Marine Corps. The symbol recalls both the five-pointed star of the US national flag and the distinctive color pattern of the compass rose found on many nautical charts. The nautical star also"

The chief officer recommended that they steer a course more to port to avoid the flood tide carrying them farther starboard. As they spoke it was reported from the bridge that there was a light on the port bow. The captain and chief checked this sighting from the port rail.

"Sector light A sector light is a man-made pilotage and position fixing aid that consists of strictly de-limited horizontal angle light beams to guide water-borne traffic through a safe channel at night in reasonable visibility. Sector lights are most often used for safe passage through shallow or dangerous waters. This may be when leaving or entering harbour. Nautical charts (paper and electronic) give all the required information. Sectors of colored glass (or plastic) are placed in the lanterns of these lights. The light will then show these colors when observed certain bearings. Bearings referring to a sector are given in"

The PEL sector light was constructed to guide US Navy vessels into the Diego Garcia port through a narrow entrance in the lagoon. The PEL sector light produces 3.5 million candela and is visible for 10 nautical miles (18.5 km) by day. The beam with 3 colors is narrow at 1.6°. This was required because the PEL sector light was built over"
"Lateral mark A lateral buoy, lateral post or lateral mark, as defined by the International Association of Lighthouse Authorities, is a sea mark used in maritime pilotage to indicate the edge of a channel. Each mark indicates the edge of the safe water channel in terms of port (left-hand) or starboard (right-hand). These directions are relative to the ""direction of buoyage""; this is usually a nominally upstream direction. In a river, the direction of buoyage is towards the river's source; in a harbour, the direction of buoyage is into the harbour from the sea. Where there may be doubt, it"

When making this change, the masthead lights of ""Storstad"" were still visible, about miles away, and according to Captain Kendall it was intended to pass ""Storstad"" starboard to starboard and there was"

At night, coloured lights were used, in either direction, on both piers: two red lights to show that the bridge was closed, and two green to show that it was open. In foggy weather, a gong was sounded as well. Vessels passing through the bridge had to display signals too: by day, a black ball at least in diameter was to be mounted high up where it could be seen; by night, two red lights in the same position. Foggy weather required repeated blasts from the ship's steam whistle. If a black ball"
"from open water towards harbor, marks with cylindrical topmarks or square dayboards are kept to port in both regions, but colors and numbers are reversed. When lateral beacons are paired, vessels should pass between the pairing. However, beacons are also frequently placed individually. Generally, single lateral beacons are at the inside corner of a turn. Interior or exterior placement can be determined based upon the passing side (port or starboard) dictated by beacon designation. However, a current chart should always be consulted for all but the shallowest-draft vessels, as channel conditions are rarely ideal. Cardinal day beacons are used to"
