Personal water craft to enable a user to walk on water

A water craft system, comprising:

• a ski configured to float on water and comprising a housing configured to receive a user's foot;
• and
• a propulsion device coupled to the ski and capable of floating on water, wherein the propulsion device is configured to grip the water and submerge a portion of the propulsion device in response to a force applied to the propulsion device in a direction approximately opposite a direction of motion of the water craft system and wherein the submerged portion of the propulsion device provides resistance for the user to propel the ski, the propulsion device comprising:
• a semi-buoyant float comprising a surface configured to grip the water and submerge a portion of the float in response to a force applied to the float in a direction approximately opposite a direction of motion of the ski, and
• an arm coupled to the float for attaching the float to the ski.

A water craft system, comprising:

• a ski configured to float on water and comprising a housing configured to receive a user's foot, the housing comprising:
• a raised trough including a drain for removing water from the housing, wherein the raised trough is positioned at a height between the top surface of the ski and the bottom surface;
• and
• a ramp coupled between the bottom surface and the raised trough for directing water into the raised trough in response to motion of the ski;
• and
• a propulsion device coupled to the ski and capable of floating on water, wherein the propulsion device is configured to grip the water and submerge a portion of the propulsion device in response to a force applied to the propulsion device in a direction approximately opposite a direction of motion of the water craft system and wherein the submerged portion of the propulsion device provides resistance for the user to propel the ski.

A housing for receiving a user's foot, comprising:

• a bottom surface positioned at a height below a top surface of the housing;
• a raised platform coupled to the bottom surface;
• a foot platform coupled to the raised platform at a front portion of the foot platform and configured to rotate perpendicular to a transverse axis of a ski;
• and
• a semi-elastic member coupled to the housing and a rear portion of the foot platform, wherein the semi-elastic member provides tension as the foot platform rotates.
