Astondoa's TopDeck 65 is more than meets the eye, especially at anchor.

65_ASTONDO-63 Much of the yacht expands into what from above looks like a private island. The boat unfolds at the stern and sides to increase the square footage of available at-anchor fun space. The transom folds down to create a swim platform, and the sides of the cockpit fold outward, to add space to the already good-sized dance floor. In addition, about two-thirds of the sides of the top deck fold out to create deck space for a cocktail party, which is enhanced by a hot tub whose aft wall is clear.

The open-air top deck is socially adept. Aft is the aforementioned hot tub. Just forward of that is a bar with three stools on one side and a barstool-height bench settee opposite. Forward of that is a conversation/dining area, with bench settees on either side of a large table. Lower the table, add a couple of large filler cushions and open the sunroof, and the conversation pit becomes a rather expansive sun lounge.

Forward of that is a wet bar, an outdoor galley — the grill stows away in its own drawer — and the helm. Forward of that is a bow relaxation area that includes a large sun lounge and a C-shaped settee around a small table, under an available umbrella.65_ASTONDO-46

The interior has a sleek and modern look. In the bow, the salon is equipped with everything one needs to entertain, including a wet bar, a large flat-screen TV and a video game console. A small galley shares the space. Two staterooms are side by side amidships. The owner’s has a double bed, while the guest room includes two singles, though owners can alter that layout.

Twin Volvo Penta D-11 IPS950 engines, each cranking out 725 hp, power the 65-foot TopDeck 65. Its top speed is 25 knots, and at its cruising speed of 20 knots, it achieves a range of about 330 miles. Astondoa, astondoa.com
