Frequently Asked Questions
What is a Seabreacher?
A Seabreacher is a semi-submersible watercraft that mimics marine animals. Powered by a supercharged Rotax engine, it can breach, dive, and perform barrel rolls at speeds exceeding 50 knots on the surface.
Which Seabreacher model is best for superyachts?
The Jet Shark is the most popular for yacht use due to its compact size and storage compatibility. The X and Y models offer more dramatic styling but require larger garage space.
Can a submersible operate from a superyacht?
Yes. Purpose-built yacht submersibles from U-Boat Worx are designed for deployment from superyacht swim platforms or dedicated garages. We coordinate cradle systems and deployment procedures.
What ROV do you recommend for hull inspections?
For hull and propeller inspection, a compact inspection-class ROV with HD camera, LED lighting, and a tethered control system is sufficient. We source units rated to 100m+ depth.
Do you handle custom water toy projects?
Yes. We manage bespoke projects from concept through delivery, including specification development, builder selection, build oversight, testing, and final commissioning.
What spares should we carry for a Seabreacher?
Recommended spares include engine service kit (oil, filters, spark plugs), canopy seals, jet drive impeller, and control cable set. We supply complete spares packages.
What is the lead time for a Seabreacher?
New Seabreacher builds typically take 6–12 months depending on model and customisation. Pre-owned units and stock builds may be available sooner.
Can you arrange submersible pilot training?
Yes. We coordinate pilot certification programs through the submersible manufacturer or accredited training providers, including on-yacht practical sessions.
