Swan 100-204
December 2007
Pictured above is the Rextroth hydraulic main unit. This unit is located on the forward bulkhead of the engine room. The large stainless tank is the hydraulic oil reservoir and on top are two 5 kW DC pumps. In addition to the two electric pumps there are PTOs (power take offs) on each generator. The engine drawings show a PTO on the main engine also, however the specs list PTOs only on the generators. On the Swan 77 all of the valves for the various hydralic units were located on top of the reservoir. This boat utilizes a ring system in which a large stainless pipe pressureized with hydraulic oil circulates about the entire yacht. The valves for the individual hydraulic units are located on this "ring" near the unit itself. Instead of dozens of hydraulic hose running from the main unit, there is only one large pipe plus a return.
The three black tanks are part of the Condaria central air conditioning system, located on the port side of the engine room. The white box to the left is the control box for the Condaria A/C system. Behind the Condaria tanks (and barely visible) is a stainless steel tank that is split into two for clean and waste oil. Since the generators run almost continuously, oil changes are required often. The blue valves below the Condaria system are part of the oil manifold -- waste oil can be pumped from engine and generators into waste tank and replenished from clean tank easily. Clean tank can be filled from deck and waste tank can be emptied from deck.
Above is the HEM water maker, capable of producing 5,000 liters of freash water a day. This unit is located on the forward bulkhead just to starboard of the Rexroth hydraulic unit.
Outboard on the starboard side of the engine room is the HEM water maker sand filter. To the left is the control panel for the hydraulics and to the right is the main relay cabinet.
Above is the main DC electrical panel. This is where the power comes in from the batteries and the majority of the yacht's electrical components get their power.
Outside and aft of the engine room is the diesel fuel manifold.
The next series of photos show the deck being installed on the hull.
NOW THOSE ARE SOME KEEL BOLTS!
