She works harder than most 42 footers, and it shows.
A tender garage with its own crane means the D42 can carry and launch a proper dinghy without turning the cockpit into a storage problem, a feature neither the D32 nor the D36 in this range offers. The cockpit itself runs an outdoor galley, with an ice maker available as an option, built for entertaining rather than simply surviving a day trip. A dinette that converts into three separate configurations lets the same space serve lunch, lounging or an extra berth depending on what the day calls for. None of it reads as excess: every addition earns its place on a boat built for owners who use their time on the water rather than photograph it.
The largest boat in the range still reads as a walkaround.
A broad swim platform and a generous aft sundeck define the stern, with the tender garage and its crane tucked beneath, keeping the transom clean rather than cluttered with davits or exposed machinery. Forward, the deck steps up toward a tall, spacious bow section that gives the forward cabin genuine headroom rather than a crawl space. The beam, at exactly 4 metres, is wide enough to let the cockpit and sundeck breathe without pushing the D42 into motor yacht proportions. De Antonio’s in-house design team keeps the surfacing consistent with the smaller D32 and D36, so the family resemblance is deliberate rather than coincidental across a range that spans more than four metres in length.
Below deck, the D42 trades one open cabin for genuine separation.
A lounge style space sits beneath the helm, offering a sheltered retreat distinct from the two sleeping cabins, itself a step up from the simpler forward berth layouts on the D32 and D36. The bow cabin is tall enough to stand in comfortably, a detail the smaller boats in the range cannot match, and a bathroom with a shower sits between it and the lounge, serving both without forcing guests through someone else’s space. Two cabins sleep four, with a single crew berth available for an owner who wants a second pair of hands aboard rather than running the boat single handed. It is accommodation built for actual use over several days, not simply a berth to tick a box on the spec sheet.
At 350 nautical miles, she can cross more sea than most owners need.
A 1,200 litre fuel tank, the largest in the De Antonio range covered here, gives her that 350 nautical mile range at a 25 knot cruise, with a 45 knot top speed available when the schedule calls for it rather than the scenery. The standard twin engines can be upgraded to a 400hp Volvo Penta pairing or a triple 400hp Mercury Verado configuration, both aimed at owners who want to trade some of that range for outright speed rather than endurance. Either way, the numbers put real distance within reach of a single day: island hopping, extended coastal runs, or simply the confidence of a wide margin in reserve before the next fuel stop becomes a concern.
Everything on the D42 is built to convert, not sit idle.
The dinette alone offers three configurations, shifting between dining, lounging and an extra berth without needing separate furniture for each. The aft sundeck does double duty over the tender garage below, and the outdoor galley keeps meal preparation in the cockpit rather than forcing guests below deck during the day. Twelve day guests can be aboard comfortably, four of them staying the night across the two cabins, with a crew berth kept separate from the guest accommodation entirely. It is a layout built around flexibility rather than fixed zones, each space earning a second purpose so the D42 can serve a full day of entertaining and still settle into a quiet overnight without reconfiguring much at all.
