Would you buy a boat from a builder who puts opening ports back to front? (opening out instead of in).

How much of the past 20 years has it spent in the water? (certainly won't corrode much while sitting on the bank).

Has it ever actually had an engine installed?

Brings new meaning to the term 'shiny boat' :)

 

Can't help thinking the £££££ would have been better spent restoring a rotten but historical hull (or 'hulk').

 

cheers, Pete.

Hi

This is out of my price range but I'm intrigued by it being stainless steel

 

I can guess the pros with a stainless boat- but are there any negatives?

stainless will not take the rough and tumble of canal life! Too much banging and bumping creates brittleness either side of welds which then lead to cracks. Wont rust though!!!

Depends on the stainless, battleship armour plate could certainly take the rough and tumble and it was stainless

Its done 15 years so far

from the back the handrail seems to just be a continuation of the cabin side it hasn't been boxed like you would normally see. to me this indicates a generally poor unfinished boat. from the front it seems to be box section.

 

has it ever been in the water?

 

 

 

nice idea but there is a good reason canal boats are mild steel.

Where on earth did you get this information from?

304 or 316 has the approximately the same mechanical properties as mild steel

I can't understand why they used S/S for the whole thing, when only a quarter of the boat is actually in the water and subject to corrosion, welding Stainless to mild is not a problem, and would have saved alot of money. it's quite sexy though, if you've got money to burn.

maybe it is in fact aluminium :lol:

I never had a problem with 316, just a bit harder than MS and stiffer to bend, design wise just the same. The boat would not have been made with plate apart from either 316 or 304, duplex SS plate is available but the price of more exotic material would have been out of reach. I have never heard of ferritic SS plate. I don't trust duplex SS welding in a flexing environment and would not use this material in a hull fabrication.

Aluminum is not a SS and I would never buy an Al boat.

Building a composite SS and carbon steel boat would worry the life out of me, if the join (inside and outside) could be guaranteed to be separated or protected then maybe. Naval vessels with MS hulls and Aluminium superstructures had to have specialised connections, with no metal to metal contact allowed, anywhere.

I Must say, that i have never read such a load of nonsense. It is a good job "Sea Otter" took no notice of the negativity produced when they designed and built their superb Alloy narrowboats.

Just because Narrowboats have changed very little since they were horse drawn (apart from the internal luxuries) there is no reason they shouldn't be changed if not only for better handling.

The stainless steel boat will be far more durable, with a lifespan far longer than my own. As long as it is fitted out properly and metals are not mixed, there will never be a problem, and never a corroded water line.

And if Stainless hadn't gone through the roof during the time "We" built this one, then we would still be producing them, but after this one, it wasn't financially viable.

This is a boat for life.......

Yes some people (as usual on internet forums) were talking out of their backsides, based on no real knowledge of materials.

 

The main reason modern narrowboats are made from mild steel is because it's relatively cheap compared to non-ferrous metals.

Crevice corrosion/cracking is a risk in saltwater, much less so in freshwater.

 

Its likely to have been built by a more skilled fabricator than your average steel tube.

 

Wouldn't worry me in the slightest.

Because mild steel is cheap! Only reason

Thank you. I built it! 👍

Mixing stainless with mild steel is asking for trouble. And why on earth would anyone in their right mind want a boat where half rust and half doesn’t?
Half you have to maintain and half you don’t! 🤣

No negatives I built it in 2000 and it will live long after I am gone
