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

 Sails

  • 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.

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.

    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.

    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.

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

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?
