What is marine shore power?

Marine shore power provides AC electricity from the dock to your boat using a shore power cord and inlet. It allows you to run onboard systems, charge batteries, and power appliances safely while docked.

What’s the difference between 30 amp and 50 amp shore power cords?

A 30 amp shore power cord delivers 120V AC, ideal for smaller boats. A 50 amp cord provides dual 120V legs (240V total), used for larger vessels with multiple air conditioners or high-load systems.

Are all marine shore power cords waterproof?

Marine shore power cords from brands like Marinco and SmartPlug are fully waterproof, UV-resistant, and built with corrosion-resistant contacts for long-term durability in saltwater environments.

Do I need a galvanic isolator for shore power?

Yes. A galvanic isolator protects your boat from stray electrical currents that cause corrosion when connected to dock power for extended periods.
