slips

Hey guys, First post! Woo! As an introduction, I am in my late 20s and just finished up my ASA certifications. I have been chartering boats but am itching to get my own so i can alter it however i like. I take a lot of pride in ownership. My budget is on the cheap side but I understand quality...

My boat is in LA, and my wife and I are thinking of moving to SF. What is the marina situation up there. Are slips plentiful? Are they expensive? Do a lot of people use moorings? Thanks
