The invention relates to an improved local structure of a racing boat. A paddle rod base of the racing boat is processed into a water entry track (A-B), a paddling track (B-C), a paddle lifting track (C-D) and a paddle return track (d-a) in a paddle base figure (2-1). The handle rotates the positioning groove 8. The foot baffle is shown in Figure 5. And a visual device figure 6 of the rotatable lens and the display screen. The paddle can move along the optimal track of the water entry track, the water paddling track, the paddle lifting track and the paddle returning track. And time and labor are saved. The foot stop is simple in structure and convenient to use and does not need to put on or take off shoes. And surrounding conditions can be seen at any time through the visual device on the sunhat.
改进的赛艇的局部结构,是将赛艇的桨杆底座加工出桨座图(2‑1)入水轨道(A‑B),划水轨道(B‑C),提桨轨道(C‑D),回桨轨道(d‑a)。手柄旋转定位槽8。脚挡图5。可旋转镜头和显示屏的可视装置图6组成。本发明可使桨叶沿着入水轨道,划水轨道,提桨轨道和回桨轨道的最佳轨迹运动。节省时间和体力。脚挡具有结构简单使用方便不用穿鞋脱鞋。遮阳帽上的可视装置能够随时看到周围情况。
