[C38] tide reversals in SFB

[Philip Gay]

We had it happen to us in the San Juans a couple of times.  Once when we
were rafted next to an Islander 36.  It happened in the afternoon and we
used the dingy tied to the stern to unwrap ourselves.  We carried 60' of
chain and 200' of rope afterward and used a sentinel anchor (attached to
our main rode with a rope set about boat depth to keep the main rope near
the bottom at greater depths, when the wind was light and the currents
swinging us around.  This was a 15lb mushroom anchor with a shackle around
the main rode and a long line to adjust the distance from the anchor roller
down along the main rode.  Sound confusing but it is really a simple
concept.
