Overview

Sure Shot Marine provides electrical and onboard systems diagnostics for sail and power vessels in the San Francisco Bay Area. I focus on identifying and resolving system issues using measured data and defined test procedures, with clear documentation and practical recommendations.

Inconsistent charge behavior, overheating, unexpected low voltage, or poor battery recovery.

Intermittent faults hard to reproduce

Random resets, nuisance alarms, breakers tripping, or unexplained shutdowns.

Parasitic draw battery drain

Unexplained drain while docked or at anchor, leading to dead batteries.

Network problems NMEA 2000

Dropouts, missing devices, data errors, or power feed issues to the backbone.
