Designer's Comments
Passagemaker Lite hull #1 is under construction at Moondance Yachts in Capetown South Africa. The 48’6” (14.8m) cedar-strip-planked Ataraxia will be used for Southern and Atlantic ocean-crossing and as a full-time liveaboard home for her owners, a European couple currently living in SA to oversee their vessel's construction and fitout. Ataraxia will reach her hull speed of 9.2 knots using less than half her installed horsepower. Short coastal cruises will be done at 10+ knots and ocean crossings at 8+.
Passagemaker Lite Ataraxia is a Passagemaker Lite 46 plus, the "plus" indicating increased length for added interior volume over the original 46' design. She is built of fiberglass sheathed Japanese Cedar strip-planking on NC cut station molds. The deck will be sheathed plywood over laminated African mahogany beams for a warm, traditional interior. All major structural members, keel, floors, engine stringers, and clamps are laminated African mahogany.
The owners are experienced sailors, having lived aboard and cruised the Atlantic in their previous boat, an aluminum sloop. Reasons for going to a new boat and choosing the Passagemaker Lite include increased interior volume, better privacy between spaces, an attractive interior space (pilothouse) with a view, the opportunity to use modern technology in construction and systems, and efficient use of fuel over long distance ocean cruises.
The 48'6" Passagemaker Lite's arrangement includes a large owner's cabin with a centre line double berth in the bow. Just forward of the pilothouse is the split head, with wc and sink to port and a large shower to starboard. The pilothouse has helm station forward to starboard, with bridge deck access immediately aft. Access down to the main saloon aft is just to starboard of centre line, and the entire port side is a large raised settee with table and bookshelves behind. Main fuel tanks are under the pilothouse. Down three steps aft of the pilothouse is the large wrap-around galley to port and the guest cabin/office to starboard. Aft of this is the full width main saloon with L seat and dining table to starboard and two swivel chairs opposite. The aft bulkhead has a watertight door with window into the engine room, and a curved stairway up to the afterdeck.
The afterdeck has a stair down to the swim platform and steps port and starboard up to the boatdeck forward over the saloon. On centre line in the aft deck is a large (48" wide and 30" fore & aft) hatch opening into the engine space. Immediately under this hatch are the twin engines and v-drives, easily available for engine checks or maintenance without disrupting the ship's interior. The boatdeck is roomy enough to carry a 12' hard boat on centre line, lifted on and off with the mast and boom forward. Forward on the boatdeck level is the outside command bridge, which can be enclosed with plastic curtains and hard or soft top. This area includes an outside seating area, helm on centre line, doors to the sidedeck P and S, and the ladder down forward into the pilothouse. All the way forward is a secure well deck for anchor handling with a massive chain locker below and forward of the watertight collision bulkhead.
Roll attenuation and comfort at sea are real concerns throughout the Passagemaker Lite design. Heights above waterline are minimized, as are weights. The pilothouse is low and amidships for minimal motion, the main saloon and galley are very low for the same reason. Weights are centralized where possible; the largest single weight in the boat is the fuel load, which is positioned down low amidships, as is the water storage. While the owners of this first Passagemaker Lite have chosen to install passive paravane stabilizers, other options are available. These include provision for the inclusion of active hydraulic fins, and bilge keels show some promise without the worries of other systems. But bilge keels will never reduce roll as much as the paravanes will with equal or less drag.
The trade off of a lighter weight and smaller volume Passagemaker Lite vs the typical heavy, wide Passagemaker is a higher cruising speed with less fuel consumption, and a livelier motion underway. With her long and fine lined waterplane, the Passagemaker Lite 46 plus will reach her hull speed of 9.2 knots using less than half her installed horsepower. Short coastal cruises will be done at 10+ knots and ocean crossings at 8+. While the tradeoffs are a personal choice, I look forward to exploring the possibilities as we build more of these new generation passagemakers.
