Trying to settle a debate with some other boaters. We all know that the state police can't pull us over on the highway, just to see if I'm wearing my seat belt. However, on the water, it seems like marine patrols can stop boats at random and do a safety check, looking for life jackets, flares, fire extinguisher, etc. AFAIK, these stops are not voluntary. I'm wondering how/if the courts have made a distinction between the two scenarios? Seems like the practice would have been challenged at some point, but I was unsuccessful finding any case law on the topic. Any marine cops here? What statutes/cases give you that authority?
