Better thermal insulation

Stepping aboard a superyacht in build is like entering a space station. Behind all the panels will be silver-backed insulation, often up to half a metre thick and made up of alternating layers of density. Running over these will be a maze of wires and pipes, with many of the latter insulated as well.

Insulation drastically reduces the flow of both heat and cold into, through, and out of the hull. The manufacturers of aluminium-faced thermal insulation claim that some types can stop up to 97% of radiant heat. This prevents the yacht getting too hot in the tropics (even when the hull has been painted the classy dark blue or black colours) or too cold in the Arctic. This takes a great deal of pressure off the heating, ventilation and air-conditioning (HVAC) systems so less energy is needed to maintain a comfortable temperature inside. This in turn eases the demands on the generators, and so reduces noise and smoke, and saves fuel.

Insulation also helps prevent condensation, with the HVAC system providing a dehumidifying function as it circulates the air.
