GK

At sea 635 miles south of Bermuda.

Date and time: Thursday, May 18, Noon AST
Position:  19-05.5 N 64-26.8 W
Course:  016 deg. M
Present speed:  7.5 kts.
Distance made good since departure: 180 NM
Distance made good noon to noon: 154 NM
ETA St. Georges, Bermuda: 0900 Monday, May 22
Conditions: Wind SSE 10 kts, seas SSE 3-4 ft., mostly clear, air
temp. 82 deg. F, sea temp. 82 deg. F, barometer 1029.5 mb falling
slowly

You may have noticed that in yesterday's report I got the day wrong:
we are now cognizant that today (not yesterday) is Thursday!  As
usual, it takes about 24 hours offshore for us to settle into a
comfortable routine, and the crew Bluewater seems to be there now-our
bodies are adjusted to the motion, we're well fed (thanks, Judy!) and
well rested.  All systems aboard are functioning normally and our
regular visits to the engine room (which Dean calls the Bat Cave)
lazarette confirm that the machinery seems happy.

Is there something about this boat that seeks and finds current on
the nose?  Starting about sunset last night our boat speed dropped
from our usual 7+ knots to an average of 6+ knots and that continued
through daybreak this morning.  Our knotmeter indicated that we were
averaging the same 7+ knots through the water, but the GPS showed the
speed over the bottom was lower.  Pilot charts suggest that, if
anything, we should have about .4 knot on our starboard quarter
pushing us along.  At any rate, the contrary current seems to have
disappeared and we are back to 7+ knots.  Go figure!

Weather and progress to Bermuda seem to dominate our thoughts out
here where the closest "land"--the bottom-- is 3.4 miles away, which
18,000 feet down.  Bob, we're grateful for your daily reports and
they jibe nicely with the reality we're experiencing, though the
reality is a little lighter than the forecast--much better than the
other way around.  We note that you are continuing to call for wind
and seas almost entirely aft of the beam, which makes for a
comfortable ride aboard Bluewater.

Since others on this e-mail are not getting Bob's reports directly,
here's what he calls for for the next couple of days:

  --Thu/18: SE-S 14-20kt gusty/25kt during the morning. Slow 

veering SSE-SSW 14-20kts, 25kts nearing the front thru late
Thu/night. ESE-SE 5-8ft, Increasing clouds, chance of
showers/thunderstorms nearing the front late Thur.

  --Fri/19: Mostly cloudy, chance of showers/thunderstorms passing 

the front through midday into the early afternoon. Winds SSE-SSW
15-21kt, gusty 25kt through midday, Becoming S-Var 10-18kt, gusty
20kt (winds of 25kt+ in/near moderate thunderstorms are still
possible/expected along the front) during the pm/hrs. Winds may
become more ENE-NE near/north of the front Fri/night-overnight with
more mixed sea/swell pattern; ESE-SE and WNW 5-7ft.

There's a question sometimes debated by offshore passagemakers: What
do you do about checking the oil?  My rule is to never shut down a
well running main engine at sea just to check oil.  As far as I am
concerned, the downside of interrupting the heartbeat of a running
engine at sea and not being able to re-start it is far outweighs the
upside of making sure the oil is right up to the top mark on the
dipstick.  If the engine loses enough oil to pose a danger to itself,
the oil pressure will drop, the alarm will sound, and THEN we'll shut
down.  In nearly 800 hours of engine time, our Lugger main engine has
never consumed as much as a quart of oil so I am comfortable with the
risk of not checking oil for days at a time.  Bruce Kessler says the
better choice is to have a Murphy Gauge which shows the oil level at
all times, but my own take is that a Murphy Gauge adds plumbing and
complexity, with the risk that entails.

Perhaps we're too decadent aboard this power boat, but we're still in
the tropics and are running with air conditioning 24/7 because it
makes for a  comfortable, happy crew--after all, this is supposed to
be a pleasure boat!  We're using the 12 kW genset to keep things cool
in the daytime, and transition to the 6 kW which can carry the
reduced electrical load overnight.  At a cost of 12 to 20 gallons of
fuel per day, this is a terrific investment in crew comfort.  It
reminds me that last time Dean was aboard we were fighting an
overheated engine room, and-thankfully-that problem is in our past;
the big 24-volt fan added to the engine room moves about 1850 cubic
feet per minute of cool outside air in to displace the hot air.  The
engine room is now running about 125 degrees, MUCH better than then
140 to 155 we had before.

Jim Fuller, owner and skipper of Summer Skis, telephoned early this
morning to report that he hopes to depart Florida today, which should
put them in Bermuda a day or two after us.  He was still waiting for
a final weather clearance from Chris Parker, his weather router.  We
look forward to seeing you in Bermuda, Jim!
