Keep it quiet or they will Jack price through roof to use the slip.
To be fair, if they see breezeblock launch they will be wanting paid more as he uses wind erosion as a launch timer!

Given choice I would haul out every time over a mooring. I have been boating for about 25 years and probably equal split on mooring/marina vs trailer. I do not miss at all going down at 1am in a gale to check boat is still floating in the bay. Then there was the 20 mins to get dinghy ready and row out, getting mooring checked bi annually for insurance, antifoul every year and in this part of the world if you couldn't get down for a few weeks the bilge pump may have drained the battery just enough so you can't start the engine when you finally get a decent day. Whilst seagull crap was always a problem I have that same problem now in my "premier storage facility" so I'm still cleaning it off.
If you have 2 people you can launch and recover in a total of 15 mins easy if trailer setup correctly and favourable slipway, that includes trailer board off, ratchet straps etc. If your slip is only usable some of the tide then that puts a different slant on things. When I use kip marina up here sometimes I need to launch or recover in middle of night or early morning so means leaving boat in marina over night so it really is entirely down to your slipway options.
