Ed Joy Design has been working with an Australian sailor to develop a safe, beautiful and comfortable portable home for him and his family. Here are the results thus far.
Most of our clients who intend to complete long offshore passages have had us design the largest boat they feel comfortable running themselves without professional assistance. The resulting boat is usually a modern design between 55 and 65 feet long, of which the Lyman Morse 55 and Visions of Johanna are good examples.
Tarni’s owner is more ambitious. He has experience operating larger yachts and knows that there is no substitute for size when it comes to security and comfort offshore. A large yacht also allows for installation of reliable commercial grade equipment with ample room to maintain each item, as well as adequate fuel capacity for long Pacific voyages. Indeed, during the many iterations of the development of the general arrangement, the most common comment we received from him was, "That's terrific, but can we make the engine room bigger?" The answer was always, “Yes, but we’ll need to enlarge the boat along with it.” After we had reached the size threshold above which the yacht would be subject to MCA LY2 charter regulations, he spent some time on a seawall near his home observing the waves offshore during a gale, and decided to eschew chartering altogether and selected the final 90 foot overall length.
He is also an admirer of traditional lines, so the hull is a modern interpretation of classic shapes, with moderate freeboard, sweeping sheer and graceful overhangs. There is a slight hollow in the waterlines forward and the stern is broad and powerful for speed and stability. A centerboard emerges from a long fin keel for upwind performance, allowing for a board-up draft of only 7'-6".
Since Tarni will be lived aboard for long periods of time, the satin finished African sapele and white interior is laid out to make life on the boat as similar as possible to life ashore. On shore, the social center of the family home is the kitchen, where conversations are enhanced by sumptuous aromas arising from dishes being expertly prepared by the owner’s restaurateur wife. On the boat, life will revolve around the galley, which is located prominently in the raised saloon opposite the lounge. While compact and safe at sea, there is storage and counter space that rivals what is found in many kitchens on shore. The range, hood, microwave/convection oven and sinks are the latest from GN-Espace. There is a large, top access deep freeze, a double drawer refrigerator, and a full height cool store for fruits and vegetables.
Aft of the galley in the passage to the master suite is the laundry area and pantry. Contained therein are a full sized washer and dryers, large work surfaces, and a deep sink as well as adequate storage for all the ship’s dry goods and cleaning supplies.
Sleeping accommodations are divided among a full beam master suite aft and three suites forward. Special attention has been paid to storage with large drawer banks, hanging lockers and book shelves. Access to the ship's central movie and music collection is provided via a small console on each nightstand. There are three spacious heads with separate shower stalls.
The pilothouse is large and serves equally well for navigating and entertaining. The forward part contains a helm station to starboard and a stand-up piloting area with a chart table to port. There are two sea berths so alternate watch standers can remain rested. Aft there are heated lockers for foul weather gear and boots.
As mentioned earlier, the owner took particular interest in the size and layout of the engine room. It is a full height space with a complete workbench and room for the engineer to access all components with no contortions. Equipment is selected with reliability in mind. The drive train consists of a robust, high torque Scania engine coupled to a Twin Disc MG5095A gearbox and a Hundested controllable pitch propeller.
The deck and rig are optimized for short-handed passagemaking while at the same time working well for coastal sailing with a large number of guests. All steering and sail handling is done within a few steps of the shelter of the pilothouse. Winches are operated safely from inside the cockpit. The dual helm stations in the cockpit place the driver outboard for an excellent view of the sails and a great feel for the boat’s motion. Aft of the working area and down two steps is a secure and comfortable wrap-around lounge that can seat twelve people.
The hull will be built from a 2-7/8" thick laminate of cold molded Douglas fir and western red cedar with Kevlar and fiberglass reinforcement.
