The onboard ground fault issue can be resolved through proper installation of an isolation transformer. Unfortunately, that option is not practical for most cruisers due to cost and space requirements. If your boat has 50A/220V AC shorepower and does not have an isolation transformer, now would be a good time. For everyone else we can expect a few more years of transition as the industry responds to evolving codes and standards. If you have not run into this problem yet and have a trip planned, consider hiring a marine electrician to give your boat a shorepower health check. The money will be well spent, resulting in a safer boat and one that can travel and still find access to shorepower.
