Week 13
Nothing much this week...been too busy trying to get the boat organised for...next week! The setback with the longer winter and extra ice has meant that I am 3 weeks behind schedule.
And it looks like we'll be needing beanies on board, at least for the men behaving baldly.
Ben is visiting this week; a touch of "home" before he heads off to Madrid for 2 weeks modelling work and then 70 days under contract in Shanghai.

Boat Works
“Believe me, my young friend, there is nothing - absolutely nothing - half so much worth doing as simply messing about in boats.”― Kenneth Grahame, The Wind in the Willows
The case of the Leaking Diesel Tank
And of course the tanks were there first, so impossible to get to all the supports, or even see them for that matter!
Scraped off all the insulation, just to be able to see...
Finally found the hole - in the middle of the underside of the tank.
The tank has bulged slightly so that the lowest point is where the water collects - and where it has rusted through from the inside, after 40 years!
We tried this fix - a metal plate with epoxy and held in position with a block of wood. (photo below)
Now, here's the thing about diesel fuel. Since they have been using bio-diesel, there is more chance of algae forming in the tank, especially over long idle periods - ie the almost 6 months of "winter" here! There is a fuel additive to prevent this OR, indeed a "new" fuel...
GTL is very clean according to Salland, it contains no sulfur so no unpleasant combustion air arises and because of the cleaner combustion remain valves, injectors and cylinders clean inside. This will result in less wear and tear on the engine, resulting in a longer service life.
GTL stands for Gas To Liquid. The product is made from natural gas that has been liquefied. This process is not new, it has already been discovered and applied since 1920. At that time it was developed through the scarcity of petroleum products. Synthetic crude oil is produced from natural gas, which is then separated into a few products. A derivative of this is a gas oil fraction which is comparable to conventional diesel. Because there are large gas stocks on earth, it is expected that products such as GTL have a future.
GTL diesel is virtually odorless, so you no longer have the stench of traditional diesel on board. GTL can be used in any engine, your tank does not have to be empty when refueling, it can easily be mixed with traditional diesel.
Metal plate fixed with epoxy...
However, the new fuel reacts with the epoxy, so that it doesn't set! (apparently it also reacts badly with rubber parts in old motors - ours is OK. Even so, I think we'll go off the new diesel and just use a can of additive.
Of course this is only a temporary fix. The most likely solution will be to cut out the side of the tank to make room for a new plastic tank. This will be large enough to replace both the existing tanks - then arises the question of "ballast", but that problem is for another day...
Difficult to see, but we have now gone for a "physical" stopper - a sheet of rubber (non-reactive) held in position with a block of wood. When it is dry, this will be coated with epoxy simply so that it is more likely to stay in position.

Nav lights all working... (all these fittings are also 40 years old - so I'm always pleased when they work!).
A new "tooter" to warn off the big ships...
A ventilation hole for the new "dry" toilet...
The porthole in the aft cabin has been leaking - and more water than I had anticipated had gathered under the bed base... now dry and a new rubber in the porthole - more for fresh air than light.
From the newspaper...
More than 1.5 million elvers were released into Frisian waters during the week. The eels originally came from the Sargasso Sea. They can no longer find their own way into the fresh water - hence the "helping hand". It is expected that only 5 to 10% will survive.
Climate Change
I heard a disturbing report during the week that 45% of Americans don't believe in Climate Change. Not sure how they arrived at that figure... here in the Netherlands the "belief" is in full swing. Cars, gas heating, alternative sources of energy, environmental concerns... The latest is that all "traditional" heating systems have to be replaced (when needed) with systems not using gas - by 2021. We have 7 of those systems!!! Fortunately, I'm not the only one concerned about the cost... the newspaper reported briefly that the Coalition Govt. is "divided" over concerns about the costs to consumers...
I think it is good to have "values" other than the pursuit of money, money, money - but crikey!
