A. van der Wal: Tuna 38

Mr A. van der Wal and his wife have over sixty years of water sport experience, mainly with sailing yachts and, since 2004, with a motor yacht, the Tuna 38. In 2011 he had Karyvo install a Jet Thruster JT-50 into the stern, equipped with two 90º nozzles. "Because we mainly sailed together, and since the Tuna is rather wide, we required another system, in addition to the existing bow thruster. We are very pleased with the system. Combined with the bow thruster it works very well when mooring and sailing away.

It adds to the manoeuvrability of the vessel." Due to our ceasing our water sport activities we have now sold the Tuna. What remains are sixty years of good memories to water sports.

Ralph Berkmans: Grand Banks 42 Europa

Ralph Berkmans owns Breskens Yacht Service. This company has a summer & winter storage depot (8000 m² indoors) and is equipped for every conceivable maintenance activity, up to and including complete refits. In addition to recreational boating, Breskens Yacht Service also serves commercial shipping. For one of his own clients, Ralph has installed a JT-90 in the stern of a Grand Banks 42 Europa. Typical for this 13-metre ship is the fly-bridge. The Grand Banks therefore has double controls. Ralph: "There was already a bow thruster installed in the vessel. In conjunction with the JT-90 the ship has optimum manoeuvrability. Installation is relatively simple, even though the JT-90's pump is fairly large. Some improvisation was required, because the JT-90 works on 24 volts, while the vessel is equipped with a 12-volt system. But we sorted all of that out. Due to the double controls I came up with a system that makes it possible to control the bow thruster and the Jet Thruster at the same time on both levels. This works perfectly. It is also true for the Jet Thruster itself; this system is powerful enough. The system's purchase and installation requires a considerable investment, but I do think it is a fine system that is simple to install. After this first installation experience we, Breskens Yacht Service, have registered with Holland Marine Parts to become a Jet Thruster dealer."

"Scratches on mahogany, you don't want that"

Charlie van der Veer:
The design of a Rapsody 29 OC is similar to a 1932 Petterson. Charlie van der Veer is the owner of this fine massive 2000 mahogany Rapsody. He leaves no doubt: "Scratches on mahogany, you don't want that. Such a scratch gets dark. If it gets lighter you can darken it, but the other way around doesn't work. That's why in 2008 I had Karst Braaksma from Karyvo in Sneek, the Netherlands, install the Jet Thruster's predecessor as an addition to the existing bow thruster. A good system, in principle, but the complicated electronics were sensitive to interference and in 2012 the valve turned out to be completely stuck. Karst then rebuilt the valve and control system to the level of the current Jet Thruster, and now it all works to my full satisfaction. I chose the Jet Thruster because the system works so silently. This is a major advantage compared to the propeller. The control system with two joy sticks on the dashboard make the system very easy to control, also in combination with the bow thruster. Moving sideways or rotating around the axis in a narrow channel – you can do it all. Noisy in front and silent in the back, but at least no scratches!"
