Sanlorenzo 500Exp — The Explorer Yacht That Carries Everything
Photo Credit: Sanlorenzo
Picture this: you're anchored off a remote Alaskan glacier, watching your Icon A5 seaplane slide out from its onboard hangar on precision rails. The 7.5-tonne crane swings it over the water, and ten minutes later you're airborne, scouting the next anchorage 200 miles north. Back on deck, your helicopter sits ready on the aft platform, and below, a 7-meter tender waits in the garage. This isn't fantasy. This is the Sanlorenzo 500Exp, and it redefines what "go-anywhere" actually means.
At 154 feet, the 500Exp sits just under the 500-GT threshold—a deliberate choice that keeps regulatory complexity manageable while delivering 20 percent more volume than typical yachts in this class. Built on a steel displacement hull with aluminum superstructure, she's engineered for serious ocean passages with the comfort and finish of a much larger superyacht. Francesco Paszkowski drew the rugged exterior lines; Studio Indigo handled the interior, investing over €3 million in detailing and AV systems alone. The result is a yacht that looks ready for the Northwest Passage but feels like a five-star hotel inside.
Who It's For
The 500Exp is built for the owner who's done the Caribbean circuit, chartered in the Med, and now wants something different. You're 45 to 60, financially secure, and you've realized that the most memorable trips aren't the ones where you dock in Saint-Tropez—they're the ones where you anchor off an uninhabited island in Patagonia or watch orcas breach in Norwegian fjords.
This yacht suits the entrepreneurial mindset. You want capability without compromise, and you're willing to invest in infrastructure that expands your range—literally and figuratively. The 500Exp accommodates 10 to 12 guests across five or six cabins, with berths for up to nine crew. That's enough to run a serious charter operation or host extended family trips without feeling cramped. The full-beam owner's suite on the main deck includes a private drop-down terrace, his-and-hers bathrooms, and a study—because even in the Arctic, business doesn't stop.
What sets this yacht apart is toy-carrying capacity. The extended aft deck supports helicopter operations, and the custom hangar forward of the beach club houses an Icon A5 amphibious aircraft on sliding tracks with half-inch clearances. Add two Jet Skis on the foredeck, a rescue tender, SeaBobs, and a small submarine, and you've got a floating adventure base. Most explorer yachts talk about capability. The 500Exp delivers it.
Design & Layout
Externally, the 500Exp carries the industrial aesthetic you'd expect from an explorer—dark grey hull, vertical bow, purposeful lines—but Paszkowski's detailing keeps it refined. The profile is balanced, with a low-slung superstructure that doesn't fight the steel hull's mass. The extended aft deck is the headline feature: flat, open, and strong enough to land a helicopter or host 50 guests for a sunset party. When the toys are stowed, it becomes one of the best outdoor entertaining spaces on any yacht this size.
Inside, Studio Indigo's work is exceptional. The main saloon opens with sliding doors on both sides, creating natural cross-ventilation and multiple entry points. The dining table sits off to port—large enough for ten but not dominating the space—while a bar with stools anchors the starboard side. It's a proper social hub, with a TV above for casual viewing and layered lighting that shifts the mood from morning coffee to evening cocktails. The design is modern but warm, with curved architecture, natural materials, and enough original detailing to feel custom without being fussy.
The owner's cabin sprawls across the forward section of the main deck. Inside the entrance is a separated toilet compartment, freeing up space in the main bathroom for twin rain showers and a section of hull window. The walk-in wardrobe features pink paneling and matching marble—a bold choice that works. The private study includes a marble-topped desk, generous storage, and a large window for views while working. The standout feature is the drop-down terrace on the starboard side: press a button, the hull section lowers, railings rise, and you've got a private balcony over the water. Perfect for morning coffee in a quiet anchorage.
Guest accommodation on the lower deck includes two identical VIP cabins forward, each with pop-up TVs, vertical hull windows, and en-suite bathrooms finished in marble. Aft are a double and a twin cabin, both with drop-down TVs, generous floor space, and private bathrooms. Pullman berths in the double add flexibility for families. The crew quarters accommodate nine, with a bright mess featuring three large portholes and screens displaying system controls and onboard cameras. The captain gets a dedicated cabin on the bridge deck.
A full-length service tunnel runs from the beach club to the bow, linking the garage, engine room, pump room, laundry, and stores. It's rare infrastructure on a yacht this size, and it transforms crew circulation and maintenance access.
