Latest Amels 80 superyacht completes technical launch

Year on year, the world’s leading shipyards raise the bar with superyachts that combine design, engineering and sheer scale – and 2025 was no different. Larger yachts are crossing the 100-metre threshold, highlighting the ongoing growth of the superyacht industry. Using exclusive BOATPro data, BOAT explores some of the largest launches by LOA from across the globe, starting with Germany and its grand addition…

Germany

Project Deep Blue

Builder: Lürssen
Length: 134.2m

The largest yacht to splash in German waters this year is the 134.2-metre Project Deep Blue. At 9,079GT, she is one of Lürssen's first projects to use the builder's new slipway at its facilities in Bremen, designed to handle heavier loads. Much of the yacht's details have been kept under wraps, with only her Winch Design exteriors revealed during her launch in summer 2025 and the subsequent sea trials in August 2025. Notable are her striking blue overhangs and five decks of amenities, featuring two pools, a helipad, a sloping mast and distinctive lower-deck glasswork.

The Netherlands

Project Tanzanite

Builder: Amels
Length: 120m

At 120 metres, Project Tanzanite is set to become the largest Dutch-built motor yacht in history, overtaking Amel’s 89-metre Here Comes The Sun by 31 metres. Built by Amels, with naval architecture by Damen Yachting and design by Espen Øino, who has worked on several high-profile Amels projects, she will be the largest 2025 launch from the Netherlands. Renderings of interiors by Francois Zuretti reveal a warm and contemporary aesthetic and curved furniture. The yacht will accommodate 22 guests across 11 cabins, served by a crew of 44. Spanning 6,083GT, power will come from diesel-electric engines and Azipod propulsion. According to the yard, the yacht is designed to operate with the “lowest levels of noise and vibration ever recorded on a yacht of this size". Project Tanzanite completed sea trials in October 2025 with final delivery slated for early 2026.

Italy

Amalya

Builder: Admiral – The Italian Sea Group
Length: 78m

At 78 metres, Amalya shares the flagship status within The Italian Sea Group’s (TISG) Admiral brand with Platinum, delivered last year, and marks Italy’s largest superyacht launch for 2025. She splashed at the beginning of 2025, and her Sinot Yacht Architecture and Design exteriors turned heads thanks to the aqua blue hull and array of amenities, including the six-metre swimming pool, dive area, gym and touch-and-go helipad. But perhaps one of the most talked-about aspects of the yacht is her “innovative” diesel-electric propulsion, variable-speed generators and Azipods, alongside the lithium-polymer batteries, which allow the yacht to anchor silently and emission-free. As TISG founder Giovanni Costantino puts it, she “blends innovation, elegance and profound respect for the environment".

Turkey

Simena

Builder: Ares Yachts
Length: 62m

Ares Yachts has claimed top spot for Turkey’s largest yacht launch with Simena, its new flagship sailing yacht measuring 62 metres LOA, including her bowsprit, set for delivery in 2026. Penned by Taka Yachts, the ketch draws inspiration from the “gentler age of sail", with a fully rigged bowsprit and trail board reminiscent of classic clippers. The name also pays homage to the maritime heritage of the ancient Turkish city of Simena. She comes in at the sweet spot of 499GT and made her debut at the Monaco Yacht Show 2025, where her features were showcased, including the Jacuzzi at the bow and Design Unlimited interiors. Accommodation is for 12 guests across five cabins, with an owner’s suite forward on the main deck with a private dressing room and lounge sofa. Equipped with an electronic remote-control system for hybrid propulsion, the yard says the system is “very user-friendly, highly accurate, advanced and flexible".

UAE

Al Hanem 2

Builder: Romeo Marine
Length: 54.4m

Al Hanem 2 is the first hull in Romeo Marine’s new Romeo 55 superyacht series to emerge from its sheds, with delivery scheduled for 2026. At 780GT, she offers above-average volume for her size, built with a steel hull and aluminium superstructure, courtesy of naval architecture from MASK Architects and Great Waters. The UAE-based yard describes her design as a “concept of light and space”, with floor-to-ceiling glass panels, high ceilings, indoor-outdoor flow and a skylight above the owner’s suite. Puline Exclusvie Interiors was responsible for the contemporary interiors that accommodate up to 14 guests. A sculptural spiral staircase, complete with a lift, links the decks. Crowning the yacht, her sundeck includes a pool, bar, barbecue and an upper-deck gym.

