This small volcanic island can provide a reasonable anchorage as protection from south/southwesterly
winds, a common occurrence with an approaching pacific frontal system and as a matter of fact, the author
has never experienced southerly winds that did not culminate in a frontal passage with heavy wind and
rain. Sometimes while anchored in Caleta Hassler on the east side of the island, the sea state can get
rough due to the northerly winds so the routine is to simply pick up and go around to the south side where
anchorage is reasonable. During the cruise of 90/91 the author had dropped anchor at the anchorage of
San Carlos in the early morning after being underway all day and night up from Cedros Island and while
getting the weather from the Baja net, it was announced that a frontal system approaching with southerly
winds of up to 50 kts forecasted for the area. This is enough to frighten any sailor, the next anchorage with
protection for southerly weather was Isla San Martin, 105 miles north or a turn back to the next protection
south, Turtle Bay. Exhausted or not, the author hauled anchor and got under way for Isla San Martin and on
arriving anchored in Caleta Hassler, It started raining in the early morning but the wind velocity was not
anything near 55 Kts. At that time, the author was sailing his Northsea 27 equipped with a CQR anchor
and 30' of chain spliced to 250' of nylon rode. The anchor was dropped in 30' and more than the usual
amount of scope was deployed due to the approaching storm. The storm passed during the next day and
late in the afternoon there was a wind shift to the northwest and at the time it was noticed that the anchor
rode was at a peculiar angle, it did not indicate the direction in which the anchor was set. Due to other
things that had to be done, this peculiarity was forgotten.  During the night, the author went topside to
retrieve a towel left out to dry and was somewhat startled to see the island on the horizon about the size of
a coffee cup and behind about 200 yards away was the white outlines of the beach surf. After getting the
boat underway back to the island, it was a sickening feeling to pull in the anchor rode with no anchor and
observe the frayed end of the rode chaffed by the bottom rocks. This was of course the peculiarity as
indicated above. Now, the author carried all chain for rode.

A close look at the port or south end of the island  will reveal the dark outlines of the seawall as referred to
by Charlie. Caleta Hassler anchorage is located just to the north of the seawall which is not really a
seawall at all, but a row of volcanic rocks.
ISLA SAN MARTIN
Caleta Hassler, provides shelter from
south/southwesterly weather.  When winds shift
to northwest, if necessary, pickup and move to
the south side to in front of the lagoon.
