Plugging In

It is easy to become complacent when it comes to plugging an electrical cord into a socket. This convenient arrangement for making an electrical connection has become such a casual part of our lives. It is commonplace to just plug-in if it fits and sometimes, with a little encouragement, it can be made to fit.

Best Boat Heater Systems for Cruising Boats

A little heat can go a long way towards extending and enjoying boating into the shoulder seasons when the weather gets cooler and damper. A properly installed marine heater can provide that luxury, but not all heating sources are the same.

Garmin's Product Updates

We recently attended a Garmin training course and thought we would share some of the things we learned. Some we knew and some are new. For 2016, the Garmin GPSMAP 76XX series chartplotters will include the full Western Canada G2 charts. Up until now, only the USA...

Importance of Remote Battery Switches

A common conundrum with battery banks and their main disconnect switch is that batteries are often located in the engine room space. The cable to disconnect switch for the battery should be as short as possible and by commonly accepted standards, within 72” from the battery terminal post. The problem arises that in the situation of a catastrophic event, like a battery exploding, it should be possible to easily access and disconnect the battery without entering the space in which the battery is contained.

Shore Power Connections

With the coming of fall and cooler weather, there will inevitably be some concerned boat owners having a closer look at their shore power connections. Many boats will soon, if they are not already, be tied to the dock for the duration of the ‘off-season’ with the exception of possibly a couple of forays on spectacular or special days. Most people will leave their AC electrical system connected to the shore side utility to run the battery charger and maintain the batteries

Firefly Oasis: A Comparison with Lead-Acid and AGM Batteries

Lead/acid batteries are by far the most prevalent form of stored power, even though battery technology is constantly developing newer formats and improving the current on the formats that are already on the market. The reason that lead/acid batteries still prevail are that the dollar per power ratio is very favorable. The energy density of...

Battery Voltage vs Battery Capacity

The best way to determine remaining battery capacity is by using a self-learning battery monitor with a percentage state of charge function (SOC). However, not every boat is equipped with that type of device nor does every boat owner have such a device in their budget. If the only means of estimating remaining battery capacity is a voltage meter, then a reasonable approximation can be made based on an accurate digital voltage measurement with a battery utilizing lead/acid chemistry.

Advantages of External Alternator Regulation

Alternator regulators were traditionally built into or attached to the back of the alternator and were functionally either producing power or were not producing power. This approach is fine for many applications, particularly with power boats that run their engine, and therefore the alternator for long periods of time. For other vessel operators the engine run times maybe shorter.

Direct Methanol Fuel Cell

You can never have too many options for alternative energy charging choices for the DC system on a boat. Direct Methanol Fuel Cells are an interesting alternative that is worth considering.

Peukert’s Law

It is important when managing a battery bank that you know the bank’s capacity. Batteries and battery bank capacities are usually determined from information provided by the battery manufacturer. A common rating for storage batteries is 20 hour rate.
