Espar hydronic heater - heats the hot water tank.  So I can do dishes and have a shower.  It is most excellent.  Does a great job of heating the boat as well...

The heater units I'm using are from Heatercraft, they work well - 12v fans to move the air around, and one of them has 2x ducts on it so I have heat in the head.

The shower on my boat is better than the one at home.  I fitted a Mira minilite thermostatic mixing valve. The shower rose has a trigger to keep usage down.  A chamois leather is used to dry the head compartment afterwards.  Haven't used a marina ablution block in years.

@Whinging Pom I like your solution but I don't think I have room for it on my boat.

I think my one complaint is that it's a long run from the water heater to the head. It does waste a bit of water to get the cold water out of the lines. Then, the water saving shower process of rinse down/water off/suds up/water on/rinse down allows the water in the line to cool rapidly on those early spring and late fall days.

I wonder if some sort of insulating wrap on the hot water hose would be beneficial?

You could fit a valve to dump water back into the tank until it gets hot.

I think it's a pretty safe bet that insulating the hot water line would help. Even in this day and age, thermodynamics still applies.

Never go to sea without a chamois.  Just the job for drying your hands before working charts etc.  The great thing is they never run out of the ability to dry.  The other always take item is a roll of polythene rubble sacks.  Just the job for dealing with deck leaks, torn oilskins, keeping sleeping bags dry etc, etc.

Our head water is hot by the time it fills the tea kettle.

Yep, I put plumbing pipe foam covers over all the places I could reach.

To expand on that, all our drinking water goes into a Brita filter jug, then to the tea kettle. Makes a huge difference in the taste.

Still, drinking head water is a bit extreme. Don't you have faucets in the galley?

The only times my diesel wouldn't start was due to electrical problems.  So the vaccine would have been a hand starter.

My engine is reluctant to start in the cold. I dont think it's just the battery.

I'd like to install a filter on the line but I'm not running stuff through a Brita pitcher and then into whatever cooking receptacle.  My tank water already tastes fine to me. I clean them seasonally.

We fill our tanks whenever/wherever we can while cruising, so there is a bit of *variety* in taste, running it through a Brita smooths it out. A filter would be a nice option, but that cabinet is already full of stuff.

Time for an update on the marine 16 treatment

to recap....

I bought the boat in September,

It had stood for seven years with a full tank.... stainless steel  with no access hatch.

 

I knew I was in trouble

So I put a 6hp outboard on the back as a back up.

I drained the diesel out, ran it through a paper filter and put it back - and superdosed it with 25 ml of Marine 16 which is a bug killer and also claims to dissolve the residue allowing it to be burned through the engine.

Changed the fuel filter. Some gunge in the top - locals said that was normal for their fuel

 

then set off down the North sea... four days of being well shaklen.  I used two tanks of fuel.

At the end of day four or five the engine slowly ground to a halt, revs dropped away.  7.30 at night, dark, wind force 4 from the land and on the beam, foul tide of two knots.  No worries.

 

Classic symptons to blocked filters.  I fired up the outboard and finished the journey.

The  filter was a Delphi - bastard to get at - bugger  to re-assemble hanging upside down in the engine well like a bat in a cave.

 

upon getting home I fished it out.

diesel-bug-fun-Still003.jpg

 

the top of the filter had black slimy exudation blocking stuff on it - the consistency of  toothpaste or wet cat shit.

S5950001.jpg

 

Using a can opener I removed the top - this is also slimy.

S5950002.jpg

 

 

I pulled out the element

S5950003.jpg

 

 

I replaced the filter element and she ran for another half tank when again revs started to drop away.

I reckon I did this twice more at one tank intervals.  The boat was getting some pretty good agiation on the mooring when the winter wind came from the east and was against the tide.  I made no effort to keep the tank full as I figured this helped the shaking

I then removed the Delphi and replaced it with a Racor look-alike.

