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!"

Marco: Ventura 8.5

Marco is the owner-manager of Ventura B.V., a Dutch manufacturer, located in Geertruidenberg, of handcrafted wooden speed boats with a beautiful interplay of lines evoking nostalgic memories. But anyone who looks twice will see that Venturas have a timeless design. A stylish speed boat, always equipped with a powerful engine. Marco himself has installed a JT-30 in the bow of a Ventura 8.5, which stands for 8.5 metres in length: "The installation was fairly easily done. With the right holesaw for the nozzles and an epoxy treatment it is simple to make it watertight. It is, however, useful to have someone help you, I noticed. I placed the pump in the stern, because I had room there. I have to admit, the Jet Thruster is a unique product. Compared to a bow thruster the Jet Thruster makes hardly any sound at all, and the system is easily and intuitively controlled with the joy stick. It is just a matter of pushing the stick in the direction you want to move. All things considered I love the system. It is extremely useful in the harbour, especially when you want to moor at a narrow berth. Because the Ventura is a luxuriously equipped speed boat, I plan on installing a Jet Thruster in all new vessels we make – a unique system for a unique speed boat."

Bart Heemskerk:

The sloops of Jan van Gent from Aalsmeer, the Netherlands: almost everyone knows these fine vessels. They are quality sloops to relax in, but, thanks to their powerful motor, they are also suitable for sailing 45 kph. Owner Bart Heemskerk: "We make high demands for our products and the components were use. When you order one of our sloops, you always get a very complete package at no additional cost. We supply the Jet Thruster JT-50 Dual as an ex works option. We recommend the Dual, since, in view of the necessary investment and compared to the surplus costs, it is better to install the system in the bow and stern both. At this moment 25 per cent of the 10.35 Jan van Gent sloops ordered are equipped with the Jet Thruster system. Installing it in a sloop which has seen previous use is theoretically among the possibilities, but in such a case the installation costs are relatively high. The performance is fine, but you do need a JT-50. This is also to do with the deep trim of the heel. Quite a bit of water needs to be moved there. The Dual ensures that the system is optimally suited for the Jan van Gent. Our clients tell us they are happy with the system's silent operation, because it guarantees that when mooring at an outdoor café you don't draw too much attention with your bow thruster, which invariably makes the sound of a coffee grinder."

Hans Webbink: Bronson 36 Islander

Hans Webbink, owner of Steel Yachts in Steenwijk, the Netherlands, talks about the Bronson 36 Islander, a very exceptional 10.55-metre tender. The tender, manufactured from lightweight aluminium, comes with every conceivable luxury. But the main attraction has to be the back, which unfolds into a giant deck. By anchoring or using spud poles we can create an island. Truly special. He says: "For optimal manoeuvring, in the early development stage we opted for a bow thruster in the bow and a JT-50 in the stern. Both systems perform excellently, but the difference in sound is tremendous. If you first start the Jet Thruster and then the bow thruster, the difference in sound is like the Beauty and the Beast. The Bronson 36 Island, now available for order, is fully custom made, save for the collapsible side panels. Our clients can therefore choose themselves what they do and do not want - the possibilities are endless. However, we will recommend our clients to install a Jet Thruster in the bow and stern. In closing, I cannot refrain from saying that with this tender we have been nominated for the title of European Motorboat of the Year!"
