The Guardiao is the Cape Verde Coast Guard's first patrol vessel based on the Damen Stan 5009 design.
The Guardião is equipped with a vertically aligned "axe bow". Damen asserts that a vertical bow has an advantage over a traditional clipper bow, when piercing waves. The clipper bow has more buoyancy when it pierces a wave, which causes the bow to rise and fall with greater intensity—which triggers seasickness in susceptible individuals. The Guardião was the first patrol vessel built to a Damen axe-bow design to be launched.
Her crew of 18 either have their own cabin, or share a double cabin.
The Guardião is equipped with a stern launching ramp, allowing it to deploy and retrieve a 7 metre high-speed daughter craft, without first coming to a stop.
The Guardião is equipped for the short-term seating of up to 76 individuals, in the case of at-sea rescues, or the interception of undocumented migrants.
In 2016 the Guardião participated in a joint exercise with US and Belgian vessels.
