SeaDream Yacht Club has unveiled plans for SeaDream III, a new 151-metre hybrid-electric yacht scheduled to enter service in July 2029 as the company marks its 25th anniversary.
The new vessel will expand SeaDream’s operation beyond the Mediterranean and Caribbean, with an ambitious inaugural programme covering six continents, 74 countries and 392 ports during its first 26 months.
SeaDream III is due to welcome guests for the first time on 10th July 2029, sailing from Hong Kong to Tokyo.
Founder Atle Brynestad announced the project as he reflected on SeaDream’s first quarter-century, which has taken the company through the aftermath of the 11th September attacks, the global financial crisis and the Covid-19 pandemic.
SeaDream III will be considerably larger than the company’s two existing yachts, measuring 151 metres long and 21.8 metres wide. SeaDream says the additional size is intended to give the vessel the capability to operate a much broader range of worldwide itineraries while retaining the small-ship approach of SeaDream I and SeaDream II.
The company has stated that SeaDream III will carry 230 guests and approximately 200 crew, providing a near one-to-one crew-to-guest ratio.
A New Hybrid-Electric Yacht
SeaDream III will use hybrid-electric propulsion supported by a large battery installation. According to Brynestad, the system will allow the yacht to approach some destinations with its engines switched off, reducing noise during arrival.
The vessel will also feature three marinas designed to support water sports, extending one of the features associated with SeaDream’s existing yachts.
Crew facilities are receiving particular attention in the new design. Crew members are set to have private cabins, while dedicated facilities will include professional gyms and a separate sun deck with a jacuzzi.
Construction will take place at China Merchants Cruise Shipbuilding in China, with European engineering companies and suppliers of technical equipment and other systems also involved in the project.
“We have extremely high standards for quality, craftsmanship, technology, different solutions and environmental performances,” Brynestad said.
SeaDream has not yet disclosed full details of the yacht’s accommodation, public spaces, dining facilities or other onboard amenities, with further information expected as construction progresses.
The vessel’s size represents a substantial change for the brand, although Brynestad said the intention is to retain the operating philosophy established aboard SeaDream I and SeaDream II.
That includes an informal onboard environment without formal nights, restaurant reservations or fixed approaches to dining. Guests will continue to be able to eat indoors or outside, while the company intends to maintain its emphasis on personalised service and flexible dining.
Brynestad described the next stage of the company’s development as “global yachting”, reflecting the much wider geographical reach planned for SeaDream III.
During its first 26 months of operation, the yacht is planned to visit 392 ports across 74 countries on six continents. Its itineraries will also provide access to 206 UNESCO World Heritage destinations, according to the company.
The vessel is being designed to reach smaller ports, remote islands and coastlines that are inaccessible or unsuitable for larger cruise ships.
SeaDream I And II To Remain In Service
The arrival of SeaDream III will expand rather than replace SeaDream Yacht Club’s existing fleet.
SeaDream has confirmed that SeaDream I and SeaDream II will continue operating in the Mediterranean and Caribbean after the new yacht enters service. Brynestad said the two original vessels are expected to remain with the company for “many, many years”.
The expansion comes as SeaDream celebrates 25 years since its establishment in September 2001.
Brynestad, who previously founded Seabourn Cruise Line in 1988 and served as chairman of Cunard Line, recalled that SeaDream had been operating for only 11 days when the terrorist attacks of 11th September 2001 severely disrupted travel.
The company subsequently navigated the financial crisis of 2008 and 2009 before facing the unprecedented shutdown of the global cruise industry during the Covid-19 pandemic.
In summer 2020, SeaDream I and SeaDream II continued operating when most passenger shipping around the world had stopped. Brynestad cited the period as one of several major challenges the company and its employees have faced during its first 25 years.
Staff retention was a major theme of his anniversary message. SeaDream awards employees a diamond on a company service pin for every five years they have worked with the business, and Brynestad said he has personally presented more than 170 diamonds, pins and diplomas during 2026. Some employees now have five diamonds after working with SeaDream since its earliest days.
The company has also developed a significant full-yacht charter business over the past quarter-century. More than 500 complete yacht charters have taken place for occasions including weddings, birthdays, anniversaries and family gatherings, as well as corporate events.
SeaDream’s long-standing guests were also highlighted during the anniversary. Some have accumulated between 50 and more than 200 days aboard the company’s vessels, while Brynestad said two guests have sailed for 1,400 days with SeaDream and have another 47 voyages booked.
SeaDream III will now form the centrepiece of the company’s next phase of expansion. Further details covering its design, technology, onboard facilities, cuisine and destination programme are expected to be released as the project advances towards its scheduled July 2029 debut.
