Bob, I was wrong on yesterday's noon latitude; it should have read
34-03.1 N.  Sorry!

Bluewater passes the halfway point in this passage later today.
Yesterday afternoon was idyllic-one of those lovely days at sea
you're always hoping for: sunny weather, flat seas, excellent boat
speed, and good progress.  Then the day began to dissolve into one
that we'll long remember but don't care to repeat: strong head
currents slowing our progress at times to less than 5 knots, and
meeting a sizeable part of the Newport Bermuda Race fleet head-on in
squally conditions.  We spotted our first three racing yachts shortly
before 1800 and in the next 12 hours passed an estimated 50 Bermuda
racers, changing course dozens of times.  We're advised that the
fleet split into two parts, one going east to ride the meander and
the other west to ride the cold eddy; it's our guess that the racers
who went east are out front because those we met overnight were
having slow going-one of them saying he was down to 2 knots and
having a hard time steering.

We say goodbye to Summer Skis in an hour or so as we make our turn to
the north for Maine and they remain on the rhumb line into Newport.
We all agree that it's been enjoyable to share the passage. We all
appreciated having a buddy boat last night to help one another find
our way through the Bermuda fleet in squally conditions that made
picking radar targets a lot like trying to separate out individual
snowflakes in a blizzard.  Fortunately, picking the racers up on
radar was far easier than getting an eyeball on their dim running
lights-though the squalls didn't help either chore.  And there was
the usual confusion: we'd make a radio call to the yacht four miles
from us by latitude and longitude, only to have another answer
thinking we were calling him-then it would take several minutes to
sort that out and get back to trying to contact the nearest one; many
yachts simply didn't answer the calls leaving us to guess their
intentions, not always easy in the slow-going for them-many had
difficulty maintaining steerage so we'd see sometimes see a racing
yacht's red light, then his green, then nothing.  The potential for
danger was definitely there, but common sense, good humor and
courtesy prevailed and it all sorted itself out.  We were reminded
that AIS is a wonderful tool for avoiding large ships, but last night
it was useless in dodging the sailing yachts.  We crowned our Furuno
ARPA radar as king for a night for the great job it did for us
sorting out the threats from the also-rans and squalls.

Last night offered a good tutorial for us on navigation lights.
Coast Guard requirements say navigation lights (other than white
"masthead lights")-even for vessels up to 65 feet-need only 2 NM
visibility.  For us, two miles is too close at night!  Almost
invariably, the lights on these racing boats seemed designed to meet
the minimum legal requirements rather than to be seen at sea at
night.  The tricolor lights at the top of the mast were visible for a
much greater distance than the low-down side lights-often twice as
far-yet only one boat in five had a tricolor burning at the mast top.
Moreover, by Sunday night the racing yachts had been underway for
over 24 hours and many of their batteries were no doubt low, further
reducing light visibility.  One skipper pleaded no engine and turned
on his lights only after we called her by radio!  If the name of the
game is being seen at sea offshore in the darkness, most of the
Newport Bermuda Race yachts we passed barely scraped by.

About 9 this morning we spotted what appeared to be a great white
sail on the horizon.  As we approached, it became apparent that what
we were seeing was a large white square rigger.  Then we noticed that
it had a bright orange stripe across the bow; it was the Coast
Guard's training ship Eagle, under full sail-what a sight!.  Jim
spoke with them, and we took a few pictures.  Even with all sails
drawing in 12 knots of wind, Eagle was making good only five knots!

Because of our reduced speed overnight, our ETA Portland is suspect;
we may bite the bullet and slow down to arrive Thursday morning.  We
continue to be comfortable and boat speed is on the increase again,
currently just above 7 knots.  We may even get a push when we cross
the Gulf Stream later today.

All is well.
