A new relationship between people and the sea

For everyone,
a chance to touch the sea
and a new Age of Discovery.

A community sharing boats, fishing ports, and marinas to create a fluid maritime market. Based in Shonan, Japan, we’re building a lifestyle that lets you work and sail at the same time.

Our Mission

“ So that everyone can enjoy the sea, freely. ”

Through new rules and modern technology, we keep pursuing freedoms that haven’t been possible until now.

We’re working to lower every barrier to getting on a boat. By rethinking ownership, operations, and information, we open the sea to be more accessible and more equitable — that’s the Age of Discovery we envision.

What We Do

Four pillars for a new relationship with the sea

We are not just an event organizer — we are a group building infrastructure so anyone can enjoy the sea. Transparent operations, fair value distribution, and growing the network of stakeholders are at our core.

Distributed Ownership In Development

Sharing boats, ports, and marinas across all stakeholders to create a fluid maritime market. As a first step, we’re bringing the founder’s boat into an LLC-style DAO and validating the legal and operational model.
