According to Significant Small Ships of 2004
The Italian Ministry of Environment ordered 30 fast boats for removing rubbish and floating debris from protected coastal areas. The first craft was delivered in 2003. A short response time was requested leading to a minimum speed requirement of 20 knots. Therefore, the hull is Gull-shaped, as a balanced compromise between the large deck area of a catamaran and the seaworthiness of a monohull.
The craft is equipped with twin Volvo Penta stern drives, each delivering an 110kW output. It achieved a top speed of over 25 knots during sea trials.
Refuse are hauled in through different ways: using hand equipment; using a small folding crane (for loads up to 280kg); or using an electro-hydraulic stainless steel basket positioned forward. Once deployed, the basket remains about 0.20m below water line in order to collect all the floating debris which is collected into a removable 20m3 rubbish tank.
