Exterior Design

Seaworthiness and comfort are key components of every Sirena Yachts, and the Sirena 58 offers both. It starts with a hull design by world-renowned Germán Frers and Frers Naval Architecture & Engineering. Extensive tank testing ensures efficiency at speeds ranging from 10 to 30 knots. Vacuum-infused construction provides hull stiffness for excellent seakeeping and onboard comfort.

“It is a pleasant, sea-kindly low-drag canoe body capable of planning at high speed or cruising in semi-displacement, lowfuel-consumption mode. The hull stability is well matched to the needs of the gyroscopic stabilizers to ensure cruising or anchoring in great comfort.” —Germán Frers

Interior Design

The timeless interior of the Sirena 58 is designed by Tommaso Spadolini of Design Studio Spadolini and offers spaces equally suited to the intimate gathering of family and entertaining larger groups of friends.

“The main concept of Sirena Yachts interiors is comfort and light. When we started discussing the concept, the mission was to create a warm and elegant space, which could mix high-tech and handcrafting.” —Tommaso Spadolini

Sirena 58 - A life without compromise

The Sirena 58 is a yacht that delivers a refined experience for owners that understand what they want. The design has a timeless look, with clean, shippy lines, and offers efficient performance at a range of speeds that add cruising versatility—go for an afternoon, a weekend, or a week. The seakindly ride and comfort features will make even the most sophisticated guests want to spend more time aboard, enjoying the fine craftsmanship and amenities as they cruise from port to anchorage.

NOTE: All performance specified in the table above are design data and applies to a standard configuration boat

(standard equipment installed as per this standard list) with clean keel, propellers, and rudders. Furthermore, the

performance levels indicated above have been defined under good sea and wind conditions (Beaufort Scale level

1, Douglas Scale level 1, ambient T < 25°, seawater T =15°, atmospheric P = 103250 Pa) with 2 people on board,

25% fuel, and fresh, grey and black water tanks empty. Different or harsher sea conditions and additional selected

optional equipment may affect the performance.

Structure of the Boat

The structural design is compliant to EN-ISO 12215. The hull, deck and superstructures are constructed in sandwich technology. Entire boat have been built using the vinylester resin infusion technique and assembled with structural adhesive engineered for marine application. Thanks to the vinylester resins maximum resistance to osmosis and better surface finishing Sirena Marine is therefore able to provide a 5-year warranty against osmosis. This construction technology reduces weight and improves construction quality and consistency. Superstructure made from carbon hybrid fabrics for improved lightness and strength. Bulkheads are made in PVC sandwich and secondary bonded to the hull with lamination.

Semi-Displacement Hull

A semi-displacement vessel can take advantage of increased power and can achieve greater speeds when needed. Most of the time, semi-displacement vessel operates in displacement mode and is very fuel-efficient. Due to the lesser draft as compared to full displacement vessels, semi-displacement vessels have less “wetted surface area”, requiring less horsepower to propel the hull through the water. A semidisplacement hull can achieve about 35% more speed with the same engine load requirement as compared to a full displacement hull form, or conversely at the same speed use significantly less fuel and energy. The hard chine hull of a semi-displacement vessel is inherently more stable than a rounded bottom full displacement hull. Semi-displacements vessels are far more comfortable at anchor than any rounded bottom design.
