Dana Point, CA to Honolulu, HI
Jim Leishman - Voyage Director and Captain of Dana Point to
Honolulu leg
Tuesday - November 27, 2001
First
part of leg#1 completed within 24 hours of anticipated schedule.
Special
thanks to Georgs Kolesnikovs for his participation on our
first leg. Georgs enthusiastically volunteered for the Dana
Point to Honolulu leg covering all his own transportation
costs and proved to be an exceptional asset to the trip both
in his watch standing duties, his galley expertise and his
great coverage of the voyage details. Docking a day late in
Honolulu we couldn't even buy Georgs dinner the night of arrival
as his check in time for a 10:00 pm flight was less than two
hours after we hit the Hawaii Yacht Club dock. Georgs - we
hope you can come back and join us for another leg.
Monday - yesterday - back to the office - back to the real
world - Yikes!
Dave
Harlow, Ray Danet and Tom Selman have been at sea since Thursday
(Thanksgiving day) at about 1:00 pm Hawaii time. Before I
dug into the 20 days of chaos on my desk - I check the weather
and give the boat a call. The damn westerly winds are back!
They're about 500 miles south of the Hawaiian Islands and
a small low is moving north west across their path. I can
see the low is small and generating adverse winds of only
about 20 knots but early in their trip - it makes for uncomfortable
going. I assure them that the winds will clock around by today
(Tuesday) and by tomorrow the easterly should fill in and
with a little luck - it will take them all the way in to the
Marshall Islands (I've been promising Easterly winds since
November 3rd and can feel my ears burning from 3,000 miles
as Dave and the crew curse me). As I check the weather again
this morning (Tuesday) I can see that the low is dissipating
and moving to the northwest as predicted.
Essentially
the voyage from Dana Point to Hawaii was routine and uneventful
(as a good cruise should be). We arrived in Honolulu - covering
a total of 2,345 miles - averaging 6.04 knots in a total 388.19
hours (tach time) - slightly over 16 days. We departed Dana
Point on November 3rd at 4:00 pm (PST) and arrived in Honolulu
on November 19th at 5:30 pm (HST). The total fuel burn - including
about 20 hours of generator time - was 860 gallons.
The
only mechanical problem we had was the loss of our secondary
alternator, which is used to charge the main engine starting
battery. We noted this problem about the 14th day, and simply
flipped a parallel switch so the larger main alternator could
be used to keep the starting battery up. The belt and alternator
were changed out in Honolulu (we had spares aboard). Additionally
- we noted a slight bit of moisture in a coaxial connection
for the Iridium telephone that adversely affected the phone's
performance - drying out the connector and adding a dab of
silicone is all that was required. Upon arrival in Hawaii
we simply cleaned the boat, changed the oil and filter on
the main engine, fueled up and re provisioned. During the
trip we noted some variation in the engine speed and changed
out the engine mounted fuel filter. We never switched or changed
our primary filter (2 micron RACOR) nor did we ever change
it in Hawaii - it was clean and showed no vacuum due to the
cleansing effect of the fuel supply reservoir.
Probably
the most interesting part of the trip from a technical standpoint
was how contrary the winds were and how it affected the vessels
speed and fuel burn. The leg from Dana Point (Southern California)
to Honolulu was just under 2,300 miles and a bit more with
our diversion south of the great circle route, in search of
favorable winds. During our sea trials of a fully loaded vessel
we found that we could run at 1400 rpm - averaging 6.3 knots
and consuming about 1.9 gallons of fuel per hour. This is
a boat weighing over 50,000 lbs with a bow thruster, wing
engine and 12 square feet of stabilizing fins. Running the
math forward - we concluded that with 920 gallons of usable
fuel - we would have a run dry all out range of 3,050 miles
assuming the weight of the vessel would not change. Using
the performance of the vessel at it highest possible weight
will give a reserve in itself because the weight reduction
alone in fuel will insure better performance at the end of
the voyage - adding to the true range of the vessel. Taking
the great circle route to Honolulu - we should be able to
arrive with reserve fuel of 233 gallons or an excess of 25%.
As
it turned out with NORDHAVN - we had sea state conditions
which I would consider normal for the voyage - however the
wind that generated them was not the planned Easterly - but
a South Westerly wind - which hampered our progress almost
the whole trip. The low-pressure systems that develop up in
the Gulf of Alaska and arch down bringing winter storms to
the California coast were developing a few weeks early then
what is typical.
The
relatively rough conditions encountered offshore will slow
down any vessel significantly (6% to 10%) from its calm water
performance however the wind that creates the rougher sea
- if consistent will generate a surface current. In the case
of the California to Hawaii passage that surface current is
typically about ½ knot in a westerly direction, being
generated by 15 knot easterly winds and this normally would
have offset or cancelled the anticipated rough water speed
reduction. We got slowed down, loosing speed to the bumpy
water, plus we got hit with a surface current - going the
wrong way - a result of sustained Southwesterly winds.
The
net result is that we burned the anticipated amount of fuel
per day (48 gallons) - however our speed was reduced by over
½ knot. As we approached the Hawaiian Islands with
a good weather forecast and great confidence in our fuel consumption
and the amount remaining - we increased speed and made up
most of our lost time - arriving only about 15 hours later
than planned but with much of our reserve fuel consumed -
clearly illustrating the need for an adequate reserve.
Despite
the westerly winds we did enjoy some lovely tropical weather,
great food (including lots of fresh Dorado) and the comradely
and relaxation that a long ocean passage can generate. Our
40 foot NORDHAVN proved to be a wonderful passage maker and
the success of the first and longest voyage of the circumnavigation
confirmed the vessels ability to safely and comfortably complete
the challenging legs that lie ahead.
The
leg now being undertaken - Hawaii to Majuro - is also a long
leg (just under 2,000 miles) and has been planned at 6 knots.
This leg should be relatively free of the disturbances encountered
farther to the north and east and the surface currents have
a stronger westerly flow. Despite the localized low pressure
system now being encountered we hope for an average speed
in the mid to high six knot range. Once Majuro is reached
- there are a series of shorter legs in the 1,000 mile range
- and we hope to see speeds here in the mid to low sevens.
