This drawing mainly shows the tank location. The engine room is located just after mid ships. The fish hold before the main fuel tanks.
We can currently take about 130+ tons in fuel oil (over 34.000 gallons). Filling it up is well beyond my VISA card limit!
We plan to bring this down to about 90 tons, which would still give us an economy range of about 10.000 miles, enought to make it back to Cook's bay (Tahiti) and back again without refueling.
The fuel tanks in the back will be partly converted to storage space and put in use as fuel oil day tank and and lubrication oil storage.
