# Ship
Ships are object targets and should not be forced into a pure semantic
segmentation class. Use polygon or instance heads when annotations support it.
## Required Context
- Ports, aquaculture grids, bridges, and bright wave wakes are hard negatives.
- SAR and optical ship extraction should be sensor-aware.
