01 October 2025 – Today marks the official launch of SUB71, a specialist consultancy, brokerage, and crewing service dedicated exclusively to the manned submersible industry. Founded by Erik Hasselman, who brings over 18 years of experience with pioneering submersible manufacturer U-Boat Worx, SUB71 enters the market as the only independent platform offering full-spectrum support for private, commercial, and research submersible operations worldwide.

Leveraging deep operational expertise, technical insight, and a trusted global network, SUB71 facilitates every aspect of subsea ventures — from advisory and acquisition to charter, crew placement, and operational management. The company’s name reflects the fact that 71% of Earth’s surface is covered by water, a world that SUB71 aims to make safer, more accessible, and more sustainable for exploration.

“Our mission is to connect people with the subsea world, and to do so in a way that prioritizes safety, innovation, and operational excellence,” said Erik Hasselman, Founder of SUB71. “Whether it’s advising on the integration of a submersible onto a yacht, sourcing the perfect charter vessel, or supplying qualified crew, we ensure our clients can explore the depths with confidence.”

SUB71 will serve yacht owners, private explorers, research institutions, and adventure tourism operators, offering tailored solutions including:

• Advisory services for new builds, purchases, and operations

• Brokerage for submersibles worldwide

• Technical and safety management

With the growing global interest in ocean exploration and the subsea tourism market, SUB71’s launch is timely, bridging the gap between vision and execution for clients looking to unlock the ocean’s potential.
