THE MARK

A mark on the hull cannot exaggerate.

A mark on the hull cannot exaggerate.

The mark is our starting point: a clear record of what happened, who confirmed it, and what still needs attention. We are building Hullmark for crews and shoreside teams who need vessel work to be easy to record and easy to follow. This demonstration shows the direction. The application is in private testing.

Shore stops asking. Shore starts seeing.

The planned shoreside view brings vessel records and open defects into one place. Follow the same job from the boat to the shore office, with its crew notes and photographs together. This board illustrates the intended view; it is not live vessel tracking.
