With the tanks installed I can now continue with the construction work in the aft compartment. This involves fixing the aft platform cross beam and building the transom steps

The two aluminium petrol tanks and the grey and black water waste tanks are installed in the stern compartments. To minimise the chance of corrosion the aluminium tanks are held off the tank floor by 8mm plastic strips fixed on the base with Sikaflex sealant. This should prevent them sitting in water. The stainless steel fixing bolts are packed with plastic washers to prevent galvanic effects. The petrol tanks are bolted to the main beam and the hull stingers. The waste tanks are held in a cradle to prevent lateral movement and strapped down to prevent vertical movement The aft platform framework has been fabricated and dry fitted. It can't be finally fixed as the aft platform beam needs to be removed to fit the tanks. The petrol tanks have arrived. The are custom made and pressure tested to meet CE standards. Each tank holds 250 litres and are made from 4.00mm marine grade aluminium (5083).
It will be easier to fit the petrol and waste tanks through the transom space so I can't finish the transoms yet. While waiting for the tanks I can get on with other jobs around the stern area. Tek tanks have made the plastic grey and black water tanks. They are custom made to fit the hull shape.
