COLREG’s Annex I 3(a)
(a). When two masthead lights are prescribed for a power-driven vessel, the horizontal distance between them shall not be less than one half of the length of the vessel but need not be more than 100 metres. The forward light shall be placed not more than one quarter of the length of the vessel from the stem
避碰要求两桅灯水平距离大于1/2船长,又要不大于100米,对于总长超过200米的船舶,这个不是会互相矛盾吗?求大神解释!!
