Having a bow thruster
gives you positive control of your boat, even at low speed and
regardless of wind, current or tight docking conditions. Vetus
offers both electrically and hydraulically driven bow thrusters, to
suit a wide variety of boats. Working in close collaboration with
the Maritime Institute Netherlands (MARIN), the world-famous
hydrodynamic laboratory, Vetus has optimized the performance of its
thrusters. This has been achieved by utilizing a unique propeller
blade profile, which creates little or no cavitation. As
cavitation produces unwanted noise, this new blade design offers a
major reduction in the operating sound levels for Vetus bow
thrusters. Moreover, the application of this new propeller has
reduced the current consumption by up to 10%.
Vetus bow thrusters are
equipped with a streamlined bronze tail piece. This has proven to be
stronger and more durable than other materials sometimes used, while
creating the minimum of turbulence, lowest efficiency loss and
lowest noise levels. The metal underwater parts are protected
by a zinc anode, which is fitted as standard. Vetus propellers are
corrosion-free and on thrusters up to the 310 kgf model, are made of
synthetic materials. Owing to their low weight, the maximum thrust
force is obtained very quickly and with a minimum of energy. The
propeller blades are specifically designed for use in a tunnel and
are shaped in such a way that the thrust is equal to both starboard
and port. Because of this, cavitation is largely avoided and noise
levels are considerably reduced. Thruster models over 310 kgf have
bronze propellers as standard, for increased strength and
durability. |
