She currently is in an expensive marina.
What's your definition of expensive and how far south do you intend to go?
Getting a 35 ft liveaboard slip in S. Calif. in a month on a budget may be harder than sailing to Portland (which I'm not recommending).
Slips may be available in Ventura and Channel Islands they have been expanding/remodeling. Deep in San Diego near Chula Vista may have some available at slightly lower pricing. Wilmington/ San Pedro used to have some reasonable marinas but I've heard they've been closing.
My 30 foot slip in a new marina in Alameda was $300/month, my 40 year old 30 ft slip in Dana Point is $503. Location costs.
Check the website for The Log newspaper, they'll have a link for their annual guide to slips and marinas, everyplace is listed there. Better start calling now to find a slip by October.
Otherwise, Ensenada maybe? I know commercial guys that take their boats to Mx for work in the off season, but those are big fishing boats.
Zeehag, Aren't you in ensenada?
