One Port Marine manages, navigates, and represents private yachts, commercial vessels, and waterfront assets across San Francisco Bay and beyond — quietly, and to the standard the water demands.
Owning a yacht should feel like freedom, not a second job. We absorb the operational weight — management, compliance, logistics, and the long list of specialists it takes to keep a vessel running — so you simply enjoy time on the water.
From private yacht operations and mega-yacht agency to USCG-inspected commercial vessels and the waterfront estates our owners keep ashore, we coordinate it all under one roof, on the Bay and along the West Coast.
Commercial service support available upon request.

When a mega yacht makes for San Francisco Bay, every hour counts. We clear the way ahead of arrival — coordinating port, customs, pilots, and berth — so the vessel comes alongside without friction.
One point of contact, on the ground, who knows the harbor, the authorities, and the standard your guests expect.
Pre-arrival paperwork, CBP, immigration, and regulatory filings handled end to end.
Reserved deep-draft berths and licensed pilots coordinated to your schedule.
Marine fuel, fresh provisioning, and supplier logistics arranged dockside.
Transport, technical vendors, and crew support across the Bay and the West Coast.
Beyond private yachts, we support USCG-inspected commercial passenger vessels — the Subchapter T and K platforms that carry the public and must meet every line of their Certificate of Inspection.
From qualification and day-to-day operations to the shoreside infrastructure that keeps a fleet compliant, we bring commercial-grade discipline to the water.
Certificate of Inspection preparation, drawings, stability, and USCG certification for T and K passenger platforms.
Crewing, licensing, safety management, drills, and the day-to-day running of an inspected commercial operation.
Subchapter T and K small passenger vessels sourced, managed, and maintained in class and in compliance.
Docks, berthing, moorings, and the terminal-side facilities a passenger operation depends on.
Cruising the Eastern North Pacific — from Southern California through the Pacific Northwest and up into Southeast Alaska? Wherever your vessel makes port, we can be there ahead of you.
The vessel is rarely the whole picture. Many of our owners hold waterfront homes and estates that demand the same discretion and reliability we bring to the water.
We manage the property alongside the yacht — one trusted point of contact for the residence, the grounds, the dock, and everyone who keeps them running.
Day-to-day oversight of the home, staff, and household operations.
Landscaping, docks, moorings, and shoreline maintenance handled.
Contractors, renovations, and service providers coordinated and vetted.
Quiet, dependable stewardship for family offices and private owners.
We pride ourselves on the results we deliver — discreet, precise, and accountable. When the stakes are a vessel, a development, or a reputation, the right partner makes the difference.
