MARINNO´s “EXTURN” for simple maneuvering
Compact, practical, high-performance. MARINNO’s external bow and stern thruster “EXTURN” – an innovation combining functionality and luxury beyond any comparison.
A well-known problem
Since ever, bow thrusters have been a practical and popular steering aid to facilitate maneuvering in narrow ports or under difficult conditions. The purchase of a bow thruster, however, is mostly connected with substantial expenditure and numerous disadvantages. How much space is needed in the interior of the ship? What assembly work and costs to expect? How long is the downtime of the boat while the bow thruster is
being installed? Does the boat have the necessary hull shape to install a bow thruster at all? These are only some of the questions which often lead to only one answer: The boat owner decides against the installation of a bow thruster. Up to now. Because the Austrian enterprise “MARINNO maritime innovations” specialized in innovative boat equipment, offers a simple, economical alternative for more safety and comfort: EXTURN – The
external bow and stern thruster.
External bow and stern thruster EXTURN
The term “external bow and stern thruster” already suggests the fundamental advantages of this new
technology. The complete thruster mechanism was reduced to a minimum size and moved to the outside;
ideally streamlined. Instead of – as before – putting a transverse channel in the bow of the ship, which is cost-intensive and takes up much room, the EXTURN thruster is mounted by one threaded bolt which is designed as a hollow shaft and serves as the cable run. An enclosed mounting kit for any kind of hull gives EXTURN the necessary stability. Thus, the required space in the interior of the boat, the assembly work and assembly costs are reduced to a minimum.
With its cross section starting from 6.5 inch, with 22 inch length, the EXTURN thruster is mountable onto every place of the hull and every hull shape (v-hull, fl at hull, etc.) in only a few hours, even during the season. This provides unprecedented flexibility to both sailboats and motorboats. Optimal efficiency is reached by the extremely short transverse channel of the thruster. The engines are cooled and protected against overheating
as they are in water, which also keeps engine noise to a minimum. MARINNO offers models starting from 44 lbf to 265 lbf, in 12V and 24V variants and for boats up to a length of 66 feet. The EXTURN thruster can be controlled optional by touch panel, joystick or radio remote control.
Unequaled safety and comfort
“The external bow thruster was originally developed for our own needs, to guarantee more safety and comfort,” reveals boat freak Hubert Holesz, MARINNO shareholder and responsible for R+D. “However, it worked so well that we wanted to also offer it to other boat lovers and hobby sailors. All tested boats kept course much more easily and ran at higher levels. Also, any kind of port maneuvers, no matter in which weather, represented no more problems,” says Holesz. Thus, the EXTURN bow and stern thruster bridges
perfectly functionality and luxury for affordable expenditure. This combination of safety and comfort remains unequaled by all other well-known systems.
With its external thruster EXTURN, MARINNO begins a whole series of new and convenience-oriented products, which, in the near future, will provide much joy for sailors, not only at sea, but also when easily and independently rigging their “jewel”.
