Every day is a gift!  The weather gods have been kind during the Med
Bound fleet's first full day out of Horta, offering up light winds
and flat seas as we regain our sea legs, giving us an altogether
comfortable ride for our three yachts as we eat up the miles between
the island of Faial and Strait of Gibraltar. This morning we passed
by the easternmost of the Azores Islands, Sao Miguel, so it's open
ocean for us from here to the European mainland.

Weather, of course, is everything when one is making a passage in a
small boat, so we study the weather carefully, check many sources,
and take our best shot.  Our own secret weapon is "Weather Bob" Jones
of Ocean Marine Navigation Inc.  From his post in New Jersey, Bob
provides telephone and e-mail weather routing advice and counsel to
yachts around the world.  In return for what we consider a very
reasonable fee, Bob-who is a trained meteorologist who has been doing
professional weather routing for years-provides us a daily e-mail
report: an overview of the weather systems interacting to provide our
weather and his best estimate of what to expect in the days ahead.
Based on Bob's advice, we are bound for a waypoint at 39 degrees
north and 15 degrees west, north of the direct course to Gibraltar
and about 250 miles off the coast of Portugal.  That will add a few
miles to our trip, but Bob expects our winds to increase and move
more to the north in a few days, and taking this route should give us
an easier ride when that happens.

The case for using a professional weather router for a yacht like
ours is strong: Bob has access to far more information from his
office ashore with full Internet capabilities than I do at sea with a
very thin e-mail connection, and as a professional meteorologist he
knows far better than I how to interpret the information he receives.
As much as we like and rely on Bob, we also have a backup and
counterpoint: Ocens WeatherNet.  The learning curve for WeatherNet is
steep and it's not intuitive, but it's a rich weather resource with
real depth and breadth.  It even offers real-time information on
ocean currents based on satellite data, something I've not found
elsewhere.

Of course, none of this could happen without communications.  In the
middle of an ocean, Internet connections and cell phone networks are
nowhere to be found.  We employ an Iridium satellite phone as the
link between low-earth-orbiting satellites and our computer, using a
slow-as-molasses e-mail connection via an Ocens system specifically
designed for cruisers.  It's painfully slow, operating at a fraction
of the speed of a dialup modem, and interruptions are frequent.  At
around a dollar a minute, it's also expensive.  All its disadvantages
notwithstandng, it's by far the best solution we've found for sending
and receiving text messages at sea.

As compared with our Bermuda-Horta leg, Bluewater is riding more
comfortably now and we're making slightly better speed at lower RPMs.
That's because Med Bound chief engineer Bernue Francis and I
discovered in Horta, troubleshooting Bluewater's stabilizer problem,
that the boat had been "dragging" our port stabilizer fin through the
water at an acute angle causing considerable drag.  That extra drag
both slowed Bluewater down and caused us to burn more fuel on the
last leg.  We could have waited in Horta for a repairman to fly in
and fix the problem, but the truth is that we were ready to move on
and our ride to Horta was so comfortable that the decision to move on
was an easy one. Naiad promises to have a technician in Gibraltar
with the parts needed to make the repairs, a job that will be done
under warranty.  Last we heard, the Naiad tech would be "Naiad Phil"
who spent time on many NAR yachts.

Once upon a time, ships passing in the night depended on radar,
navigation lights and radio to determine how to pass one another
safely, but AIS adds a whole new dimension.  You've heard me sing the
praises of AIS, and here I go again.  Last night on my 2100-2400
watch our AIS picked up a Mexico-bound tanker named Ballad at about
24 miles dead ahead.  As the ship tracked towards us at 14 knots,
the predicted CPA (closest point of approach) varied between one-half
mile and 30 yards.  I spoke with the other two Med Bound yachts on
our "private" radio channel and we agreed that I would negotiate the
pass with Ballad.  Once we were within 10 miles, I called Ballad on
VHF, noted that we showed a very close CPA, and proposed a
port-to-port pass with a CPA of 2.0 miles, suggesting that Ballad
change course to the right and that our three-vessel formation would
do the same to increase the distance between us as we passed.  The
watch officer aboard Ballad agreed to my proposal and we changed
course, but I noted watching Ballad's course information that the
tanker did not.  Minutes later, a woman's voice came on the radio
from Ballad calling Bluewater.  She asked if our three vessels were
fishing and if that's why we were requesting a two-mile CPA.  I told
her we were not fishing, that we were three vessels traveling in
company, and that a two-mile CPA in deep water offshore is our normal
preference.  She rogered, and the ship began to change course.
Clearly, the first watch officer had kicked the decision up to
someone more senior and Ballad's female officer OK'd the course
change.  The pass was actually at about 1.85 nautical miles, plenty
safe.

David proposes that we shoot off some old flares tonight as
fireworks.  If we have no other ships nearby, we'll give it a try!
Have a great Fourth of July!
