Martronics provides recommended general electric AC & DC services to yachts of various sizes in St. Thomas since 2002. Owned and operated by Herman Vanderheide (ABYC certified), Martronics offers a wide range of electrical services for both AC and DC installations; including troubleshooting, repairs, maintenance and new installations together with sales, service and repair of various electrical components. 

As Herman works alone, during the season his schedule is often busy, so it is worthwhile contacting him in advance to book his services. Feedback for his trusted reliable expertise includes: "I highly recommend him for his analytical work troubleshooting electrical issues on board (super) yachts – his work is clean, efficient and done in a timely manner.” 

Available seven days a week, including during the summer off-season (the hurricane months).
