Like sister ship Keyaki, which was christened and launched earlier this year, Hamanasu will be among the first Japanese ferries to incorporate an energy-saving hull form consisting of an advanced bow and stern design. Mitsubishi Shipbuilding said propulsion resistance will be suppressed by an energy-saving roll-damping system combining an anti-roll tank and fin stabilisers.
Together, these features will enable a five per cent reduction in energy consumption compared to earlier vessels.
