Astondoa unveiled the 577 Coupe at Cannes in 2026 as the sharpest expression yet of its sporting line, a 15.9-metre coupe that carries superyacht detailing into a fast, owner-driven package. The profile is low and deliberate, with a long foredeck, a wraparound coachroof and a reverse transom that opens into a transformable beach club at the waterline. A tender garage sits below, so the swim platform stays clear for swimming and sunbathing rather than storage.
Power is matched to intent. The standard twin Volvo IPS 800 installation delivers easy joystick handling and a 25-knot cruise, while an optional triple Mercury Verado V12, 1,800 horsepower in total, lifts the top end to 36 knots for owners who want the extra edge. The deep V hull keeps the ride composed as speed builds.
Accommodation runs to two cabins finished in the materials and joinery usually reserved for larger Astondoas, with generous natural light and full headroom. On deck, a single uncluttered level flows from the bathing platform through the cockpit to a helm set behind a near-frameless screen.
Built in GRP at Astondoa’s Santa Pola yard, the 577 Coupe reads as a day boat with the range and comfort for longer coastal passages. For a buyer weighing a sporty 50-footer, it offers Spanish build pedigree, a flexible engine choice and a layout built around the water.

Two very different boats share one hull here. In standard form the 577 Coupe runs twin Volvo IPS 800 pod drives, cruising near 25 knots with the low noise and tight joystick control that make pod boats so easy to berth. Owners chasing speed can specify a triple Mercury Verado V12 installation, three 600-horsepower V12 outboards for 1,800 horsepower combined, which pushes the top end to around 36 knots. The deep V forefoot carries that pace without pounding, and the 1.35-metre draft keeps shallow anchorages in reach. Fuel runs to roughly 2,000 litres, enough for comfortable coastal hops between harbours. The pod option suits relaxed Mediterranean cruising; the Verado option turns her into a sharp, high-revving weapon for owners who value acceleration.
The profile is the selling point. A long, uninterrupted foredeck and a low coachroof give the 577 Coupe a planted, purposeful stance, while the reverse transom folds down into a transformable beach club right at the waterline. A tender garage sits below, so toys and the dinghy stow out of sight and the bathing platform stays free for swimming. The cockpit sits on a single level with the side decks, and an adjustable awning extends shade over the aft seating without a hardtop’s bulk. Hull windows feed the cabins below, and the near-frameless windscreen wraps the helm in glass. Every line works toward the same idea: a clean, modern coupe that looks fast at rest and opens fully to the sea once the transom drops.
Below decks the 577 Coupe punches above her length. Two cabins are finished in the joinery, leathers and stone usually found on Astondoas a class larger, with full standing headroom and hull windows that wash the accommodation in daylight. The master takes advantage of the beam amidships, and a second cabin handles guests or family. Materials lean warm and contemporary, pale surfaces set against tan upholstery and dark detailing, so the spaces feel residential rather than sporty. A compact galley and a well-proportioned heads complete a layout designed for a couple to stay aboard in comfort over a long weekend rather than a full crewed cruise. It is accommodation sized honestly for a fast coupe, quality ahead of quantity.
Life aboard happens on one open level. The transformable beach club is the heart of it, dropping the transom to create a broad teak terrace inches from the water where a family can swim, dine or simply lounge in the shade of the awning. Forward of that, the cockpit seating converts between dining and sunbathing, and the helm stays part of the social space rather than walled off from it. The foredeck adds a second sunpad away from the action. Because the tender lives in its own garage, none of these zones is compromised by stowage. The result flows naturally from bathing platform to bow, which is exactly what an owner wants from a day boat meant to spend summers at anchor.
The 577 Coupe is built in GRP at Astondoa’s Santa Pola yard, the same facility that produces the larger Century and AS yachts, and she carries the yard’s century of building experience. A new example was listed at 1,597,000 euros in 2026, positioning her among the premium Italian coupes she competes with while offering a different build origin and the Verado speed option they cannot match. The pod-drive standard package keeps running and berthing simple for an owner-operator, and the two-cabin layout means no crew is required. For a buyer who wants a fast, beautifully finished 16-metre coupe that doubles as a swimming platform, she makes a strong case on design, flexibility and Spanish pedigree.
