Regarding bottom paint, if you don't leave it sit in the salt, I wouldn't worry about it. Mine had no issues until last year when I started leaving it on the mooring buoy for a week or more at a time.
Make sure you have good zincs on it and rinse it when done. A lot easier and cheaper than one or two coats of epoxy paint and then a couple coats of bottom paint. Of course mine is a bit larger and unable to be flipped.
BTW, I had about 9000 miles in the salt on my boat w/o any obvious ill effects. Now, however, I need to botom paint it pretty soon here.
