Martronics provides recommended electrics and electronics services to yachts of various sizes in St. Thomas. Owned and operated by Herman Vanderheide (ABYC qualified), Martronics offers a wide range of electrical and electronic services including Autopilots, Satellite systems, Wind / Speed, Depth and Multi-Function Displays (MFDs), Charging systems, and AC and DC systems. Herman has a good working relationship with many major electronics companies including Furuno, SeaTel, B&G, Raymarine, MasterVolt, Garmin and KVH (plus other brands regularly seen on high quality yachts). 

As Herman works alone, during the season his schedule is often busy, so it is worthwhile contacting Herman in advance to schedule his services. Feedback for his reliable services includes: "I have no issues in recommending him for his electrical works on board superyachts – clean, efficient and on time.” 

Available seven days a week and throughout the off-season too.
