It is unlawful for any person to operate or cause to be operated a vessel in a reckless manner. For the purpose of this section “in a reckless manner” means either (1) in willful or wanton disregard of the rights or safety of others, or (2) in a fashion that creates a substantial and unjustifiable risk of harm to person or property. A substantial and unjustifiable risk is a risk of such nature and degree that the conscious disregard of it or a failure to perceive it constitutes a gross deviation from the standard of conduct that a reasonable person would observe in a similar situation.
