Pedal drive and steering assembly for inflatable watercraft and watercraft combined with same
A pedal assembly and steering assembly are disclosed for converting an inflatable, drop stitch paddle watercraft into a pedal watercraft. The pedal assembly includes a mounting plate and mounting bracket for supporting a geared drive shaft in an opening extending through the floor of the watercraft. The steering assembly includes a rudder connected to a tiller through push pull cables.
1. A drive assembly for an inflatable watercraft having an opening extending through a bottom of the inflatable watercraft, comprising:
a drive shaft comprising a first axial end and a second axial end opposite the first axial end, and an axle extending through the drive shaft from the first axial end to the second axial end;
first and second pedal support arms, wherein the first and second pedal support arms are rotatably and coaxially interconnected to the first axial end of the drive shaft and to the axle;
first and second pedals, wherein each of the first and second pedals is rotatably mounted to the first and second pedal support arms;
a propeller rotatably interconnected to the second axial end of the drive shaft and to the axle, wherein rotation of the first and second pedal support arms imparts rotation to the axle and to the propeller;
a base comprising a collar adapted to extend into the opening and a flange adapted to extend circumferentially around an upper perimeter of the opening; and
a mounting plate interconnected to a medial portion of the drive shaft and extending substantially perpendicular to the drive shaft, wherein the mounting plate is adapted to sealingly engage the base portion.
2. The drive assembly of claim 1 further comprising a mounting arm having a first end rotatably interconnected to the first axial end of the drive shaft, and a second end adapted to be detachably connected to a bottom interior surface of the inflatable watercraft.
3. The drive assembly of claim 2 wherein the second end of the mounting arm is adapted to rotate about the detachable connection.
4. The drive assembly of claim 1 wherein the base further comprises a plurality of rotatable dogs for securing the mounting plate to the base.
5. The drive assembly of claim 3 wherein the drive assembly is adapted to rotate from a first storage position having a substantially horizontal orientation to a second operating position having a substantially vertical orientation.
6. The drive assembly of claim 5 wherein in the first storage position the drive shaft does not extend through the base, and in the second operating position the drive shaft extends through the base.
7. The drive assembly of claim 1 wherein the mounting plate further comprises a window.
