North Sea Boats Built Fast Attack Craft Launched With MAFI Equipment

Is this the next generation of military maritime prowess? The Fast Attack Craft (FAC), built by North Sea Boats showcases a sleek "Wave Piercing" trimaran design. Built to slice through the water rather than skipping over it, its wide beam ensures its stability. 


This design allows for smoother, faster travel, even when the sea is less than calm and I'm sure you will agree it looks amazing. I'm pretty sure I wouldn't want to be chased by it!


Stealth capabilities are at the heart of the FAC's design. It's engineered to fly under the radar, so to speak, with technology that lowers its visibility by diminishing radar, infrared, acoustic, and magnetic emissions. The absence of traditional reverse-angle bows cuts down on radar bounce-back, making it even stealthier. Its arsenal is also cleverly integrated into the ship’s structure to maintain a low profile.


With a top speed of 30+ knots, both cooling and salt water ingress management are essential to peak operations. Marine Air Flow was honoured to be a part of this project in conjunction with North Sea Boats. I'm sure you will agree this vessel is a weapon (pun intended!).

Operating any vessel in the Indonesian area and keeping it cool is quite the feat. Add in the speed at which the KRI Golok does, and its super important to  maintain a salt free and cool environment.


We chose a two stage air intake system, primarily for its capabilities in larger seas. In conjunction with the double stage grilles which we used on the air intakes, we used single stage grilles for the air outlets.


Our High Volume Fans with 2.2kw motors were added in conjuction with stainless steel air dampers, air diverters to direct the air around the engine room and security panels to protect the crew from the high speed fans.

KRI Golok Information

Manufactured for the Indonesian Navy, this incredible vessel was designed by LOMOcean Marine. With a design coming from our southern neighbour of New Zealand, and delivered to our northern neighbour of Indonesia, this project felt very close to home for Marine Air Flow.


We have worked on a few projects for North Sea Boats, but this one was a favourite for sure.  Brad has even added a poster of this boat to the office walls!
