补充资料：船尾舵
古代用来操纵和控制船舶航向的装置。通常由舵叶、垂直舵杆和水平舵柄组成。在舟楫活动早期，航向靠桨操纵，尾部的操纵桨因逐渐增大桨叶面积而演变成舵。1955年广州东汉墓出土的陶船模型设有船尾舵，反映了桨的演变。东汉许慎所著《说文解字》和刘熙所著《释名》等，对舵都有解释，说明舵的应用在当时已相当普遍。到唐、宋时代船尾舵日臻完善和成熟。有的舵的舵叶面积延展到舵杆之前，使舵杆前后的水压力比较平衡，使转舵省力,称为平衡舵。有的在舵叶上开菱形小孔,使舵叶两侧的水相通，转舵既省力又不影响舵效。有的加设悬舵索和绞舵装置，以便根据航道深浅调整舵叶入水深度，舵降下可提高舵效；舵提起可得到保护。后来大型船舶增设了操舵装置，由滑车、绳索等组成。
