Abstract: A marine craft steering assembly comprises a rudder stock mountable on a craft for steering movements; a rudder blade mounted on the stock to partake of steering movements therewith and to swing relatively to the stock to a raised position if the blade encounters an obstruction. The blade is biased to its raised position, and a manually operable device, which may be a tiller, is cooperable with the blade for resisting swinging of the blade lower portion to the raised position and for swinging the blade from its raised position to its lowered position. The stock is releasably pivotally mountable on a craft hull and is locked in mounted position thereon by the aforesaid manually operable device movably mounted on the stock.
