Life on Fiji
Part 8,
From 02-08-2008 to 03-02-2008
“In the
flames of love even the hardest iron will melt.”
Mohandas Karamcsand Gandhi (lawyer, politician).
He was a major political and spiritual leader of India and played a major role in the Indian independence movement. In sanscret
Mahatma means “ great soul”. According to his doctrin the force of truth is
always victorious therefore one has to use passive resistance to achive the set
goals.
02-08-2008 (day 502)
Shopping in Lautoka. I bought 5 mini DVDs for 45 FD. These didks
are for my camera and will be enough for the next 6 months. For lunch and
supper I also bought 2 rotis and a few roasted kasavas (2.7
FD). I talked to Bruce because I have to
change two standing ropes and he is the riggmaster. Tomorrow, in the Marina, I
will give him the old ones to use them as samples.
I visited Ruben and
gave him a picture as a souvenir. The picture showed my boat and myself. I
spent the afternoon there. In the evening I took a bus back to the Marina. I
was typing late into the night.
Religious division on Fiji:
Fijien:

”Hate the sin, love the sinner” Mohandas
Karamcsand Gandhi
When Rabuka was
prime minister the people from India had their basic human rights suppressed.
In 1990 there were 47% fijians and 50% Hindus, but since 1987 the people from
India were continously leaving the contry. There were years when 9000 of them
left and went to the US or Australia or New Zealand. Now the Fijians are the
majority. At the moment those people are second rate citizenzens in Fiji.
Lp gas fillup 4.7 FD. The secon gas
bottle needs repair, it leaks. Then a short time on the Internet and writing on
board.
02-10-2008 (day 504)
I continually compare the life here and in Hungary. Here the
people sleep 5-6 hours, but in Hungary it is more like 8-9 hours. Secondly
there is not that much stress here; the work is not as hectic, but of course
the pay is less too. In Hungary a workday is 8-9 hours but that includes stress
and during the rush hour in Budapest add an other 1-2 hours travelling time...
This is the third
world, backward and poor. There is little money here, but maybe it’s enough.
In the morning I talked to Bruce. For 70 FD he’ll change two
of the holdown ropes. Earlier I was working on those, but they are not ok. After this I
stopped by at Ruben’s for lunch, (fish lovo, chicken with coconut sauce). In
the afternoon I was with Hans and we tried to repair his radio, but I still
could not find the problem. I had supper with him. It was a vegetarian supper.
Evening movies: An Inconvinient truth (Global Warming) – Al
Gore; Bowling for Columbine. (Finally I can see good movies – I recommend those
for viewing. I have seen these before, but it was good to see those again).
02-11-2008 (day 505)
New ideas: I want a
boat that weighs less ( Carina could go faster in
weaker wind).
-
Carry less food. Store it for 60 days max. ( so far I carried food stuff for 120-140 days)-100 kg.
-
less water ( 100
l. bottled and 100 l in bigger containers): -100 l
-
I will try to
leave behind a few unimportant things, but instead add 1 or 2 different tools.
And in the future I still will not have a dinghy or serfboard
Early in the morning Marty with his microbus took me and the
engine (Bobby helped me to take it out). Engine work is a slow process, people
do not hurry here, so today we could not even start it. Tomorrow we’ll
continue. I went to the APCO factory to buy paint, but they will not sell any
this season, so I will have to buy it in a paint store in the city. It will
cost more. Lunch in the city: Fish, potato with roasted kasava and 1 roti
(3FD). I stuffed myself so supper will not be necessary. MP3 player 60 FD,
Charging the telephone 5 FD. I took a bus back to the Marina.
Satya Sai Baba’s web
pages (It would be difficult to describe those in a few words, But I do not
want to leave them out):
http://www.srisathyasai.org.in/
http://www.shirdi-sai-baba.com/
02-12-2008 (day 506)
Early morning I took the bus to the city. I took a battery to the
motor mechanic and
started the engine. The charge for the checkup was 25 FD, this included the reinstallation of the stand, oil and a
compression check. The problem is that after 10 minutes both spark plugs get to
be full of oil. This is not new.
There are imperfections here (piston ring set, upper casing gasket, oil seal
(bottom) .
Here The Yamaha agent is Asco Motors. I talked with Rajesh and I sent them the
Yamaha 677-8 B 8 HP catalog. This way he will have the exact type number. After
all this I visited a few paint stores to get prices.
2 l primer APCO (199 sealer)
2 l thinner A[co 603
2 l polyurethane finish APCO (343 gloss)
1 l thinner APCO 604
The best price is at Sahay Brothers (170
FD).
The other
