I've been looking into classes as well.
Checking out packages to go through ASA 104, Bareboat Charter. Most run 8 days plus.
Keeping my search to the SanFrancisco Bay and Monterey Bay areas.
Other than Monterey Bay Sailing I have only searched online.
Spoke with Captain Dutch of Monterey Bay Sailing when the wife and I went for a short cruise with him. Personable guy, laid back.
Here is a list of names I have searched,
