In full compliance with S.O.L.A.S. new requirements, the new rescue boat SV-420 design increases both length and beam, providing a 25% increase on the usable room on deck compared to the previous model (SV-400).

Therefore the new rescue boat SV-420 enables to place the new compulsory stretcher on deck, in order to enable placement of at least one injured person. Additionally, the SV 420 has transverse seats for all the passengers and a bow locker to store all the necessary equipment.

This new length rescue boat intends to improve boat capacity and performance, allowing a quicker and more effective answer when facing an emergency situation.

SV-420 complies with SOLAS 1974 as amended and also with the Directive 96/98/CE, amended by the Directive 2002/75/EC on Marine Equipment (MED), under the EC TYPE-EXAMINATION CERTIFICATON MED-B-9277. According to this certification, the SV-420 and SV-480 can be fitted as rescue boats in all vessels with Community flag and in any country where SOLAS rules are accepted. Each boat is supplied with the relevant Conformity Declaration, identification plate and with maintenance and user manuals.


Hand-made by the traditional LAYER-OVER-LAYER, thus allowing their individual control, one by one, avoiding osmosis and other possible faults, quite frequent in other production processes. UNSINKABLE-MONOBLOCK-GRP laminated hulls, pressure-compacted with POLYURETHANE closed cells, achieving a solid body soundless and without vibrations. Even if the hull is accidentally broken, the boat still floats.


Produced with last generation Tritex®, a DOUBLE-THRED HIGH-TENACITY POLYESTER fabric calenderer on both sides with the latest technology formulas, more resistant to weathering, tear and abrasion. It withstands temperatures between –30 C and +70 C.


All joints are assembled by THERMO-WELDING with reinforced strips bonded together into a single body, more resistant than Tritex® material itself.


They automatically release the excess of pressure produced by mistakes in the inflation process or by the increase of temperature, thus avoiding eventual burst.


The production of all NARWHAL boats, including the rescue boats, is certified by the System of Quality ISO 9001:2008, under #149609-2014 AQ-IB-ENAC, which ensures the control on the different stages on the production process and certifies the right management and design of every single boat.


The demanding tests the rescue boats have successfully been through in order to achieve SOLAS approval, guarantee that they can perform their role as rescue boats even when facing the most adverse situations. The boats are guaranteed for ONE YEAR by the manufacturer in normal conditions of use and maintenance and in subject to the GUARANTEE  DOCUMENT.
