2026 Sirena 42

The Sirena 42 is a steel-hulled superyacht designed by Luca Vallebona with naval architecture by Van Oossanen Naval Architects. Powered by twin MAN diesel engines producing 2,900 horsepower, she reaches a maximum speed of 15.5 knots and cruises at 10 knots. At 138 feet in length with a 29-foot beam, she displaces 435 GT and is built using a fast displacement hull form.

Accommodations span ten cabins with twelve heads across multiple decks. The owner's suite can be positioned on either the main or upper deck and includes the option of a private patio with direct outdoor access. Four guest staterooms occupy the lower deck, including two VIP suites with transverse berths. The interior layout is fully customizable, allowing for flexible configurations of formal dining, casual entertaining, guest lounges, or additional social spaces.

Notable amenities include an aft pool, fold-out bulwarks, and an optional forward Jacuzzi. The design provides multiple stateroom layout options to suit individual preferences, with the flexibility to prioritize formal entertaining, private retreats, or open social gathering areas throughout the yacht.