possibility is to use resene paint (Uracril 403, Duprex primer). This one is a
little priceier and according to Hans the quality is not there. Tomorrow I will
continue to talk to a few more experts.
Lunch and
supper is cooked chicken with kasava (3.8FD); this is
like the national food around here, One can get it in just about every
restaurant. This is the first time that I tried it.
I met Nani
again. The first time we met was in the Nandi hospital. This time our chance
meeting happened in the Yacht Club where he was drinking beer with his 50 year
old English wife. Nani is a 32 year old fijian-indian, who is supported by his
rich wife. He helped me to put out a fishtrap in front of the reef using his
own motor boat. After that we had a few beers on board Carina.
This evening I wached the English version of
Fahrenheit 9/11. Hans lent it to me.
02-13-2008(day 507)
The plate that
holds the mast is getting rusty so I sand papered it then painted it with
rustproof paint. Nowadays I use several layers. I met Ben’s brother Paul. I met
Ben while I was in Tonga in November. Tomorrow he’ll come and take a look at
Carina. In the afternoon I visited Asco Motors in town.
H. Gasket: 30 FD (
Piston Ring: 20 FD (
Upper Case Gasket: 31 FD (
Seal: 22 FD (from
Carburetor Gasket: 12 FD (from
Valve Gasket: 18 FD (from
All this means that the engine will be ready by
the middle of March the soonest.
I also talked
with David, the motor mechanic, maybe he can give me a break on prices. It is
funny, but I meet more and more people I know. However I’m here for 3 months
now and maybe that’s the reason. I stopped by Zaki for a short visit.
I got aquaited with Klod who is 52 years old
but looks only 30. Most of the sailors are looking younger than their actual age.
Klod is from South Africa and him and his family are sailing the seas in their
katamaran for the last 8 years.They would like to
settle down here. „To be happy every day”. This gives energy and open up
oportunities.” I think happiness slows you down and the impetus to move forward
will be missing. For me the most important thing is to have energy.
”According to crime statistics, in South Africa they murder 350 people
daily and 1000 suffer attacks and become victims of robbery. (This is the reason he left his country.)
In the evening
I watched Patch Adams with Robin Williams. This was better than the usual
American films.
02-14-2008 (day 508)
I talked with Willi
(he is the local shipyard’s boss) to give me some advice on paints. I wanted
quality so I chose the Apco brand and not the resene. These are the only two
types available here (primer and topcoat). I met Paul again. Later, in the
city, I ordered the parts from Japan (Yamaha) and talked with David about this
also.
Lunch and supper: 2
rotis and roasted kasava (2.6 FD).
I did some diving in the afternoon and inspected my fish traps.
They were empty; I guess they don’t like crackers. Maybe I will get some
chicken pieces from the kitchen. The fish love chicken pieces. The diving lasts
1.5 hours and it is an unbelievable adventure (the corals and the fish are
marvelous), but tiring.
In the evening I read, from the laptop, Kurt Vonnegut’s book:
Breakfast of Champions.
There is hardly
any literature in Hungarian about the so called freak waves so here is a short
introduction.
There
are videos on the Internet about freak waves, which are enormous killing waves that come from
nowhere and sink ships. Basically they are a wall of water that destroys
everyything in its path.
http://openflv.com/fullscreen?v=NjY3NzEzMQ==&p=0
http://openflv.com/watch?v=NjY3NzEzMQ==&p=0]Freak%20Wave
Rogue waves, also known as freak waves, monster waves
or extreme waves, are relatively large and spontaneous ocean surface waves
that are a threat even to large ships and ocean liners. In oceanography, they are more precisely defined as
waves whose height is more than twice the significant wave
height (SWH), which is itself defined as the mean of the largest
third of waves in a wave record. It is common for mid-ocean storm waves to
reach 7 meters (23 ft) in height, and in extreme conditions such
waves can reach heights of 15 meters (49 ft). However, for centuries
maritime folklore told of the existence of vastly more
massive waves -veritable monsters up to 30 meters (98 ft) in height
(approximately the height of a 10-story building)- that could appear without
warning in mid-ocean, against the prevailing current and wave direction, and
often in perfectly clear weather. Such waves were said to consist of an almost
vertical wall of water preceded by a trough so deep
that it was referred to as a "hole in the sea"; a ship encountering a
wave of such magnitude would be unlikely to survive the tremendous pressures of
up to 980 kPa
(142 psi) exerted by the weight of the breaking
