  • Class 440, Marine propulsion
    • USPC 440/5: Hydraulic fluid drive to propel marine craft
    • USPC 440/8: Wind-driven motors: Motor driven by naturally moving air provides power for propulsion
    • USPC 440/21: Operator-powered drive: Motive force for propulsion comes from the physical effort of the vessel's occupant
      • USPC 440/22: Rocking watercraft: Motive force for propulsion comes from a to-and-fro motion of the vessel generated by the vessel's occupant
      • USPC 440/23: Fluid pump: Operator-powered hydraulic impelling means produces hydraulic pressure which acts on the surrounding water, producing motive force
      • USPC 440/24: Having reciprocating pull cable: Motive force is transmitted to a propelling means by a strandlike member moved alternately backward and forward.
      • USPC 440/25: Sliding handle or pedal: Motive force is transmitted to a propelling means by a hand- or foot-operated lever which moves within a guide means.
      • USPC 440/26: Rotary cranking arm: Device wherein the motive force is transmitted to a propelling means by means of a revolving arm or lever.
        • USPC 440/27: Plural-crank type: Device wherein the motive force is transmitted by rotating multiple offset segments of a revolving rod to a propelling means.
        • USPC 440/28: Having flexible drive shaft: Motive force is transmitted from an actuator through bendable rotating elongated means to a propelling means
        • USPC 440/29: Having endless drive member: Motive force is transmitted from an actuator to a propelling means through a continuous band around wheellike guides.
          • USPC 440/30: Chain and sprocket: Device wherein the continuous band is a chain and the wheellike guides are toothed wheels.
        • USPC 440/31: Including gear means: Motive force is transmitted from the rotary crank to the propelling means by means of interengaged toothed members.
      • USPC 440/32: Lever with connecting linkage: Motive force is transmitted by a bar that oscillates about a pivot to transmit force to a propelling means through an intermediate connecting rod.
    • USPC 440/33: Towing - Device wherein the propulsion means is a means provided to haul or pull a vessel through water
    • USPC 440/49:
