Thanks man, this isn't too far from my normal protocol. In the past I always gave the boat a thorough washing. sometimes even going to the DYI car wash where my boat would fit on the way home to washer down, clean the salt of the trailer etc then run the muffs when I got home. My plan long term is to keep it parked at my house with a thorough fresh water rinse after each use. It's just the season mooring I'm on the fence about.
these first 2 months I don't really have an option because I'll spend May getting the trailer fixed up anyways. It needs basically everything. tires, brakes, etc. it's just a question of keeping it in the water after June or not... IDK.
