You may have a good chance of sailing much of the way
Dog, I've never heard of anyone who sailed
from San Diego to Santa Barbara in under one month. S'matter of fact, I tried it once, spent two days tacking between Magu Rock and the east end of Anacapa for a net gain of 1 mile. Last year I tried the same thing for 6 hours for a net loss
of 3 miles.
Turn on the iron jib, autopilot, and tough it out.
