Report as of 12:00 AST Nov. 9 2005 - Next report in 24 hours

PART ONE FOR ALL

On day six of our passage Bluewater's crew is now so settled into the
comfortable routine of being at sea that one day segues into the next
with little fanfare. Bob's original forecasts for heavier winds and
seas have eased, and we're seeing the same moderate conditions we've
experienced right from the get-go.  Have we been lucky?  You bet!

Noon-to-noon, our daily average over the past 24 hours has been the
best of the trip: 7.375 knots.  Part of that is no doubt due to the
fact that we're much lighter because we've burned over 800 gallons
(5,600 lbs.) of fuel, but we're sure there's a current pushing us
along as well.  As Dean points out, all that water going north has to
come back sometime!

We also burned more fuel in the last 24 hours than at any other time
on the trip, 160 gallons.  This was not, as you might imagine,
because we upped the RPMs-we didn't.  Rather, we ran gensets for the
entire 24 hours-the 12 kW to cool the boat down after an experiment
aimed at cooling the engine room also heated up the whole boat, then
the 6 kW to provide cool sleeping and pilot house in this tropical
weather.

The engine room heat has been very much on our minds.  Over the past
24 hours we've exchanged e-mails with Dick Gee, VP engineering for
Alaska Diesel (Lugger), and Jim Leishman and Mike Jensen of Nordhavn.
All were very helpful.  Dick says the industry standard nominal
temperature for engine rooms is 50 deg. C or 122 deg. F, well below
what we're experiencing. Jim believes the best way to deal with the
problem is to install a pair of large Delta-T axial fans, one to pull
new "cool" air into the engine room and the other push the hot air
out.  They would go aft in the ER, using the existing ducting to port
and starboard (from the cockpit) which now brings in new air without
any fans.  Mike proposes to have a new exhaust wrapper built to go
over the existing one, something Dick Gee feels will help a lot.
Together, these sound like they ought go a long way towards solving
our problem.  Some details remain to be worked out, but I believe we
are now on a good course towards a solution.  I salute Jim and his
team at PAE for again stepping up to the plate to deal with the
problem-something they're awfully good at.

On her morning watch just before 7 am today, Judy thought she saw a
sailboat mast but it turned out to be a large brown piling, perhaps
18-20 inches in diameter jutting straight up and rising 20 feet above
the ocean surface, at position 21-36.010 N / 67-41.953 W in roughly
17,000 feet of water.  Bluewater passed it close-aboard at about 300
yards without the need for a course change.  We've puzzled over what
it was and what kept is in its vertical position.  It definitely is
one of those things that would go BANG in the night had we hit it.

We must be getting near the end of the passage.  We ran out of fresh
fruit for cereal this morning, and Judy tells us the makings for
salad are very low.  With a little luck, we're enjoy dinner in a
restaurant at Fajardo tomorrow night.

For the crew of Seabird: hope you arrived safely!

PART TWO FOR OMNI WEATHER

Bob, thanks once more for your latest forecast and the moderate
conditions you are calling for.  We are still seeing mostly SE winds
and seas, with wind speed, seas and periods as you forecast.  We will
close the loop with you shortly after arrival at Fajardo tomorrow.
Unless you see a change coming, I think we have what we need for the
balance of the trip. As always, we're grateful for your terrific
service and accuracy in forecasting.

It was most likely a water logged log, where the water is
concentrated in one end.  Such logs then float upright and in a large
swell will even go completely under for some time before bobbing to
the surface and out of the water, then back down again.

Such sightings are not common here on the US West coast, but in 50
years I have seen a couple. The biggest was about 70 feet long and 2
feet in diameter.

In a technical way smaller versions are fairly common in Puget Sound
and the inland passage behind Vancouver Island and on into Alaska.
The smaller ones are called "dead head sinkers". We generally see a
few every year. The really big ones are pretty rare, but all of them
are scary as h...
