Josephs works for Azure Interiors & Construction as a site supervisor, and was joined in court by his employers.
His partner and young son were not at court to support him yesterday.
Before the hearing he was heard to say: "It's a waste of time, isn't it? A waste of everybody's time."
Because his lawyer could not attend court yesterday, Josephs' case was adjourned. He was remanded at large, meaning he has no conditions imposed on him, until February 5.
Police have refused to comment on the specifics of the case as it is before the courts. But after Josephs' alleged offending they issued a general warning to all boaties - including jetskiers - about appropriate behaviour on the water.
"Police will be keeping a close eye on the beaches this summer and remind people to keep to the rules and not exceed 5 knots within 200m of the shoreline. We don't want to be dealing with any preventable tragedies on or near the water, and will take a hard line with people boating while intoxicated and not complying with boating regulations."
