YACHTSMEN INTERNATIONAL is proud to present this exceptional 2017 78’ LAGOON CATAMARAN Galaxy Big Sister’ or ‘GBS’ which is arguably the highest specified Lagoon SEVENTY8 ever ordered and is now offered for sale

The Lagoon SEVENTY 8 is the new flagship of this magnificent brand.  This Lagoon SEVENTY8 was commissioned by a very experienced Australian family who have previously commissioned one of the world’s most successful 56M Super Yachts.  With a staggering 4000nm range and carrying 8,500L of fuel, this Catamaran is perfect for stable, safe and luxurious bluewater exploration. A fully crewed and professionally managed vessel from launch, GBS has had no expense spared in her commissioning and ongoing upgrades and management.

Production took place at CNB Lagoon, Bordeaux, the world leader in catamaran production with moulding and completion taking place in the new purpose-built facility. In October 2017 she was pre-commissioned in France before final commissioning took place and she was handed over in Sydney, Australia in January 2018.

From initial order to build, custom installations, commissioning and aftersales, TMG provided a consistent solution for her owner and an ever-available touchpoint for the full-time captain and crew. Allowing for the owners to get on the with serious business of fun, adventure and entertainment.

A special vessel deserves a special owner. GBS was commissioned by an Australian business magnate, a seasoned owner of superyachts around the world. Her new owner can be confident that there has been no expense spared in the preparation, and equipment specification onboard.

The challenge is to find another vessel in production today that delivers;
o    4000+ nautical miles in range.
o    19knots top speed.
o    Comparable in area and volume to many 35M monohulls.

With the surge in popularity for power catamarans and the subsequent levels of global demand, the 78MY production in Bordeaux is now sold out until the end of 2021. With only 4 others on the water today, this represents an opportunity to purchase a unique and in-demand product, available now and for an approximate saving of 2million AUD on a like for like replacement.
