Netherlands-based yacht builders Holterman Shipyard have unveiled a new in-build Xtreme 78 Flybridge yacht, Boost to its Xtreme series. The 23.9-metre yacht focuses on warm-weather cruising and is due for delivery in early 2024.
The Xtreme 78 Flybridge yacht Boost is an evolution of Holterman Shipyard’s Xtreme 78 Sport model and features the same sleek exterior styling. She has been designed with a sophisticated low profile for cruising Dutch canals and northern waters, alongside a voluminous hull. 
With exterior design by long-term collaborator Bernd Weel, she features a striking profile, with the addition of a flybridge for alfresco summer dining. This yacht marks the fifth order in the Xtreme series since the launch of the award-winning 32.65-metre Xtreme 105 yacht Lady Fleur in 2022.
“Building on the success of the Xtreme 105, this philosophy has been seamlessly carried over to our subsequent models, including the Xtreme 54, 60, 78 Sport, and now the Xtreme 78 Flybridge. Each of these smaller models has been meticulously designed and built to ensure they satisfy all the needs and desires of a superyacht experience in a more manageable size,” explained Holterman Shipyard’s sales and operational manager, Julian van Santen.
Boost can comfortably sleep up to eight guests, across a four stateroom configuration consisting of a full-beam master amidships, two twin VIPs and a guest stateroom forward, with interior design from Kitty van der Kamp.
“What stands out aboard the Xtreme yachts is the interior is crafted from solid wood, combined with natural stone or composite materials in the kitchen and bathrooms. We offer a lot of freedom in material choices, including wall coverings, wood types, door hardware, bathroom fittings, and more. This ensures that each customer truly builds their own yacht, creating a unique and comfortable environment that feels like home,” Van Santen added.
The Xtreme 78 Flybridge is designed to anchor in the French Riviera without restrictions and includes features such as a helm station, wet bar, alfresco dining and multiple sunpad areas for the warmer weather conditions. 
“The area has been designed for lounging, and has a lot of features to enjoy time gathered with family and friends; including sunbathing, having dinner or drinks alongside the bar, and controlling the yacht from the fully-equipped and well-designed helm station,” commented Bernd Weel.
“One of the features I really love are her chaises longues flanking the helm station. These are perfect for lounging when your partner is controlling the yacht during a cruise and give a very social connection. The captain doesn’t have to be alone, and still enjoys a free and unobstructed view forward.”
The flybridge of Boost boasts an electrically-operated sliding roof, allowing up to 12 guests to enjoy the bar while soaking up the sun. She has also been adapted to meet the needs of her owner who enjoys a place to take in peaceful contemplation of the ocean. 
“We added seating on the stern; a solid bench on the hatch directly located at the swim platform where the owner enjoys sitting, and being very close to the water. Another feature they really liked is the bar on the fly deck. It is covered by a hardtop with a sliding canvas roof and is the perfect place to enjoy a drink with friends,” explained Bernd Weel.
The Xtreme 78 Flybridge is also equipped with a hydraulically-operated aluminium platform at the stern, capable of lifting a tender of up to 1,000kg, watermaker. As well as this, a pair of wings fold from the fly deck, arching out over the walk-around main deck to port and starboard and emphasising the yacht’s 6.18-metre beam.
“We added these because of the taller flybridge superstructure. It was needed to regain some balance and to give a stronger appearance. They are mounted in a hanging way from the superstructure, therefore ‘floating’ on the bulwark,” said Weel.
In terms of performance, the Xtreme 78 Flybridge yacht is powered by twin Volvo Penta IPS 1350 engines, providing her with a cruising speed of 20 knots and a top speed of 26 knots, with a range of 450 nautical miles at 13 knots. 
“The design has struck a chord because it incorporates both sturdiness and elegance,” concluded Holterman Shipyards’ general director Herman Timmerman. “Based on a proven platform, all kinds of wishes are up for discussion, from the exterior design to the interior and the choice of engines. A hybrid option is on the table too, and we love to innovate with clients by involving them in every step of the process. The Xtreme philosophy is attracting people who appreciate our down-to-earth approach and understand that creating something new takes time, effort and imagination.”
