I confirm this is a slipway for small boats and kayaks, I personally used it yesterday. There are a few  cars nearby but don't know if access is reserved and gated. I went in by walkway stairs from the upper road with an inflatable canoe. Closed to the slipway there is a delimited area for parking the boats of a private association. There are sign panels forbidding access to motor boats but I believe that access for sails and row boats could be free.
