Fishplate

[lpp2]

Good evening

Been looking at one or two boat adds, found one saying the boat had new fishplates, I'm fairly sure these have nothing to with food serving but what are they? what do they do? anyone got a picture.

No idea.

 

Fishplates are/were used to join pieces of railway track together, with big bolts.

I suspect someone writing the ad has got their terminology muddled?

Seconded.

 

Hard to imagine WTF fishplates on a boat might be. But it indicates to me the vendor is not familiar with narrowboats, and consequently calls into question everything else he says about the boat in the advert.

 

Tread with utmost care here, verify everything!

Is it Harebell? (Linky to BWML Sawley)

 

For me, this just about epitomises Sawley Marina's expertise

Reckon youare right about whoever wrote the advert not knowing what was what, howver it may be that they are pukka but just a bit ignorant. A chap a few boats along from me is just clueless, insists on calling his pram canopy a Cratch and his hull sides as his gunwhales also calls his doors French Windows

I agree.

 

From the ad... "Resiting of propeller including new Boss, Fishplates and Stern tube, April 2011."

 

This is total bollocks, penned by a caravan salesman without a clue, I suggest.

 

Wow this NZ Marlborough SB is good... "Explorers" from Co-op local stores. Honest!

mate i made my own barge i even did the pointey bit and the blunt bit at the back..i recon fish plates are the bit that stops fish getting dragged into the fish mincer on the pointy bit, think there for people that cant drive the barge very well

[MtB]

think there for people that cant drive the barge very well

 

Malcolm Burge gave me a bollocking for saying that. It's 'steer', apparently!

Yes that's the boat I was looking at, to be honest it confirmed my own thoughts, wouldn't you think they would get sales brochures right!! Thanks for all the comments.

Are you sure it isn't a Meccano boat? Fishplates

[majorminor]

FWIW, a "fishplate" in shipbuilding terms, refers to an angled section, as often seen edging a deck. They are also used at any number of places within the ship.

 

Here is a quote from a ship's spec sheet:

 

To avoid cargo flowing around the accommodation/poop deck,
a transverse fishplate shall be arranged at the aft end of the cargo
area. At the outer end the transverse fishplate shall have the
same height as and be connected to the aft end of the gutter
plate.

 

So it doesn't necessarily have a railway connotation, and someone other than the salesman just might be "talking b*ll*cks"

Very interesting so it also has a variable pitch or folding prop. Highly appropriate for canal use Otherwise how can they fit a new propeller boss to the old blades!

 

Also in my view a load of what MtBM says. If really interested best contact the vendor and ask for WRITTEN clarification of exactly what was done. That quote could mean almost anything.

I understand the fishplates are the horizontal plates added to a nutty stern when motorised, to aid water flow around prop and rudder.

I was especially intrigued by their claim that the propeller had been 'resited'. I wonder where it was before the work was carried out.

Good point, I think you are right. Often fitted to a butty too, when motorised.

 

More precisely, they are to stop aeration of the blade, where it sucks in air from the surface, and often termed 'anti-cavitation plates'.

 

Aeration of the blade should not be confused with cavitation however. Cavitation is a different thing.

Being of a (slightly) charitable nature, also mindful that terminology changes by area in what is a craft industry -

I read the advert that the sterntube has been replaced and possibly because the original mounting area in the hull had rotted, it's all been replaced and rewelded?

 

Fishplate may not be the appropriate term as a narrowboat hull is generally one (welded) piece.

 

Does that make sense?

 

 

[Captain Fizz]

I have used old fishplates of the railway variety as ballast in the past and very good they were too.

[Speedwheel]

Yep, that's what I've always know them as. To prevent cavitation.

If you really fancy the boat then mail them for an explanation. The boat looks clean enough and as though it has been well cared for. However, it does appear that the selling yard have attracted some negative comments from site members and this should also be considered.