water, and would almost certainly be sunk in a matter of seconds. Many years of
research have confirmed that waves of up to 30 meters (98 ft) in
height are much more common than mathematical probability theory
would predict using a Rayleigh distribution of wave heights. In addition,
pressure readings from buoys moored in the Gulf of Mexico at the time of Hurricane Katrina also indicate the presence of
such large waves at the time of the storm. In fact, they seem to occur in all
of the world's oceans many times every year. This has caused a re-examination
of the reason for their existence, as well as reconsideration of the
implications for ocean-going ship design.
Freak Wave:
The world's oceans claim on average one ship a week, often in mysterious
circumstances. With little evidence to go on, investigators usually point at
human error or poor maintenance but an alarming series of disappearances and
near sinkings, including world-class vessels with
unblemished track records, has prompted the search for a more sinister cause
and renewed belief in a maritime myth: the wall of water. Waves
the height of an office block. Waves twice as large as any that ships
are designed to ride over. These are not tsunamis or tidal waves, but huge
breaking walls of water that come out of the blue. Suspicions these were fact
not fiction were roused in 1978, by the cargo ship München.
She was a state-of-the-art cargo ship. The December storms predicted when she
set out to cross the
There are three categories of freak waves: "Walls
of water" traveling up to 10 km (6.2 mi) through the ocean;
"Three Sisters", groups of three waves; single, giant storm waves,
building up to fourfold the storm's waves height and collapsing after some
seconds.
02-15-2008 (day 509)
Every day I hear the sea’s rumbling, but
I’m not on water. The shore is less than 100 meters from me. I miss sailing.
In the morning hours I was talking with
Hans. What about? Well just about everything, but the main topic was sailing.
Later I went to Ruben’s to eat lunch. It was late in the afternoon when I got
back to the boat.
I started to dig a deep ditch under the rudder. I have to remove
the rudder at least half way in order to be able to repair the skeg.
Basic ocean sailing techniques (I am using those myself).
One cannot read about these in the Hungarian sailing literature so
here is a short introduction:
hove-to, heaving-to, lying-to, lay-to
definition:
To stop moving esp. to slow down or stop
due to heavy weather. Trimming sails and rudder to reduce the sailboat's movement to near zero. Specifically,
to back the jib, sheet in the mainsail, and tie off the rudder to windward (tiller to leeward) keeping the vessel's head to windward
to meet the waves and its movement limited to crabbing across the wind. One of the many tricks sailors use when the weather gets too wild
for comfort to simply take a break from the helm. As the wind and waves get higher, the crew might
choose to heave-to as a way to slow the boat down and ease the motion through
the waves. By slowing or stopping the boat, the crew can gain a chance to rest,
to make necessary repairs or adjustments to the rig, or even simply to make
lunch. There are several other occasions when a boat's crew might wish to
heave-to. In a crew overboard
situation, heaving-to stops the boat during the retrieval. When approaching
navigational hazards at night or in poor visibility, slowing or stopping until
visibility improves can be the safest course of action. And, on a sunny day sail the crew can heave-to
so all hands may enjoy a picnic at sea. The goals of heaving-to are to have the
bow pointing into the oncoming waves as much as
possible, to prevent the boat from moving backward or making too much leeway, and to reduce the motion of a boat so
the crew can rest. (The ultimate goal, of course, is to keep the boat afloat
and undamaged!) The most common method of heaving-to is to come about from port tack without releasing the jib
sheet. With the main sheeted in tight, immediately put the
rudder down - being careful in the process not to come about again. At this
point the boat should be in a stable condition; the main will fill,
overpowering the jib, which is holding the bow down. As the boat begins to move
forward, the rudder will turn the bow to windward, luffing the main. As the boat slows, the
jib will push the bow down again and the pattern will repeat. On a reach, a boat can be temporarily slowed or
stopped by undersheeting the sails and setting the
rudder somewhat to leeward of the course. As the boat accelerates, it will turn
into the wind, luffing the sails. The luffing sails will slow the boat and cause it to fall off
until they fill again, and the pattern will repeat.

