My Boat; building a 40 foot shanty boat / houseboat. 6 ton + to cruise the Murray River in South Australia.

I have the floats (plywood pontoons) built, and currently working on setting them up level and plumb, to fit deck beams and floor.

We are located about six miles from Mannum, in South Australia.

mannum

The town is regarded as a center for holiday houseboats.

There are approx.300 holiday hire boats based here, and a small support base for the design, building and maintenance of these craft.

The vast majority of these boats are outboard powered steel (or more recently alloy) pontoon boats.

My build is plywood on frame, so it`s not all that common, but there are a few smaller private boats built similarly.

The design of this boat is a result of some consultation with some local builders and owners of similar craft that have given good service in the past.

Now normally would always seek out a good suitable stock plan before starting a build , particularly of this size but after looking a long time , even on the internet , there appeared to be preciously little on offer.

The closest I found was an aging design by Glen L (US) called the “Mark Twain”.



This design came close to requirements, but the layout and payload (displacement) was a little less than I was looking for.

The other boat of interest was the Botel 40



This design is by someone calling themselves Key West Boat Works, but after several emails and attempts to contact them to order plans I have yet to even get a reply.

I have since moved on.

So, it seems a long winded answer but I thought I would explain how this design came about.

I will scan some drawings when I can.

The engine mount for the outboard motor has been completed.


Bolting up the steel channel and more shantyboat plumbing.
by: Harry

Work on the holding tanks for the shantyboat continues....


Working on the Tank Straps.
by: Harry

The straps to suspend the waste water tanks for the Shantyboat are now complete.

As this is a fresh water boat , and I could not get galv. flat bar without a lengthy wait,
I used 2x 1/8 Inch ( 50 x 3.5 mm ) mild steel.

The 1/8 inch thick flat bar was easy to cold form around a simple wooden former , and any minor kinks were lightly tapped out using a ball - pein hammer.

Three coats of Kill Rust primer and two top coats of oil based gloss paint complete the finish.


Waste Water tanks

Two month break is over , now it`s onto Waste water tanks.
by: Harry

I had a two month break, lots of frost and ice this year, too cold to work outside.

things are warming up (slowly), so its onto waste water tanks ..........


Last of the interior shelving
by: Harry

This is the last of the interior shelving to be fitted to the cabin space.

It's supposed to somewhat resemble the look of the old style luggage racks that was often seen on trains and tram cars in years gone by.



Some progress
by: Harry

Its cold here, painting out the rear cabin of the shantyboat is slow work.

Shantyboat progress , rear cabin.
by: Harry

Hello Mike , and all following.

Progress is slow , but I have managed to do some work fitting out the rear cabin space.

Another bed base is assembled and painted , and has been fitted in place.

Shelving to house some audio visual equipment has been made , and some wall cladding fitted ...

Two small glazed cabinets are being assembled ready to fit in place.

Small items for the Shantyboat
by: Harry

Making the numerous small items for the Shantyboat takes up quite some time.


Colder weather is coming....
by: Harry

Hi Mike ,

Those little drawers are more work than the bigger items , and as the weather is getting colder here and we head into winter , things are slowing down again.

Glue and paint is taking longer to dry ....still , what can you do ...just keep going the best you can I guess .

Thank you for stopping by , I appreciate the comments.


Lockers

Wow, love those lockers Harry.



Looking Great

Bored?
by: Mike

Not in the least bored Harry, you are doing such a superb job


Hi Mike.
by: Harry

Hi Mike.

Thank you for the comment.

Thought you would be bored with this build by n0w LOL.

John Guest plumbing : So simple it`s ridiculous.
by: Harry

The Shantyboat is getting plumbing.

These John Guest push on fittings make connecting the plumbing a snap.Lighter, faster, and cheaper than copper.

Stern construction
by: Hans Karbe

Hello,

very good project! I learned a lot for my next project.

My houseboat "Brixholm" has a similar stern.

My experience is, that a flat stern at a boat that is no glider reduces speed and take a lot of fuel.

It is better to have a conical stern.

I construct 2 pieces and will put it on my stern in spring.

You can see my houseboat in "youtube" and my name.

Photos of the conical stern I have, but I can´t send it on this place.




Thank you
by: Harry

Thank you for the kind words wilddingo.

Happy to see you enjoying the posts of my humble build.

While I have tried to take some care ,I can assure you that I am certainly not professional boat builder.



Fantastic!
by: wilddingo45

You are clearly no amateur.

The care and skill of this build shows in every detail.

Thanks for sharing it all.


Foam flotation.
by: Harry

Hi again Darryl,

Regarding foam flotation :

On hulls this large I would not do it.

Here are my reasons :

To fill these size hulls would add a considerable amount of weight. Foam weighs more than one would think.I robs you of payload. Pontoons are already somewhat weight sensitive.

Cost would be considerable.(large volume to be filled.)

