BOW PRO Boosted Series: BOWB
All the features of the phenomenal BOWA series with a bonus. All BOW PRO Boosted (BOWB) include an exclusive built in DC-to-DC smart charger function that allows 24 VDC thruster battery banks to be charged by a 12 VDC power supply and in the case of 48 VDC BOWB, to be charged from an existing 24 VDC power supply. BOWB thrusters do this through a third charge connection on the thruster. This charge connection is constantly monitored and is only activated once the voltage level of the charging source reaches a suitable level. This feature prevents the charging source from being depleted, such as the engine starting bank. They then boost that input to a higher voltage and regulate it in a smart way to charge the thruster supply bank. In practice, this means you are able to connect the 24 VDC BOW PRO Boosted with a 12 VDC power supply to charge its battery bank. The built in smart three stage charging process ensures that the thruster batteries are kept at their optimum level.
Connecting the BOW PRO Boosted directly to a 24 or 48 VDC power supply is also possible.
  • A range of thrusters with thrust outputs ranging from 57 Kgf to 320 Kgf
  • Battery powered at 24 VDC (or 48 VDC)
  • Runtime of 10 minutes at full power and even longer runtimes at reduced power • MCV motor controller with integrated boost charger 12/24 VDC (or 24/48 VDC)

RIMDRIVE Thrusters: RD125 and RD160
The RIMDRIVE is unique in its design; when operating, this thruster is extremely quiet! The propeller forms the rotating part of the electric motor (rotor) and the fixed winding (stator) is mounted in the tunnel. Therefore gears are not used in this design. Secondly a ring mounted around the propeller, prevents the propeller from cavitating. The RIMDRIVE is available in 125 and 160 kgf and needs a thruster supply voltage of 48 VDC. The panel should be ordered separately.
Unique features
  • Permanent magnet induction motor design, no carbon brushes
  • Quiet operation due to a virtually cavitation free propeller and no use of gears
  • Proportional control as standard via V-CAN
  • Runtime only limited by the supply bank
  • Easy to install
  • Maintenance free
  • IP67 top cover / ISO 8846 ignition protection compliant
  • Lock the thruster at any speed and hold the boat alongside the dock
  • Can be used as a stern thruster
  • Suitable for aluminum, steel and GRP boats
The RIMDRIVE from 2020 onwards will also be V-CAN controlled.

Ignition Protected DC bow and stern thrusters
Watertight and ignition protected motor housing In compartments with a gasoline/petrol engine, tank or fuel line, or propane gas storage, a thruster must be ignition protected to avoid the possibility of fumes or gas reaching the internal mechanism of the thruster and causing an explosion. All models come with the required seals, electrical connectors, fastening components and an automatic fuse which can be reset externally without having to open the housing. Furthermore the housing is an excellent protection against corrosion.
  • The housing enables thrusters to comply with ISO 8846 Marine ‘Ignition protection’ standard
  • Can be used as a stern thruster in combination with the appropriate kit
  • Supplied with all the required seals, electrical connectors and fastening components
  • Has an automatic fuse for the control loom that can be reset from the outside

 Retractable DC bow and stern thrusters
Want a thruster but your hull is too shallow for a tunnel thruster? Here’s the solution
For any thruster to work properly, the propeller and the tunnel in which it is mounted must be adequately submerged. Without this, the thruster will create a whirlpool at the water’s surface, on the suction side of the boat and pump a mixture of air and water, instead of all water, with a great reduction in thrust.
The minimum submersion of the top of the tunnel/tube/duct is considered to be half of the tunnel/duct/propeller diameter. As an example, the top of the tunnel for a thruster running in a 12” (300 mm) tunnel must be
at least 150 mm / 6” below the water. This applies equally to bow and stern thrusters. In addition, a bow thruster must be as far forward as the waterline and underwater profile of the boat will allow, and the stern thruster as far aft as possible, in both cases to create the maximum turning effect when the thruster is activated. If the design of the vessel is such
that these forward and aft thruster locations are in parts of the hull which are too shallow for a conventional athwartship tunnel or stern tube to
be adequately submerged, then the solution is to install a Retractable thruster.
A VETUS Retractable DC electric thruster is housed entirely inside the hull when not in use, but when sideways force is required for docking or maneuvering, the thruster swings down into the water, then retracts when docking and maneuvering operations are safely completed. These retractable thrusters may be used in bow and stern applications.

The VETUS retractable has some big advantages
  • The ability to equip a shallow draft boat, including a sailing boat with a cutaway forefoot and raised stern, with thrusters
  • Constructed around our standard VETUS DC thruster
  • A simple and sturdy swing mechanism, with a minimum of moving parts. The thruster pivots on a permanently lubricated and substantial bearing
  • The propeller revolves in a short duct, creating focused flow and minimum energy losses
  • The hull bottom plate (lid) is attached directly to the propeller duct so no additional or complex mechanism is required to open or close. It swings in and out with the thruster
  • When the thruster is retracted and the bottom plate closed, the retractable creates slightly less drag than a standard tunnel, which may be significant on a sailing boat
  • Fiberglass housing and electronic control mechanism (excl. the dashboard panel and cables) are supplied in the base package
  • The thrusters deploys and retracts automatically, as the control panel is deactivated, so no separate controls need to be operated
  • It will also retract automatically if the thruster has not been used for fifteen minutes
  • Electronic sensing protects the actuator of the swing mechanism from damage in event of an overload or jam
  • There is a one and a half second time delay when changing thrust direction to prevent shock loads on gears, drive mechanism and swing mechanism
  • The thruster(s) and their control panels are connected by cables carrying digital V-CAN signals (VETUS canbus type) allowing future integration into boat-wide electronic systems and information displays

VETUS Retractable Thrusters are suitable for installation in power and sailing boats ranging from 30 to 60 feet. They are available at thrust (effective power) ratings of 55 Kgf, 60 Kgf, 75 Kgf, 95 Kgf, 125 Kgf and 160 Kgf, at 12 VDC and 24 VDC.

VETUS strongly advices the use of original V-CAN connection cables to ensure optimal connection between controls and thruster.

Hydraulic bow and stern thrusters: BOW...HMD
These are the thrusters for the most demanding of work situations and are available in power outputs of 55 Kilograms Force (Kgf), 95 Kgf, 160 Kgf, 230 Kgf, 310 Kgf, 410 Kgf and 550 Kgf. They operate in hydraulics systems delivering flow rates ranging from 13 litres / 3.4 U.S gallons per minute to 91 litres / 24 U.S. gallons per minute, at pressures ranging from 165 bar/ 2393 p.s.i to 280 bar / 4061 p.s.i., all depending on thruster model selected.
VETUS hydraulic thrusters are able to run continuously, although not as primary propulsion units. They delivery high power and great reliability, with no electrical connections at the thruster or pump(s) and they need little routine maintenance. These thrusters are available with several control heads, in three control regimens, including proportional control.
The skill and knowledge set required to plan, integrate and implement a hydraulic installation work is extensive, and includes all of the skills required to install electric thrusters and a lot more. Such work should not be undertaken by persons, however generally experienced in boat work, who have not received formal training in power hydraulics theory and practice. Access to local hydraulic hose and fitting suppliers is also essential for a well-organized and successful installation.
If an existing hydraulic system can deliver the flow and allows the working pressure required by the thruster(s) appropriate for your vessel, it is often possible to add VETUS thrusters to the system, but VETUS also offers complete hydraulic systems as described in this catalog section.
Whether you buy a complete hydraulic system from VETUS, or just the thrusters, a VETUS customer support team member will review the entire system with you to ensure that your thrusters work according to our specifications after installation.
