Diesel tank is right at the stern. Then we have 2 large plastic boxes holding all the bits and pieces you find you accumulate to repair and maintain the boat plus 3 tool boxes, because the space is not big enough for one large one, plus an aluminium case holding a voltmeter, interface for the Victron, and such things. Then I have the engine with the batteries on one side and generator the other. In front of that and under the generator are a spare alternator, repair kit for the Webasto and a box with spare filters, etc. In between all this is a 5 litre can of oil, a bottle of distilled water and a hydrometer. 

Space for clothes!

Hallo pearley,
with my design, the engine room (3,4 m long) is near the middle of the boat, there all these parts will have to be stored, there will be room enough.

All the space under the back cabin and cockpit is accounted for, just for the last 3 feet of the boat I look for a good use.
As said, a tank would bring the stern down too much. I’ve already balanced the tanks between foreward and aft.

To size the coal bunker (approximately) what are the standard dimensions for coal bags?
– weight 10 kg
– weight 25 kg

– or any other size usually sold on the canals

Approximate dimensions would be enough. Thanks

I can only help you with the 25kg I’m afraid… and because of you I’ve just reorganised my well deck, brushed the front door mat and wiped all the coal dust away. I only went out there to measure the coal bag. It’s 28″ x 20″.

Another popular size is 20kg. I can’t help you with that either!

Thank you very much Paul,
this really helped, I would have been out by maybe one third of the dimensions.

Now you also have a tidy well deck again Laugh
(do I owe you one bag of coal?)

I had a tidy well deck before but it’s spotless now. I’m gearing up for next year when I need to be able to carry far more coal on board rather than store the bags on a pier next to the boat, because I won’t have a pier next to the boat if I’m cruising full time. My solution has been to split each 25kg bag into two robust plastic bins. I have ten bins now, four in the well deck and six (hidden) inside the boat. The five bags will last me two weeks.

For steam power 25 kg would be just enough for one half to one day steaming.
That is the reason why I am so niggly with space, coal takes appr. twice the volume than diesel and you have to carry it to the stowage instead of pumping.

Steam plants is a hobby for crazy people … SurprisedWink

I am wondering why your not going for a flash boiler using diesel oil. Surely a flash boiler will get up steam faster and be more controllable using diesel as the fuel?

Ha! Paul has deleted the spamm0r. SurprisedLaugh

Hallo GM,
you are right, a flash boiler will get steam up very fast – but it looses pressure as quick.
A diesel fired flash boiler will need a certain amount of automation which can get complicated and/or expensive.

I have a design of a watertube/firetube boiler with enough storage capacity that I can turn my back for at least 10 minutes
and this all with manual control. A very small boiler of this type is at present in the final design stage (90% complete), this will
be scaled up next year by a factor of three for the narrowboat. I have a very good professional boiler manufacturer for this,
I will get a quote for the fabrication in January or February next year. I will then post some information on the boiler.

This boiler will be solid fuel fired (coal and/or wood) but it could be easily converted to diesel firing – so I loose no options.

Getting steam up from cold will take appr. 3/4 of an hour, so do it before breakfast and take your time.
Getting steam up from warm condition the next morning will take appr. 1/4 hour (very short breakfast Laugh )

I have tested these times in summer with a 25 HP boiler (for the 42 ft steam launch) and they are realistic.

The boiler design is one of my least worries, the layout of the boat itself is much more complicated than I would have
imagined at the beginning, but that is half of the fun to do a difficult job right at the first try (more or less I hope).

Of course I have checked all the information available on the few steam powered narrowboats and taken what I would like to use.
Everybody has his own design philosophy …
