McConaghy GT86 Power Catamaran Launch
When McConaghy launched a new model, it always creates a stir. They have a talent for creating new designs to turn heads and their latest power cat is no different. Take a look at this beauty. It’s the first of their Gran Turismo Series.
McConaghy Boats has launched the first GT86, a bespoke 25.54 m (83 ft 9 in) power catamaran. She now moves into sea trials and systems commissioning ahead of shipment to her owner. With a narrower beam than most, she has a big open saloon, free of bulkheads and partitions. She is built for fast passage making and offshore sprints.
The GT86 pairs twin Volvo Penta IPS 1350 pod drives with 15,000 litres of fuel. McConaghy reports a top speed of around 28 knots and a range above 3,000 nautical miles. At roughly 50 tonnes and 9.24 m wide, she is faster and slimmer than most power cats of her length.
The yard describes her as two years in the making. She carries a new integrated vessel control system, which McConaghy plans to roll out across selected builds.

Layout and design
The GT86 keeps guest life on the main deck. The saloon opens onto an aft terrace, and a large foredeck gives a second place to relax at anchor. Twin sets of steps lead down to the water.
The owner’s suite and several guest cabins sit below deck. The accommodation set up is flexible, one option being four cabins plus one crew cabin.
The yachts boasts a sports coupe profile with a long, open saloon. The narrow 9.24 m beam suits a boat built for speed rather than maximum volume. Standing headroom is a comfortable 2m.
Performance, range and systems
Twin Volvo Penta IPS 1350 drives give a top speed of about 28 knots. The 15,000 L fuel capacity supports a range above 3,000 nm.
The GT86 debuts a new integrated vessel control system. Owners reach all onboard systems through one common interface. The hull is composite, built on the yard’s 50 years of experience in racing yachts, America’s Cup work and cruising boats.
How the GT86 compares
The GT86 is longer than every rival below and quicker than any of them in standard form. It gives up beam and, most likely, interior volume to get there.
Verdict
The GT86 is a fast, long-range flagship for an owner who values speed and range and is a design that will turn heads at the marina.
The first hull is heading for a private owner. Further updates, photography and footage will follow as the range develops.
