The Astondoa 65 Top Deck’s transformative swim platform and upper deck make her a mammoth day boat.

Astondoa's 65 Top Deck takes day boating to the extreme, with the ability to hold 30 guests. At anchor, the upper deck and swim platform unfold like lotus petals. That swim platform is 270 square feet when the sides are open, while the upper deck measures 1,350 square feet.

Getting a yacht to fold open requires serious engineering. In addition to ensuring that the hydraulic system for the “wings” would be reliable in salt water, the Spanish builder had to construct the teak sections on the wings to meet the opening system’s weight requirements. Astondoa also gave the swim platform a submersible section for diving or launching a tender, with an adjoining garage for water toys.

This yacht’s open upper deck is where the party happens, with an ­alfresco dining area, six-person hot tub overlooking the stern, bow sun lounge and lots of seats. A big-screen TV lifts from a forward console.

Buttoned up, the 65 Top Deck has a top speed of 25 knots and a cruise speed of 20 knots with twin 900 hp ­Volvo Penta 1200 diesels with pod drives.

The tender garage doubles as a beach club when the toys are in the water. Its umbrellas provide shade, and a day-head is inside. This area can be converted into crew quarters.Courtesy Astondoa
