The story

How it stays out there

Twenty seconds on what makes two hundred days possible.

Scroll

01 / 06Launch

It leaves on its own

Lifted in by crane, released, gone. From then on the mission runs from a screen.

The sail drone sailing away from a rocky coast at golden hour

02 / 06Wind and sun

Nothing to refuel

A rigid wing sail moves it, solar panels feed the sensors. Endurance ends with fouling, not with fuel.

03 / 06The hull

Composite, built in Assemini

Carbon and epoxy from a yard that builds racing structures, light enough to sail in a breath of wind.

04 / 06Below the waterline

It listens

Hydrophones on the keel and a quiet hull above them. Acoustic monitoring is the payload it was designed around.

05 / 06The fleet

One drone is a sensor, a fleet is a picture

Vessels hold station or move as a line. The control room reads them as one instrument.

06 / 06The service

You buy sea days, not hulls

The fleet stays ours. You receive the data, from a single day to a season.

The state of a pipeline.

One platform, three lines of work: public bodies and the environment, defence, energy. The same hull with a different payload.

The platform

Maistrale, a sail drone for the Mediterranean

Six metres and eight of composite hull under a rigid wing, with the sensors below the waterline and the links on the mast.

  • Wind for propulsionA rigid wing sail, trimmed by the autopilot. No engine hours, no fuel on board.
  • Sun for the sensorsDeck solar panels and a battery bank sized for the Mediterranean winter.
  • Acoustic firstHydrophones on the keel pod and a hull with nothing that hums. Built for listening.
  • Three linksSatellite, LTE near the coast, VHF and AIS. The control room is never out of reach.
  • Racing compositesCarbon and epoxy laminated in Assemini, in the yard that builds racing structures.
  • Swappable payloadFour configurations on the same hull. The payload bay changes in a morning.

Where

The Mediterranean in two hundred days

Eight example missions from the base in Cagliari, one per kind of customer. None has been flown yet: the first hulls are in build.

How it works

From a request to a dataset

You do not buy a drone. You buy the days it spends at sea and what it brings back.

  1. 01

    Brief

    Area, duration, what you need to know. We size the payload and the number of hulls.

    One week
  2. 02

    Launch

    By crane from a quay or from our yard at Cagliari. A drone is at sea within a day of leaving the truck.

    One day
  3. 03

    Watch

    The control room plans, monitors and re-routes. You see the same picture on your screen.

    Every day at sea
  4. 04

    Deliver

    Data streams during the mission and lands as a dataset at the end, in your format.

    Continuous
How operations run

Three lines

Same hull, three customers

The limestone cliffs of the Sardinian coast over clear water

Environment

Public bodies and the environment

Water quality, protected areas, seagrass, illegal fishing. Weeks of presence where a survey vessel comes once a year.

  • Regions
  • Marine protected areas
  • Port authorities
  • Research

Defence

Defence

Persistent acoustic surveillance from a platform nobody hears. Contacts, tracks and alerts to the navy that owns the picture.

Energy

The yard

Built where racing boats are built

Pedra Rubja is a composites yard first. Clean room, autoclave, five-axis milling and a team that laminates carbon for racing programmes.

The drone is built with the same processes, in the same hangar. That is why the hull is light, why spare parts exist, and why a repair does not wait for a supplier.

Investors

A fleet is being built. So is the round.

A Sardinian yard with racing composites, a sailor at the helm, and a Mediterranean that nobody watches from the water for more than a day. The case, the roadmap and the ask, on one page.