The boat has been running fine for two tanks of fuel, but I noticed the accumulation of gunge in the bottom of the water trap and some bits around the swirly job

So I drained the gunge  out and replaced the fuel filter - it was so easy compared to the delphi - thank you for that suggestion.

The marine 16 appears to have converted the gelatinous cat shit stuff to a fine deposit that catches rather well in the water trap before it ever gets to the filter.  I also dismantled the  filter to see what it looked like.  There is some black deposit on it but  it looks as though fuel was still flowing fine.

I am going to declare the marine 16 a success....... with the proviso that it takes time and agitation - I can live with the engine stopping as I have the tohatsu as a plan B.

access is a bastard

a real bastard

diesel-bug-Still001.jpg

 

this is the old delphi

diesel-bug-fun-Still003.jpg

 

the new top loading racor is better

diesel-bug-Still002.jpg

 

there was some crud in it - on the top of the inlet vortex jobbie

diesel-bug-Still004.jpg

 

and an inch of stuff in the bowl

diesel-bug-Still005.jpg

 

here it is in a jam jar - if you watch the film you can see that it swooshes around freely - the red colour is a mixture of red non road diesel and white tax paid stuff. Man that red die hangs around for ages.

diesel-bug-Still006.jpg

 

 

and this is the filter... not too bad

diesel-bug-Still007.jpg

here is the film of the swirling crud

 

I am now confident enough to remove  the outbord from the back of the fisher and move it to the quarter berth.

I think I have escaped removing the engine and tank.

It has worked for me..... and I intend to keep dosing with marine 16 until I go electric.

That last filter looks pretty clean.

I think you've got it beat!

Good news! And I hope you have many happy trouble free cruises in the near future!

Dylan, thank you for the update.  I'm glad to hear you prevailed over the buggery

Dylan, did you suck the crud out of the “Racor”,  or remove the glass bowl?

I just opened the tap on the bottom and it flowed out

 

it is a sort of suspension.....and flows with the fuel.  It left the inside of the bowl perfectly clean. The previous cat shit consistency stuff had a tendency to cling to surfaces.

 

Last night  I agitated the jam jar just to see what would happen and it took about an hour to settle down to the bottom again.

 

I will do a little trial,

 

I will decant the fuel from above the crud, put some fresh white diesel fuel in, agitate it and see if it is actually dissolves in the fuel over time..... as the people  from marine 16 say it will.

 

I have another water trap bowl on the feed for the taylor stove.  That is a second tank - about 2 gallons capacity I would say. That is fed via an electric pump from the second outlet on the racor. That also stood for seven years as the boat was in a marina and the bloke used shore power for heating. He told me the taylor did not work. The tank there got  infected and  also has a layer of crud in the bottom of the bowl but I decided to leave it there to see what happens to it as the marine 16 works throughthe system.. I think that as I am using the heater fuel  the layer of crud seems to be getting thinner. So maybe the marine 16 really does break down the old cell walls from the complex of 1000 different organisms that make diesel bug.  Damn I am learning too much about this subject.

 

Of course I have no idea how bad the inside of my main tank and heater  header tank are contaminated. For all I know the sides could still be dripping with the gelatinous residue waiting to slide down in giant gobbets that will envelope and block fuel out-take the next time I hit the Colne Bar at the wrong time.

  I also do not know if any crud is getting into the high pressure side of the  fuel system and is damaging the fuel pump or injectors.  If a diesel can handle chip fat then I hope it can handle partially dissolved diesel bug crud - which will all be compounds from diesel.

I know that my case is slightly unique in that the boat is small enough to be driven along by a 6hp outboard so the  main engine stopping has been no big deal

- especially as it starts to  slow down before it grinds to a halt so it gives me an hour warning before it  actually quits. Pleanty of time to whip the petrol tank out of the stern locker, connect it to the tohatsu, drop the bracket and fire it up.... it has always started second pull.

 

The fact that the boat is not in a nice calm marina but is on an estuary mooring and  gets rocked for hour after hour  when we have north easterlies should help I think.

