Services
Marine electrical troubleshooting and onboard systems diagnostics for sailboats and powerboats. Emphasis on safety, reliability, and clarity of installation.
Services
Electrical Troubleshooting
Intermittent faults, dead circuits, breaker trips, voltage drop, parasitic drain, and corrosion-related failures.
Charging & Battery Systems
Alternators, regulators, shore chargers, DC-DC charging, battery banks, and charging performance verification.
Lithium Battery Conversions
LiFePO4 system design, charging source compatibility, BMS integration, alternator protection, and conversion from lead-acid with proper system verification.
Shore Power & AC Systems
Inlet and distribution faults, nuisance trips, GFCI and galvanic protection verification, and grounding and bonding evaluation.
Corrosion & Stray Current Diagnostics
Hull potential measurement, stray current testing, galvanic isolator verification, and bonding system evaluation using a silver/silver chloride reference electrode.
Power Quality Analysis
Shore power voltage and frequency verification, harmonic distortion, voltage drop under load, and identification of power quality issues affecting sensitive electronics and charging systems.
Thermal Imaging
Infrared inspection of panels, connections, and wiring under load. Identifies hot spots, failing terminations, and overloaded circuits before they become failures.
NMEA 2000 & Electronics
Backbone power issues, terminations, topology errors, device dropouts, and network voltage verification.
Bilge & Critical Circuits
Bilge pumps, float switches, alarms, auto/manual logic, feed integrity, and corrective wiring work.
Wiring Cleanup & Documentation
Circuit tracing, labeling, termination upgrades, routing improvements, and correction of unsafe modifications.
System Mapping
Panel circuit index, battery and charging path documentation, shore power path, and annotated photo set delivered as a PDF.
Communications & Navigation Systems
VHF, AIS, SSB, and GPS antenna system testing, feedline integrity, radio installation and verification, chartplotter integration, and diagnosis of range or performance issues.
Rates
Diagnostic Session initial
$400 flat — up to 2 hours on site. Includes measurements, fault isolation, and a findings summary.
Service & Corrective Work hourly
$160 per hour. Corrective work, upgrades, system consulting, and troubleshooting beyond the initial session.
System Mapping documentation
Starting at $750 depending on vessel size and complexity. Includes a panel circuit index, battery and charging path, shore power path, annotated photos, and a PDF deliverable.
Electrical Condition Report documentation
Formal written assessment of onboard electrical system condition. Useful for insurance documentation, vessel sale, or establishing a baseline before refit. Delivered as a PDF. Priced per engagement depending on vessel complexity.
Starting at $350
Travel within the central San Francisco Bay Area is included. Extended travel may be billed separately.
Electrical Watchkeeping
A scheduled monthly or biweekly visit covering shore power status, battery voltage, bilge pump and float switch operation, charging system condition, and visible wiring or corrosion concerns. After each visit you'll receive a written condition report and photo documentation.
Monthly 1× / month
Shore power status, battery voltage, bilge pump and float switch verification, visible leaks and water intrusion, dock lines and chafe inspection.
$125 / month
Biweekly 2× / month
Same scope as monthly. Recommended for higher-risk vessels or extended owner absence.
$200 / month
Storm / Heavy Weather per visit
Post-weather check for lines and chafe, water intrusion, shore power status, and bilge condition.
$75 / visit
Seasonal Check one-time
Single visit at the start or end of season. Shore power, battery condition, bilge systems, and general electrical status — with a written report delivered after the visit.
$150 / visit
Watchkeeping visits are condition monitoring and do not replace required maintenance, surveys, or mechanical repairs. Corrective work is scheduled and billed separately.
Scheduling
Provide marina location, description of the issue, and photos of affected areas when reaching out. Phone, text, or email all work.