Poland

Miss Leen

Builder: Conrad
Length: 44.3m

Formerly known as Project Moonlight, Miss Leen is Poland’s largest superyacht launch for 2025, coming in at 44.3 metres. She is one of the three C144S models built by Conrad, a line the yard describes as “compellingly successful". Designed by Remond Langton Design with naval architecture by Diana Yacht Design, Miss Leen shares the same series as Ace (delivered in 2022 as Poland’s largest yacht at the time). Interiors are by Italian Nauta Design, accommodating 10 guests in five cabins and nine crew. Managed by Y.CO on behalf of the owner, the yacht was said to have been created to realise the vision of intimate family cruising while offering build quality and classic design.

Finland

BeCool

Builder: Nautor Swan
Length: 39m

The 39-metre BeCool sailing yacht has joined Nautor Swan’s fleet for 2025. As part of the Swan 128 series, it is the Finnish yard’s second-largest line after the Swan 131 Aristarchos, launched in 2006. Drawing on advancements from the Swan 108 and 88 platforms, BeCool made its debut at this year’s Monaco Yacht Show, sporting slender lines and a sculpted deckhouse, resulting in a performance-driven profile. Naval architecture was entrusted to German Frers, Swan’s long-term creative partner, and designed by Lucio Micheletti, focusing on lightness and functionality. Misa Poggi brings warm, tactile and modern aesthetics to the interiors, which accommodate eight guests. A generous sail plan of 715.6 square metres promises the renowned Swan performance. She can also house a 4.5-metre tender.

Taiwan

Ocean Alexander 37L

Builder: Ocean Alexander
Length: 37.2m

The latest 37L model of the Ocean Alexander 37L series was launched in Taiwan this year. One of nine Legend models, like the rest, she was designed inside and out in collaboration with Evan K. Marshall and can accommodate 10 guests in five cabins across 272 GT. A Jacuzzi complements the al fresco dining and lounging areas outside. Meanwhile, for power, two MAN engines result in a cruising speed of 18 knots.

Australia

SilverCat

Builder: SilverYachts
Length: 35.9m

Yet again, SilverYachts has claimed the trophy for Australia’s biggest launch this year with another SpaceCat model. The 35.9-metre multi-hulled yacht, SilverCat, is one of four SpaceCats, with Reduce launched as the largest last year. The series, designed by Espen Øino, has been hailed for its space and referred to as a “villa on water”, thanks to the 483GT volume and 13.3-metre beam. The 2022 SpaceCat model recently shone a spotlight on the design, taking a lead role in season three of HBO’s acclaimed social satire The White Lotus. SilverCat can accommodate 12 guests in five cabins. The four Volvo Penta engines deliver a cruising speed of 18 knots.

USA

Vagabond

Builder: Delta Marine
Length: 33.5m

The biggest project to be launched in America was the 33.5-metre Vagabond. The 33.5-metre yacht was built by Delta Marine and launched from its Seattle facility this year. A custom-crafted project shaped around the owner’s vision of cruising the wild stretches of Alaska, she is based on the yard’s new Delta 110 platform featuring a double-chine, semi-displacement hull designed for long-range efficiency and dependable in Pacific Northwestern waters. With a 7.3-metre beam, the yacht offers a family-focused layout. Inside her 299GT, accommodations are arranged for eight guests across three cabins, designed for extended time on board in more remote cruising. The yard, typically known for production yachts, notes it was “thrilled to work with the owner on their unique vision". At the owner’s request, Vagabond is also accompanied by a custom aluminium tender.

UK

Sunseeker 100 Yacht

Builder: Sunseeker
Length: 29.9m

The 29.9-metre Sunseeker 100 Yacht is the frontrunner for UK superyacht launches in 2025. Designed and built by the British yard, her 125GT offers accommodation for up to 10 guests across five staterooms, comprising a master on the main deck forward, as well as two doubles and two twins on the lower deck. She is packed full of amenities, including a Jacuzzi, sit-up bar and al fresco dining on the flybridge, plus a huge sunpad and seating on the foredeck.

Brazil

Builder: Azimut
