乱讲，想当然。规范里从哪里能来出来“总角度”的意思？Colreg
ANNEX I - POSITIONING AND TECHNICAL DETAILS OF LIGHTS AND SHAPES
(a) (i) In the forward direction, sidelights as fitted on the vessel shall show the minimum required intensities. The intensities shall decrease to reach practical cut-off between 1 degree and 3° outside the prescribed sectors.
(ii) For sternlights and masthead lights and at 22.5° abaft the beam for sidelights, the minimum required intensities shall be maintained over the arc of the horizon up to 5° within the limits of the sectors prescribed in Rule 21. From 5° within the prescribed sectors the intensity may decrease by 50% up to the prescribed limits, it shall decrease steadily to reach practical cut-off at not more than 5° outside the prescribed sectors.
(b)
(i) All-round lights shall be so located as not to be obscured by masts, topmasts or structures within angular sectors of more than 6°, except anchor lights prescribed in Rule 30, which need not be placed at an impracticable height above the hull.
(ii) If it is impracticable to comply with paragraph (b)(i) of this section by exhibiting only one all-round light, two all-round lights shall be used suitably positioned or screened so that they appear, as far as practicable, as one light at a distance of one mile.
失控灯是垂直2盏红色环照灯，masts等物体会导致扇形遮挡，只要遮挡不超过6度即可，任何船不论怎么设计都会导致遮挡。看看楼主贴出来的图纸，下面那盏灯还要受直梯的遮挡，如果算总遮挡角度，早就超过6度了。这是常见的，正常的，楼主不必焦虑。该图纸我看挺好的，没啥问题，可以认可。如果船东不大满意，那就增加距离远一点就好了，极其特殊的情况下用2盏灯当成一盏灯，依照bii.
