30 Years of Maritime Experience Working for You.
At GreenStone Marine, we don’t just help clients buy vessels, we help them own them successfully. With expertise spanning the bridge, the shipyard, and the brokerage floor, we guide owners through acquisitions, new builds, refits, and operational setup with one objective: protecting your investment at sea.
GreenStone Marine was founded on a simple principle: successful vessel ownership requires more than a transaction, it requires experience.
With over three decades in the maritime industry as a Captain, Broker, and Project Manager, our leadership provides a rare 360-degree perspective on vessels, from design and construction to operation and long-term value.
We help clients make informed decisions so their vessel remains a source of confidence, not costly surprises.
The “Unicorn” of the maritime world is just a phone call away—a true owner’s representative. With a resume that spans from the bridge (Captain) to the boardroom (Broker) and the shipyard (Project Manager), this person bridges the gap between the dream of owning a vessel and the cold, hard reality of operating one and the expenses.
Here is why that specific combination of 30+ years of experience is the ultimate “cheat code” for a buyer or sellers:
