There IS Half Moon Bay - but I don't know the availability there.
Times will vary according to size of boat. The larger the boat, the longer the time. Most marinas
have a minimum length for liveaboards.
Santa Cruz is more like 25 years and then only if you know the right people - and that is just for the slip - NOT liveaboard.
Moss Landing will tell you two years for a slip, longer for a liveaboard. When you show up in person, they will tell you actual. This is pretty typical for all marinas
Monterey is 12 to 15 years for a slip, 4 to 6 years for a mooring
(for the City owned) Liveaboard is almost out of the question. There is a private marina there, shorter wait list, twice as expensive, and liveaboard is whimsical.
Morro has a FEW slips, and mooring
. The slips and moorings are reasonably available during Summer - but you gotta be out by Winter, as most of the boats moored over in Port San Luis/Avila Winter over in Morro.
Santa Barbara - See Santa Cruz
Ventura - wait is about 2 to 3 years for a liveaboard. Only one marina regularly has slips for liveaboard (Ventura West Marina). Some of the others will on a case by case basis ... ie: boat and person must be seen and recommendations by locals they know and respect (yeah it's discrimination ... but thats life).
Channel Islands Harbor - Slips available ... liveaboard after about two years of your boat being in one of the marinas may be available - depends on which one. Cost is getting to be a major problem.
Marina del Mar and Kings Harbor (Redondo) hahahahahaa ...
San Pedro - About like Ventura - only much more expensive (except for the slums on the South side).
LA Harbor - Slips available - some even reasonable - liveaboard possible - it all depends on the boat and you, and ... and ...
Getting the idea? It gets worse.
Long Beach/Alimitos Bay - About a two year wait (depending on size) for a slip - liveaboard an additional two years or so.
Huntington - not an option for a sailboat.
- how rich are you?
- In process of refurbishing / rebuilding slips ... I don't think they are taking anything new right now. Liveaboards are 4+ year wait anyway.
Oceanside - small harbor and am not sure
Mission Bay - very few slip for boats with mast
heights of more than 35 feet.
to Chula Vista - Slip fees
are almost $25+ a foot in SD Bay to $20 in Chula - Liveaboards can be found with little wait - for a fee, of course - about an additional $200/mth.
Is that detailed enough for you?
You SURE you want to berth in Southern CA?
And you aren't trying to free yourself, if you are looking for a slip .. it is when you are looking for the best anchorage, then you are freeing yourself.
