There are of course plenty of sources of lovely stainless steel chimney systems with all the relevant fittings you should need, and Energy Solutions might be the obvious choice, particularly given your location, but the costs always seem to be eye-watering, as much again as the boiler!
This may be a half baked (?) idea but I have just been looking at a junk rigged yacht where the intended masts are lamp post standards. These are tapering galvanised steel, 3mm wall, press braked rather than rolled tube, about 230mm diameter at the base and 100mm at the top, but of course about 10 metres high. A call to your local highways department might establish where the old ones go, and the appropriate section might give you a nice tube through the wheelhouse, welded through the wheelhouse roof and sole, which might just give you a nice c. 120mm male external collar for an external double wall stainless flue, and a nice 120mm female collar in the engine room for a double wall stainless primary pipe from the boiler, subject to length..
Obviously you would have to paint the tube interior where welded with say cold galvanising paint, but our own galvanised external flue is of light duty tubes only, two concentric pipes with fibreglass rope wrapped between the two, and has lasted something like 20 years to date so 3mm galvanised might see you out.
You can buy new lamp posts from a place in Nottingham (I can look up where if you are interested) but there should be nothing wrong with used ones in the area of the pole that you would be using.
Just a thought. Might spur better ones!
