The Phantom 400 carries Schaefer’s reputation for cockpit space into a compact 12.25 metre package. Brazilian-built and drawn by Marcio Schaefer, it answers a specific brief: a hard top express cruiser that gives up nothing aft. The bathing platform runs wide, the gourmet station sits where owners actually use it, and the transom seating turns the stern into the main living area rather than an afterthought.
Below, the layout is unusual for the class. Two full cabins, both with generous headroom, give the Phantom 400 an overnight capability that most 40 foot hardtops cannot match. Five berths make weekend cruising realistic for a family rather than a compromise. Natural light reaches the accommodation through deep hull glazing, and the finish carries the same detail the yard applies to its larger 510 and 600 models.
On the water the deep-V hull, with 17.4 degrees of deadrise at the transom, settles quickly and tracks cleanly. Twin Volvo Penta diesels sit under the cockpit sole, keeping weight low and the accommodation quiet.
For a buyer, the Phantom 400 sits in a useful place: enough boat for coastal passages and overnight stays, small enough for a single owner-operator to handle without crew. Schaefer’s Florianopolis yard has built this hull since it was known simply as the 400, and the model has a settled following in the Brazilian and North American markets.

A hard top is the first clue this boat is built for real use, not just display.
Marcio Schaefer drew the Phantom 400 with a retractable hard top over the helm and a foredeck fitted with a full length rail, a generous sun pad and three round hatches that bring light below without needing a window. The hull is vacuum-infused fibreglass over a foam core, built in Schaefer’s own Florianopolis yard on a five-axis CNC process that keeps tolerances tight across every panel. A deep-V hull with 17.4 degrees of deadrise at the transom sits under all of it, the geometry that gives her a settled, predictable ride rather than a harsh one. Nothing here is decorative. Every element earns its place through use.
She plans in under six seconds and never feels like she is working to do it.
Twin Volvo Penta D6-380 diesels on DuoProp drives are standard, with a 400 horsepower pairing available for owners who want a faster cruise. The result is a 25 knot comfortable cruise and a 33 knot top speed, figures that hold steady because the engines sit low under the cockpit sole, keeping weight out of the topsides. The deep-V hull tracks cleanly through a chop rather than skipping across it, and the boat settles back onto the plane quickly after easing off the throttle. For a single owner-operator without crew, predictable handling matters as much as outright speed, and the Phantom 400 is built around that priority rather than against it.
The stern, not the saloon, is where this boat is lived in.
The bathing platform runs wide enough for genuine use rather than a quick step ashore, and a gourmet station with a sink and grill sits right where the cockpit crowd actually gathers, next to a folding teak table built for meals rather than drinks balanced on a knee. Transom seating wraps the full width of the stern, turning what other 40 foot hardtops treat as leftover space into the main social area. Fourteen day guests fit across the cockpit without anyone standing in a doorway. It is a boat built around the idea that owners spend a cruise on deck, not inside, and the layout backs that up rather than just claiming it.
Two full cabins on a 40 foot hardtop is rare. Five berths rarer still.
The forward cabin takes an island berth with full standing headroom, and a second cabin amidships offers a convertible arrangement that suits a couple or two children depending on the trip. Each cabin has its own ensuite bathroom, a detail most boats this size reserve for the owner alone. Deep hull glazing brings genuine daylight into both cabins rather than relying on hatches overhead, a touch borrowed from Schaefer’s larger 510 and 600 models. For a family or two couples cruising together, it is enough accommodation to make a long weekend practical rather than cramped, which is unusual at this length.
One tank, 174 nautical miles, no need to plan around a marina.
An 800 litre fuel tank gives the Phantom 400 enough range for a genuine coastal passage at her 25 knot cruise, without the owner having to chart a course around where the next fuel dock sits. That autonomy matters more on a boat built for a single operator than it would on a crewed yacht, where refuelling is somebody else’s problem to solve. Combined with her shallow enough draught and compact length, she can reach anchorages a larger motor yacht would have to pass by, and get there and back without topping up along the way. It is a practical kind of freedom, not a headline one, and it suits exactly the owner this boat is built for.
