The super schooner: The Rondal rig of the sister ship "Sea Eagle" has up to 3,500 square metres of cloth from Doyle Sails, which controls 34 Rondal winches - the strongest of which pull loads of up to 18 tonnes. Boat speeds of over 20 knots are logged even in moderate wind conditions.

Royal Huisman has started construction of the "Sea Eagle" sister ship with the project name TRIDENT 810 without an owner. Potential customers will therefore benefit from a significantly shorter construction time and could take delivery of the 81-metre schooner as early as 2028.

This has never happened before in the world of super yachts. An 81 metre long sailing yacht whose construction begins without an owner. This so-called spec build (editor's note: on speculation) is quite common for large motor yachts, but not yet for sailing yachts. Spec builds are usually laid on the basis of a successful model, which has the advantage that the design details are familiar and tried and tested. This saves the shipyard time, utilises the design and the buyer can take delivery of the new yacht in a much shorter time and set off on a voyage around the world.

TRIDENT 810 is the project name of the XXL three-master, which is being built in the shipyards in Vollenhove and modelled on the 81 metre long sister ship "Sea Eagle" is created. The design comes from the computers of Dykstra Naval Architects and Mark Whiteley Design.

Panamax dimensions and plenty of sailing performance

The 81 m long TRIDENT 810 will share the title of the world's largest aluminium sailing yacht with her sister ship "Sea Eagle" when she is launched in two and a half years. Her hull consists of a flexible, torsionally rigid aluminium structure, calculated using FEM and bonded with a motion-damping aerospace adhesive specially developed for this project. Three up to 61 metre high carbon masts with a total sail area of 3,552 m² (space-sheet) generate working loads of up to 125 tonnes.

TRIDENT 810 with powerful rig

Masts, booms and standing rigging were manufactured by Rondal; hydraulics and winches (tensile load up to 18 tonnes) allow all sails to be set simultaneously. Two 1,081-kilowatt Caterpillar diesels propel her to 22 knots, supported by battery and energy management systems. CFD simulations and wind tunnel tests optimised the rig, which can pass through the Panama Canal with Panamax dimensions (61 m). The angular hull with a width of 12.3 metres and a draught of six metres ensures high dimensional stability and low heeling. Sensors in the rig and rudder monitor real-time loads for structural and safety control.

Chartering on the sister ship

Interested parties who would like to find out whether TRIDENT 810 is right for them have been able to do so since last year with "Sea Eagle" on charter trip go. The exceptional sailor receives them for 550,000 euros per week current in FijiIn summer, the three-master cruises through Australian waters.
