Cross Water Modular

The Modular Aluminium Base Platform That Integrates It All.

The breakthrough isn't complexity — it's integration. Cross Water Modular combines the essentials into one durable, mission-ready platform so you can configure the boat for today's work, scale production confidently, and evolve capability over time.

  • Field-proven platform
  • Scaled-production ready
  • Ready for fast reconfiguration
  • Designed for future autonomy

One Platform. Configurable Missions.

Cross Water Modular is a professional grade maritime platform with plug and play modules. Consoles, seating, machinery, racks and mission equipment are added, removed or reconfigured within minutes — without structural changes to the hull. The same core hull, designed for a 25+ year service life, evolves capability through modules and upgrades instead of through new hulls.

Nordic Engineering. Responsible Autonomy.

Cross Water is engineered for demanding Baltic and Nordic conditions. We believe that serious maritime work deserves serious engineering — marine-grade aluminium, integrated design, modular evolution, and a 25+ year service life. On autonomy, we take a deliberate posture: manned performance now, autonomy-ready by design. Automation is an upgrade path, introduced when reliability, training, and regulatory acceptance are ready. The hull is built to accept autonomy over its service life, not to claim it prematurely.

Simple mechanical innovation. Massive operational value.

A workboat should not be a collection of add-ons fighting for space. It should be a platform where the essentials are integrated from the start — structurally, electrically, and operationally. That's what makes Cross Water Modular different: fewer compromises, fewer failure points, cleaner workflows, and a boat that can be reconfigured without rebuilding.

Integration reduces complexity

Hull, rails, drainage, electrics, and motion support are engineered as one system — not bolted on after the fact.

Standardized interfaces speed up changes

Modules attach to anodized rails flat to deck. Reconfigure consoles, seating, racks and mission gear in minutes.

Cleaner decks improve safety and efficiency

Fewer obstructions, fewer failure points, faster service access. Workflows stay clean under demanding duty cycles.

Base platform — the core of Cross Water Modular

The base platform is the foundation for every configuration. It is designed to integrate it all — hull structure, modular mounting, drainage, motion support systems, electrics, and service access — so mission modules can be added fast and reliably. The result is a platform that is field-proven in demanding conditions and ready for scaled production.
