It is sacrificial chine protection. Yes, but OP was asking for the definition of a 'chine'. A chine is a change of angle. Whether or not it has a sacrificial edge does not help the definition, does it? You are correct, but so many people refer to the chine protection as a sacrificial chine it is helpful for the OP to know this. If he hears the term in the wild it will probably be referring to the bit that isn't actually a chine but just protecting the chine.

Thanks for all the input guys......I will try not to light the blue touch paper again. Seriously I do appreciate the input as I have said I am at the beginning of this process. phil

On your hull the bits of the bottom plate that should have been sticking out to protect the welds where the sides are attached, had worn by bouncing off things. the wear was worse on the part of the bottom plate curved in towards the stern. Along this bit, extra bits of steel should be welded to the bottom plate to replace the worn bits so as to protect the welds.
Any clearer ? (If it isn't blame it on the bottle of cider I've just had !!!)

Not sure if I've understood it correctly, but this is what my survey says... Hopefully, if you read my post 3 prior to yours it will help you to understand that survey report. You'll note that the surveyor says 'sacrificial chine or wear edges...' He then goes on to tell you where yours are particularly worn and where they could do with new steel welding on. John gives further explanation with...

As it was me who used the word chine I should mention that my boat is a modern barge which has vertical sides down to just below the waterline then a 45 degree "chine plate" which leads to the baseplate which is flat. This makes the boat slip through the water very cleanly but she rolls terribly on the tideway. It does result in loss of floor space so probably not very practical on a narrow boat - it has been done I believe.
I said "chine" I should have said "chine plate"
Or maybe that's also incorrect.

The main proponent of chined narrowboats were the much loved/maligned Springers,
From a pure engineering and manufacturing point of view a much better design than the modern run of hulls. The chine plate being folded, gave a more rigid construction than flat plates but with a thinner plate, also allowing less framing but greater "stiffness".
Love them or hate them they introduced an enormous number of people into narrowboating and there are still an awful lot of them around especially when you think that a lot of them were built with steel thinner than some modern surveyors, insist needs re-plating.

Springers were vee bottomed. This is a bit different to chine plates and a flat baseplate. Not sure how the latter is described. Is it "hard chine" ?

same same both are "hard chine" this describes an abrupt change of angle as opposed to a gradual change (rolled or curved bilge plates) You can have single chine (V bottom) to multichine the number of them doesn't matter...................... At first glance this looks like a round bilge but if you look closely it is composed of multiple steps. Nice looking barge in a floating drydock in London by mudlarker2, on Flickr
