I shot a question off to the FWC to ask about escambia, okaloosa, and santa rosa beach rules on PWC and beach carts and beach launching. I would like to know official rules. If they reply I will post the reply. Walton County website says only homeowner is allowed to beach launch PWC, but they are only county that has decent website.
I say just do it, worse case you get a small ticket, but most likely they will only tell you to leave. I'm assuming this is not a house with a populated public beach in front of it.
