Overview
The C-Researcher series pushes the acrylic pressure hull further than any other manned submersible, with certified configurations diving to 3,000 metres.
Every C-Researcher pairs research-grade capability with the comforts U-Boat Worx is known for: air conditioning, Bluetooth audio, and an integrated acoustic underwater telephone for ship-to-sub communication.
Low-height (LH) variants are purpose-built for superyacht garages, bringing serious depth capability to vessels with limited hangar height.
Safety Systems
- Maximum Depth Protection — automatic ascent if certified limits are exceeded
- Deadman's Switch — automatic resurfacing if the pilot is incapacitated
- 96-hour emergency life support as standard
- Manually releasable emergency drop weight
- Dyneema safety buoy rated to 1.5× operating depth
- Acoustic pinger for underwater location tracking
- DNV certified design, construction and testing
