The superyacht industry has seen a new audacious concept landing in recent days: named after a Gaelic water goddess, the 175-metre-long superyacht concept ACIONNA, created by British yacht designer Andy Waugh, would be powered by hydrogen if built. Inspired by Norwegian ferries and cruise liners, reading as much as he could about the new propulsion method before designing this striking project, Andy Waugh has created in ACIONNA a world-cruising superyacht intended to challenge the preconception held by many that larger yachts are homogenous and conventional. Her avant-garde styling is visible from every angle, which is exaggerated by her elegant scale. Waugh describes ACIONNA as an utterly unique superyacht concept with elegant proportions. The interior space would be voluminous and potentially include a full-size squash court, helicopter hanger and a 20m indoor pool. Arranged over eight decks, a showcase double-height main saloon would be clad in panoramic curved glass overlooking the main aft deck pool. This area of the design leading down to the swimming platform is unusual as it comprises of a central "island" of communal areas completely surrounded by the pool and accessed via a tunnel aft and a bridge forward. The pool continuously flows down the sloped transom and into a lower pool of the swim platform. Keenly aware of the environmental implications of superyachts, Waugh imagines that ACIONNA will be powered by hydrogen using a similar system currently being trialled in cruise ships and ferries. If the power used to manufacture the hydrogen is purchased from renewable energy sources, then the yacht could be considered "zero impact" on the environment. "Hydrogen propulsion currently makes the most sense with larger vessels requiring long-range capability." says Waugh. "However, at present there are only a few marine hydrogen facilities in the planning stage. Until vessels like this one are built, there will be no way to increase demand for hydrogen, thereby breaking the chicken and egg stalemate of supply and demand. Building hydrogen facilities is not economic without the demand from numerous hydrogen powered vessels." We look forward to learning more about the concept and the hydrogen propulsion system which could herald an important revolution in our industry.
