A Mannum woman has been sentenced to more than two years in prison following a boat collision on the River Murray that left a young swimmer with life-threatening injuries. Amy Lohf, 44, pleaded guilty to an aggravated count of causing serious harm by dangerous driving after the incident on January 26 of last year.
District Court Judge Heath Barklay presided over the sentencing on Friday, detailing how Lohf operated a boat at approximately 6:40 p.m. While significantly intoxicated. Toxicology reports indicated a predicted blood alcohol reading of 0.17 per cent, a level the court noted would have severely impaired her decision-making, reaction times and perception.
The Incident and Judicial Findings
Court proceedings revealed that Lohf had been consuming champagne with friends prior to the incident. Mobile phone footage presented to the court captured the moments leading up to the collision, showing Lohf smiling and waving at the camera before steering the vessel. The footage also recorded passengers warning her to watch for jet skis and swans, followed by the realization that she had struck swimmers near their property.

Judge Barklay described the victim’s survival as “nothing short of a miracle” after she was struck by the boat’s propeller. The court noted that the victim, positioned five to 10 metres from the riverbank, had attempted to submerge herself to avoid the vessel when it became clear the boat would not turn.
Significance and Implications
The case highlights the severe consequences of operating maritime vessels under the influence of alcohol. Judge Barklay emphasized that while the offending occurred in a matter of seconds, the impact on the victim was profound. The sentencing reflects the court’s view that the decision to drive while intoxicated was inherently dangerous, irrespective of the offender’s prior character.

Legal Outcome
Lohf was sentenced to a term of two years, eight months, and 13 days in custody. She will serve a non-parole period of one year and four months, making her eligible for release in September of next year. While the judge accepted her expression of remorse and acknowledged that the incident was inconsistent with her character, the severity of the injuries caused necessitated the custodial sentence.
