HELP! Cleaning the boat after the Delta

Hey WW,
I just wanted to get some input about keeping the boat clean during our time at the Delta and after we take the boat out. We are going to Discovery Bay for a week and will have the boat in the water at a dock. Its never been in saltwater and I just wanna get some info before we head up there. Is there anything I should do as far as corrosion prevention when its in the water? What about after? Just hose it down real well is all I know about but is there any other tricks and tips! Thanks
