The Leopard 53PC is the most successful power catamaran built by Robertson & Caine. Unlike the builder’s earlier powercats, 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 an extremely well spec'd from the factory with noteworthy features including:
Bow thruster
Upgraded RayMarine Axiom electronics, including dual screens at both the flybridge helm and lower helm
12KW transformer for global shore power
Glendenning shore power reel
Fresh water heads
Washer/Dryer combo unit
Dishwasher
Flybridge wet-bar w/infrared grill, ice maker, and refrigerator
Wine fridge
Hydraulic platform
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 53PC currently on the market with over $2,000,000 invested in the program. Some of those well thought out upgrades include:
Flexiteak added to the cockpit and flybridge
2800 watts of solar on the hardtop
Custom 48v electrical system that allows the entire boat to run "Silent"
28.8 KW of top of the line Victron Lithium batteries
Victron Quatro 15KW inverter
Victron Quatro 10 KW inverter
High output Rainmain water maker
Oil change system for both Yanmar diesels
Sonic Hull Antifouling System
Custom cabinetry throughout the boat
Custom cockpit island
Custom boarding steps for either port or starboard side boarding gates
Owner's stateroom berth expanded for king-size bed
If you are in the market for either a new Leopard 53 Power Cat, or pre-owned Leopard 53 Power Cat, Althea is worth considering.
The Leopard 53 Powercat stands as the largest and most advanced vessel in the Leopard family — a flagship powercat that redefines what luxury cruising can be. Named the 2020 Multihull of the Year, the Leopard 53 has earned international recognition as a leader in its class, delivering the perfect balance of performance, comfort, and innovation.
Sea-trialed off the coast of South Africa, this fourth-generation powercat offers remarkable ease of ownership and up to 50% greater fuel efficiency than comparable monohull motor yachts. A bold evolution of the Leopard 51, the Leopard 53 has been reimagined from the hull up to provide greater speed, enhanced livability, and an elevated onboard experience.
Built by renowned yacht builder Robertson & Caine and designed by award-winning naval architects Simonis Voogd, the Leopard 53 marries rugged cruising capability with refined luxury. With no compromise between adventure and comfort, this vessel delivers unprecedented space, stability, and efficiency for long-range cruising in style.
