Dude you’re fishing the wrong waters here, most here who are capable of what you ask want to cash in on you. Your best bet would be to post on some of your local backpacker sties. Something along the
line “will be sailing down the coast from San Francisco to Oxnard, Ventura have room for 1 maybe 2 with sailing experience”
Take them out on the weekend to test their skills. You might say you’ll be staying overnight at some places of interest, you’ll need to
anchor anyway.
I recently drove from Brisbane to Townsville AU (850 miles), there was two of us and I got three backpackers from a website, two chicks and a guy. They paid 3/5 of the petrol and they were happy, saved me money I was going there anyway.
