Patrol boat RAL-1100-ZSF-CABINADAoutboardaluminum

In AISTER we’ve just delivered a new aluminium fast patrol boat for the Spanish Coast Guard. The boat will be utilised for numerous missions including surveillance, search and rescue and diving operations, improving the working conditions of the security force.

This new fast patrol boat, called S-37, has a length of 9.70 m, a beam of 3.45 m with hull and cabin built entirely in aluminium because this material offers several advantages such as lightness, stability, durability and structural resistance.

With the S-37 the divers of the Spanish Coast Guard will have a new aluminium fast patrol boat adapted to their working conditions since the unit used inflatable boats without cabin and that was not suitable for the daily services that they are making.

Design and Equipment
The fast patrol boat has been designed with close attention to ergonomics and working environment. The hull has a wide beam to give stability to the vessel and has been equipped with five watertight compartments. The cabin is three sided and has been developed to facilitate workflow coordination during the navigation.

The hull has been designed with special care in the forms to ensure that the glide of the boat become in the shortest time possible, without raising the bow excessively so that it doesn’t reduce visibility to the wheelhouse. On the other hand, our team has also paid particular attention to the finishes, for example, the boat vents.

The patrol boat S-37 has folding sides, an own design system that facilitates the access of divers to the water.
