What CaGuy Said...
... in addition to what he said, the harbormaster responds to ch 09 around the island except for Avalon which, if I recall correctly, is ch 12. They usually won't respond until you are in the fairway. So, get a visual on them, and hang out around the first row of moorings and await them to come to you. You can usually see the patrol boat easily, grey in most of the harbors except Avalon where they are red. If you don't see them, call on the appropriate channel. At Isthmus harbor, this time of year, you will likely be asked to pick up the mooring backwards so that you are bow-out. Be careful of weather; watch out for Santa Ana wind conditions brewing. Cat Harbor on the back side is all weather, but add an hour and a half to the six you can expect to Isthmus. If you sail over, stay away from the Palos Verdes peninsula cliffs or you will be in no wind. It's typical to motorsail until you are about clear of the PV bouy and them set sail as the wind clocks around. If you are new to the area, one note of caution: stay seaward of the El Segundo bouy marking the tanker moorings. You will see people sailing or motoring through them; don't. I have seen two boats totalled who hit the pipeline that sometimes floats near the surface. Also, take care to avoid a rock outcropping off the end of PV and one between Cherry Cove and Howlands' Landing in Catalina. Enjoy the trip, the kids will love it, it's addicting. Rick D.
