Christmas lunch in Fiji

Posted on Wednesday December 25th, 2013 by dafdaf

I live a pretty chaotic life – always have. And there are not many traditions that I stick to. But spending christmas with my family and – especially – eating the most amazing meal of the year: the christmas turkey of my grandmother was one of them.

And although I’m sad that I can’t see my family this year, we found a good replacement for the lunch itself. Two days ago we were invited to spend the 25th with a family in a village near Savusavu. Spending christmas in tranquility is a luxury most people of the western countries don’t have. And spending it out in the middle of nothing in a village with 123 inhabitants is a blessing.

The food got prepared the traditional way with heated stones, covered with palm and taro leaves. In the lovo were prepared: wahoo, chicken, pig, taro, breadfruit, little packages of fish with onions wrapped in taro leaves and steamed in coconut milk, etc… The feast was awesome ! After that we hopped in the nearby river for refreshment and  the men (yes: only the men) sat together to drink cava and sing traditional songs. The kids spent all afternoon in the water, jumping from trees or paddling along with a little bamboo raft. This christmas will be one of my favourite memories of that journey so far !

Tropical Cyclogenesis

Posted on Monday December 23rd, 2013 by dafdaf

With all the work on the engine I completely forgot one of my favourite blog topics: the weather !

The marine weather report here in Fiji is quite funny: although there was not much wind during these last weeks, we were continuously warned of foul weather and heavy rain. When we had 15-20 knots, the marine weather warned of ‘rough seas’ sometimes even mentioned ‘very rough’ seas – even when the wind in this area wouldn’t even exceed 25 knots. I guess, the boys and girls from Fiji’s weather bureau don’t get out to sea much – otherwise they would know that it takes waves of four to six meters with breakers to qualify for a ‘very rough’ sea. Don’t get me wrong: I really appreciate them sending meaningful warnings out to the people cruising the oceans but if you shout ‘Fire ! Fire !’ all the time – no fire brigade will show up when it really burns. I know this analogy sucks but I guess you get my point.

A related story might illustrate it further: When we were cruising the Canary Islands in 2011 some overeager employee of the local authorities sent two DSC-alerts in front of *every* marine weather bulletin. This means that six times a day the whole crew is startled by the intense alarm of their VHF radio just because they send weather info. This resulted in most of the yachts turning off their VHF ! Fortunately we could revert to our handheld radio which doesn’t support DSC. Hopefully this dangerous and silly practise since has ceased.

Global Tropics Hazard OutlookTropical wave - infraredTwo lows form on 20131225Outlook for friday - not so good.

Well but now back towards the actual cause of today’s posting. One of the most important tasks of the local weather bureau is to alert the population in case of a cyclone. And right now there is no such warning. Although in my opinion, the situation is quite critical. Wikipedia lists six requirements for the development of a tropical cyclone:

  1. Warm ocean surface of at least 26.5°C. – check
  2. Atmospheric instability (tropical wave north Fiji towards Tonga) – check
  3. High humidity in the lower atmospheric levels. – check
  4. sufficient Coriolis force (always given near the equator) – check
  5. Preexisting low level focus or disturbance (two lows north of Fiji) – check
  6. Little vertical wind shear (hard to tell but likely)

Two additional factors are left out: El Nino, which has influence on hurricane activity – but this year is no El Nino event. And the Madden-Julian-Oscillation which seems to have massive influence on the frequency of tropical storms. In a scientific study done in 2009, the area of Fiji-Samoa-Tonga was investigated and the study came to the conclusion that in case of an active MJO there are five times (!!) more cyclones forming than during the inactive phase. The MJO develops in a 30 to 60 day rhythm in the indian ocean and then travels east. According to current observation, the MJO will reach our area during the next days. Although it’s not extremely active, it still enhances my alertness.

Let’s hope, Fiji’s meteorologists know what they do. I’d be happy if I’m proven wrong.

Getting out of the Nakama Creek

Posted on Saturday December 21st, 2013 by dafdaf

Every now and then we excape the anchorage and get some fresh air out at the reef. Only four miles away there is the Cousteau Resort at the very end of the strip of land that encloses the Savusavu bay in the south. Out there, closer to the open sea the water is a lot nicer (although still far from clear), there is wind and the insects are less annoying.

A little trip like that brightens the mood and once we hop into the water and have a look around in this big aquarium, the day is safed. The difference to the more eastern parts of the Pacific are big and the diveristy of fish and coral still amazes me. Especially as we’re not in a proper dive- or snorkelspot. For that one shoud go out to the smaller islands or visit the neighbouring Namena, only 25 miles from here. The diving there must be one of the best in the pacific and we will check it out sometime.

As you can see in one image, the Suvarov already got decorated and ready for Christmas. The kids had a lot of fun engarlanding the whole saloon, hanging stars, balls and little angels. Viola spent hours cutting colorful stars out of paper and decorating the cockpit dodger.  Otherewise there is not much reminding us of the year’s top consumption fesast. There are no huge masses running around on the streets, trying to get some last-minute gadgets, no decoration on houses or in shops and best of all: No stupid christmas songs !