Late in the morning I connected to the Internet in a coffee shop.
Ana gave me lunch free of charge and that of course was roti.
In the afternoon I did some diving and took a look at the fish trap – maybe
something is caught in it. But there was nothing there. So far they did not put
any bait into it. Then I watched a few old Sherlock Holmes films.
I spent the
evening with Samu and his young aunt and went out to have a good time in a
night club called Cave. When the night club closed we continued the party
outside in a meadow. This went on till dawn. I slept at Samu’s place.
There is a new
sailing trend afoot, they call it ocean sailing with mini sailboats:

Early morning
I was on the Internet for two hours. Yesterday evening I brought home a
few chicken bones (and small pieces) from the kitchen of the Yacht Club. These
were used for my fish trap for baits. I put them out during my morning swimming
and diving exercise. I hope the fish
like them. The minimum swimming time is 1.5 hours.
I took a bus ride to the city to buy paint to
do the outside of the boat. It cost 170 FD. I took the computer cable for
repair also. This I could not do by myself.
Lunch and
supper: roti and roasted dalo/kasava
and a number of different roasted vegetables.
Unfortunately
so far I could not find any acetone with suitable pricing.
During the
night I was on the Internet for a few hours.
The movie for

not ready yet, - maybe tomorrow.
Lunch:
roasted chicken and baked potato (3.5 FD).

In the
morning I spent an hour on the net in the coffee shop (the WLAN is free of
charge in the marina. Later I went to swim and dive and hunt for fish. This is
my sport activity. I do this every second day for about 1.5 hours. I swim out
to check my fish trap then swim back to the shore. Today it was high tide and
found more then the usual amount of fish. I even found fish in my fish trap (it
was small L).
Again the
usual dish washing (I hate it), and cleaning (I just not like it), after that
Jim the captain of a motorboat took me in the city with the company microbus.
Finally I could pick up my paint and also the repaired cable for the computer
(12-19V, a diode burnt out. Cost: 20FD).
Lunch:
Chinese (3.5FD). After 3 months I had enough of roti.
Slowly I get acquainted with every eating-house in the city.

During the morning hours I
watched Sherlock Holms videos and the Blue Planet (seasonal sea, coral sea).
It’s raining the whole day and I

Paul came over and we went to a coffee house and drank coffee and played cards
till 5 in the afternoon.
For
lunch I finished what was left from yesterday’s supper, but I should not have.
I came down with diarrhea and was throwing up. So I stay home tonight.

I have not got a frigerator this thing is always fresh. During the morning
hours I read and connect to the Internet for about a half hour. Then no more
Internet.
Somebody suggested that I should
meditate as much as possible on the beach.
Harmony
is always welcome. If there is no rain I go down to the shore and before
swimming or diving I try to meditate. It’s easy to say, but not easy to do.
The infected scar on my face is

In the
afternoon I made a trip to the city to buy some ointment for my back pain and
some for infection. I looked around for acetone and the cheapest that I found
cost 12.5 FD. This is highway robbery if you ask me! For supper I ate chinese. In the evening I went

piece on my web page about meditation before I started out on this journey.
Many people do not believe in it. If we want to live a full

want to write about him.

