Why now

Six reasons.

01

Tourism pays first

Hospitality carries the cash flow. Hydrogen and fish come on top.

02

A yard, not a slide deck

Built at the group's own shipyard, 350 technicians on call.

03

Repeatable engineering

The naval design is paid once and reused on every ring.

04

The permit is the moat

The anchoring permit is the critical asset. First mover on hydrogen at sea.

05

The asset can move

A ring follows the season or the event.

06

Path to Lemuria

Sea Rings pilot everything the ocean ports will need.

Investor questions

Straight answers.

Is this an offer of securities?

No. It is an invitation to talk. Terms and documents go to qualified investors after a first call.

How much is being raised?

€6–7M of equity for the first Sea Ring, plus a €2.5M EIC Accelerator application in October 2026. The 13-ring chain is a €70–90M project-finance programme.

What does an investor own?

Equity in Floating Hydrogen Ports, which designs, builds, owns and charters the rings and holds the Lemuria roadmap.

Where does the hydrogen go?

First to the ring itself. The surplus is sold to hydrogen yachts at the dock, pay at the pump.

Why hospitality on an energy platform?

The plant needs the deck anyway. Suites and a beach club turn it into the first and best-margin revenue.

Who builds the rings?

The group's own shipyard, 350 technicians on call, on class-approved floating island technology.

What is the biggest risk?

The anchoring permit for each location. It is also the moat once granted.

Can I visit?

Yes. Investors are welcome in Athens and at the shipyard.
