The present invention relates to a full spade rudder for a small vessel comprising: a rudder body formed in a streamlined shape to minimize the resistance of water; and an upper plate and a lower plate formed in a streamlined shape corresponding to the shape of the upper end and the shape of the lower end of the rudder body, and welded and installed on the upper and lower ends of the rudder body. A shaft hole for inserting a rotary shaft is provided on the stem side of the upper plate, and a reinforcing protrusion part is provided on both ends of the stem side of the upper plate. The shaft hole portion is reinforced through the reinforcing protrusion part provided on both ends of the upper plate which prevents a sufficient distance between the shaft hole and the rudder body from being secured due to a limited rear width ratio to stably perform a function without concern for damage to the shaft hole portion of the upper plate in an operating process.

    소형 선박용 전가동 러더에 관한 것으로, 물의 저항을 최소화하기 위해 유선형으로 형성되는 러더 본체; 러더 본체의 상단 형상과 하단 형상에 대응되는 유선형으로 형성되고, 러더 본체의 상단과 하단에 용접 설치되는 상부판과 하부판;을 포함하고, 상부판의 선수쪽에 회동축을 삽입하기 위한 축구멍이 마련되고, 상부판의 선수쪽 양측단에 보강돌출부가 마련된 기술 구성을 통하여, 제한적인 후폭비로 인하여 축구멍과 러더 본체 사이의 거리를 충분하게 확보할 수 없는 상부판의 양측단에 마련된 보강돌출부를 통해 축구멍 부위가 보강되어 작동과정에서 상부판의 축구멍 부위의 파손의 우려없이 안정적으로 기능을 발휘할 수 있게 되는 것이다.
