The America’s Cup World Series has seen its fair share of innovative sailing yachts, but none have captured the imagination quite like the AC45F. This sleek, high-tech catamaran is a testament to the cutting-edge design and engineering that defines modern sailing. Here, we delve into the fascinating world of the AC45F, exploring its design, specifications, and the remarkable performance it delivers.
Design and Construction
Mike Drummond and Oracle Racing conceived the AC45F as a one-design wingsail catamaran specifically for the America’s Cup World Series. Built by Core Builders Composites in New Zealand, this yacht is a masterpiece of composite construction, featuring a honeycomb core and carbon fiber sandwich. The AC45F stands at an impressive 44 feet 1 inch in length and 22 feet 7 inches in beam, with a dry weight of 3,640 pounds[2].
Hydrofoiling Capability
One of the most significant advancements in the AC45F is its hydrofoiling capability. Introduced in 2015, this feature allows the yacht to lift its hull out of the water, reducing drag and significantly increasing speed. The AC45F can reach peak speeds of 37 knots, making it one of the fastest sailing yachts in the world. This remarkable speed is achieved through the use of retractable foils, which enable the boat to rise above the waterline, creating a hydrodynamic advantage that propels it forward with incredible efficiency[2][4].
Sail Inventory and Rigging
The AC45F is equipped with a large wingsail element, measuring 20 meters in length and 83.5 square meters in area. This massive sail is complemented by a jib and gennaker, providing additional lift and stability. The sail inventory is provided by North Sails, ensuring top-notch performance and durability. The rigging system includes state-of-the-art components such as Harken Grand Prix racing winches, Southern Spars EC6 standing rigging, Spinlock power clutches, and Gottfried Maffioli running rigging with Technora covers. These high-quality components ensure that every aspect of the yacht’s performance is optimized[5].
Performance and Handling
The AC45F is designed to be highly maneuverable and responsive. It features two conventional leeboards (daggerboards) and two balanced spade rudders, which provide exceptional control and stability. The boat’s design allows it to foil on the leeward foil, while the windward foil is raised to enhance the righting moment, helping to balance the yacht. This sophisticated system enables the AC45F to easily perform complex maneuvers, making it a joy to sail for experienced sailors and a challenge for newcomers[2][4].
Crew and Operations
The AC45F requires a skilled crew of five sailors, plus one guest. The crew must be highly coordinated to maximize the yacht’s performance. The boat comes with two containers, containing all the necessary equipment for launching and maintaining the yacht overnight on a mooring. This comprehensive package ensures that the AC45F is always ready to sail, with plenty of spare parts and accessories available[5].
Historical Context
The AC45F was first introduced in 2012, and it quickly became a star of the America’s Cup World Series. Its debut marked a significant shift in sailing technology, as it was one of the first yachts to incorporate hydrofoiling into its design. The AC45F has since become synonymous with high-performance sailing, pushing the boundaries of what is possible on the water. Its success has inspired a new generation of sailors and yacht designers, driving innovation in the world of sailing.
Conclusion
The AC45F is more than just a sailing yacht; it is a testament to human ingenuity and the relentless pursuit of excellence. Its advanced design, cutting-edge technology, and exceptional performance make it a marvel of modern sailing. Whether you are an experienced sailor or simply someone who appreciates the beauty of high-performance sailing, the AC45F is a yacht that commands respect and inspires awe. As we continue to push the boundaries of what is possible on the water, the AC45F remains at the forefront of this exciting journey, a true icon in the world of sailing.
