Section 13-245-3 - Waterway markers(a) Waterway markers used on the waters of the State shall be as provided in subsections (b) and (c).(b) State aids to navigation. (1) A red buoy or sign shall indicate that side of a channel to be kept to the right of a vessel when entering the channel from the main water body or when proceeding upstream.(2) A green buoy or sign shall indicate that side of a channel to be kept to the left of a vessel when entering the channel from the main water body or when proceeding upstream.(3) Buoys or signs as described in paragraphs (1) and (2) shall normally be used in pairs and only for the purpose of marking a clearly defined channel.(4) A red and white vertically striped buoy or sign shall indicate the center of a navigable waterway.(5) State aids to navigation shall be numbered or lettered for identification. Red buoys and signs marking channels shall be identified with even numbers, and green buoys and signs marking channels shall be identified with odd numbers, the numbers increasing from the main water body or as the buoys and signs proceed upstream. Buoys and signs indicating the center of a waterway will be identified by letters of the alphabet. All numbers and letters used to identify state aids to navigation shall be preceded by the letters "HA".(6) Letters and numerals used with state aids to navigation shall be red or green, compatible with the color of the aid but of a deeper hue, block characters of good proportion, and spaced in a manner which will provide maximum legibility.(7) The shapes of state aids to navigation shall be compatible with the shapes established by Coast Guard regulations for the equivalent Coast Guard aids to navigation.(8) Where reflectorized materials are used, a red reflector shall be used on a red buoy, and a green reflector on a green buoy. On red and white vertically striped buoys, reflectors, if used, shall be red and white.(c) Regulatory markers. (1) A diamond shape of international orange with a white center shall indicate danger. The nature of the danger may be indicated by words or a well-known abbreviation in black letters inside the diamond shape, or above or below it on the white background.(2) A diamond shape of international orange with a cross of the same color within it against a white center shall indicate a zone from which all vessels are excluded.(3) A circle of international orange with a white center shall indicate a control or restriction. The nature of the control or restriction shall be indicated by words, numerals, or well-known abbreviations in black letters inside the circle. Any additional explanation may be given above or below, or both, it in black letters on a white background.(d) Guide markers. A rectangular shape of international orange with a white center shall indicate information, other than that concerning danger, a control, or restriction, which may contribute to health, safety or well-being of persons using state waterways. The message shall be presented within the rectangle in black letters.(e) Colors and composition. Letters or numerals used with regulatory or guide markers shall be black, in block characters of good proportion, spaced in a manner which shall provide maximum legibility, and of a size which shall provide the necessary degree of visibility. Where reflectorized materials are used on regulatory or guide markers, international orange reflectors only may be used to show the geometric shapes described above; any other reflectors used shall be white.[Eff 2/24/94] (Auth: HRS § 200-24) (Imp: HRS §§ 200-22, 200-24)
