Our friends over at Hubbell have just introduced an inexpensive solution for older boats not equipped with ELCI devices to shut down the shore power to a boat that has some excessive ground fault leakage issues on board. Although this new circuit checker won’t actually shut anything down, and it doesn’t specifically identify ground faults from equipment installed on board, Continue Reading »

Yanmar Provides LION Battery Bulletin

Yanmar Provides LION Battery Bulletin

It seems that our friends at Yanmar may have been having some issues with some customers swapping out the batteries on their boats for lithium ion units. It is imperative to note that there is a LOT more to do with your boat when switching to lithium technology than merely swapping out the batteries. A proper BMS (battery management system) Continue Reading »

Electrical System Breakthrough for Boats

Magnum Energy has just announced what I consider to be a major step forward for small boat electrical systems. The MagnaSine hybrid inverter/charger is a pure sine wave inverter that also integrates the ability to provide supplemental AC power when needed on board. I see this as particularly useful feature on boats using smaller AC gensets either due to weight Continue Reading »

Stop Saildrive Corrosion

Stop Saildrive Corrosion

I recently penned an article for the June/July 2017 issue of Cruising World magazine entitled “Driven to Diligence“. The article discusses the growth in market share for sail drives in cruising sailboats  as well as some of the issues relative to their maintenance and health. If you own a boat with a sail drive or two installed, I highly recommend Continue Reading »

New Hubbell Shore Power Y-Adaptor Solves a Common Problem

    What boater hasn’t faced the problem of pulling into a new marina for the night, to find it only offers 30A power when the boat runs on 50A? The YQ230 Intelligent Y-Adapter from Hubbell Marine gives owners the freedom to travel without concern. It allows them to safely connect any 50A, 125/250V AC marine cord set to two Continue Reading »

Electromagnetic Interference On Your Boat

Electromagnetic Interference On Your Boat

Electromagnetic Interference (a.k.a Crosstalk ) As mentioned earlier this month I’m sharing some of the points brought out when I attended the new ABYC/NMEA joint training program offered in Ft. Lauderdale, FL. One of the topics that came up during the NMEA portion of the program discussed electromagnetic interference. This is a topic that I know I’ve discussed here before. But, Continue Reading »

Are Your Boat’s Electrical Terminations Compliant with World Wide Standards?

Are Your Boat’s Electrical Terminations Compliant with World Wide Standards?

Recently I’ve been wondering about one of the more common wiring schemes that I see on both power and sailboats, primarily made outside of the US but certainly quite popular here in the US. The DIN rail mounted terminal strips you see here in my lead photo illustrate what has me wondering what’s up. These terminal configurations come in a Continue Reading »

More OnElectric Shock Drowning (ESD)

I received a query recently from a person who read a recent article in Boating Magazine entitled “Stop the Shock”. At the suggestion of Boating’s  editor Kevin Falvey I thought I might take a few moments to answer the readers fundamental question, why don’t we need to worry about in water shock hazard when unplugged from the dock and anchored Continue Reading »
