New cabin RIB for Guardia Civil
The latest launching from Spanish boatbuilder Aister is a fast coastguard patrol boat with a pair of 200hp Yamahas on the back.
Called S-37, it has a length of 9.70m, a beam of 3.45m with hull and cabin built entirely in aluminium.
Designed primarily for the divers of the Spanish Coastguard, this cabin RIB replaces the open boats they were using with obvious advantages that will bring to working conditions.
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 navigation.
QUICK TO PLANE
The hull has been designed to get up on the plane quickly without raising the bow excessively so that it doesn’t reduce visibility to the wheelhouse at transition speeds. Aister has also paid particular attention to the finishes, for example, the boat vents.
The patrol boat S-37 has folding sides, an in house design system that facilitates the access of divers to the water.
The cabin is designed to give 360 º degree visibility and is equipped with panoramic roofs that facilitate boarding and approach manoeuvres to other vessels, ergonomic seats for two people and two additional crew, a steering console and tubular handles that guarantee perfect mobility even when the vessel is underway.
The cabin is a walkaround unit with walkways both port and starboard up to the bow.
In addition, the boat is specially equipped with all the necessary elements to ensure its operation: large stowage area, bottle rack on deck, a davit with lifting capacity of 250kg, a 300litre bow locker for storing mooring, anchoring, rescue, firefighting and armament material and anti-puncture collar with non-inflatable flotation reserve.
PROPULSION AND NAVIGATION
Propulsion comes from two Yamaha 200HP outboard engines with two 750 litres fuel tanks. The S-37 can reach a maximum speed of 31 knots with a range of more than 300 nautical miles at cruising speeds.
Recent seatrials off Vigo demonstrated that the weight calculation study and the hull form allowed a quick transition from stop to planing, excellent stability, and exceptional behaviour during the navigation. The vessel can be turned in less than two lengths for maximum manoeuvrability in any operation or intervention. All as designed at the outset.
Aister has been building boats for the commercial marine industry for 30 years, amassing significant experience in professional aluminium boats for different State Security Bodies such as the Spanish Coast Guard and Spanish Navy.
