Toesup Boat Werks News Release.

There has been the wood, the ply, the glass, the perspex, the foam, the steel.. and the aluminum Springer…

Seeing as the TBW is always pushing the innovative limits and tugnology of the Springer class, I was trying to think of an advanced material that was cheap and easy to use and yet strong enough to stand up to the rigors of Springer football. While I was out at Lowes the other day looking at different materials, suddenly in the construction isle, I found what I was looking for.

Ladies and Gentlemen, the TBW is proud to present a world FIRST.. the worlds FIRST and only Reinforced Concrete Springer….

There is a layer of chicken wire within the concrete, adding strength and holding the concrete together, and within the concrete there is some foam to be cut out that will allow for the gear.
There needs to be some filler here and there as the surface is quite rough… or I might just leave it ‘as is’… the ‘rough and ready’ look…

Tonight’s floatation tests actually look quite promising…

I look forward to seeing the trimming and ballasting tests.

A springer ramming game could be fun.

Question.....

did you "vibrate the air out of the mix when you poured the mould".

I believe that concrete is porous, so a sealant is needed

I foresee a less than perfect "Umi launch" with that one.....being an expert on the subject myself

Will it sail like a "Brick"

Toes,

I hope you have read the instructions on the inside of the hull? Building codes must be adhered to, and avoid heat as its combustible?

Just a fancy shaped lump of concrete. It will sink!!!!

tigertiger · « **Reply #7 on:** April 01, 2009, 12:31:47 pm »

They do build boats out of concrete. But the walls are relatively much thiner.

I'm looking at the date with a very inquisitive eye.

There is a concrete barge at E'Port Museam , thats still floating I believe..

You are going to video the launch I hope.

There was 8" of water in the tub at the time of the picture...

Andy...sharp as a button

Wonder if anybody else noticed.

As it has gone 12:00 has the April fools gag ended yet?

Toes,

Please see Mrs. Toes she has your medicine and knows how and where to take you so you can have a long and safe life.

Next question, how many glasses of the Scottish amber liquid have you had be for thinking this one up? And you need to share some of that liquid!

Now I have noticed a couple of problems, first you should have installed the stuffing box and the rudder tube before you cast the hull. How are you going to secure the deck to the hull? When are we going to see it in the water not just floating in the tub, because in the tub you could have a block of foam under it to make it look like it is floating. I don't want you to be cheating here.

that's it, you've solved the problem of our deep recession and the crisis in the construction industry all in one easy go.

get them diversify into building concrete springer hulls.

brilliant of you, toes. lol

OK.. I'll come clean...

Yes, It was an April Fools gag.. The Concrete Springer is virtually solid concrete, there is no reinforcement in it, that was just for the picture.. and it weighs in excess of 30lb.. so no, it wont float.
The pic of it in the tub... it was ballanced on a glass that doesnt show up in the water / picture.

dreadnought72 · « **Reply #17 on:** April 02, 2009, 04:54:12 pm »

Good one!

It was the size of the foam relative to the s**tload of concrete that made me smell a rat. But (thinner) concrete's maybe not a bad idea for large tug-towing hulls. Cheap enough.

Andy. Do I win anything?

At some level it ought to work.

Back in the 60s Windboats in Norfolk built a series of river cruisers using a version of concrete they called Seacrete. There was one of them on the quay at Burgh Castle Marina a few years ago. The guy who was cleaning it up was amazed I knew what it was, it seems there are very few of them left, which raises the question 'How the devil do you scrap a concete boat?'

Colin Bishop · « **Reply #20 on:** April 03, 2009, 11:06:58 am »

Many full size yachts have been built with ferroconcrete. It was quite popular at one time as a way of getting a cheap and easily repairable boat. however the non standard nature of the construction makes them hard to insure.

The little Clyde ferry that used to run between Largs and Millport,the 'Keppel',was a concrete hulled boat.

Strangest Subject i have come across however concrete boats are more common then you might think!
commonly known as Ferroboats. These links might get your cogs thinking for a new project

Not so strange - from my window I can see the River Coquet estuary and Amble Harbour
where in the 1920s they built concrete boats and there is a 45ft yacht completed up to deck level
made of ferro-crete (concrete over a wire and chicken wire frame). Apparently it is a good medium
for amateurs to build cheaper larger yachts. If it is done well you get a good boat but nobody ever
seems to buy second hand ferro boats unless they saw it being built as the surveyers can't do a
a proper survey on the hull like they can with GRP or wood
I didn't beleive it either before I moved here.

In OZ....the Government produced dozens of [ferro cement] DUMB lighters then of gave them a CAL pennant reference....I can only assume CAL stands for Commonwealth Ammunitaion Lighter, many are still in service today after 60 years service

The attachment depicts CAL 501 & from the mooring appears to be westward up river from Cockatoo Island...........you can just make out the Sydney Tower in the distant background above the 5 in the pennant number ..................Derek
