We have now completed installing the ceiling boarding right through the boat and primered it as far as the tug deck.
The cardan and prop shafts have been installed as have the battery and fuel tank breathers.
The Kabola flue was installed "dry" but then removed to allow access and further work in the area.
To facilitate a bend and improve the integrity of the flue (to contain exhaust gases) the top join through the deck fitting was cut and welded rather than use the standard adjustable fitting.
This meant some careful measuring and (nervous) cutting of the (expensive) twin wall stainless flue kit before taking it to a local TIG welding shop for reassembly.
I will add photos of this later.