Performance & Handling
The 500Exp is powered by twin CAT C32 Acert engines—1,300 hp each at 2,100 rpm, meeting U.S. EPA Tier 4 and IMO Tier III standards. An optional configuration offers 1,340 hp at 1,800 rpm. Top speed is 15 knots (15.5 knots for the E-Motion hybrid variant). Cruise speed sits around 13 knots, but the sweet spot is 11 knots, where she delivers a maximum range of roughly 4,000 nautical miles. One hull reportedly achieved 5,800 nm at 10 knots—enough to cross the Atlantic with fuel to spare or explore the entire Pacific Northwest without refueling.
This is a displacement yacht, built for comfort over speed. The steel hull and Naiad dynamic stabilizers (fins) deliver excellent seakeeping, even in heavy weather. The helm sits well forward on the bridge deck, offering commanding visibility and a comprehensive suite of screens for navigation, systems monitoring, sonar, radar, and cameras. Wing stations on the foredeck provide repeaters for throttles, thrusters, and rudder controls, making close-quarter maneuvering straightforward despite the yacht's size.
Fuel capacity is 17,171 U.S. gallons (approximately 65,000 liters); fresh water capacity is 2,113 U.S. gallons (approximately 8,000 liters). Full-load displacement is about 1,124,000 pounds (approximately 510 tonnes), with gross tonnage just under 500 GT (around 499 GT). Draft at full load is 9 feet (2.75 meters), though some E-Motion variants quote 2.70 meters (8 feet 10 inches). Beam is 31 feet 6 inches (9.60 meters).
The 500Exp isn't about speed. It's about freedom—the freedom to say yes when the weather's perfect, to explore anchorages that require serious range, and to carry the equipment that turns a trip into an expedition.
A composite buyer scenario:
David, 52, sold his software company in 2023 and spent the next year chartering in the Med. By his third trip, he realized he was bored. The yachts were beautiful, but the itineraries felt repetitive—same ports, same restaurants, same crowds. He wanted something different: Alaska, Norway, the Galápagos. His broker showed him the 500Exp. David was skeptical at first—"Do I really need a helicopter?"—but the range sold him. Four thousand nautical miles meant he could explore the Inside Passage without worrying about fuel stops. The seaplane was a bonus. Six months after delivery, he anchored off a glacier in Glacier Bay, launched the Icon A5, and spent the afternoon flying over icefields. That evening, his family gathered on the aft deck for dinner under the midnight sun. "This," he told his wife, "is why we bought this yacht."
Lesson: The best yachts don't just take you places—they expand what's possible.
The Ownership Conversation
The 500Exp is a serious investment. Comparable explorer yachts in this class typically start around €20 million and climb quickly with customization. Annual operating costs—crew, fuel, maintenance, insurance, dockage—will run $1.2 to $1.5 million for a yacht this size, assuming 1,500 to 2,000 hours of use per year. That's roughly 10 to 12 percent of purchase price annually, which is standard for a well-maintained superyacht.
But here's the strategic angle: the 500Exp's toy-carrying capability and extended range make it a strong charter candidate. Clients pay premium rates for yachts that offer genuine expedition capability, and the seaplane-plus-helicopter setup is a marketing differentiator. A well-managed charter program can offset 30 to 40 percent of annual operating costs, turning the yacht from a pure expense into a lifestyle asset that partially funds itself.
Crew is non-negotiable at this level. You'll need a captain, engineer, chef, two or three deckhands, two or three stewardesses, and possibly a dedicated pilot if you're serious about the seaplane. Nine crew is the standard configuration, and salaries, benefits, and training will account for 40 to 50 percent of your annual operating budget. The good news: the crew quarters on the 500Exp are excellent, which helps with retention.
Maintenance is predictable. Steel hulls require more attention than fiberglass, but they're also more forgiving in remote anchorages. Budget for annual haul-outs, bottom paint, and regular engine servicing. The CAT C32s are workhorses—reliable, well-supported globally, and relatively fuel-efficient for a yacht this size.
Where to Start
The Sanlorenzo 500Exp is the yacht you buy when you're done pretending. It's not the flashiest option, and it won't win drag races with sportfishers. But if your idea of a perfect weekend involves anchoring somewhere no one else can reach, launching a seaplane at sunrise, and hosting dinner for ten under the stars, this is the yacht that makes it happen.
