Cabinet Rebuild

A single-door locker beside the fridge and freezer, beneath the electrical cabinet, had become a convenient place for miscellaneous items. We decided to remove the side panel and convert the space into a dedicated liquor cabinet.

All hinges and latches were designed specifically for the installation and 3D printed at home. The cabinet doors were custom-made from tinted glass, providing visibility while helping protect the contents and reduce the risk of accidental scratching.

Custom Long-Range Fuel Tank

Atlas Tanks built this custom 280-litre tank to our specifications. We required additional strength across the top surface, so the internal baffles were specially cut and welded to provide greater structural support.

To maximise the available storage space around the tank, we specified all inspection, filling and connection openings on the top surface.

This allowed the tank to fit efficiently in the available space while keeping access points accessible for maintenance. It is positioned under our rear aft external saloon seat.

A separate pump was installed to allow diesel pumping in and out of the tank. This reverse-cycle system (with shutoff valves) permits fuel polishing if required. The diesel then goes to the Starboard Fuel Tank only.

Engines are a critical safety system. Whether you're manoeuvring through a narrow reef pass or motoring into strong headwinds, engine reliability can make the difference between a minor inconvenience and a serious problem.

Routine inspections often reveal small problems such as a weeping coolant hose, loose hose clamp, worn drive belt, contaminated fuel filter or slight oil leak before they develop into costly failures.

Yanmar places strong emphasis on daily inspections and scheduled maintenance, stating that regular servicing helps prevent breakdowns, reduces running costs, maintains safety and performance, and extends engine life.

Over thousands of engine hours, these simple maintenance tasks can reduce operating costs while increasing confidence that your engines will start when you need them most.

Yanmar notes that neglected filters, lubrication systems and cooling components can reduce combustion efficiency, impair engine performance and accelerate component wear. BE PROACTIVE.
