Named after a Gaelic water goddess, yacht designer Andy Waugh's new concept, Acionna, would be powered by hydrogen if built. The designer tells that he was inspired by Norwegian ferries and cruise liners, reading as much as he could about the new propulsion method before designing Acionna.

At 175m in length, Waugh says that Acionna would be an ultimate world cruising superyacht that challenges the preconceptions about larger yachts, often considered homogenous and conventional.

Keenly aware of the environmental implications of superyachts, Waugh imagines that the concept 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 the yacht could be considered ‘zero impact’.

Especially unique in Acionna's design is her stern pool comprising of a central ‘island’ of communal areas completely surrounded by the pool and accessed via a tunnel aft and a bridge forward. The pool flows constantly down the sloped transom, which can be used as a slide, and into a lower pool on the swim platform.
