A few weeks back one of the regular posters suggested that I check-out the marina where he keeps his boat in Rio Vista. (sorry, don't remember his name) Well, I went to their web site, liked what I saw and am going down there this weekend to see it in person. Couple of questions, though, about sailing on the delta. First, isn't the delta 'brackish' water, that is, not fresh but not really saltwater? Should I paint the bottom with anti-fouling paint or would that be a waste of time? I've only harbored the boat in freshwater before, and though she got a little 'furry' after 4 months, it all came right off with pressure washer. Will the delta water have a lot more 'stuff' in it that will grow on the hull? If I should paint her bottomsides, what would be the reccomended product? Second, my boat doesn't have radar, is that going to be a problem? Every summer we hear of accidents on the delta with one boat running into another (almost always a powerboat was at fault) so I'm wondering if radar is considered a nescessity for safety. Third, do most of the marinas have guest slips that can be used when going to their store, restaurant, etc. or should I plan on anchoring and using a dingy to get back and forth? I know these probably sound like dumb questions to most of you, but as a beginner I'm curious as to what I'm gonna need and run into as I expand my sailing horizons and move-up from lake sailing, so any info you can share would be greatly appreciated.
