About JTB Marine

Our Marine Service division is headed by Capt. Charlie Johnson, PE. Charlie, a liveaboard cruiser with thousands of blue water and coastal miles under the keel, is a registered professional engineer with mechanical and nuclear specialties, a USCG licensed captain with 100 ton and towing certificates, an ABYC certified marine electrician and a retired Naval Officer who specialized in repair and maintenance of our nation’s nuclear submarine fleet. And he’s a really nice guy, too!

Since founding JTB Marine Service, Charlie has evaluated, recommended and installed power systems, wiring, electronics and all manner of related equipment aboard pleasure boats ranging from mega yachts to catamarans, sail and power, old and new, including the complete design, procurement and installation of all systems aboard a renovated 46’ classic wooden pilot boat.

His 35 years of experience in marine systems and repair, and his own six-year cruise from Washington, DC to Venezuela and back gives Charlie a unique tool bag of expertise and know-how.
