The Offshore Voyaging Reference Site
A comparison of the two regulators cutting through all the details to what really matters, and including a look at how to evaluate all tech products.
An honest evaluation from a thinking guy, who carefully evaluated his usage before pulling the trigger on an expensive piece of gear, not a fan-boy video.
Two fixes many production and new-to-us boats will need to make the high-voltage shore power system safe.
We often see cruisers using a portable gas generator to feed their boat’s shore power, but is that safe?
Shore power safety is something most of us don’t think about much, but here’s why we should, based on a scary real world experience, and some checks we should all make.
These days we are seeing some great new battery technologies for a live-aboard voyaging boat, but with that we are also seeing some wild claims. It’s important not to let our enthusiasm for the former blind us to the latter.
We are increasingly hearing about induction cooking on boats being the next big thing, and green, too. But what are the real numbers? John takes real world measurements and a deep dive into the results.
John takes an in-depth look at the benefits and drawbacks of carbon foam, liquid filled, and AGM lead acid batteries, and then reveals his thinking if faced with battery replacement today.
Are you considering a hydro generator? Here’s everything you need to know, warts and all, from an experienced user.
The claims made for battery pulse desulphators seem to make them ideal for voyaging boats. A cheap, easy to install gadget that will dramatically extend your expensive batteries’ lives. What’s not to like? But do they really work? John takes a look.
The story of how John nearly wasted a bunch of time and money, but finally got a grip of himself. Lots of electrical system recommendations and a caution to make sure that the complexity we choose is right for us.
John’s in rant mode. This time it’s marine electronic and electrical technician training that has attracted his ire. But he’s not just throwing rocks, he makes suggestions for improvement too.
After voyaging and living aboard their Ovni 435 for 7 years, Colin gives us an update on what electrical kit has worked and what has died, as well as a look at newly available gear he and Louise have installed or are considering.
Do you need a diesel generator to go cruising? It’s a surprisingly simple decision governed by only two criteria.
Matt examines lithium ion batteries in detail and answers the question, Should I use lithium ion batteries for the house bank on my boat?
Matt, AAC Technical correspondent, takes a look at an intriguing new technology that holds a lot of promise for cruising boats. But before we all rush to wire our boats this way, there are some questions that the vendors need to answer.
Developments in alternative energy systems are coming thick and fast these days, so Colin visited the Southampton Boat Show and has filed this report on the latest in fuel cells, solar panels, and hydro-generators.
Meeting daily electricity needs using power and solar while at anchor is one thing, but what about when passagemaking? Solar can only do so much and wind generation works best when sailing to windward. So is hydro the answer? Colin talks about the pros and cons of hydro generation.
Let’s face it, there is never enough time to keep a boat that is actively out there voyaging in perfect condition: Or at least, there is never enough time if we actually want to see the places we visit and have a life outside of boat maintenance. Therefore, we have to prioritize and be careful […]
Question: Due to space considerations I want to use two 105 amp hour and two 150 amp hour batteries as a house battery bank. Would this arrangement be detrimental to the smaller batteries?
Combined inverters and chargers have become pretty much standard on cruising sailboats but, in fact, that’s a really bad idea. In this chapter we will share why and what to do about it.
Readers of my previous post on the subject will be aware that we try to generate as much power as possible via renewable resources – wind and solar. This is driven by a desire to keep the boat as simple as possible, and to avoid the need to run our engine at rest for charging […]
