Over summer when the EAC runs strongly down the
continental slope, I work wider out on the seamount
chain. The weather is also more stable and predictable
to be 180 nm off shore.
In winter when the current slows down, I work the
shelf area. There are canyons all around the coast
and most occur offshore from major rivers. Canyons
are where ancient rivers cut through the Earth’s
crust in an past geological age. Sediment has
filled in most of the river bed inshore, but along
the slope, strong ocean currents prevent this.
Along the 100 fathom line is also the remains of
ancient sea cliffs. Where sediment has not covered
them they exist today as a rocky terrace dropping
off to into deep water.
On some parts of the coast, it is possible to
follow this terrace for many miles.
With patience and good electronics, you can find
these areas. As it is mostly out of range of most fishermen, there are still good stocks of fish
