A vessel may not exhibit two red lights in a vertical line when it is not restricted in its ability to maneuver. The display of two red lights in a vertical line is typically reserved for vessels that are constrained by their draft or are otherwise restricted in their ability to navigate. In situations where a vessel can maneuver freely, it should instead display the appropriate lights for its specific operational status, such as a single all-round white light or other signals as per the International Regulations for Preventing Collisions at Sea (COLREGs).
If you are moving......green to starboard (right) red to port (left) white to aft (rear).If you are anchored......white all around.Rule 26Fishing Vessels(a) A vessel engaged in fishing, whether underway or at anchor, shall exhibit only the lights and shapes prescribed by this rule.(b) A vessel when engaged in trawling, by which is meant the dragging through the water of a dredge net or other apparatus used as a fishing appliance, shall exhibit;(i) two all-round lights in a vertical line, the upper being green and the lower white, or a shape consisting of two cones with their apexes together in a vertical line one above the other; a vessel of less than 20 meters in length may instead of this shape exhibit a basket;(ii) a masthead light abaft of and higher than the all-round green light; a vessel of less than 50 meters in length shall not be obliged to exhibit such a light but may do so;(iii) when making way through the water, in addition to the lights prescribed in this paragraph, sidelights and a sternlight.(c) A vessel engaged in fishing, other than trawling, shall exhibit:(i) two all-round lights in a vertical line, the upper being red and the lower white, or a shape consisting of two cones with their apexes together in a vertical line one above the other; a vessel of less than 20 meters in length may instead of this shape exhibit a basket;(ii)when there is outlying gear extending more than 150 meters horizontally from the vessel, an all-round white light or a cone apex upwards in the direction of the gear.(iii) when making way through the water, in addition to the lights prescribed in this paragraph, sidelights and a sternlight.(d) A vessel engaged in fishing in close proximity to other vessels engaged in fishing may exhibit the additional signals described in Annex II to these Regulations.(e) A vessel when not engaged in fishing shall not exhibit the lights or shapes prescribed in this Rule, but only those prescribed for a vessel of her length.
Inland or International? Pushing, pulling or pulling alongside? Inland Lights and Shapes Rule 24 (c) A power driven vessel when pushing ahead or towing alongside, except as required by paragraphs (b) and (i) Covers composite units) of this rule, shall exhibit: (iii) Two towing lights (yellow) in a vertical line. (i) Notwithstanding paragraph (c), on the Western rivers (except below the Huey P. Long bridge on the Mississippi River) and on waters specified by the secretary, a power-driven vessel when pushing ahead or towing alongside, excepts as paragraph (b) applies, shall exhibit: (i) sidelights; and (ii) two towing lights (yellow)in a vertical line.
A vessel displaying sidelights, a sternlight, and two all-round lights in a vertical line is typically a power-driven vessel that is 50 meters or more in length. The two all-round lights indicate that it is engaged in fishing or another specific activity, such as towing or dredging. This configuration helps other vessels identify its activities and navigate safely around it.
It is the distance of a vertical and longitudinal planfrom the center line of the vessel
Shapes that have a vertical line of symmetry are those that can be divided into two mirror-image halves along a vertical axis. Common examples include rectangles, squares, and certain types of triangles, such as isosceles triangles. Additionally, many letters of the alphabet, like A, M, and T, exhibit vertical symmetry. Essentially, any shape that looks the same when mirrored along a vertical line possesses this property.
A vertical line!
WHY THE LINE X=4 IS A VERTICAL LINE.
A horizontal line is perpendicular to a vertical line.
A vertical line has an undefined slope. For the line to be parallel to a vertical line, the slopes would have to be the same. Therefore, the line parallel to a vertical line also has an undefined slope.
A horizontal line is a line perpendicular to the vertical.
all vertical lines are parallel to waht type of line?
its a line that is vertical and a symmetry
