one of the "Two Harbors", is located on the north shore of Catalina, 6 miles
from the West End and is 12 miles west of Avalon in the notch of the stretches
from north to south. The "bay" itself contains Big Fisherman's
Cove, Little Fisherman's Cove, Isthmus itself, Fourth of July Cove and
Cherry Cove. There is a 300 foot pier that affords a depth
of about 2 fathoms at its end.
Coming from the East, the approach to Isthmus Cove is unobstructed but
West of the entrance, Eagle Reef lies about a quarter of a mile offshore
covered by about 3 feet of water. It is marked by and dark, red buoy about
100 yards to the East of it.
From North, look for Ship Rock about 1 mile north of the cove.
It is lit at night and from the channel, looks like a 66 foot high black
haystack, the top mostly white with bird guano. Be aware of the reef
lying about 120 yards South of Ship Rock and the rock at the end that uncovers
about 3 feet.
Off-center in Isthmus Cove is Bird Rock reaching to a height of 37
feet and about 150 yards in length. It's about 500 yards off the
eastern shore at the entrance to the cove. (See your charts!
That's what they're for!) The rock is covered with sand and grass and reefs
outcrop for more than 100 yards.
Harbor Reefs lie about 400 yards Southwest of Bird Rock and lie in
a Northwest direction. These small reefs are about 450 yards long and 250
yards wide. They're marked on the Southeast by a lit red buoy (Fl.
R 4 seconds) and an unlit buoy to the west and kelp patches. The
reefs show about 2 feet at low tide in places. Great place to dive, bad
place to sail.
Catalina Harbor (33o25.4'
N, 118o30.8 W) on the South side of the island is a half
a mile from Isthmus Cove by land, about 14.5 miles by sea around the West
End and is marked by the Catalina Harbor Light (Fl. 4 seconds) that sits
400 feet above sea-level on Catalina Head on the west side of the harbor
entrance. Ballast Point is on the east side of the 800 yard wide
entrance. Pin Rock is sits inside the east head of the cove
and is about 125 yards offshore and surrounded by deep water, stay clear
of it. Mooring depths are between 4 and 5 fathoms. The harbor
flattens out into shoal at the head and you should stay at least 150 yards
from the kelpline.