To that effect, I want to wish all our readers and friends a verry happy christmas and a beautiful 2014 !

At the Maroroya Falls

Posted on Thursday December 19th, 2013 by dafdaf

With all the heat in the engine room (and outside) we try everything to cool ourselves. A few days ago we set out on a little journey together with the crew of the SY Time Lord. Our destination: The Maroroya falls near the Nakawaga village. We get there by car (takes about 30′) and stop a little before the village where the path starts. The walk through the jungle is only about half an hour and very nice. Beautiful flowers and trees all around and soon the kids can hear the waterfall announcing itself through the thick, lush green.

The kids have a lot of fun walking through the forest and the hightlight-  the bath in the cool, fresh water will not end. One can actually swim through the two little pools and go right under the fall itself. Where the water is quiet, in the little ponds the kids collect prawns – which they set free again after a while. (Too small to eat. ;-)

After a extensive picknick we start walking back. When we reach the road, we call for a cab which will take about 40 minutes to get here. As the sun burns down on us and we see a river nearby, we climb down and follow the creek until we reach deeper water. Another nice, cool bath, yay !

It was a really nice little trip  – we should do that more often. Well – now that my engine project is on hold, I guess we’ll get out of the dreaded anchorage more often…

Getting hot

Posted on Wednesday December 18th, 2013 by dafdaf

News on the engine front: After flushing the engine approx. ten times with 5% H2SO4, the cylinder head now looks like new. Also the sacrificial anodes are 50% gone. Heh. But the problem remains: when running the engine in idle mode the temperature is fine; when the engine has to move the boat, it will overheat after only three minutes. Ten minutes later we can already see a little steam coming from the exhaust.

Before......and after.The water pumpnew gaskets made from scratch

Yesterday I again checked the impeller and replaced it (just in case) but that didn’t do anything. I also cleaned the seawater inlet and filters which means EVERY part of the cooling system now was checked.

My last hope is the following: I don’t think there’s enough water coming out of the exhaust. Maybe the whole system is flawed from the beginning and we just need a water pump with a higher throughput ? The manual says, it should pump 800l/h at 1400rpm which I will measure later. Any other ideas ? Anyone ?!?

Patience with the patient !

Posted on Monday December 2nd, 2013 by dafdaf

There’s not too much to do here in Savusavu. We knew that already before we came here and that’s ok. Gui is organizing the trip to Argentina. We all will travel there and we need plane tickets and visas for Australia (a pain in the a.. !!) In Argentina Gui will work on the upcoming collections for Coquito and the Kids will have fun with the grandparents.

Frueh morgens in SavusavuSpiegelglattes WasserUnsere mini-Nachbarinsel, heute mal doppeltBruno und der iPod. Unzertrennlich.

So what’s the captain doing ? Fixing things – of course ! I can’t sit still for too long and there’s enough work on the Suvarov. Our engine still tends to overheat so again I took apart the whole cooling system. All the tipps of the boat neighbors and of Leon (the local machanic-guru) are implemented. The whole system is checked from inlet, impeller, all hoses, mixing elbow, water collector to exhaust. But the problem is IN the engine which is no surprise since the above mentioned parts were checked before we left Polynesia.

During that check I was quite confused that I didn’t find a thermostat. Now – with the proper manual I could verify: It’s indeed missing ! Luckily somewhere with the boat tools I found a box containing four used thermostats who after checking were all verified to work correctly. They just needed some cleaning.

The next surprise was the air filter – I wanted to clean it but – there is no filter in there ! Well. That safes me a little work. ;-) Next step: replacing the sacrificial anodes. That’s convenient because while doing that I can have a look inside the cylinder head and see wherther there’s any calcium builup. Next surprise: instead of a gasket someone used household silicone ! – On the front of the cylinder head !! The backward plate had no gasket at all. :-) Luckily we have gasket paper on bord and Gui made nice new ones for me.

So sollte das eigentlich aussehenDer Mischer - in dem Auspuffgas und Kuehlwasser zusammenkommenEntrostet und neu lackiertUnser Patient bei der Chemotherapie - mit ausstroemendem CO2

Inside the cylinder head it looked a lot like a flowstone cave. Lots of stalagtites and stalagmites – and even some crystals ! What a beauty !! Well – and why the cooling of the engine isn’t really working well is clear now. After consulting the almighty internet I find out that it’s best to use 10-15% acetic acid to remove that calcium buildup. Unfortunately the only related liquid available in Savusavu is white vinegar. So I decide to take a little risk and use 5% sulfuric acid to remove the crud.  I fill the (warm) engine with four liters of acid and let it sit until it stops hissing and bubbling. From the connection on the top of the engine we can see the CO2 escape. A nice chemical experiment for our schoolkids. The acid cleaning will continue for the next days. We’ll see whether it works…

While I was at it I also changed the oil, de-rusted and painted some parts, replaced hose clamps and hoses, etc. A nice little service for our engine. As you might be curious it’s a Yanmar 3QM30H with saltwater cooling. And as I had to search forever to find it, I safe others the work and put a link to the service manual !
