Back in the early 1970's I was running a crew boat and my company got a contract to bring the workers out Jupiter Inlet to a dredge pumping sand onto the beach. Before I got there I checked the Coast Pilot and I read the Inlet was not a navigable inlet, used only by small local fishing boats. When I arrived with my 50' steel crewboat with a pair of 12V71's, there was a sign saying CLOSED TO NAVIGATION.
I borrowed a Whaler with a recording depth finder and charted the inlet enough to find a twisting channel for myself. The big problem was coming in at night as there were no markers. I was able to put red reflective tape on a lifeguard stand on the beach, and use it as a range marker with a streetlight in the parking lot. I just hoped every night that the lifeguards never moved that lifeguard stand!
