South Florida Yacht Management
Your yacht, kept ready
The approach
A captain-led program, not a loose list of vendors
Ronin Grey Marine Yacht Management is based in Miami and looks after owners throughout South Florida. Captain David Guthrie — known as Captain Poda — runs the work himself: the schedule, the vendors, the crew, and the condition of the boat.
The yachts we manage tend to be Italian and European performance boats from about 40 to 80 feet. Each program is written around how the owner actually uses the vessel, then kept current so the next trip starts from a known, ready state.

The difference
Why owners work with us
No slogans and no borrowed praise — just the way the program is actually run.
One captain is accountable
You deal with Captain Poda. The schedule, the vendors, and the condition of the yacht sit with one person, not a rotating desk.
The work is coordinated, not handed off
Yards, technicians, and finish crews are booked, briefed, and checked. You are not left to run the project from a text thread.
Presentation and systems together
Polish, teak, and wash-downs live in the same program as mechanical upkeep, so the boat looks ready and runs ready.
Clear records, no surprises in the paperwork
Invoicing, monthly reporting, and owner documents are kept in order so you can see what was done and what it cost.
How it begins
How a program starts
A straightforward sequence. Nothing is assumed until we have walked the boat with you.
1
A conversation
Tell us where the yacht sits, how you use her, and what is already in motion. No commitment at this stage.
2
A dockside walkthrough
We come to the slip, go through the vessel, and write down her condition as we find it, so the starting point is clear.
3
A written plan
You receive a proposed program covering upkeep, crew, and any yard or finish work, with a single point of contact.
4
The work begins
Vendors are scheduled, the crew is briefed, and you get regular updates as the yacht is brought onto the program.
