Overloading and Overpowering
Iowa law states that these dangerous operating practices are illegal.
Overloading is loading the vessel with more passengers and crew than the capacity number recorded on the Registration Certificate. It is illegal to operate a vessel if its capacity would be exceeded by the persons in the vessel plus the persons being towed on water skis, a surfboard, or similar device.
Overpowering is powering the vessel beyond the recommended carrying horsepower shown on the capacity plate installed by the vessel manufacturer.