From
now on I count backward and getting ready for the next phase.
Unfortunately
two bags are missing, did not get here to the Marina and this I can hardly understand
I talked with the manager, but he gave me only promises.
I reorganized
the medicine cabinet in the morning hours. I have to buy a few tubes of
antibiotic cream.
The cockpit’s floor is starting
to rot; I have to start to repair it using synthetic resin.
Breakfast and lunch: plenty of
scrambled eggs with onion.
The iron
plate of the mast-holding bar was getting rusty so I sanded it and tomorrow
will paint it with rust proof paint.
In the
morning I walked over to Lion who gave me a sander and a 110 V generator. I
purchased gas for the generator at the fuel dock. I like Lion’s boat a lot.
It’s a huge salon that contains a large sofa. I think given a sofa like this
and I could spend my next 50 years on it.
In the
afternoon I spent an hour in the swimming pool with Lion and his son, then I
went back to continue sanding the boat. Unfortunately later the rain came -
again.
In the
evening played cards and drank a few beers in the club. (With Paul – I sailed

I was just thinking that how big an engine would be best for
Carina and later I got the answer from my father:
The engine must overcome drag. Tthe mass of the boat becomes important
during acceleration.
If the sea is calm (no wind,) then only the water’s drag is important. So:
-”A”: The underwater part of the boat’s (it’s the biggest in the traveling
direction) cross section (m²),
-”ro” density of the agent (kg/m³)-
-“v” speed of the boat
(m/s) – to be more precise its square v² and
-“c” drag coefficient (it
is without a unit of measure, it is only a proportional number)
To calculate: F = 1/2*c*ro*A*v²
Example:
Let "c" be 0,4 (It it’s a bell-shaped 0.45, in the case of a boat it is
smaller, but the eddy currents make it worse).
"ro" at sea water is about 1025 kg/m³,
Let make "A” 1 m², and
that depends on the boat, Carina is maybe about 0.4 m²,
(at
this time, because of the water displacement (draw), the boat mass counts.
Let “v” be 0.5144 m/s (this is 1 knot) then:
F = 54 N, and P = F*v = 27,9 W
= 0,038 HP, therefore:
P[HP]
= 0,038*v[kn]*v[kn]*A[m²],
At 4 knots this has to be
multiplied by 16, at 5 knots by 25 so we get about 0.6 or 0.95.
If the cross section is 2m²
then 1.2 HP is needed to reach 4 knots or 1.9 HP for 5 knots.
In this discussion there is
no thought given to know how much of the engine performance is for driving the
boat and how much is going to stir the water ( this depends from the engine
revolution, from the pulley etc.), I think this is a 0.5 multiplier, which
means that the previously calculated output has to be doubled.
Of course if there are
waves, those waves have great effect on performance. Even when the waves are
ordinary the necessary output can double. When the waves
become big then the shape can make a difference too and the whole calculation
process changes.
Stormy winds are important
too but basically everything remains the same. The air density is about 1.2
kg/m³, and the over the water longitudinal cross section in a bigger boat
without sails could be 4 m². If the wind is 20 knots then the force is 86 N
against the wind and at 40 knots the force on the boat’s hull could become 350
N.
During the morning hours I was patching up the cockpit’s bottom
and started to paint the outside of the boat.
In the early afternoon I was relaxing in the swimming pool with Klod.
Then it started to rain and that stopped all work.
There is a hidden meaning of Bob Marley’s song, Catch The Fire. Only a few people know about it. This is one
method to get closer to God. (See my short writing about the “rasta” movement.) These people believe in a special method
and they call it ganja lighting. They use the sun, around

The difference
between a yacht and my boat is like the difference
between an apartment/hotel and a tent (which sometimes leaks.) I always liked
to be in a tent. It gave me a feeling of freedom and I can relate a few funny storiesJ.
In the morning and the afternoon I did some sanding and painting
(primer). At some places the paint peeled off, mostly where the bottom shell and the top shell of the boat meets. This will
last about a week. I also keep repairing the bottom of the cockpit.
David’s wife gave me “kimcsi” for
supper. They are from
