Try talking to San Diego Boat
Movers. As, in addition to moving boats, they keep a large yard about 10 miles or so inland. Where folks can both; work
on, & store their boats longer term than in a yard, for less $.
Although I can't say for certain that with your beam, that they can move you, but it's worth a shot.
Also, query the various yards; Driscoll's, etc. in order to find out who can move a boat
of that size & width. As if you find space at a light industrial park, it may even work
out to be a better value.
I rebuilt several trimarans in San Diego
that way, a couple of decades back, up maybe 15min. south of Oceanside. And the only pricey part was moving the boats, due to their beam, & the need for a semi-specialized Lo-boy tractor trailer
Or... I could rent out your boat as an apartment or a few months... if given the marina's nod
Oh, & please fill us in on what you do find out; the good news & the bad.
