This bill establishes new criminal offenses specifically for boat operators in South Dakota. It introduces the offense of "watercraft homicide," which applies to individuals who operate a boat under the influence of alcohol, drugs, or other substances in a negligent manner that results in the death of another person, including unborn children. This offense is classified as a Class 3 felony. Additionally, the bill creates the offense of "watercraft battery," which pertains to those who cause serious bodily injury to another person, also while under the influence and operating a boat negligently, classifying it as a Class 4 felony.

Furthermore, the bill mandates that any boat operator involved in an accident that results in injury or death must immediately stop and comply with specific legal provisions. Failure to do so will result in a Class 6 felony charge. These new sections aim to enhance accountability and safety on South Dakota's waterways by imposing stricter penalties for negligent and dangerous behavior by boat operators.
