Narrow boat plans.
« on: September 28, 2016, 03:27:42 PM »

hi guys, I know this is a long shot but has anyone got any plans for an old working type narrow boat
/ canal barge, the type with coal fired steam engine and coal cooking range etc.
That I could borrow to copy or buy, any costs would be covered or a donation to the R.L.N.I would
Be made.
P.S. Any photo,s would also be a great help.


Thanks for reading.

Thanks klunk, I could only find the plan view on that site.

Check out https://severnerwillow.wordpress.com/  There a drawing/plan in the history section.

I googled "steam engined narrowboats" and came up with a photo of the Fellows Morton and Clayton boat "Monarch" about halfway down the page.

https://www.waterways.org.uk/blog/evolution_the_narrow_boat

Stem engined boats had a very narrow lifespan due to the extra boat space the engines took up...normally all steamers were working a fly boats,,ie: they didn't stop..ran night and day.
The site also has quite a few pics of working boats
hope it's what you were looking for.

What a fantastic history the narrow boats had, I never realised how many different type of
Boats were used. All I have to do now is to decide which boat to build  {:-{


Many thanks guys for your input.

Hullo John.....I do agree, there are some beautifully depicted & painted images and videos of full sized narrow boats available on the WEB and not just from UK, but also from the Low Countries of Continental Europe

However careful consideration would be needed with respect to scale, as the small beam to LOA ratio combined with the very shallow draft would make a very difficult R/C scale model to build..... and.....get it to float %)

If you could achieve floatation, the turning circle  {-) would probably only then be a secondary concern

Thanks for the warning Derek, I will make the hull first with a lead bottom and add drop keels
If needed to stop it rocking. What do you think? If it's no good I will have learned through the
Process so not a complete waist of time.

I'm sure the model would be fine in a really narrow lake%%

I have seen pics of model narrowboats actually on the canals O0

Another factor would be that the steam engined, and indeed a LOT of the earlier diesel engined boats, were converted from the original horse drawn boats.

Although not to scale, I could fit bow & stern thrusters and just make the hull a little deeper.
The dummy steam engine I thought I would copy Ron Rees,s idea in Octobers MBM?
That will leave the boiler part which will have to be an upright version due to the limited room.
It will be a type of traditional fly boat I may have a go at over the winter months if I can find
The information I need.

John......have you considered the hull dimensions?

For example, a model Narrow Boat hull [with blunt ends] 1000 mm long x 100 mm wide and having a draft of 25 mm....will provide [1000*100*25] = a displacement of 2.5 kg O0...[or say 2.3 kg with a semi pointy bow & a rounded stern]

This means the complete hull + superstructure + engine power system + R/C gear cannot exceed this same 2.5 kg given the hull and draft dimensions %)

However lets think of displacement as being cubic or 3 dimensional...... so a hull twice the size [2000*200*50] will displace 20 kg

So from this, it would appear that the 1000 mm long hull could be built, but would have difficulty in maintaining buoyancy [if fitted with engine & R/C gear], however the 2000 mm long hull could support a far greater mass at the expense of transporting a longer model

Either way, I don't think you would need a drop down keel of a great amount of ballast.......we must also remember all vessels of quasi dimensions need a low centre of gravity [metacentric balance]

Good luck :-))......Derek

Nearly all narrowboats carry some form of ballast in the bottom.
early ones would have had lumps of cast iron, later ones were either bricks or paving slabs, to keep the main weight as low as poss.

Narrow boats are 6'10" beam and up to 70' long
Narrow locks are 7' wide.

Ok guys you have talked me out of it, would not be stable enough on our lake any way.
Thanks for your input, I will look for another project to keep me sane over the winter
Months.

It is perfectly possible to build a narrow boat for sailing on a lake. This one was built by a member of the Cambridge Club. Not sure if it was scratch or kit but its a manageable size and sails well. It wouldn't be difficult to modify the superstructure to a working boat.

Thanks for that Barri, but I'm afraid our lake is never as calm as the one in your photo.

Hey guys,


I'd like to just throw my 2 cents in from across the pond. I built a narrow boat based on the Orion Mouldings 59" hull. Nice hull. Basic 2 channel operation, with the third channel operating the smoke generator, and I'm using a single cylinder engine sound unit. Model runs great. I'm using a small 12V "mystery meat" motor, and a 15amp esc. Here is a video of the model running (forgot to turn on the smoker  :(( ).

Hullo Mark........thanks for sharing the video of your narrow boat based on the Orion Mouldings 59" hull...she looks fine on the water and the steerage is clearly very responsive :-))

I see from the Orion WEB site that the hull is .... "1/12 scale English narrow boat, using an Orion Mouldings fiberglass hull and 59" X 6"

It would be interesting to understand the vessel draft and total weight

A 66 ft x6'10" x2' narrowboat would be around the 15 ton mark.
BTW the Orion is 59" x7" not 6".

Derek,


Thanks for the compliments. The model draws about 2 1/2", and weighs about 15lbs, 5 lbs of which is a 12v, 7amp gel battery, which sits amidship, and about 1lb of lead weight in the bow.

Mystery meat? That is an interesting name! 

Lovely narrowboats by the way. I like how you can really go to town on the homely details.

I used that term because there was no markings on the motor's can, it just came out of the parts box. I always use "mystery meat" to describe items of unknown origin  ok2 . I prefer to build in 1/12th scale, so to use dollhouse miniature items when possible.
