For those who dream of combining luxury, adventure, and an off-the-grid lifestyle, living on a catamaran is the ultimate fantasy. In a detailed exploration of a family’s home on the water, we step aboard Emma James, a 52-foot aluminum catamaran designed by an Australian naval architect, Lo Crather. Built in 2005 and extensively refitted, this vessel is not just a boat - it’s a fully functional floating home.
Whether you’re considering an extended marine adventure or simply intrigued by the concept of living aboard, this comprehensive guide offers insights into the design, features, and everyday practicality of such a lifestyle.
The Emma James: A Unique and Custom-Built Vessel
The Emma James is far from your average catamaran. With a design focused on durability, performance, and functionality, this aluminum vessel boasts unique features that set it apart. Here are some highlights:
Aluminum Construction: The boat’s aluminum hull ensures robustness and longevity. Despite being built in 2005, the vessel remains in impeccable condition, with no need for major structural replacements.
Dagger Boards Instead of Mini Keels: Unlike many catamarans with fixed keels, Emma James uses adjustable dagger boards. These boards are winched up and down, allowing for better control of draft and performance in varying water depths.
Bow Flare: A standout feature is the pronounced bow flare, typical of Lo Crather’s designs. This not only enhances the vessel’s stability but also gives it a visually striking profile.
Refitted Sugar Scoops: During a 2004 refit, the sugar scoops (the steps leading into the water) were extended, improving the boat’s swim platform, tender accessibility, and overall speed and performance.
Exterior Features: Where Function Meets Family
Designed with both adventure and family safety in mind, the exterior of Emma James is a blend of practicality and comfort.
Safety and Accessibility
The catamaran is fully equipped for a four-year-old child, featuring:
Child Netting: Protective netting installed around the boat ensures safety for younger passengers.
Solid Lifelines and Handrails: These provide added security while moving around the deck, especially during rough seas.
Solar Energy and Connectivity
Energy independence plays a significant role in the family’s lifestyle:
Solar Panels and Wind Generators: The boat is outfitted with multiple solar panels and two wind generators, ensuring sufficient power for extended off-grid living.
Starlink Satellite Internet: Connectivity is no issue, thanks to a Starlink setup that allows high-speed internet even in remote locations.
Thoughtful Modifications
During their refit, the family extended the back deck roof and added canvas coverings. These modifications transformed the previously exposed deck into a shaded, multipurpose space ideal for relaxing, dining, or escaping the sun after a day of exploration.
Interior Layout: Smart, Functional, and Cozy
Despite its compact size, the interior of Emma James is designed for maximum utility, making it feel like a well-equipped home on the sea.
The Saloon: A Centralized Living Space
The saloon serves as the heart of the boat’s interior:
Panoramic Visibility: Large windows provide 360-degree views, ensuring excellent visibility during long passages or while anchored.
Multi-Purpose Table: A world map and family photo collage on the table add a personal touch, while its size makes it suitable for dining, work, or games.
The Galley: Compact but Efficient
The galley is optimized for both culinary creativity and energy efficiency:
Three Sinks: Separate sinks for washing, cleaning, and drying maximize water conservation.
Dual Cooking Options: Both a gas stove and an induction cooktop offer flexibility depending on available power.
Ventilated Storage: Mesh cabinet doors prevent mold growth in humid climates, making them ideal for storing dry goods.
Bedrooms: Comfortable and Functional
Each cabin is thoughtfully designed for privacy and practicality:
Queen-Sized Beds: Spacious sleeping arrangements cater to both the family and their guests.
Creative Storage: Closets and under-bed compartments maximize storage without cluttering the living space.
The master cabin’s high ceilings allow one person to climb over their sleeping partner without disturbance - a small but significant detail that enhances comfort.
Bathrooms: A Balance of Utility and Luxury
The boat’s bathrooms offer thoughtful features:
Separate Shower and Toilet: This design keeps the toilet and toilet paper dry during showers, an often-overlooked convenience.
A "Shub" Setup: The shower floor doubles as a mini bathtub, perfect for their young daughter.
Sailing and Navigation: Designed for Performance
The Emma James is not just a home - it’s a high-performing vessel built for serious sailing.
Winches and Rigging
The cockpit features five winches, with additional winches on the mast, allowing for efficient sail handling. Tasks like furling sails or adjusting the dagger boards are manageable with one or two people, emphasizing the boat’s ease of operation.
Navigation Hub
The navigation station is equipped with advanced tools for long-distance sailing:
Customizable Screen Setup: A large, tiltable display makes chart plotting and monitoring effortless.
Accessible Electrical Systems: The station doubles as an entry point to the boat’s electrical systems, ensuring quick access for troubleshooting or upgrades.
Redundancies for Safety and Comfort
The family prioritizes redundancy in critical systems. For example, they have multiple freshwater options, including a manual pump, as well as a backup fridge/freezer for extended trips.
Life as a Family Onboard
Living aboard a boat with a young child comes with unique challenges and rewards. The family has incorporated practical solutions to make life easier and safer:
Laundry Solutions: A compact but efficient washing machine and multi-purpose tubs streamline laundry and serve as makeshift swimming pools for their daughter.
Entertainment: A mounted TV, books, and a dedicated area for Charlie’s educational materials ensure that the family’s lifestyle remains well-rounded.
Car Seat and Printer: Even without a car or permanent home, small items like a car seat (for taxis or courtesy cars) and a printer prove invaluable for their mobile lifestyle.
A Special Space for Charlie
Charlie, their four-year-old daughter, has her own room with a queen-sized bed, storage, and space for play. Her room even houses one of the catamaran’s engines, which she affectionately calls "her engine."
Key Takeaways
Customization Matters: From extending the back deck roof to adding safety netting, personalized modifications make life aboard both comfortable and functional.
Energy Independence: Solar panels, wind generators, and Starlink ensure off-grid living without sacrificing modern conveniences.
Safety First: Child-proof features like netting, solid lifelines, and lockable gates make the boat a secure environment for young children.
Redundancy is Key: Backup systems for water, electricity, cooking, and refrigeration reduce the risks of long-term cruising.
Efficient Space Utilization: Clever storage solutions, dual-purpose areas, and ventilated cabinets maximize the boat’s square footage.
Family-Centric Design: Features like a mini bathtub, educational areas, and entertainment options cater to the needs of all family members.
Performance Meets Comfort: With its adjustable dagger boards, winches, and helm station, the Emma James performs well at sea without compromising on comfort.
Conclusion
The Emma James is a testament to how a catamaran can be transformed into a luxurious, functional home on the water. From its innovative design to its family-focused modifications, the vessel offers a glimpse into the possibilities of a life less ordinary. For those considering a similar lifestyle or simply curious about life at sea, this aluminum catamaran serves as both inspiration and a practical blueprint.
Living aboard may not be for everyone, but for this family, it’s a perfect blend of adventure, freedom, and personalized luxury. Could this lifestyle be right for you? Only the open water knows.