(which we have had for about a month now and is unusual for them to last this long)

 

The wind has now gone back to the west - currently enduring a 24 hour 40 mph blow through here .... bringing warm damp air  and some welcome rain........

after tonight we have three quiet days of 10mph..... high tide is at 6.20 am at the bar so I have been given a three day leave. 

Life is  slowly returning to normal - Jill is doing a felting course......has her book group and walking group back under way. She says that it is still too cold to go sailing.

Dylan

PS 1 50 ml container  of marine 16 costs £16 via ebay.  I have now bought a 500ml bottle for £50.

Good news indeed Dylan! Every once in a while a 'miracle' product works as advertised. My OCD would compel me to get inside those tanks, whatever it took, for a thorough clean-out... but, given your distaste for fettling, I think the Marine 16 biocide was a successful alternative (though not without effort on your part).

easier than removing  the engine and both  tanks.....that is for sure.

I will not be leaving harbour without an outboard ready, to deploy.

The real cause of success IMHO is the filter/seperating bowl. Biocide is good, your fuel tank should not be a Petri dish. Cleaning out the tank is good but as discussed, Dylan's boat has access issues (this is unfortunately common). But miracle glop that "dissolves" crud into your fuel is not good, injectors are fussy things and often act up with clean bright fuel. Try and feed them "dissolved" crud and they are sure to feel put upon.

so far so good on the fuel pump and injectors - I will let you know if I get a problem with them

The Marine 16 certainly appears to have seriously altered the form of the residue - it has gone from a pipe and filter clogging cat shit to a light suspension that barely impacts the colour of the filter and no longer chokes off the fuel supply. I falls out the bottom of the water trap...... the other stuff clung on in there

I am happy and am off back into the north sea in the morning.

Dunno yet

4th surge is a worry....

And the boat has some issues

Mostly electrics, water leaks, and gear box at the moment.

I have also bought 3 toppers, two canoes and have two rowing dinghies for the entertainment of a string of young relatives and their friends who will be camping in our garden this summer.

All the campsites are full so we are opening our garden, shower, bog barbecue, fire pit kitchen and boats for general family use.

I aim to get to know the Thames estuary....

Defeatist talk, head North. I’m planning on getting to the Western Isles in July if all is well. Keep the videos coming I’m sure you’ll find some interesting topics in the Thames estuary.

What the hell is a bog barbecue?

I'm not sure I really want to know all the details.

Several neighbours got their boats stuck on the wrong side of the border this year...

The thought of 4k of marina fees on a slowly sinking boat is too scary to  contemplate

I have always wanted to see the Thames estuary at spring lows when the five giant sandbanks are exposed

We were motorcycling through Spain in the seventies, came across one of those vans in a campground.

A young English couple heading home after crossing from Morocco via Gibraltar.

It was packed full of tins of condensed milk bought in North Africa, they said they planned to pay for their trip by selling the milk when they got back to the UK.

That was when we understood English cuisine...

sounds a bit fishy to me

 

Morocco to UK with condensed milk.....

 

the UK with 40 inches of rain,knee high grass,  a massive dairy industry

hardly any weed for sale

 

and they are importing condensed milk from Morocco where the weed grows shoulder high and they have a very poor dairy industry...

 

I fear you were being sold a pup by some drug dealers.

 

 

That aside....

 

just did 80 miles in arough old nborth sea incl;uding two hours sat rocking around outside the Deben bar waiting to get back.

 

not a trace of diesel bug residue in the filter.......

 

woo hooo

PS my dad was an ammunition truck driver in the artillary during ww2 - el alamein and then Monte Casino

He was stationed in Italy beside an American unit.  He startedshifting truck loads of Bully beef(which the brits harted but the Americans loved)  to the Americans in return for truckloads of american condensed milk (which the Americans had too much of and the Brits loved.

He stayed friends with his American buddy right until  the ends of their lives..... my brothers kids are good freinds with Mort''s kids .....
