EXTERNAL BOW & STERN THRUSTER
Most innovative technology for perfect, easy and safe manoeuvring, EXTURN bow and stern thruster - the lastest development in manoeuvring-assistance - stands for easiest possible installation, ideal efficiency, no needed space inside the boat hull, minimum noise and unbeatable runtime. Tested by the international technical press.
The EXTURN bow and stern thruster is mountable onto nearly any boat of size between 6 and 20 m independently of hull shape, type of drive and draught:
| |
|
sailboats |
|
|
motorboats |
|
|
houseboats |
|
|
catamarans |
EXTURN is offered in 6 different power levels to ensure the ideal solution for any boat type and size within this bandwidth. Essential parameters for the right power level choice are boat length, boat weight, hull shape, freeboard, operational area (coast or inland waters) and wind force. |

Advantages of EXTURN
The unique MARINNO bow and stern thruster technology EXTURN offers the boat owner significant advantages: |
1. |
Optimal efficiency
Due to its installation at the foremost or sternmost spot of the boat hull and the signifi cantly lower position under water in comparison to conventional thruster systems, an optimal leverage is achieved. Therefore EXTURN moves much bigger boats than traditional thrusters with nominal lesser power. Furthermore due to the optimal leverage the boat responses considerably faster. Also see the illustration under Efficiency and the video of the efficiency-test performed in the flow test channel. |
2. |
Simple installation
For the installation of EXTURN it is merely necessary to drill a hole of 50 mm in diameter through the hull for the threaded bolt which serves as the cable run. This bolt is supplied with a special pressure-tight sealing which closes the drilled hole automatically and eliminates the need of GRP work.The included mounting kit is fixed with screws including pressure-tight sealings and gives EXTURN the required stability. |
3. |
No space inside
Except of the relay and the cable run the bow or stern thruster requires no space in the boat interior. |
4. |
Minimal noise
Due to the positioning outside the hull, the therefore minimization of cavitation and the usage of rubber pads on all fastening elements, EXTURN has much less noise emission than conventional thruster systems. |
5. |
Longer runtime
The shift of the motor to the outside and the water cooling provide EXTURN with a much longer runtime per hour than conventional thruster systems. Depending on water temperature the continuous runtime is 4 minutes, however after required short cooling intermissions up to 25 minutes per hour! |
6. |
also the ideal solution for wooden boats and houseboats
Due to the elimination of GRP work, EXTURN is also the ideal solution to make wooden boats or houseboats easier maneuverable. |
7. |
full guarantee of 3 years
EXTURN stands for outstanding quality, from thruster unit to the electrical components, and is absolutely maintenance-free. Therefore we are offering 3 years of full guarantee. |
