The Architecture of Descent

An honest hybrid: marine-grade sheet iron meets structurally reinforced hardwood. Together they create a submarine that is affordable, repairable, and unmistakably ours.

Materials

Sheet Iron, Reimagined

Our hulls are formed from cold-rolled marine sheet iron, hand-shaped over wooden formers and welded by certified Finnish marine technicians. Each plate is sealed with multi-layer epoxy and pressure-tested before assembly.

  • Cold-rolled marine sheet iron, 4–8mm
  • Multi-layer epoxy sealing
  • Internal cathodic corrosion protection
  • Hand-welded seams, X-ray inspected

Structure

The Wooden Spine

Inside every Nexiloatls hull lies a laminated hardwood skeleton. Wood absorbs vibration, regulates internal humidity, and brings warmth to a cold steel cabin — a quiet nod to traditional shipbuilding.

  • Laminated oak and birch ribs
  • Marine resin saturation
  • Vibration dampening properties
  • Sustainable Nordic forestry sourcing

Build Concept

From Sketch to Submersion

Phase 1 — Frame

Hardwood skeleton CNC-cut, laminated, and resin-saturated.

Phase 2 — Skin

Sheet iron plating formed and welded over the wood spine.

Phase 3 — Systems

Ballast, lighting, viewports, and seating installed and certified.
