The use of pumped raw water has been minimised. All cooling is done via box coolers which are sealed circuit radiators built in to the hull. Any failure of the cooling pipe work for engines, oil and hydraulic fluid cooling, or air conditioning, either internally or externally will not, therefore, lead to flooding within the boat. A further advantage of this system is that there are no raw water pumps to maintain, nor any sea strainers to clog.
In short the system is significantly more reliable and requires minimal maintenance.
