This amplifies the importance of maintaining a hard plot on paper chart. How
did Suzanne derive the cross track?... by hand calc or by spot check
interpolation with the GPS? Both methods are suitable.. it's the end results
that count. You'll find that current surges are typical on raised or
suddenly shallowing seafloor topography where the current is compressed and
moves at a slightly faster rate. The reason to favour the coastal [ read
shallower] areas when combating current that is against you is that the
brunt of the current will favour the deep areas and often you can encounter
a coastal eddy that actually assists your forward motion. I would maybe have
considered shorter coastal tacks than the long ones afforded by sea room if
time was an issue and the extra work involved was not impeding your
enjoyment of the sail. You'll find that options always come at a cost and
the drift afforded by the selection of open area navigation in a current may
adversely affect your ETA.
The importance of navigation and it's application is imperative to becoming
a sailor. How fast you drive a boat is of no consequence when you don't know
where you are going or how you will get there. Keep a log of every trip...
it is a valuable resource for future excursions and illustrates a respect
and proficiency in the art of sail and seamanship.
