EP42 - Prepping the battery compartment to receive 55wh battery bank

Before we can install our new 55 watt hour LiFePo battery bank, the space needs some serious work. From ensuring a dry space, to sanding, fiberglass, and paint, this space has been transformed into a perfect home for our LiFePo batteries.

EP40 - DIY major maintenance on two YANMAR 4JH4-TE 75hp's - Part 1

We have two Yanmar 4JH4-TE 75hp engines. With regular maintenance, these engines should comfortably last 10,000hrs and ours have 5,000. Engine maintenance is difficult on a boat. Space is tight, temperatures are often unbearable, and unless you have confidence and experience working on engines, it’s not uncommon

EP39 - Winter Preparation - climate controlled storage and shop lights.

We weren't planning to be here this long. The seasons are changing quickly and with it comes cold temperatures and short days. Everything we own is in two storage containers that are little more than metal boxes. These will certainly have plenty of condensation during the cold months

EP37 DIY lithium batteries can save you thousands! Part 1

One of the biggest and costliest project in many yacht refits is new batteries. These days, most battery changes are by people moving from standard AGMs to Lithium, or making the change to a higher native voltage from 12v to 24v or 48v. We are making the change to a

Ep36 Racing the change of season to prep the mast for paint.

We removed every piece of hardware from the mast and boom and discovered a lot of peeled and bubbling paint. That can only mean one thing...corrosion. We wanted a better look at the aluminum, so we decided to completely strip and repaint both mast and boom. Weeks of sanding

EP35 - Badly aged caulk is causing leaks!

Months after hauling our 54' catamaran out of the water to begin the refit, we finally did something that will stay on the boat. Many projects are in process, but that's been the name of the game for a long time. We were both itching to move

Ep34 - See what happens WITHOUT Tef-Gel on your rigging hardware

The mast, boom, and davits we removed shortly after we hauled ROAM out of the water. They have been sitting on foam blocks since then waiting to reach the top of the priority list. Our rigging makeover is a multi step process that starts now. The first step is to

Ep33 The engine rooms get prepared for a makeover

We are finally moving forward on our refit. This is the first time we're doing work that actually moves the project forward, rather than tearing stuff apart. The engine rooms are going to get a face lift, but before we can proceed they need to be cleaned, sanded,
