Clear answers aboard
Find the fault.
Understand the system.
Marine electrical problems rarely exist in isolation. Batteries, charging sources, inverters, protection, monitoring, and vessel loads all influence one another.
Tradewind Marine Electric combines hands-on diagnostics with complete-system thinking, helping owners and crews make informed decisions without unnecessary complexity.

What to expect
A clear path
from problem to solution.
- 01
Discuss
Tell us about the vessel, its location, the symptoms or project goals, and your timing.
- 02
Assess
We inspect the relevant equipment and consider how it interacts with the wider electrical system.
- 03
Recommend
You receive a clear proposed scope with suitable components and compatibility considerations.
- 04
Complete
We carry out the agreed work, test operation, and provide a straightforward handover.
Refits and upgrades
Build the power system
around the vessel.
A larger upgrade may be appropriate when you are converting to lithium, adding inverter-powered appliances, increasing charging capacity, adding solar, replacing outdated distribution equipment, or preparing for extended cruising.
We approach these changes as one coordinated system, considering safety, capacity, compatibility, serviceability, and how you actually use the vessel.

Before you request service
Frequently asked
questions.
Do you provide onboard marine electrical service in St. Maarten?+
Yes. Tradewind Marine Electric provides onboard diagnostics, repairs, installations, and refit support in St. Maarten. Share your vessel's current location when requesting service so we can confirm access and scheduling.
Do you work on both AC and DC marine electrical systems?+
Yes. We troubleshoot and work with onboard AC and DC distribution, batteries, charging sources, inverter/chargers, monitoring, switching, and circuit protection.
Can you troubleshoot an intermittent electrical problem?+
Yes. Intermittent faults require methodical testing and an understanding of how the complete system behaves. We assess the evidence before recommending equipment replacement.
Can you convert my boat to lithium batteries?+
Yes, when the vessel is suitable. A lithium conversion should account for charging sources, alternators, wiring, protection, battery management, monitoring, and the owner's real energy requirements.
Do you install Victron equipment?+
Yes. Tradewind designs Victron-centered systems that can integrate charging, conversion, monitoring, batteries, alternators, and solar into one coordinated power system.
Can you source marine electrical parts?+
Yes. We can help identify compatible parts, confirm availability, coordinate delivery to your island, or arrange pickup in Sint Maarten.
