LIGHTSHIP CORMORANT / LADY DIXON - Chapter 11



CHAPTER 11  -  24 Oct 13

With Winter approaching, young men’s fancy turns to – dryness and warmth‼ Because most of the teak decking has long gone, there is only rusty metal plate between the cold night air and the (future) living space below deck. Condensation is also quite a problem and because the drain holes are above the plate level, there are all sorts of leaking opportunities when it rains. Hopefully we have a cunning plan which will solve both problems. The sides of the ship are a separate project!
I related in Chapter 7 how the plan was to fill in the space left by the absent decking with a thick layer of all-weather ‘tennis court’ surfacing. This was going to be very difficult (the deck has a slight curve to facilitate drainage and following that curve with a fluid whilst maintaining a constant thickness …. need I say more?).
So now Simon is being advised by a professional roofer and a more complicated, but more feasible plan is emerging. Looking at the more difficult part of the deck – the curved walkways down each side, which have light-boxes built in …..

First the deck will be given a coat of primer. Then short lengths of timber, about the thickness of scaffolding-type planking, will be wedged across the walkways, at 5ft intervals, between the superstructure and the wide baulks of timber which edge the ship. The intervening spaces will be filled, to the same height, with roof insulation panels.


Then bitumen is poured into all the gaps
 
Sheets of marine ply are now laid over and secured to the planks. The surface is then treated like a roof – with bitumen and that gravelly bitumen sheeting you see on flat roofs.


The green colour of the bitumen sheeting is merely to differentiate it from the ply.

Then Simon can have a thin coat of tennis court material if he chooses. The light boxes will be double-glazed and the deck will then be insulated and leak-proof.

That's the plan anyway!
