Ventura does indeed have a marina (2) that allows 50% liveaboards. I was on their waiting list for a couple years (with deposit). I had forgotten about the deposit til I came back one spring and got a slip at VIM.
Two harbors 5 miles apart, one operated by the county (CIH), the other by the city (VH). In one the businesses are dying, in the other doing well. If you guessed VH as the one doing well, you're right. Make your own summations as to why.
If it wasn't for the CI national park, I sure wouldn't be here.
