Please learn how to reserve and pick up a mooring before you go to Catalina, and realize that 30 knots away thru two commercial shipping lanes with car carriers or container ships the size of a four story apartment buildings can require stamina and skill, as well as luck.
The Channel Islands are best accessed from Ventura or Channel Islands harbor since Anacapa's only about 11 knots off. They are very rustic and require landing permits and very good anchoring skills since there are no moorings or dockage. The weather as you get closer to Point Conception becomes much like the Pacific Northwest offshore.
Offshore Santa Ana winds will make the east side of the islands lee shores so know how and when to anchor securely. Like any popular destination there are varying degrees of seamanship in the areas of Avalon, Cat Harbor and the coves that can provide endless excitement and entertainment.
