Option B (possibly):
There may still be an outfit (or freelance, you assemble the deal yourself) in AZ/Mexico. Who'll truck a boat one way in between the two places, & or both.
With the Sea of Cortez
being relatively close to AZ, IIRC.
Plus, they'd likely have Far cheaper storage
options on either end, than Pacific'ish real estate in SoCal.
Option C (the "Sideways" one):
If your boat's foam/glass, it could be "disassembled", if it'll be "drydocked" long term. Meaning surgically seperating it into different pieces.
Thus making it Much easier both to transport & to store. Then, when you're ready to go sailing again. Pull out the Naval Architect's (NA) notes, & spec's, & glue her back together. Literally.
As many modern, custom, & semi-custom, multihull
designs are designed this way from page 1. When they're still an idea. Albeit, this IS a Very design specific method. Since cutting structural connectives in some boat is just Not an option. Particularly if they're non Foam/Glass boats.
