Live Your Dream. Sail around the world.

Systems and Components of an Offshore Sailing Catamaran

After three and a half years of sailing around the world and well over 10000 nautical miles we wanted to give you a tour of our floating home as it is now. Nahoa is a 2005 Lagoon 410 owner’s version that has carried us all this way. We have worked hard over these last years to set her up for long term offshore cruising. While there is always a project list and a wish list (new high output alternators, spinnaker, new Genoa), we are very happy with our current setup and wanted to share it with you.

Our longest video to date includes a high level view of our main power, navigation and safety systems that enable us to live life off the grid. Don’t worry you also get a detailed tour of the inside of our boat and the comforts that keep us happily sailing around the world!

Nahoa has had a huge remodel since we purchased her in 2015. We have done 2 refits to get her setup for comfort and to solve our power requirements. If you want to check out the before of Nahoa you can watch our first walkthrough video here. Notice all the beautiful green has been replaced? Well that isn’t all! Below we have a list of some of the main components we have added or replaced. This list does not include basic maintenance items since those are essentially relentless. It does however cover some of the bigger items which were replaced as they broke and wore out. We have found that in the last year, as the boat turned 12-13 years old, we have had to replace more of the remaining systems. Also the previous owner had replaced standing rigging and so that is something we have not had to yet tackle, but it will come up again soon! So without further rambling, if you are curious please check the exhaustive list below and I hope you enjoy the tour. 

Nahoa Full Equipment List


  • Triangular cruising mainsail with 3 reefs (new 2018). A short word on mainsails with a lot of roach (the large sail area at the very top). We often find ourselves sailing in 18+ knots here in trade wind territory. At 20 knots we put the first reef in. Although square top mainsails are very popular and look sexy, we find a triangular mainsail much more practical as it is rare we have too much cloth up.

Dear nahoa. Following you all for months. I beg you. Please research vaccine especially now that your pregnant. Research. Not approved. Research
Love you all.

Hi who did you use to reconfigure the island seat in the saloon? We would love to get rid of the seat back. Cheers Michelle

What solar panels do you use?

Awesome sailing channel – great to see how you are able to manage your vessel and conditions and are able to navigate across the planet!
I did have one maintenance question – do your saildrives require you haul often for service?

Hello, can you list the make/model of your solar panels? Are you satisfied with their performance?
Thank you!

Hi guys! Been a sub on you tube for awhile…now I’m your newest Admiral supporter on Patreon. Thank you so much for this systems and components vid! It totally solidified my approach in how I will be doing this! Of course love the other stuff too, but especially love the technical aspect of how you guys think. It’s very very close to how I want to rig my boat! Same amenities, same overall equipment, same preparation. Keep going and be safe! Thanks!

Hi, love the videos.

What type is the air compressor for scuba.



    January 7, 2019

    Hey Stern. We bought a very used Colitri sub. Gas powered. Fills our tanks in about 20 minutes. Very loud but we could probably replace the muffler and make it a bunch quieter.

I see that you have 2 300Ah relion lithium iron phosphate batteries and also a flooded starter battery.
What is the blue controller they are wired through?
Also, do you charge the lithium from the engine alternator as well as wind and solar?
I would love to learn more about the details of your charging system.
Thanks, Russ

Hello! Love following you guys! Could you do an episode or give us a highlight into what equipment you use to make videos? Thank you!


November 16, 2018

Fantastic video, love the details. Thanks. How do you run the Washing Machine without a generator?

Do you feel that 260 liters of fuel is optimum, would you like to have bigger diesel tanks?

Great, practical video Can you explain exactly the process for using Bing and Google Earth photos to navigate? I have a B and G Zeus chart plotter and TimeZero on a laptop for back up.


    September 17, 2018

    Thanks Walter. Absolutely. For satellite navigation we use two systems. First an app on the iPad called Ovital Map. You can find it in the Apple Appstore. Make sure to check both the Bing and Google layers (button in the top right). We’ve found the Bing layer often shows more stuff under the water. Second, we use satellite KAP files in OpenCPN on a Macbook.

Really enjoyed this video! We have just begun our adventure onboard our Dean 441 cat. I think that most of our systems are very similar. A bit jealous of that washing machine though…. I did want to let you know that when you need new sails, the guys at Ullman Sails South Africa (Cape Town) did a fantastic job for us. We recently did a huge refit of standing rigging and sails. Like you, I can’t say enough about our code zero. Fair winds and we will keep watching when we get internet every now and again.


    September 17, 2018

    Hi Jason. Congratulations on beginning your adventure. That’s exciting times! We got our mainsail from Ullman South Africa and didn’t have the best experience as they were very unresponsive. But many others have good stuff to say about them so we’re just one data point. Thanks for commenting.

Can you list the make/model of your washing machine. Thanks!


    September 17, 2018

    The washing machine is an Electrolux 7.5KG. Model EWF12753. Picked it up in New Zealand on a boxing day say for crazy cheap.


September 15, 2018

Ah, we indeed forgot to cover that one. In two ways. The hot water tank is connected to the starboard cooling system. When the engine is running, it will heat the water. Alternatively, when we are plugged into shore power at a dock, we can flip the breaker to turn on the hot water heater. We find hot water lasts us about 2 days out here in the tropics (without running the engine). In New Zealand we needed to run the engine every day but only takes about 20 minutes to heat up.

How do you make hot water?
