48V Wiring Installation

This time on Distant Shores we do a deep dive into the 48V wiring system - check out the installation … and see why we think it's worth moving up from a traditional 12 Volt system.

Shore Power - This may shock you

If you could install one single device on your sailboat that would make your boat shockproof for swimmers, prevent galvanic corrosion and also stop any worries about reversed shore-power polarity would you want one? That device would be an isolation transformer and we're going to talk about that today as we talk about shore power connections and electrical systems on sailboats.

Safe Lithium Batteries for Sailboat

This time on Distant Shores we go into depth on Lithium batteries, planning out the boat's energy storage system, and touring the Super-B Battery factory where we learn how marine lithium batteries are manufactured and tested for safety.

HYBRID Power Sailboat - Will it Work for Long Distance Cruising?

This time on Distant Shores we're planning out the energy requirements of our new Enksail Orion 49 custom aluminum sailboat. Will a hybrid power system allow us to achieve the passages we're planning from Europe to the Arctic Circle as well as long ocean passages around the world? We examine our power usage from past voyages made on previous boats and talk to the crew of S/V Delos about their experiences with electric cooking.

Hybrid Power on a Sailboat – Offshore Livestream using Starlink!

This time on Distant Shores we discuss the pros and cons of using a hybrid drive on a sailboat with former SpaceX engineer and sailor, Casey Schilling. We record a video conference with him while he’s 50 miles offshore using Starlink! Check out the results and learn how hybrid drives work too.

Lithium Battery Install

When the AGM batteries fail on our Southerly 480 sailboat following months of lockdown in Panama, we take the opportunity to replace them with lithium batteries before selling the boat. (We're designing a new custom aluminum sailboat.) With crocodiles in the water around the boat at the dock in Shelter Bay Marina, Paul builds a new battery box and friends help lift the new batteries into place. Paul completes the installation and we set sail for a test cruise to the San Blas Islands.

Hydrogen-Electric power on boats

We're building a new boat and looking into various propulsion systems including the possibility of an electric drive.
In Panama we meet the Energy Observer which is travelling around the world demonstrating the possibilities of hydrogen fuel. They are powering all ships systems, including cooking, navigation and even powering the electric motors that drive her through the water with electricity. The electricity is collected in her solar panels which cover every bit of her wide decks. The power is stored in batteries, and also in compressed hydrogen. It's the hydrogen that makes her so interesting.

Energy Observer carries 62 kilograms of hydrogen fuel in carbon fibre wound tanks. This can be run through their fuel cell to produce some 800kwh of electricity. Their solar-panel covered decks produce 31kW peak output which is stored in Lithium batteries of 100kW. And when they have surplus power from the sun they can even produce their own hydrogen to refill the tanks. Add in automatically controlled sails for additional speed. They are doing a promotional world tour showcasing this 100% self-contained no-carbon voyage.

Check out the Energy Observer homepage for more information and to follow their voyage.

Electromagnetic Pulse - EMP

What if lightning strikes near your boat?

Back on board Distant Shores III in Panama, we discover some of the equipment at the top of the mast isn’t working due to a "lightning event" called an electromagnetic pulse. We demonstrate our system for going aloft to remove the gear, then reminisce about Christmas and New Year celebrations in countries we’ve sailed to in years past.

Battery Problems - Time for Lithium!

We finally get back to our boat in Panama after 7 months of lockdown and at first glance everything seems fine. Then we start going through lockers and systems thoroughly and problems start rearing their ugly heads. The biggest is that our 48 volt battery bank is dead! Time to replace with lithium. Then Hurricane Iota passes bringing stormy weather. Sheryl shows you our galley storage methods. The two Pauls discuss the Pandemic and the History of Yellow Fever in Panama.

Understanding Marine Power Systems

Do you want to understand marine power systems better? Do you find marine power systems confusing? Are you trying to determine if your boat has enough power to run the equipment you’d like to install?
In this video series, we take you aboard our Southerly 480 sailboat, Distant Shores III, to help you understand what is involved in setting up a marine power system for your own boat.

Part 1 - Electrical Basics


In Part 1 of this new video series, we take you aboard our new Southerly 480, Distant Shores III, and start with the basics to help you understand what is involved in setting up a marine power system for your own boat.

Part 2 - Power Budgeting


In Part 2 of this video series, we create an electrical budget calculating our power use for various devices.

Part 3 - Solar Power & Generator on Distant Shores III


In this episode, we demonstrate our solar power system and Integrel on-engine generator and discuss how we use them together.
