Waterworld electrification of a classic Dutch barge
On October 9, 2024, we were approached by an old acquaintance with a request that led to the Waterworld electrification of a beautiful classic Dutch barge. Because of our history with both the owner and the boat itself, this turned out to be a truly wonderful project. The owner decided to do much of the work himself, and the end result is something everyone involved can be proud of. First, let's introduce the boat.
The family ship Molenaar
The photo shows Marco Molenaar of Molenaar Jachtbouw in Woubrugge. We met Marco in 2019 when we began the complete rebuilding of our own cabin catamaran . We carried out this restoration entirely at Molenaar Jachtbouw , with Marco's assistance. Without his help and the facilities he provided, it would never have been possible, and Robust-MT Marine Technology BV never have been established.
The boat in question belonged to his father and has always remained in the family. At least, until two years ago. Just as we were finishing our restoration, the boat was purchased by Peter and his young family. We witnessed firsthand how Peter, his partner, and his children got the boat sailing again, and we got to know them as avid water sports enthusiasts and incredibly friendly people. Peter, incidentally, turned out to be a doctor; more on that later.
Rescuer in need
At one point, I was working in the boat and suddenly had to go outside—I don't remember why. What I do know is that at that moment, I'd forgotten that there were some clamps in the boat's doorway holding a bulkhead in place. They were secure because I couldn't knock them off with my head. The result was a bloody shirt and a large open wound on my head. Luckily, Peter was nearby and was able to temporarily stitch the wound on the spot, allowing me to finish the day's work.
So, Peter approached us on October 9th, not knowing who we were, but on Marco's advice, asking if we could electrify the boat. The fun was complete when we recognized the boat, and Peter then recognized us. After some phone calls, chats, and a pleasant evening visit to our office, we reached a decision. The gasoline engine would be replaced with a beautiful Waterworld 4kW inboard motor, more than sufficient for this boat.
Waterworld built-in electric hood
Over the winter months, the old engine was removed, the engine compartment thoroughly cleaned, repainted, and prepared for the new engine. It fit perfectly and, even with the battery, takes up less space than the old engine without the fuel tank. Ultimately, we decided to build a fixed platform above the engine and mount the battery there. Our work consisted primarily of custom wiring and testing. We also installed a 220V network (shore power supply) and prepared a switch panel with a USB charger and battery monitor. Peter did most of the rest himself.
The boat has been in the water since this week, and Peter has already completed his first test run. How did it go? We'll let Peter do the talking:
