SEA EAGLE II Integrated Sailing System

Just launched in Amsterdam after her sea trials were completed in the North Sea, SEA EAGLE II is now on her way to explore the seven seas. With her 81mtr LOA, she is the largest aluminum sailing yacht in the world. SEA EAGLE II, the impressive and already iconic superyacht, was built by Rondal’s sister company Royal Huisman, and designed by Dykstra Naval Architects and Mark Whiteley Design. Her three carbon composite equally tall masts are equipped with advanced Rondal furling booms, which are styled and shaped to match the design of the yacht. Additionally, the aft and main mast are equipped with staysails for reaching courses.

One piece mast & Out of Autoclave manufacturing

Rondal is the only company in the world capable of building a 60+mtr superyacht sailing mast in one piece. How do they do that: Rondal was an early adopter of the innovative OOA (Out of Autoclave) method and has since, for decades now, mastered the art. This allows Rondal to produce without the limitations and expenses of an autoclave. Many mast builders still stick (or shall we say ‘are stuck’?) to conventional and inept autoclave manufacturing at high costs, forcing themselves to build masts in multiple sections which subsequently have to be bolted together. This method doesn’t keep things ‘simple’, lean or elegant.

Load sensing rudder

Traditionally, rudder stocks of ships and very large yachts are built using stainless steel / SAF metal alloy. Because of increasingly higher performance demands, rudder blades designs tend to be thinner. This, of course, poses a challenge in terms of strength as high forces can build up when the rudder is subjected to high loads when sailing. To cope with these enormous forces while maintaining a high performance design. A better – stronger material was chosen; carbon UD fibre composite laminates.
