The Leopard 53PC is the most successful power catamaran built by Robertson & Caine. Unlike the builder’s earlier power cats, which were based on sailing platforms, this is their first design in nearly 20 years developed from the beginning to be a motor yacht. The 2025 Leopard 53 Althea is without a doubt the best example of a Leopard 53 PC currently on the market.
She is extremely well specified from the factory, with numerous noteworthy features.
Althea was further improved with an extensive list of aftermarket upgrades with zero expense spared. She is without a doubt the most well-equipped Leopard 53 PC currently on the market, with over $2,000,000 invested in the program.
If you are in the market for either a new Leopard 53 Power Cat or a pre-owned Leopard 53 Power Cat, Althea is worth considering.
