There are moorings for cheaper costs in
San Diego, though waiting list for best locations may be lengthy. Hear slips in south
San Diego Harbor are cheaper, Less prime areas like
commercial harbor area in LA Harbor sometimes have cheaper rates though the powers that be seem to be closing down these cheaper locations. Don't know the cost but moorings can be bought in
Newport Beach. Long Beach Marina used to be
cheap because it was partially funded by
oil money though waiting list was long.
SF Bay has cheaper rates than SoCal. Was paying $8 a foot in Alameda a couple years ago and supposedly cheaper the farther away from the bridges you get. The
Delta is much cheaper but sailing is limited, a long way to the Bay and it's HOT in the summer and COLD in the
winter.
Santa Cruz Marina has a long waiting list and hear getting a slip in Monterey is something that has to be willed to you by a rich Uncle. Same goes for Santa Barbara though I hear you can buy a slip for 6 figures.. Ventura and Channel Islands may be a deal.
I've got a slip in Oceanside for my 29' boat at $415 a month which didn't take long to get. Unfortunately bigger slips have a long waiting list at $14.30 a foot of boat length.
Then there is a trailerable boat if your subdivision reg's will allow you to store the boat at your home. A Hobie 33 is a really hot boat that you can haul around.
