摘要： A novel marine dock section adapted to be supported by flotation units or posts is described. A pair of horizontally spaced apart, upright, prefabricated truss-like frameworks, each comprising a pair of longitudinal tubular members preferably of rectangular cross-section secured a spaced distance apart by a plurality of vertical tubular struts extending through and double swaged into the longitudinal tubular members, are joined together by a plurality of cross members to form a planar rectangular frame which supports a wood plank decking.

摘要： A watercraft comprising a flotation body having at least one seat for a rider, and front and rear tandem skis. The rear ski is flexibly connected to the body by spring supports, and the front ski is steerable by a steering column that passes upwardly through a bushing in the front end of the body. The bushing is pivoted about a transverse axis so that the steering column has limited swinging movement in a vertical longitudinal plane. The bottom end of the steering column is pivotally connected to the front ski near the midpoint thereof, and a resilient strut extends from the forward end of the ski to the steering column just below the bottom end of the bushing. A motor is mounted within the body and has a drive shaft extending downwardly to drive a propeller located below the bottom surface of the skis. The drive shaft is pivoted for fore-and-aft swinging movement, and an adjustable link connects the bottom end of the drive shaft to the top end of the bushing. When the top end of the steering column is pulled rearwardly, the front end of the front ski is raised and, at the same time, the bottom end of the drive shaft with its propeller is swung rearwardly.
摘要翻译： 一种船体，包括具有用于骑手的至少一个座位的浮选体以及前后串联滑雪板。 后部滑雪板通过弹簧支撑件灵活地连接到车身，前滑雪板可以通过向上穿过机身前端的衬套的转向柱来引导。 衬套围绕横向轴线枢转，使得转向柱在垂直纵向平面中具有有限的摆动运动。 转向柱的底端在其中点附近枢转地连接到前滑座，并且弹性支柱从滑雪板的前端延伸到刚好在衬套的底端下方的转向柱。 电机安装在主体内，并具有向下延伸的驱动轴，以驱动位于滑雪板底面下方的螺旋桨。 驱动轴枢转以用于前后摆动，并且可调节连杆将驱动轴的底端连接到衬套的顶端。 当转向柱的顶端被向后拉动时，前滑雪板的前端升高，同时，其螺旋桨的驱动轴的底端向后摆动。

摘要： A hollow semi-rigid cigar-shaped float formed with helical external projections in the form of two corkscrew threads for use in water sport. Each corkscrew thread projection is formed from the middle of the float to an end, with one end of the float shaped as a right hand thread and the other shaped as a left hand thread. When a swimmer stands on the middle portion of the float, in water, and causes the float to rotate, the effect of the external rotation of both threads in the water, cancels any sidewise thrust of either thread. However, by shifting his position on the float so that a greater length of one thread is immersed in the water, the user may cause the float to move in one axial direction or the other, when the float is caused to rotate, in simulated log-rolling fashion. A quantity of water may be added to the internal recess of the float for purposes of ballast and the internal surface of the float may be fitted with projections to retard the motion of the water ballast, in relation to the internal wall of the float.
摘要翻译： 一个中空的半刚性雪茄形浮子，形成两个螺旋形螺旋形外螺纹外形，用于水上运动。 每个螺丝螺纹突起从浮子的中间形成一端，浮体的一端形成右手螺纹，另一端形成左手螺纹。 当游泳者站在浮子的中间部分，在水中，并使浮子旋转时，两个螺纹在水中的外部旋转的影响消除任一螺纹的任何横向推力。 然而，通过在浮子上移动其位置使得一根螺纹的较长的长度浸入水中，使用者可以使浮子沿着一个轴向方向移动，另一方面，当浮子被旋转时，在模拟日志 滚动时尚。 为了镇流器的目的，可以将一定量的水添加到浮子的内部凹槽中，并且浮子的内表面可以装配有突起，以相对于浮子的内壁延迟水压载体的运动。

摘要： A pivotable flag or signal device for water skiing is provided to warn other boats when a skier is down in the water. An over centered spring mechanism securely positions the signal device in either an operative upright position or a storage horizontal position. The signal device is mounted on an extendable shaft for varying the height of the signal device and to insure a compact storage in an inoperative position.

摘要： An auxiliary seat for a surfboard comprises a rectangular tube-form frame having two U-shaped sections telescopically connected to form the longer sides of the rectangle. A first section has a raised end for a footrest. A second section has a third U-shaped tube-form frame connected thereto to form a foldable back. Two crossmembers are fastened to the frame for attaching it to a surfboard. Expandable sleeves couple one of these crossmembers to a mast housing and the other to a casing on the surfboard.

摘要： A kayak 10 having at least one hull section 16, 18 whose volume may be adjusted to enable said hull section to be submerged by a boater for water acrobatics comprises spaced longitudinal frames 22, 24 connected to the hull section. The spacing between the frames may be varied to proscribe the configuration of the hull section over a substantial part or short segment of its length. The frames 22, 24 may be interconnected by flexible cabling 30, 32 or by a mechanical scissor linkage 48 to change this spacing and adjust the volume. Supportive framework (70, 72) is provided to prevent total collapse of said hull sections.