Lastly, and I think most importantly :

Any water entering the hulls for whatever reason, be it damage / leakage or condensation, would be trapped under the foam , and the water would remain there, potentially causing rot.

Inspection would be near impossible, and repairs would be much more difficult.

So, in short I sincerely believe water tight bulkheads are recommended, but no foam.

Clean , empty plastic canisters / bottles are a possibility, but I don`t believe necessary.

Best of luck should you go ahead Darryl, and be warned , it`s a lot of work :-)




Water tight bulkheads.
by: Harry

Hi Darryl.

I think it would be wise to incorporate water tight bulkheads into your design.

Most of my bulkheads have circular cut - outs.
Some of these will be sealed watertight by fixing
in place over sized circular blank off plates cut from marine ply.
There will be eight separate sealed compartments in the two hulls.

I also have eight access hatches placed in the floor inside the cabin, and a further four on deck outside.
The hatches will allow the hulls to be vented enough to provide a dry interior if any condensation forms inside.

I hope this all makes sense Darryl, thank you for the questions, and your interest.



HOUSEBOAT
by: DARRYL

HI I HAVE BEEN THINKING ABOUT BUILDING A PLY PONTOON HOUSEBOAT SIMILAR IN SIZE TO YOURS.

BUT WAS GOING TO MAKE EACH BULKHEAD WATERTIGHT AND FILL WITH FOAM AS I SAW ONE ON UTUBE SINK.

DO U THINK THIS IS NEEDED

THANKS DAZ

Hi Paddy
by: Anonymous

Hi Paddy

I accounted for the weight of the pine framing
(2x2) and then added some 20 % extra displacement in the floats by making them 150 mm ( six inches ) wider.

It`s difficult to come out on weight , and almost impossible to end up " light."

Going " really light " using exotic materials was beyond my budget.

Thanks for your interest, it`s appreciated.



this is terrific!,
by: Paddy

Just ran across this.

This is really a great thing your doing by sharing the build with those of us who dream to do this.

I have only one question, did you consider using metal studs on non weight bearing areas?

So much lighter than pine or spuce.. just wondering.... all the best!!


Thank you Andy
by: Harry

Thank you for the kind comments Andy.

Re the hull shape : Precisely my thoughts Andy.

I always thought it was a waste of money dragging a stern wake behind a boat that will travel at a rather sedate pace.That`s what speed boats are for................ :)

The inspiration for the cabin came from the San Francisco cable cars , even Melbourne trams.

I have always liked the look of those and this is an attempt to get a somewhat similar look.

I think there is a resemblance , even if rather loosely.

We wanted lots of light too and dislike that
" floating Esky " look often seen.

Thanks again Andy , your comments are appreciated.




Lovely craft!
by: Andy Wilson

G'day Harry!
Congratulations on a fine addition to the waterfront scenery!

Two things make your craft stand out from the awful floating boxes seen elsewhere....the first is the lovely sweep of the bottom curve down from the bow and back up to the stern.

This will pay off endlessly in fuel economy and reduced wake.

The other is the vintage feel of the upperworks and the attention to period detail.

I guess this is a nod to the existing historic vessels around Echuca....or maybe just because it looks so damn good and will never tire of giving pleasure to the occupants.

Cheers!
Andy

Message for Clive Webb
by: Mike

Hello Clive,

This is Mike (DIY Wood Boat) I have a private message for you from Trish and Harry.

If you would contact me using the private contact form here I will pass it on to you.

Cheers,

Mike



Hello Clive
by: Harry

Apologies for the delay in replying Clive, sometimes " life " can get in the way of best intentions..........


It sounds like you have plans ....I`m no expert at boat building Clive , but can only say this :

DO IT NOW ,

as it all takes three times longer than planned.


First contact...
by: Clive Webb

I love what you are doing, the design and your craftsmanship.

Although, I'm a boating person at heart, I lack boating experience and have only ever made a couple of rented houseboat trips on the Murray.

I would like to continue to follow your progress as I'm retiring next year and have always planned to build my own boat in retirement.

Although, I have a lack of boating knowledge, I have worked with timber all my life and can't imagine not building out of it.

I am currently working/living in NSW, but have bought a property at Borrika, not far from Mannnum.

Perhaps when I relocate I would be able to see your craft and meet you in person.

Kind regards,
Clive Webb...



Awesome project
by: mike@BuildaHouseboat.com

When last we talked on the net you said you were going to build a site about your boat project.

Well, It's great.

And so is the boat. I love the pictures.
Congratulations.
Mike


Roof
by: Michael

That should keep the rain off Harry.

You'll have to call in the interior decorators in soon.


Thank you
by: Harry

Thank you for the encouragement Mike.

I feel like I`m getting closer ( to finishing that is ) .....guttering is being fitted at the moment , then roofing.

Rain expected this week, but spring is in the air for us down under.

Hope to have some real progress photos soon.


Great Work
by: Mike

She's looking good Harry!!
