Carbon-Fiber Human Submarine Build

The design package for my one-person, pedal-driven submarine is finished; what I need now is a seasoned composite builder to turn those drawings into a seaworthy vessel. Your main focus will be full construction and assembly.

Hull & Materials
The outer shell is specified as a carbon-fiber monocoque laid up with epoxy resin and vacuum infusion. Internally, an aluminium space-frame supports the drivetrain, controls, and safety gear. You’ll source, cut, machine, and finish all aluminium components, then bond or bolt them to the cured hull per the drawings I will supply on award.

Buoyancy Strategy
Instead of active ballast tanks, we will embed closed-cell foam sections inside the hull and fine-tune trim with removable lead weights. Precise placement is critical, so you’ll need to work closely with me on weight calculations before final sealing.

Key Tasks
• Fabricate and cure the carbon-fiber hull to the specified laminate schedule.
• CNC-machine or otherwise produce aluminium bulkheads, seat rails, prop-shaft supports, and control linkages.
• Dry-fit, then permanently assemble all parts, ensuring watertight seals around shaft penetrations and viewport.
• Conduct leak and pressure tests to 3 bar (≈30 m) and document results with photos and data sheets.
• Pack or crate the finished craft for safe road transport to my workshop.
