发明名称 Rowboat with permanent submersible wheels
摘要 A rowboat with a pair of permanantly mounted wheels installed in the middle of opposed sides of bottom of boat. A pair of wheel wells isolate the wheels from interior of boat, thereby removing most of the wheels from exposure to turbulance and drag. The wheels are supported by and rotate around an axle. The axle is cradled in a recess molded into bottom of boat. A pair of skegs or keels are molded into boat and aligned longitudinally with direction of wheel travel. Fastened to bottom of skegs is a replacable plastic wear resistant tube split in half longitudinally. Thus providing a rowboat that is easy to move on land as well as water and has significant wear resistance on bottom.
