The challenging brief from a client in the Emirates was to design a truly exceptional 15.2m (50ft) cruising catamaran that would sail faster than anything of its size to date – other than a pure racing multihull.

As the project developed A65 became a 50ft catamaran with 19.8m (65ft) hulls – a move that Irens believes to be a cost-effective way to improve boat speed, safety seaworthiness and comfort.

Built by Abu Dhabi Mar in the UAE, the full carbon fibre construction has been part of a rigorous weight saving exercise with the addition of a rotating carbon wing mast and carbon rigging.
