|Setting up prefrabicated aluminium bulkheads on the jig.||Adding wooden frames - see bilges midships, later to be a major problem with corrosion.|
|Adding more wooden frames - see widened keel/hog leading to the bow.

Napier Deltic Engines
The Napier Deltic diesel engine adapted for marine use (18-7A overhaul life 4000 hours) - the gearbox is actually a gear phasing unit for three crankshafts as this engine is configured like a Y with 3 banks of 6 pistons - an 18 cylinder two stroke diesel engine. Before cold starting the crank had to be turned 100 revolutions by hand to build up oil pressure and to ensure there was no water between the pistons which would cause the engine to hydraulic at start up, and bend connecting rods which might break at a later date. These engines were started by firing a cartridge or at sea by 'trailing in' the second engine.
