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 efficiant. 

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 semi-displacement 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.

Structure design

The structural design is compliant to EN-ISO 12215. The hull, deck and superstructures are constructed in sandwich technology. Entire boat has been built using the vinylester resin infusion technique and assembled withstructuraladhesiveengineeredformarineapplication.Thankstothevinylesterresinsmaximumresistance to osmosis and better surface finishing Sirena Yachts is therefore able to provide a 5-year warranty against osmosis. This construction technology reduces weight and improves construction quality and consistency. Deck and superstructure are made from Carbon hybrid fabrics for improved lightness and strength. Bulkheads are made in PVC sandwich and secondary bonded to the hull with lamination.
